ASME B16.11 Forged Pipe Fittings NPT Thread Union
Forged pipe fitting ASME B16.11 standard
ASME B16.11 is the standard contains ratings, dimensions, tolerances, marking and material requirements for forged fittings, both socket-welding and threaded. Threaded fittings are available in pressure ratings Class 2000, 3000, and 6000;
Socket welding fittings are available in pressure ratings Class 3000, 6000, and 9000.
Generally, both fittings size range is 1/8″- 4″or DN6-DN100.
There are various types of ASME B16.11 socket-welding fittings, such as Elbow, Cross, Tee, Coupling, Half Coupling, Boss, Cap, Union and Sockolet; while ASME B16.11 threaded fittings can be furnished in product forms of Elbow, Cross, Tee, Coupling, Half Coupling, Boss, Cap, plug and bushing.
Threaded pipe fittings provide permanent welded connections for pipes. Threaded joints probably represent the oldest method of joining piping systems. Same as Socket Weld fittings, threaded fittings are mainly used for small pipe diameters (Small Bore Piping); generally, for piping whose nominal diameter is NPS 2 or smaller.
They are available in three pressure ratings: 2000lbs, 3000lbs and 6000lbs.
NPT Thread
The American National Pipe Thread Tapered, is the best known and most widely used connection where the pipe thread provides both the mechanical joint and the hydraulic seal. NPT has a tapered male and female thread which seals with Teflon tape or jointing compound. Dimensions of American Taper Pipe Thread, with Sealant Compound.
The threaded pipe union is similar to the coupling and can be flexibly disassembled when it needs to be repaired or replaced. The reducing threaded union is easy to disconnect and link, and can be operated multiple times.Threaded union is used to connect two pipes and the ends will be machined to NPT or BSP that match external end threads of pipe.The threaded pipe union is similar to the coupling and can be flexibly disassembled when it needs to be repaired or replaced. The large demand material is carbon steel A105 and stainless steel 304 & 316. We manufacture forged steel union according to MSS SP-83.
