Abstract:
Piping systems handling high-pressure and high-velocity steam and various process and hydrocarbon gases through a pressure-reducing device can produce severe acoustic vibration and metal fatigue in the system. It has been previously shown that the acoustic fatigue of the piping system is governed by the relationship between fluid pressure drop and downstream Mach number, and the dimensionless pipe diameter/wall thickness geometry parameter. In this paper, the devised relationship is extended to cover acoustic fatigue considerations of medium and smaller-diameter piping systems.

Abstract:
A design for a 26 000-shp standardized coal-fired steam turbine propulsion plant using product work breakdown structure (PWBS) or group technology techniques was developed for the Maritime Administration. The purpose of the design was to provide a design package for a production approach which could reduce machinery outfitting cost and time by one third. Emphasis was placed on piping within the main machinery space. In the concept and preliminary design phases, the machinery box was developed to fit within the hull lines of an 80 000, 144 000, and 180 000-dwt collier. Propeller size, shaft line, and rpm were defined; the steam cycle was selected; and initial machinery arrangements were developed for both a dual boiler and a single boiler plant. During contract design, machinery specifications, schematic diagrams, arrangements, and procurement specifications were developed. In production design, standards were developed, schematic diagrams were revised, and piping diagrammatic arrangements, composites, material lists, and purchase orders for components were prepared. A production philosophy and build strategy also were developed. This effort made use of the PWBS approach presented in the MarAd National Shipbuilding Research Program reports[1–5]3

Abstract:
Piping systems adapted for handling fluids such as steam and various process and hydrocarbon gases through a pressure-reducing device at high pressure and velocity conditions can produce severe acoustic vibration and metal fatigue in the system. It has been determined that such vibrations and fatigue are minimized by relating the acoustic power level (PWL) to being a function of the ratio of downstream pipe inside diameter D2 to its thickness t2. Additionally, such vibration and fatigue can be further minimized by relating the fluid pressure drop and downstream Mach number to a function of the ratio of downstream piping inside diameter to the pipe wall thickness, as expressed by M2 Δp = f(D2/t2). Pressure-reducing piping systems designed according to these criteria exhibit minimal vibrations and metal fatigue failures and have long operating life.

Abstract:
Most domestic fossil power plants have exceeded 100,000hours of operation with the severe operating condition. Also, cyclic operation of the plant subjects the piping system to mechanical and thermal fatigue mechanisms and poor of defective support assemblies can impose massive loads onto the piping system and induce unstable piping displacement. In order to prevent the serious damage and failure of the piping system in fossil power plants, 3-dimensional displacement measurement system was developed for the on-line monitoring. Displacement measurement system was developed with LVDT and rotary encoder type sensors. This system was installed and operated on a real power plant successfully.

Abstract:
Dynamic transients such as steam hammer or water hammer in power plant or process piping can generate high destructive reactions if rigid restraints or snubbers are used in an attempt to exert total control of pipe response. However, where some movement can be tolerated, adequate control can be maintained with much lower resulting loads in the restraining structures and components. The disk spring restraint has been demonstrated to be a practical device for controlling piping movements caused by typical dynamic upset conditions in steam and boiler feedwater piping and in drain lines carrying mixed phase (water and vapor) flow. This paper discusses the simplified mathematics used in estimating loads to design disk spring restraints for such applications.

The main goal of this thesis is to get an insight into a field of non-destructive testing using potential drop techniques that have nowadays become the standard not only in the fatigue and loading tests but also in the industry. These methods can serve to non-destructively and continuously measure material specimens, thickness, corrosion losses, deformations, spectroscopy and detection and analysis of crack geometry. They can help to identify materials and measure material changes over time. The second part of this thesis deals with designing the aperture for detection of cracks in steam and product piping using potential drop technique modified by Ing. Ladislav Korec, CSc. Last part deals with extensive testing, experimenting and evaluation of the aperture.

