Product introduction

Product characteristics

What is 321 stainless steel pipe?

321 stainless steel tubes are hot-rolled and cold-drawn (rolled) seamless steel tubes of high quality carbon structural steel used in the manufacture of superheated steam tubes, boiling water tubes and superheated steam tubes for locomotive boilers of various structures, large smoke tubes, small smoke tubes and arch brick tubes for low and medium pressure boilers.

These boiler tubes often work at high temperatures and pressures, and the tubes are also subject to oxidation and corrosion under the action of high temperature flue gas and water vapour, so the steel tubes are required to have high enduring strength, high oxidation resistance, and good organisational stability, hydraulic pillar tubes.

321 stainless steel tubes are delivered in heat-treated condition. In addition, the microstructure of the finished steel pipe, grain size, decarburization layer also have certain requirements. Seamless steel tubes for geological drilling and oil drilling control; used for exploring underground rock structures, groundwater, oil, gas and mineral resources, using drilling rigs to drill wells.
