Product Details

Alloy seamless pipe is a kind of seamless steel pipe, and its performance is much higher than ordinary seamless steel pipe. Because this kind of steel pipe contains more Cr, its high temperature, low temperature and corrosion resistance performance can not be compared with other seamless steel pipe. Therefore, alloy pipe is widely used in petroleum, chemical, electric power, boiler and other industries.

Process flow:

Hot rolling (extrusion seamless steel tube): round tube billet → heating → perforating → three-roll diagonal rolling, continuous rolling or extrusion → pipe stripping → sizing (or reducing)→ cooling → billet tube → straightening → hydrostatic test (or flaw detection)→ marking → warehousing.

Seamless steel pipe cold drawing (rolling): round billet - heat - punch to heading, annealing and pickling to apply oil (copper),multi-channel time cold drawing (cold) and billet tube - heat treatment - straightening to hydrostatic test (NDT) - > tag, put in storage.

Application:

Alloy seamless pipe usually applied in motor, construction, oil, medicine, food, paper, machinery, washing machine, chemicals, food containers and other industries. seawater environment, petrochemical, fertilizer, oil refining, oil and natural gas, light/food, paper pulp and making paper, energy and environmental protection industry.