Abstract:
Steam exploded fibers from Yellow Poplar (Liriodendron tulipifera) wood were assessed in terms of (a) their impact on torque during melt processing of a thermoplastic cellulose ester (plasticized CAB); (b) their fiber incorporation and dispersion characteristics in a CAB-based composite by SEM and image analysis, respectively; and (c) their impact on the mechanical properties (under tension) of CAB-based composites having fiber contents of between 10 and 40% by weight. The fibers included water-washed steam exploded fibers (WEF), alkali-extracted fibers (AEF), acetylated fibers (AAEF), all from Yellow poplar (log Ro = 4.23), and oat fillers (COF) as control. The stepwise increase in cellulose content by extraction, and especially the (surface) modification by acetylation, contributed to increased torque during melt processing, and to improved interfacial adhesion as well as fiber dispersion. As compared to pure CAB, AAEF generated the highest increase in torque (+ 421%) followed by AEF (+ 260%) and WEF (+ 190%) at 40% fiber content by weight. AAEF was also found to enhance the tensile properties of the resulting composites. SEM studies of the tensile fracture surfaces indicated significant interfacial delamination and also pull - out of fibers when WEF, AEF, and COF were used to reinforce the CAB matrix. Composites with AAEF, by contrast, revealed fracture surfaces with reduced interfacial delamination and with significant fiber fracturing during failure. Image analysis was used to determine fiber dispersion within the resulting composites quantitatively. Significant improvement in fiber dispersion was achieved when the matrix was reinforced with acetylated fibers (AAEF). Fiber addition to the matrix resulted in loss of strain at break (- 80 to - 93%) and slight or significant increases in modulus (+ 47 to + 103%) depending on fiber type at 40% fiber content. Maximum stress declined for all fibers except AAEF at all fiber contents. AAEF-based composites revealed a decline in maximum stress when fiber content rose to 10%, and this reversed when fiber content increased beyond 10%. This increase in strength is consistent with the rule of mixtures that stipulates reinforcement of the matrix by fibers that are capable of transferring stresses across the fiber-matrix interface. All fibers suffered length decreases during melt processing.

Abstract:
Carregamentos transientes termo hidráulicos do tipo Steam Hammer são eventos comuns em sistemas de tubulações de vapor com grandes potenciais de catástrofes em plantas de geração de energia. Uma vez iniciado o evento, ondas de pressões são geradas com amplitudes, geralmente, de grande magnitude ocasionando altas pressões no sistema, ruídos, deformações, fadiga, com possibilidade de danos materiais e econômicos e em casos extremos fatalidades. Os procedimentos da indústria para análise deste tipo de sistema consistem realização de análises estáticas equivalentes ou análise de espectro de resposta com carregamentos caracterizados por meio de métodos analíticos baseados em hipóteses simplificadoras do fluido e fluxo. Neste trabalho é proposta a analise de sistema de tubulações por meio do método de integração numérica com superposição modal e carregamento caracterizado por método numérico com base no método das características. Comparações foram efetuadas entre os resultados obtidos pela metodologia proposta e os procedimentos da indústria, demonstrando que, dado ao alto grau de conservadorismo, os procedimentos da indústria acarretam em superdimensionamento de estruturas e tubulações ocasionando custos adicionais de projeto, sendo a otimização do projeto obtida aplicando-se a metodologia proposta no trabalho.
Steam Hammer is a common transient thermo hydraulic event in steam piping systems with potential to cause serious damages in power generation plants. It generates pressure waves, generally of great amplitude and magnitude, causing high pressures in the system, associated with noise, with possible material and economic damages and, in extreme case, even fatalities. Industry procedures for analysis of these events consists of performing equivalent static analysis, or response spectrum analysis, with transient loadings calculated by analytical methods based on assumptions of fluid and flow. This paper proposes a new methodology for the piping system analysis by the numerical integration method with modal superposition and transient loadings calculated by a numerical method based on the method of characteristics. Comparisons were made between the results obtained by the proposed methodology and the stablished industry procedures, confirming that, due to the high degree of conservatism, industry procedures can lead to additional cost to the design, with the optimization of the design being obtained by applying the methodology proposed in this paper.

