Copper bar in Cr Longitudinal weld seam on piping. - American Welding Sep 25, 2005 · The pipe rips open longitudinally until the tear comes to about 2" or 3" from the weld and then makes a 90 degree turn and tears parallel to the weld seam for another foot or so. I'm always suprised to see it as I would think the failure would be progressing with enought velocity and ferocity to continue right through the weld without even noticing.

Longitudinal-seam Submerged Arc Welded (LSAW) pipes

Longitudinal-seam Submerged Arc Welded (LSAW) pipes were made of steel plates cut from leveled hot rolled coils by both the JCOE and UOE (the forming process in which the plate like the letter J, C, O or U shape, then expansion) forming processes.

Production processes for Welded Pipes IspatGuru

Welded steel pipes are produced with either a longitudinal seam or a spiral (helical) seam. The diameters of these pipes range from around 6 mm to 2,500 mm with Selective Seam Weld Corrosion How Big is the Problem Selective seam weld corrosion (SSWC) is a type of corrosion that affects the bondline region and heat affected zone (HAZ) of the longitudinal seam of a pipeline forming grooves in the seam. The term selective refers to the preferential attack of the weld zone rather than the adjacent base metal. SSWC can be internal or external, and has been reported in both gas and liquid pipelines.
