This study investigates residual materials in the railway construction project. The Fishbone Diagram method identifies factors causing material waste, while the Waste Hierarchy guides material management by contractors. The remaining materials include spun piles, ballast stopper cover plates, wiremesh, concrete pad anchoring systems, and PVC pipes. The quantities are 1306.5 meters of spun pile, 86 ballast stopper cover plates, 4 wire mesh sheets, and a concrete pad anchoring system with 160 e-clips, 160 insulators, 80 rail pads, and 7 pieces of 6-inch diameter PVC pipe, along with 13 pieces of

Abstract:
The backfill quality of a pipeline has an important influence on pipeline operation. When loose backfill is used, the pipeline may be damaged after short term operation. In this study, the numerical simulation analysis of buried pipes was carried out under three conditions: loose backfill around the pipe, dense backfill, and controlled low strength materials (CLSM) backfill. The effects of narrow trench backfilling using CLSM on the force and deformation of pipelines were studied. The results showed that When CLSM was used for buried pipe backfilling, the pressure on the top of the pipe and on

Drinking water distribution systems (DWDSs) may be contaminated to various degrees when different microorganisms attach to the pipe walls. Understanding the characteristics of biofilms on pipe walls can help prevent and control microbial contamination in DWDSs. The biofilm formation, interspecific interactions, and chlorine resistance of 10 dual-species biofilms in polyethylene (PE) and cast iron (CI) pipes were investigated in this paper. The biofilm biomass (heterotrophic bacterial plate count and crystal violet) of dual species in CI pipes is significantly higher than that in PE pipes, but

Abstract:
Methods including ASME B31G, Modified ASME B31G and RSTRENG and LPC have been developed, validated and matured to the extent that they are now incorporated in standards and regulatory requirements. However, these methods are based on the assumption that the pipe fails via a ductile mechanism, i.e., the line pipe material has sufficient toughness to prevent a toughness dependent failure. This limits the application of the existing methods to materials that have sufficient toughness.�A modeling study has been undertaken in the present project using the local approach to brittle fracture to predi

The objective of this work is to: - Summarize, in spreadsheet format, historical API pipe specification requirements related to metallurgical attributes of the pipe, - Collect pipe property data for a wide range of pipe sizes, grades, and vintages, - Solicit subject matter expert input regarding the likelihood that pipe surface features and other attributes are sufficiently unique to allow pipe manufacturer and/or grade to be unambiguously determined, and to - Describe nondestructive in-situ analysis methods that can be used on operating pipelines to determine metallurgical properties.

Abstract:
Much work has been done to assess constraint effects on the crack-driving force for specimens and cracks in pipes. The material's transition temperature where the fracture process changes from ductile tearing to cleavage fracture at crack initiation is affected by the constraint conditions but is a material property that cannot be determined analytically. This paper presents a methodology to account for constraint effects to predict the lowest temperature where ductile fracture initiation occurs and relates that temperature back to Charpy impact data for X60 and lower grades, particularly for

Abstract:
It is understood that this work relates to issues arising from a failure in a pipe carrying wet sour gas, in which cracking developed from a shallow hard feature, 1 to 3mm deep and about 50mm in diameter. The overall aim is to prevent such failures, and samples of material from this program, selected on the basis of the work reported here, have been subjected to sour testing under PRCI project SSC-2-14, and there is also a link to PRCI project NDE-4-11, which is exploring non-destructive techniques for the detection of local hard regions. This report presents the techniques used in the assessm

Abstract:
Integrity assessment of pipelines is vital to ensure that oil and gas pipes have adequate strength to prevent leaks and ruptures. Regular inspections are conducted to confirm safe operation conditions of pipelines. The industry's principle method for assessing pipelines is in-line inspection (ILI), involving the passing of a device along the inside of a pipe to assess the condition of the pipeline. ILI devices can be fitted with a number of sensors allowing various measurement parameters to be obtained simultaneously. Not all pipelines are suited to ILI for reasons such as small diameter, obst