Abstract:
The commercial pressure frying has been limited to frying huge amount of products due to its dependence on the amount of moisture released from the food for generating the desired pressure. This study investigated the feasibility of using nitrogen gas as a substitute for steam in the pressure frying system. The effects of various process conditions (source of pressure, frying temperature and pressure) on fried product and frying oil qualities were evaluated. Frying experiments were performed on breaded/battered poultry products including chicken nuggets (homogenous) and chicken fillets (marinated, intact muscle). Efforts were also made to develop rapid methods to determine frying oil quality and discriminate among fresh, marginal and discarded oils using a chemosensory (also known as electronic nose) or Fourier transform infrared spectroscopy (FTIR-ATR). Frying temperature and pressure affected fried food quality. An increase in frying pressure resulted in tender, juicier products with less oil uptake due to high moisture retention. An increase in frying oil temperature resulted in an increased moisture loss, oil uptake resulting in less tender and juicier products. Compared with frying using steam released from food, using nitrogen provided similar or better quality fried products in terms of moisture retention, juiciness and texture. The reused oils from the fryer using nitrogen gas was better in quality than the system using steam as evidenced from the physical, chemical and chemosensory measurements.

Abstract:

The development in the steam turbine business is heading for applications with much higher steam parameters since this enables a raised efficiency. Steam parameters refer to the pressure and the temperature of the steam. The aim of this study was to generate concepts for steam turbine inlet control valves designed for higher pressure and temperature in comparison with the present design. Future steam power plants using solar energy, based on tower technology, request this kind of performance and are an important potential market.

This master thesis at Linköping University has been written in collaboration with Siemens Industrial Turbomachinery AB. The performed work has incorporated literature studies, functional analysis and solid mechanics analysis, flow analysis, evaluation of sealings and cup springs and development of the dimensioning data for the future control valve. The aim was to find a design concept that sustains the new and higher steam parameters and is tolerant concerning vibrations.

A systematical way to work has been applied during the project and a detailed planning was continuously followed and adjusted. Major methods used were product design specification, quality function deployment, morphological matrices, decision matrices and failure mode and effect analysis. Important programs used during the project were Pro/ENGINEER, MATLAB, FloEFD and MS Excel.

Today’s valves are dimensioned for much lower performance than the new requirements in terms of pressure and temperature. The main problem for the present design is that the opening and closing forces requirements, with the new higher pressure, get unreasonably large. Therefore were many of the developed concepts equipped with a pressure balancing feature. This feature also gives another desirable result; the vibrations (that is the source of many of the problems with the present design) will also be reduced.

During the early concept development phase, 15 different concepts were generated and after the concept evaluation only three concepts remained. These concepts were further developed in different areas of interest and finally one of the three was chosen to be the winning concept. The new valve design will most likely meet the requirements and has the potential to be refined for even higher pressure for future demands.


Utvecklingen inom ångturbiner går mot applikationer med mycket högre ångdata eftersom detta möjliggör en ökad effektivitet. Ångdata refererar till ångans tryck och temperatur. Uppgiften var att generera koncept för inloppsreglerventiler (till ångturbiner) dimensionerade för högre tryck och temperatur jämfört med dagens design. Framtida ångkraftverk som drivs av solenergi, så kallade soltorn, efterfrågar denna prestanda och är en viktig framtida marknad.

Detta examensarbete vid Linköpings Universitet har skrivits i samverkan med Siemens Industrial Turbomachinery AB. Det genomförda arbetet har innefattat litteraturstudier, funktionsanalys och hållfasthetsanalys, flödesanalys, utvärdering av tätningar och tallriksfjädrar samt framtagning av dimensioneringsunderlag för den framtida reglerventilen. Målet var att finna ett koncept som klarar av dessa nya och högre ångdata och är tåligt beträffande vibrationer.

Ett systematiskt arbetssätt har anammats under projektet och en detaljerad planering upprättades och uppdaterades kontinuerligt. Viktiga metoder som använts är PDS (Product Design Specification), QFD (Quality Function Deployment), morfologisk matris, relativ beslutsmatris och feleffektanalys. Viktiga program som använts i projektet är Pro/ENGINEER, MATLAB, FloEFD och MS Excel.

