Abstract: The Yangqu Raw Water Direct Supply Project, part of the Shanxi Wanjiazhai Yellow River Diversion Project, successfully completed the installation of DN1000 ductile iron pipelines using...

Abstract: Owing to their excellent mechanical properties and corrosion resistance, ductile iron pipes are widely used in municipal water supply, gas transmission, and industrial fluid transportation....

Abstract: Leakage in ultra-high-pressure steam pipelines is a common issue in ethylene plants. This study investigates the causes of leakage in an ultra-high-pressure pipeline at an ethylene...

Abstract: Microscopic morphology observations and thermodynamic analysis indicate that the delamination defects in 374.65 mm × 18.65 mm 110S casing resulted from an excessive concentration...

Abstract: This paper examines the formation of oblique weld cracks in square tubes made from Q355B low-alloy hot-rolled steel strip and analyzes the underlying causes. A 7.75 mm steel strip...

Abstract: ASTM A370-2022 requires surface removal for impact specimens, which conflicts with ASME B31.3-2022, where undercooling must be considered if the notch width is less than 80% of the material...

Abstract: This study investigates weld seam cracking that occurred during the flaring process of 441/2D plate welded pipes produced by Jiugang and provides a comparative analysis with materials from...

Abstract The safe operation of residential community water supply systems is closely tied to the proper selection of pipes and fittings. This study examines the technical regulations designed to...

Abstract This study examines the production process, associated challenges, implemented countermeasures, and performance characteristics of high-alloy Cr-Mo steel plates for high-temperature-resistant...

Abstract: To improve the stability and safety of water supply systems, a construction plan for a submarine water pipeline was developed. Using the Zhanjiang Jianjiang Water Supply Hub Project...
