Construction preparation (1) Operating conditions The ground of the pipeline trench is completed; the bricklaying of the pipeline well is completed. (2) Material requirements Various specifications and models of pipes are complete. (3) Main equipment Cutting machine, electric welding machine, polishing machine, electric hammer, etc. B. Quality requirements The allowable deviation of…
Read MoreDuring the processing of cold-drawn precision steel pipes, there are cold hardening and hydrogen embrittlement, which are the key reasons for the cracking of cold-drawn seamless steel pipes. Harm of cold work hardening Seamless steel pipes cause a lot of plastic deformation during cold drawing, resulting in significant changes in lattice constants, which in turn increase the kinetic energy…

Read MoreWhat is carbon steel pipe? Carbon steel pipe is also called CS pipe. Carbon steel pipes are made of steel ingots or solid round steels through perforation into capillary tubes, which are then hot-rolled, cold-rolled or cold-drawn. Carbon steel pipe plays an important role in my country’s steel pipe industry. Types of carbon steel pipes: Carbon steel pipes are…
Read MoreFor the manufacture of seamless steel tubes, the corresponding annealing treatment must be carried out after each cold drawing. Purpose of annealing: 1. Reduce hardness and improve machinability. 2. Eliminate residual stress, stabilize size, reduce deformation and crack tendency. 3. Refine the grains, improve the structure, and eliminate the defects of the structure. 4. Homogenize material organization and composition,…