Dagens ventiler är dimensionerade för mycket lägre prestanda än de nya kraven kräver i termer av tryck och temperatur. Det huvudsakliga problemet med den nuvarande designen var att kraven på de öppnande och stängande krafterna, med dessa nya ångdata, blir orimligt höga. Därför har många av de framtagna koncepten utrustats med tryckbalanserande funktion. Denna funktion ger också ett annat önskvärt resultat; vibrationerna (som är källan till många problem med dagens design) kommer även de att reduceras.

Under den tidiga konceptutvecklingsfasen genererades 15 olika koncept och efter konceptutvärderingen återstod bara tre. Dessa koncept vidareutvecklades inom olika intressanta områden och slutligen valdes ett av koncepten som det vinnande. Den nya ventildesignen kommer med stor sannolikhet att uppfylla kraven och har potential att förfinas för ännu högre tryck för framtida krav.

Abstract:
Les cinetiques d'oxydation a haute temperature de nombreux metaux et alliages metalliques, ainsi que la morphologie des couches de corrosion formees, peuvent etre tres influencees par la presence de vapeur d'eau dans l'atmosphere oxydante. Cependant l'interpretation des resultats est la plupart du temps vague et les mecanismes d'oxydation restent mal connus. Pour porter un eclairage nouveau sur ce domaine de la cinetique heterogene, cette these tente de relier les aspects classiques de modelisation macroscopique de l'oxydation thermique des metaux et ceux, plus novateurs, de perception microscopique des phenomenes physiques impliques. Pour ce faire, nous avons mene une etude cinetique parametrique et une caracterisation des couches utilisant notamment les methodes photo-electrochimiques ex-situ, dans le cas du nickel et du titane. Pour la premiere fois, l'utilisation systematique de la photo-electrochimie, apporte des eclairages inattendus sur les ecarts a la stoechiometrie, le niveau de contrainte et la nature des defauts des oxydes formes. Ces resultats permettent de proposer une modelisation cinetique en accord avec la totalite des observations experimentales

Abstract:
Piping systems handling high-pressure and high-velocity steam and various process and hydrocarbon gases through a pressure reducing device can produce severe vibration of the piping system and noise and pulsation in the surroundings. Utilizing the data published by Carucci, V.A., and Mueller, R.T., 1982, “Acoustically Induced Piping Vibration in High Capacity Pressure Reducing Systems”, ASME Paper No. 82-WA/PVP-8, we develop a relationship for acoustic power and acoustic pressure as a function of the product of the Mach number M and pressure drop Δp (MΔp) through the system. Thirty six cases were evaluated to formulate this relationship.

Abstract:
Based on recent laboratory experimental data by Feenstra et al. [1],[2] it has been determined that for larger test section widths, the maximum acoustic pressures generated during acoustic resonance were greater by more than a factor of four than those predicted by Blevins and Bressler [3]. We have evaluated a great number of resonant and non-resonant cases from inservice experience of full size steam generator and tubular heat exchanger tube banks in order to see the general vibratory behavior of the full size units. Fifteen vibrating and twenty-seven non-vibrating cases were evaluated and compared to the Feenstra et al. relationship. It is shown that on average the results from the full size units correlate well with the Feenstra et al. relationship. A gap exists between the vibratory and the non-vibratory cases. The non-vibratory cases produce acoustic pressures which are at or below the Blevins and Bressler relationship. From the results it can be concluded that the full size units, regardless of their size and also acoustic mode, produce high acoustic pressures at resonance, with the maximum acoustic pressure on average more than fifty to seventy five times higher than the input energy parameter defined by the product of Mach number and pressure drop through the tube bank. The results are tabulated and plotted for comparison.

