Abstract:
In the pipeline construction, the girth welds tend to be the weakness because of defects and microstructure. The importance of suitable assessment of various defects in the weld is not only to prevent the cracks from unstable growth to cause catastrophic accident but also can effectively reduce the weld repair to reduce construction cost. Although many welding defects assessment methods and codes are used in this field, there are many differences among them. In this paper, the welding defect assessment methods, such as API 1104 and BS7910, were studied. The results show the key factors that af

The main focus in the non-dialytic management of patients with acute kidney injury (AKI) is the prevention and treatment of complications.Nutritional support is an important aspect as many patients tend to be hypercatabolic, thus requiring adequate caloric intake, yet without administration of excessive fluid volumes. Inadequate nutrition in AKI may lead to enhanced production of urea nitrogen and azotaemia. However, hyperglycaemia is a frequent complication in these patients, often requiring continuous insulin therapy to achieve the recommended blood glucose target range of 110–150 mg/dL (6.1

Abstract High-low misalignment in girth welds introduces local bending stress and thus can potentially have detrimental effects on the stress capacity of girth welds. However, long-term pipeline service experience demonstrates that high levels of high-low misalignment do not always lead to reductions in the safety and integrity of pipelines. This paper discusses a PRCI-funded work that aimed to understand the impacts of misalignment on the integrity of girth welds and develop rational limits for misalignment for incorporation into existing standards.

There are a number of methods that are commonly used for the assessment of a girth weld containing a ‘fabrication’ defect. These range from the more generic workmanship limits through to more complex pipeline specific Engineering Critical Assessment (ECA) methodologies. The workmanship limits stipulated in pipeline design codes can be very conservative, resulting in un-necessary and costly repairs. The ECA approach is being increasingly used to derive girth weld defect acceptance limits specific to a pipeline. These limits have been derived using either semi-analytical methods or from the resu

Abstract:
Automated ultrasonics is rapidly replacing radiography worldwide for gas pipeline girth weld inspections. Compared with radiography, mechanized ultrasonics is more reliable, faster, has better detection of critical Lack of Fusion defects, and poses no safety hazard. Phased arrays are the latest development in AUT, and present major improvements over conventional ultrasonics. Probe pans are lighter and smaller; scans are quicker due to the smaller probe pan; phased arrays are considerably more flexible for changes in pipe dimensions or weld profiles, and for different scan patterns for unusual

Abstract:
A four-metal connection, in which a carbon steel pipe is welded to duplex stainless steel pipe, is analyzed. The four metals are shown in Table 1. A106B and 2205 Duplex are the two different pipe materials, 2209 is the weld filler material, and AWSR45 is the buttering layer that is used to control the cracking susceptibility of the welded girth joint. (Butter and buttering refer to the welding of a layer of low strength material, AWSR45 in this case, and are commonly used terms within the welding community). Due to the lower strength of the AWSR45 material, the question arises whether this joi

Abstract:
An engineering critical assessment (ECA) is commonly conducted during the design of a pipeline in order to determine the tolerable sizes for flaws in the girth welds. An ECA is a method for assessing the acceptability of a flaw in a structure, i.e. to demonstrate fitness-for-service. API 579-1/ASME FFS-1 2016 and BS 7910:2013+A1:2015 Incorporating Corrigenda Nos. 1 and 2 give guidance for conducting fitness-for-service assessments of cracks and crack-like flaws. Appendix A of DNV-OS-F101, 2013 provides detailed procedures for evaluation of the fracture limit state of girth welds, based on BS 7

Abstract:
Background. Automated-entry consumer devices that collect and transmit patient-generated health data (PGHD) are being evaluated as potential tools to aid in the management of chronic diseases. The need exists to evaluate the evidence regarding consumer PGHD technologies, particularly for devices that have not gone through Food and Drug Administration evaluation. Purpose. To summarize the research related to automated-entry consumer health technologies that provide PGHD for the prevention or management of 11 chronic diseases. Methods. The project scope was determined through discussions with Ke
