Abstract To correlate the dipole moment and density dependence of the initial magnetic susceptibility on the basis of the former related theories and the probability analysis of chain formation, physically based analytical correlation equation was derived. After the local magnetic field strength and the chaining probability between two particle have been determined the chain and particle distributions came from the geometric distribution. The initial magnetic susceptibility was resulted from the summation of Langevin initial susceptibility of k-length chains. Two particles were considered in a

Abstract:
Combined analysis of the geomorphic evolution of Greymouth with Multi-channel Analysis of Surface Waves (MASW) provides new insight into the geotechnical implications of reclamation work. The MASW method utilises the frequency dependent velocity (dispersion) of planar Rayleigh waves created by a seismic source as a way of assessing the stiffness of the subsurface material. The surface wave is inverted to calculate a shear wave velocity (Park et al., 1999). Once corrected, these shear-wave (Vs) velocities can be used to obtain a factor of safety for liquefaction susceptibility based on a des

Abstract:
Abstract The susceptibility of materials to metal dusting is dependent on several parameters, the activity of the carburizing environment, temperature, surface finish, alloy composition and pressure. This paper describes the initial test results obtained in newly developed equipment that allows the metal dusting process to be studied at pressures of up to 4 MPa. Early results show that the atmosphere and test conditions were capable of producing metal dusting in alloy 316. The severity of attack increased with increasing pressure.

Abstract This paper presents preliminary results in our effort to develop a hydrogen permeation testing method using electrochemical hydrogen charging to screen the comparative performance of candidate polymer barrier coatings as applied to pipeline steel. So-called sandwich membrane assembles with the non-conducting polymer coating located in between two conducting metallic (steel) plates were used for this purpose. Significant variation in the oxidizing current density transients was observed from the replicate testing conducted, which made it difficult to determine the more typical permeati

Abstract:
Abstract The influence of long-term heat treatments on the corrosion properties and the mechanical properties of the high-strength EN AW 6056 aluminum alloy was investigated. The alloy was tested in the solution annealed (T4) and the artificially aged (T6) condition. Additionally, both conditions were investigated after the exposure in laboratory air at 150°C for up to 38 days. The T4 treated material predominantly showed pitting corrosion in the initial state, but intergranular corrosion (IGC) was introduced during long-term aging. Furthermore, the hardness increased during the first 21 days,

Abstract The effect of potential on the susceptibility to stress corrosion cracking (SCC) of Type 316L stainless steel (SS) [UNS $31603] and Alloy 22 [UNS N06022] was determined in hot, concentrated chloride solutions using precracked compact tension (CT) specimens. In the case of Alloy 22, constant deflection tests using single and double U-bend specimens were also conducted in hot, acidified and supersaturated PbCl2 solutions. It was found that Alloy 22 is very resistant to crack initiation and propagation at an initial stress intensity of 47 MPam1/2 [43 ksi·in1/2] in 9.1 molal LiCl solution

Abstract:
The goal of this project was to develop flow charted decision processes for operators to determine when ILI is appropriate and recommended. Two initial tasks developed the background material needed for developing the decision processes. Task 1 is a review of publicly available and industry research reports pertaining to the linkage between susceptibility to crack-related failure and performing ILI. Primary references are the results from industry work that informed the development of TTO5 and the development of other industry guidance documents. Task 2 is a survey of operators to understand t

Abstract:
A challenge facing pipeline integrity groups is how to determine the number of digs required to confirm the presence or absence of SCC in a pipeline section as part of the Direct Assessment process. A Bayesian statistical methodology has been developed to solve this problem. The pro-cess requires the definition of a probabilistic susceptibility, which is the likelihood that significant SCC exists somewhere on a pipeline. The SCCDA�s probability of success to find SCC also plays a central role. Based on the initial probabilistic susceptibility (prior probability) and the SCCDA success rate, the

Abstract:
Seam cracks can pose a serious threat to the integrity of electric resistance welded (ERW) liquid and gas pipelines. Of concern to the industry is not just the assessment of cracks under service conditions, but also ways that may be used to establish the remaining lives of pipelines based on the results of a hydrostatic pressure test. An accurate crack assessment procedure is required. The main objective of Phase II is to validate the J-based crack assessment method developed in Phase I by using it to predict the results of full-scale burst tests on seam-welded pressurized pipes containing axi

Abstract:
During the qualification of procedures for welding onto in-service pipelines, for the purpose of installing repair sleeves or hot tap branch connections, heat-affected zone (HAZ) hardness is often used as an indicator of cracking susceptibility.� The objective of this project was to further develop and validate hardness evaluation criteria that can be used to quantify the trade-offs that can be made between HAZ hardness, hydrogen level, and chemical composition for welds made onto in-service pipelines.

Abstract:
One objective of this project was to gather and analyze SCC field data on lines being retested for use in assessing the validity of current or future SCC models. The scope of this initial study was limited to colonies of SCC in one valve section of a pipeline that runs from Texas to the northeast of the United States. This valve section had an early history of high pH SCC. The susceptibility since has been controlled through hydrotesting and modifications to the gas compression to meet upstream demand while reducing the discharge temperature.

�The lower-strength grades of steel used for transmission pipelines into the 60s were much like those used in other steel construction in that era. These steels gained strength by traditional hardening mechanisms through chemistry changes, largely involving carbon and manganese additions. Improvement of these grades, primarily through control of ingot chemistry and steel processing, became necessary when running brittle fracture was identified as a failure mechanism in gas-transmission pipelines in the late 50s.
