High Quality. SGS inspection is accepted if needed
Foodstuff, Gas, metallurgy, biology, electron, chemical etc.
We can also do other materials
321 stainless steel pipe seamless steel pipe (GB3087-1999) is used in the manufacture of various structural low intermediate pressure boiler superheated steam pipe, water pipe and locomotive boiler superheated steam pipe, pipes, small pipe and arch brick works of high quality carbon structural steel hot rolling and cold drawing (rolling) seamless steel tube.
321 stainless steel pipe: mainly used in the manufacture of high pressure and over pressure steam boiler pipes, etc. With high quality carbon structural steel, alloy steel and stainless heat resistant steel seamless steel tube, the boiler tube by the party under high temperature and high pressure pipe and works in high temperature flue gas and steam will happen under the action of oxidation and corrosion, so the steel pipe with high rupture strength, high oxidation resistance, and have good organizational stability, hydraulic prop.
Tensile strength of sigma b (MPa) : p. 520
Conditions to yield strength sigma (0.2 MPa) : p. 205
Elongation delta (%) : 40 or higher
Reduction of area bits (%) : 50 or more
Hardness: 187 hb or less; 90 HRB or less; 200 hv or less
we pack our pipe by waterproof paper , then we put these goods into wooden box. the length of our pipe is 6-11m, so we advice load our pipe by 40GP container.
Here is the packing picture of us
Our seamless stainless steel tube display
Heat and corrosion resistance
Fine mechanical properties
Great intensity in low temperature
No hardening phenomenon when in heat treatment
Good hot workability such as in stamping and bending
