Description:
Seamless Stainless Steel Pipe is the circular, square, rectangular steel with hollow cross-sections and no surrounding joints. Seamless steel pipe generally produced by hot rolling, hot expanding, cold rolling or cold-drawing. It can be used for transmitting a large number of fluids.Seamless Stainless Steel Pipe are broadly applied in oil, gas drilling and transferring, automobile making fields. The finished products mainly include normal seamless steel pipe, low or high pressure boiler tube, alloy steel tube, and seamless stainless steel tube. Cold-rolled steel tube can get higher precision than heat treatment one.
