Description:

Stainless steel description
Stainless steel is an alloy of iron that contains chromium and other alloying metals like nickel, molybdenum, titanium, copper,carbon, and nitrogen. Stainless Steel Tubing is used in aircraft hydraulic lifts, factories, mills, production lines, fuel and heat industries, military, nuclear development, etc. The stainless steel pipes & tubes available in various grades such as 304, 316L, 309S, 310S, 317L, 321, 321H, 347H, 316Ti are used for manufacturing.

Stainless Steel Seamless Pipes & Tubes are formed by using Water Hydraulic Hot Extrusion Press that uses hot extruded hollows or pipes as raw material. They are used in various fields like heat exchangers, Nuclear Power Plants, Oil & Gas, Petrochemical & Refinery, Chemical & Fertilizer, etc.

Stainless steel seamless pipe is a kind of hollow long steel profile, mainly used in petroleum, chemical, medical, food, construction,mechanical instrumentation and other industrial transmission pipes and mechanical structural components. For seamless, outside diameters are from 6mm to 1400mm with wall thickness from 0.5mm to 70mm. The annual output capacity is 35,000 tons.

Applications:

321 stainless steel pipe seamless steel pipe (ASTM A312 ) 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.
