● Execute the standards GB/T14976-2002, GB13296-91, GB9948-88 and meet American ASTM/ASME, A213/SA213, ASTM/ASME, A312/SA312, ASTM/ASME, A269/SA269, DIN 17458-85, DIN 17456-85 , JIS G 3459, JIS G 3463, JIS G 3448, JIS G 3446 standards.

● 201 stainless steel seamless tube has the characteristics of acid resistance, alkali resistance, high density and no pinholes, etc. It is a high-quality material for the production of various watch cases and strap bottom covers. 201 stainless steel pipes can be mainly used in decorative pipes, industrial pipes, and some shallow stretched products. The physical properties of 201 stainless steel pipe

● Elongation: 55 to 60%

● Tensile stiffness: 100,000 to 180,000 psi

● Elastic modulus: 29,000,000 psi

● Yield stiffness: 50,000 to 150,000 psi

פּס:201 stainless steel pipe weight formula: [(outer diameter-wall thickness)*wall thickness]*0.02491=kg/m (weight per meter).

● Structural seamless pipes are seamless pipes used for general structures and mechanical structures.

● Seamless pipes for fluid transportation are general seamless pipes used to convey fluids such as water, oil, and gas.

● Seamless tubes for low and medium pressure boilers are high-quality carbon materials used in the manufacture of superheated steam pipes, boiling water pipes for low and medium pressure boilers of various structures, superheated steam pipes for locomotive boilers, large smoke pipes, small smoke pipes and arch brick pipes. Structural steel hot-rolled and cold-drawn (rolled) seamless tubes.

● Seamless tubes for high-pressure boilers are high-quality carbon steel, alloy steel and stainless heat-resistant seamless tubes for the heating surface of water tube boilers for high pressure and above.

● High-pressure seamless pipes for chemical fertilizer equipment are high-quality carbon structural steel and alloy steel seamless pipes suitable for chemical equipment and pipelines with a working temperature of -40~400°C and a working pressure of 10~30Ma.

● Seamless tubes for petroleum cracking are seamless tubes for furnace tubes, heat exchangers and pipes in petroleum refineries.

● Steel pipes for geological drilling are steel pipes used by geological departments for core drilling. According to their uses, they can be divided into drill pipes, drill collars, core pipes, casing pipes and sedimentation pipes.

● Seamless tubes for diamond core drilling are seamless tubes for drill pipes, core rods, and casings for diamond core drilling.

● Oil drilling pipe is a seamless pipe that is thickened internally or externally at both ends of oil drilling. There are two types of steel pipes: threaded and non-threaded. The threaded pipes are connected with joints, and the non-threaded pipes are connected with tool joints by butt welding.
