The development of vacuum quenching technology for 40cr precision tubes mainly lies in the development of gas cooled quenching furnaces with excellent performance and a single workstation.

Cold drawn (rolled) seamless steel pipe: round billet → heating → perforation → heading → annealing → acid washing → oil coating (copper plating) → multi pass cold drawing (cold rolling) → billet → heat treatment → straightening → hydrostatic testing (flaw detection) → marking → storage.What is cold...

The harm of cavitation in oil cylinder steel pipes is quite significant, as it can cause the mating surface to turn black, and even lead to the burning of support rings and sealing rings, resulting in internal leakage of the hydraulic cylinder barrel When cavitation and other forms of corrosion work together, it will accelerate the corrosion rate of the main parts of the oil cylinder steel pipe several times or even dozens of times