Abstract:
Many utilities select critical welds in their main steam (MS) and hot reheat (HRH) piping systems by considering some combination of design-based stresses, terminal point locations, and fitting weldments. The conventional methodology results in frequent inspections of many low risk areas and the neglect of some high risk areas. This paper discusses the use of a risk-based inspection (RBI) strategy to select the most critical inspection locations, determine appropriate reexamination intervals, and recommend the most important corrective actions for the piping systems. The high energy piping life consumption (HEPLC) strategy applies cost effective RBI principles to enhance inspection programs for MS and HRH piping systems. Using a top-down methodology, this strategy is customized to each piping system, considering applicable effects, such as expected damage mechanisms, previous inspection history, operating history, measured weldment wall thicknesses, observed support anomalies, and actual piping thermal displacements. This information can be used to provide more realistic estimates of actual time-dependent multiaxial stresses. Finally, the life consumption estimates are based on realistic weldment performance factors. Risk is defined as the product of probability and consequence. The HEPLC strategy considers a more quantitative probability assessment methodology as compared to most RBI approaches. Piping stress and life consumption evaluations, considering existing field conditions and inspection results, are enhanced to reduce the uncertainty in the quantitative probability of failure value for each particular location and to determine a more accurate estimate for future inspection intervals. Based on the results of many HEPLC projects, the author has determined that most of the risk (regarding failure of the pressure boundary) in MS and HRH piping systems is associated with a few high priority areas that should be examined at appropriate intervals. The author has performed many studies using RBI principles for MS and HRH piping systems over the past 15 years. This life management strategy for MS and HRH critical welds is a rational approach to determine critical weldment locations for examinations and to determine appropriate reexamination intervals as a risk-based evaluation technique. Both consequence of failure (COF) and likelihood of failure (LOF) are considered in this methodology. This paper also provides a few examples of the application of this methodology to MS and HRH piping systems.

Abstract:
The goal of this research is to improve our understanding of the effects of a postulated Main Steam-Line Break on the transient loading of nuclear steam generator tubes. The analysis of this problem deals with the complex coupling of rapid transient two-phase flow dynamics and fluid-structural loading processes. A main concern of nuclear reactor safety is to ensure that radioactive materials produced by nuclear fission are safely contained. This type of accident produces a ‘blowdown’ in which the pressurised water in the steam generator is boiled off in a few seconds. The resulting transient loading on the steam generator tubing could lead to their rupture, resulting in the release of radioactive materials out of containment. A better understanding of this phenomenon will permit the development of improved design tools to ensure steam generator safety in the event of such an accident. This paper presents a work in progress, describing the purpose-built experimental facility and a summary of commissioning results, including an evaluation of the instrumentation and data collection methodology. The final results of this research will provide physical insights and guidance for the development of predictive modelling tools.

Abstract:
If the main steam line from a nuclear steam generator were to break, the water in the steam generator would rapidly flash off in what is called a blowdown. Such an event could produce significant loading on the steam generator tubes, which if fractured, could lead to a loss of radioactive materials from containment. Thus, knowing the tube loading during such an event is an important input for safe design. This paper presents the results of an experimental laboratory study of the transient tube loading during a simulated blowdown. The working fluid was R-134a and the sectional tube model was a normal triangular array with a pitch ratio of 1.36. Tests were conducted with various levels of liquid R-134a and various numbers of tube rows. The transient tube loading is explained in terms of the associated flow physics and the maximum load is compared with existing models for tube loading obtained under steady flow conditions.

Full text
Abstract:
Safety valve closure is employed within power plant piping systems to protect sensitive components from damage due to irregular events causing abrupt pressure variations of the thermal fluid flow. The valve closure creates a sudden obstruction to the flow, generating a pressure wave within the fluid which travels upstream and impacts at the pipe elbows. Such an event is known as steam hammer. This steam hammer pressure wave is capable of producing significant loads and stresses which can disrupt the piping supports as the wave travels throughout the pipe system. Previous studies have shown that the magnitude of these transient loads depend upon the characteristics of the flow, valve closure time, elbow-to-elbow pipe section lengths, the piping system flexibility, and the ‘steepness’ of the pressure transient. The latter effect has been ignored in most steam hammer studies; however, wave steepening has been shown to have a significant effect in cases where the pressure wave travels long distances from the safety valve. This study focuses on Computational Fluid Dynamics (CFD) modeling of rapid valve closure to produce this wave steepening effect and to investigate the significance in terms of transient pipe support loads.

