15CrMoV alloy pipe

15crmov alloy pipe is a kind of alloy pipe. 15CrMo steel is a heat-resistant steel with pearlite structure, which has high thermal strength and oxidation resistance at high temperatures, and has a certain resistance to hydrogen corrosion.

15crmov alloy pipe is a steel containing high content of Cr, C and other alloying elements, the hardening tendency of the steel is obvious, and the weldability is poor.

15crmov steel pipe contains more Cr, and its high temperature resistance, low temperature resistance, and corrosion resistance are not comparable to other seamless steel pipes, so alloy pipes are widely used in petroleum, aerospace, chemical, electric power, boiler, military and other industries .

15crmov alloy pipe production process:
Hot rolling (extruded seamless steel pipe): round tube blank → heating → piercing → three-roll cross rolling, continuous rolling or extrusion → tube removal → sizing (or reducing) → cooling → billet tube → straightening → hydraulic pressure Test (or flaw detection) → mark → storage.
Cold drawn (rolled) seamless steel pipe: round tube blank→heating→perforation→heading→annealing→pickling→oiling (copper plating)→multi-pass cold drawing (cold rolling)→blank tube→heat treatment→straightening→ Hydrostatic test (flaw detection) → marking → storage.
