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.

each pipe PMI testing to check chemical composition
Stainless Steel Pipe Value Add
Can polish nearly any stainless steel pipe item to a #4 polish, #6 Polish, #7 polish or a #8 mirror finish.
Can bevel the edges of stainless steel pipe to prepare for welding or other processes.
Honing & Turning
Can hone pipe and tube, using a precision abrasion process in order to obtain a desired finish or close dimensional tolerance.
Heatreating & Annealing
Some grades of stainless steel pipe can be heatreated to change the mechanical properties.
Positive Material Identification (PMI)
Can perform PMI testing in house for most stainless steel grades, or we can work with independent labs to complete PMI in order to meet customer specifications.
In some cases, UT testing of the stainless steel pipes may be required.
Widely used in Petroleum, Foodstuff, Chemical Industry, Construction, Electric power,
Nuclear Energy, Biotechnology, Machinery, Paper making, Shipbuilding, Boiler fields etc.