Abstract:
High levels of tonal noise continue to be a potential problem for piping systems that include inline gate valves, particularly for valves located in large-diameter steam lines of power plants. In such cases the large amounts of energy available in the flowstream, and the ineffectiveness of design guidelines in avoiding acoustic excitation, combine to provide a very real possibility of severe noise problems and potentially high levels of piping vibration. This paper presents results of a scale-model testing program designed to investigate the excessive noise and vibration produced by a 28"-diameter gate valve in a recently constructed power plant. After model testing of the original valve configuration indicated that the noise was caused by vortex shedding over the valve’s interior cavity, numerous tests were conducted to investigate the dependence of noise production on interior valve geometry. Results showing how the noise was reduced and recommendations for avoiding such problems are presented.

Abstract:
This paper presents an evaluation of the failure probability and cost of high energy piping (HEP) failures. Using a conventional definition of risk as the product of failure probability and failure consequence, we propose in this paper a dollar value of consequence in order to develop a quantitative approach to risk-based inspection (RBI) methodology. A 16-year historical database of probability and consequence was evaluated as an RBI methodology for devising a life management strategy for welds in main steam and hot reheat piping systems. This evaluation provides us the raw data necessary for producing a concrete example of this new Richter-scale-like approach. Uncertainty in consequence and probability estimates is also provided in plotting (a) a static consequence vs. likelihood diagram at a specific time for comparing the relative severity of a variety of potential failures, and (b) a dynamic risk vs. time diagram for a specific hardware under continuous monitoring where the effect of life management decisions over a period of time is quantitatively displayed. Significance of this new approach to risk-based inspection strategy for advancing the state-of-the-art of managing aging structures is discussed.

Abstract:
The dismantling of nuclear plants is a complex activity that originates often a large quantity of radioactive contaminated residue. In this paper the attention was focused on the PHADEC (PHosphoric Acid DEContamination) plant adopted for the clearance of Caorso NPP (in Italy) metallic systems and components contaminated by Co60 (produced by the neutron capture in the iron materials), like the main steam lines, moisture separator of the turbine buildings, etc. The PHADEC plant consists in a chemical off line treatment: the crud, deposited along the steam piping during life plant as an example, is removed by means of acid attacks in ponds coupled to a high pressure water washing. Due to the fact that the removed contaminated layers, essentially, iron oxides of various chemical composition, depend on components geometry, type of contamination and time of treatment in the PHADEC plant, it becomes of meaningful importance to suggest a procedure capable to improve the control of the PHADEC process parameters. This study aimed thus at the prediction and optimization of the mentioned treatment time in order to improve the efficiency of the plant itself and to achieve, in turn, the minimization of produced wastes. To the purpose an experimental campaign was carried out by analysing several samples, i.e. taken along the main steam piping line. Smear tests as well as metallographic analyses were carried out in order to determine respectively the radioactivity distribution and the crud composition on the inner surface of the components. Moreover the radioactivity in the crud thickness was measured. These values allowed finally to correlate the residence time in the acid attack ponds to the level of the achieved decontamination.

Abstract:
The present paper exposes the main directions of a R&D program that DCN and CEA are currently developing to study the dynamic response of the steam generator of a naval nuclear propulsion reactor submitted to a shock. The structure is composed of tube bundles, immersed in a two phase flow fluid (steam and water). The dynamic solicitation contains high accelerations and high frequencies. It is thus necessary to establish which kind of physical phenomena can take place, and which kind of numerical tool can be used to study the dynamic behavior of the system. If the acceleration and the frequencies are very high, it will be necessary to consider highly non linear physical phenomena, with large deformation within short time duration. If the acceleration and (or) the frequencies are lower, simpler methods can be considered, assuming a linear behavior for the structure. In the latter case, as the frequencies still remain higher than the seismic ones, it might be necessary to take into account different kind of eigenmodes, as those depending on the fluid compressibility. As the fluid is a two phase medium, the use of homogenized fluid model has to be investigated. Since the tube bundle is a periodic structure, a homogenization technique can be used. Basic principles of the method are recalled as well as potential developments of existing methods. Influence of dissipative effects has also to be evaluated. The paper exposes the various problems that have to be addressed in order to produce a physical model of the structure that takes into account the various fluid-structure interaction effects for the shock analysis of the steam generator.
