(1) Automatic tube rolling productionOne of the ways to produce seamless steel pipes. The production equipment consists of a piercing machine, an automatic tube rolling machine, a leveling machine, a sizing machine, and a reducing machine. The production process is shown in the figure.(2) Continuous

Seamless steel pipe, straight seam welded steel pipe, forged steel pipe, precision steel pipe, high-precision precision steel pipe, etc. steel pipes will cause different degrees of curves in the longitudinal direction (i.e. length direction) of the steel pipe body during the production process.

304L stainless steel cold-rolled sheet is transformed into stainless steel products through various processing techniques and then applied to various industries. But do you know how to solve the problem if the performance of 304L stainless steel cold-rolled sheet is impaired?1. The lattice dislocati

There are the following reasons for weld cracking during welding:Stress, constraint, rigidity, chemical composition, gap reserved for weld, current, weld bead, cleanliness of parent material, etc. These factors may cause weld cracking.Although there are many reasons for weld cracking, it is caused b
