Carbon steel welded pipes are mainly divided into three processes: electric resistance welding (ERW), spiral submerged arc welding (SSAW) and straight seam submerged arc welding (LSAW). The carbon steel welded pipes produced by these three processes have their own positioning in the application field because of their different raw materials, forming processes, caliber size and quality. 1. Straight seam…
Read MoreSeamless steel tube is an important type of steel pipe in production and life. It is an important steel that is relatively strong and durable in steel pipes. The seamless steel pipe will also encounter bending and deformation in use. When encountering the bending and deformation of the seamless steel pipe, as long as it can be corrected, the…
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,…
Read MoreWhat is an oil casing coupling? Oil casing coupling is a kind of oilfield drilling tool, mainly used for the connection of oil pipes. The oil casing coupling mainly solves the problem that the existing coupling is prone to fatigue and fracture due to stress concentration. The coupling structure of the oil casing is: the end of the oil…
