Carbon (C): The carbon content in the steel increases, the yield point and tensile strength increase, but the plasticity and impact decrease.
Read moreSeamless carbon steel pipes are made of steel ingots or solid billets through perforation to make capillaries, and then hot-rolled, cold-rolled or cold-drawn.
Read moreLSAW steel pipe is a welded pipe produced by pressing (rolling) a single medium and thick plate into a tube blank in a mold or a forming machine, using double-sided submerged arc welding and expanding its diameter.
Read moreHigh frequency resistance welded pipes are widely used. The produced steel pipe requires straight welds, no burrs, and no defects such as cracks, cracks, and unwelded welding, and the surface of the steel pipe does not exceed the specified scratches, pressure injuries and other defects.
Read moreThick-walled seamless square pipe is a square steel pipe with four corners, which is a square steel pipe formed by cold drawing and extrusion of seamless steel pipe.
Read moreStraight seam steel pipe is a welded pipe with the weld seam parallel to the longitudinal direction of the steel pipe. According to the production process, it is divided into ERW steel pipe and LSAW steel pipe.
