Submerged Arc Welding × 100 Pipeline Steels
Materials and Manufacturing Processes, 2014100 Pipeline Steels are welded by United States Lincoln double-wire welding machine. The welded joints have good weld formation and high welding quality, with no pore and crack inside. The tensile strength of the welded joint gets to 805 MPa, about 94.71%of that of the parent metal.

Hydrogen Induced Cracking in Pipeline Steels
Corrosion, 1983This paper describes the work conducted at the British Gas Engineering Research Station (ERS) using laboratory tests of the BP and NACE type to assess the hydrogen induced cracking (HIC) resistance of pipeline steels. Various grades of linepipe and fittings steels have been studied, and the metallurgical parameters controlling HIC resistance have been ...

Engineering Failure Analysis, 2018
In this research, we investigated microstructural aspects of intergranular and transgranular fatigue crack propagation in an API X65 steel pipelines. For this purpose, the fatigue testing, based on ASTM E647 Standard, was carried out on CT specimens. The

Welding X100 steels for gas pipelines
Welding International, 2004Abstract The increasing demand for high strength steel (to date not included in the standards for pipe material specifications) for dedicated long distance pipelines for natural gas transportation at high pressure (≥ 10 Mpa) has prompted studies of the overall integrity of both the pipe and the girth welds used, fundamental parts of the structural ...
