Quenching technology of straight seam welded pipe
Straight seam welded pipe surface quenching and tempering heat treatment is usually carried out by induction heating or flame heating. The main technical parameters are surface hardness, local hardness and effective hardened layer depth. Hardness testing can use Vickers hardness tester, Rockwell ...Read more -
Pipeline corrosion detection
Pipeline corrosion detection refers to in-pipe detection for the purpose of detecting metal loss such as pipe wall corrosion. The basic method used to understand the damage of the pipeline in service in the working environment and ensure that defects and damage are detected before serious problem...Read more -
Working principle of pipe jacking
Pipe jacking construction is an underground pipeline construction method developed after shield construction. It does not require excavation of surface layers, and can pass through roads, railways, rivers, surface buildings, underground structures, and various underground pipelines. Pipe jacking ...Read more -
