Stainless Steel Seamless Pipe
Stainless steel seamless pipe is a tubular section or hollow cylinder, usually but not necessarily of circular cross-section, used mainly to convey substances which can flow — liquids and gases (fluids), slurries, powders and masses of small solids.
The high precision stainless steel seamless tubes manufactured at Hunan Great Steel Pipe begin their journey as seamless tube extrusions, in a range of different sizes. This material is reduced in size a number of times until it gradually reaches the exact specifications our customers require. Each time we perform a reduction process, the tube needs to be cut, cleaned and heat treated before the next one can commence.
