Threaded alloy steel fittings are mainly used for small pipe diameters (Small Bore Piping), generally for piping systems whose nominal diameter is NPS 2 or smaller. Threaded pipe fittings are available in three pressure ratings: Class 2000, 3000 and 6000.
Thread pipe fittings can provide an effective seal for pipes transporting liquids, gases, steam, and hydraulic fluid. Threaded pipe fittings are mainly used in sectors and fields such as petrochemical, medical and health, electric power, aerospace, military, fire, metallurgy, shipbuilding, gas, nuclear power, and environmental protection, which are subject to high pressure and precision.
- The material for forged threaded alloy steel fittings conforms to the requirements of ASTM/ASME A182/SA182 F5, F9, F11, F22 and F91.
- The dimensions for forged alloy steel threaded fittings conform to ASME B16.11
- Products are packaged to ensure that there is no damage during transit.
- In case of exports,standard export packaging is done in wooden cases.
- All fittings and flanges are marked with Grade,Lot No,Size,Degree and our trade mark.
- On special requests we can also, make custom marking on our products.
