ASTM A403 Material is a standard developed by the American Society for Testing and Materials (ASTM), mainly for forged austenitic stainless steel pipe fittings. This standard specifies in detail the requirements for the manufacturing, size, tolerance, material quality, etc. of pipe fittings, and plays an important role in regulating the production, inspection and use of stainless steel pipe fittings.

The carbon content of UNS S32750 duplex stainless steel pipe shall not exceed 0.03%, manganese shall not exceed 1.20%, nickel shall be between 6.0% and 8.0%, chromium shall be between 24.00% and 26.00%, molybdenum shall be between 3.00% and 5.00%, and nitrogen shall be between 0.24% and 0.32%.Materials equivalent to UNS S32750 include ASTM A790 UNS S32750, Super Duplex 2507, and 1.4410.

SMO 254 stainless steel pipe is a high-performance stainless steel material.It has unique chemical composition and excellent performance, maintaining excellent stability and durability.SMO 254 stainless steel material can be processed through various methods to produce steel pipes, fittings, flanges. The corresponding American and European stainless steel pipe grades for SMO 254 are UNS S31254/EN 1.4547/6Mo.

The EN10216 standard mainly includes materials such as P195, P235, P265, P195GH, P235GH, P265GH, 13CrMo4-5, 10CrMo9-10, etc. The size range of EN10216 carbon steel seamless pipe according to different standards and application requirements. Its outer diameter can range from 10.2mm to 711mm, the wall thickness can range from 1.6mm to 100mm.

ASTM A182 alloy steel forged flange vary in size and types.According to American standards ASME B16.5 and ASME B16.47,the size range from 1/2"to 60".The types include weld neck,slip on, threaded, socket weld,blind and lap joint flanges.

ASTM A105 threaded fittings are forged fittings made of carbon steel material, generally produced according to the American standard ASME B16.11 or the British standard BS3799 production standard. Carbon steel threaded fittings include various types such as threaded elbows, tees, cross, couplings, nipples, pipe plugs, bushings, caps, and unions etc. ASTM A105 carbon steel pipe fittings are widely used in various pipeline systems due to their superior performance and low cost.
