ASTM B16.11 Forged Fittings Diemntions – Threaded & Socket Weld

ASTM B16.11 Forged Fittings Dimensions, Forged Threaded and Socket Weld Fittings in the size range 1/2” to 4” and in pressure ratings Class

ASTM B16.11 is the international standard used in the manufacturing of Forged Fittings which include two types that are Forged Threaded Fittings and Forged Socket Weld Fittings. These High-Pressure Fittings are available in Various Materials like Stainless Steel, Carbon Steel, High Nickel Allys, and more.

 

It is produced in the Size range of 1/2” to 4”, and in pressure ratings Class 2000, 3000, 6000, and 9000. Pressure rating classes also differ in Threaded and Socket Weld Fittings, Class 2000, 3000, and 6000 for threaded fittings and Class 3000, 6000, and 9000 for socket-weld fittings.

Forged pipe fittings are manufactured by forging and machining solid steel and are available in various shapes like Elbow, Bushing, Cap, Cross, Coupling, Plug, Tee, End Cap, Union, Reducer, Reducer Insert, Boss, Nipple, Adapter, Outlet. It is used for associating or connecting pipes, pumps, valves, & other equipment to create a piping system below the size 2 or 4 inches in diameter.

 

Socket weld fittings connect to pipes by fillet welds and threaded fittings by screwing pipe onto the fittings. Normally Class 3000 fittings are used for pipes in schedule 80/XS; Class 6000 for pipes Sch. 160; Class 9000 fittings for pipes with larger wall thickness (XXS).

Creative Piping Solutions Pvt. Ltd. is one of the top manufacturers of High Pressure Forged Pipe Fittings in India. We are authorized Suppliers and Exporters of Threaded and Socket Weld Fittings in South Africa, Malaysia, Singapore, Qatar, Italy, Philippines, Australia, and Dubai, UAE.

ASME B16.11 Standard Scope:

This standard contains dimensions, pressure-temperature ratings, markings, tolerances, and material requirements for forged fittings. Custom-design forged fittings with special dimensions, threads, or counterbores may be made by agreement between the manufacturer and purchaser. All dimensions tables are given below.
