Welding cracksThe most common serious defect in welded parts. Under the combined effect of welding stress and other brittle factors, the bonding force of metal atoms in local areas of the welded joint is destroyed, resulting in a new interface gap. It has the characteristics of sharp notches and lar

(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.
