Read MoreStraight seam welded pipe: a steel pipe with the weld seam parallel to the longitudinal direction of the steel pipe. According to the forming process, it is divided into high frequency straight seam steel pipe (erw pipe) and submerged arc welded straight seam steel pipe (lsaw pipe). 1. Construction preparation before use of straight seam welded pipe The pipeline…
Read MoreOil casing pipe is the lifeblood of keeping oil wells running. Due to different geological conditions, the downhole stress state is complex, and the comprehensive action of tension, compression, bending and torsional stress acts on the pipe body, which puts forward higher requirements on the quality of the casing itself. Once the casing itself is damaged for some reason,…
