Forged Steel Fittings
ASME B16.11 Forged Steel Fittings are made by the round steel or ingot by forging which including socket weld fittings and threaded fittings.
It covers 45 Degree Elbow, 90 Degree Elbow, Equal Tee, Reducing Tee, Cross Tee, Full Coupling, Half Coupling, Pipe Cap, Socket Weld Union and Swage Nipple.

Material: Carbon Steel, Alloy Steel, Stainless Steel, Duplex Steel.
Steel Pipe Cap
Socket Weld Cap and Threaded Cap
Connection: Butt Weld Cap, Socket Weld Cap and Threaded Cap .
Function: Seal pipeline end.
Material: Carbon Steel, Alloy Steel, Stainless Steel, Duplex Steel.
Steel Pipe Plug
Threaded Plug
Plug is used at the end of the pipe to prevent leakage.
Types: Hex Head Plug, Square Head Plug, Round Head Plug.
Material: Carbon Steel, Alloy Steel, Stainless Steel, Duplex Steel.
Forged Steel Unions
Socket Weld Union and Threaded Union
Type: Concentric Swaged Nipple and Eccentric Swaged Nipple.
Material: Carbon Steel, Alloy Steel, Stainless Steel, Duplex Steel
Threaded Bushing
Hex Head Bushing
They usually made of hexagonal rod after cutting and forging. It is convenient to strengthen and tighten because hex head shape,
Pipe Nipple
Swaged Nipple
Usually used in the connection of different diameter pipeline.
Type: Concentric Swaged Nipple and Eccentric Swaged Nipple.
Material: Carbon Steel, Alloy Steel, Stainless Steel, Duplex Steel
Forged Steel Outlet Fittings
Sockolet, Weldolet and Threadolet
It is a reinforced pipe fitting for branch connection, can replace the use of reducing tee, reinforcement plate. The advantages of Pipe Olets are safety and reliable, low cost, simple construction, fixed parameters and easy to design and use. It is increasingly widespread used in pipes with high pressure, high temperature, large diameter, thick wall, and replaces traditional branch connection way.
Threaded Short Nipple
Forged threaded pipe fittings adopts NPT (taper pipe thread) used for British pipe only, not metric pipe.
ASME B16.11 Forged Steel Fittings Dimensions
Specification
DN6, DN8, DN10, DN15, DN20, DN25, DN32, DN40, DN50, DN65, DN80, DN100. And customer specifications usually between DN15 to DN50.
Pressure
The pressure rating are 3000LB/SCH80, 6000LB/SCH160, 9000LB/XXS, and threaded elbow pressure rating are 2000LB, 3000LB and 6000LB.
Application
ASME B16.11 Forged Steel Fittings are commonly serves in the areas of petrochemical, pharmaceutical, power, aerospace, military, fire fighting, metallurgy, shipbuilding, gas, nuclear power, and environmental protection which require high pressure bearing capacity and precise size.
NPT & BSP Threaded Fittings
1) ISO7/1 is the international common thread seal pipe thread, thread angle is 55o, conicity is 1:16. Internal thread has Rp and Rc two types, while external only has cone-shape R. Besides, Rp-R is more active compares with Rc-R .
2)ISO228 is the international general non – thread seal pipe thread (British Standard Pipe Thread), thread angle is 55o, internal and external thread are both Rp.
3)ANSI B1.20.1 is American thread seal pipe thread, thread angle is 60o (NPT), conicity is 1:16. Both internal and external thread are Rc. It frequently serves in high temperature and high pressure pipeline.
AMSE B16 11 forged fittings use NPT more often. Though thread angle is different, NPT and ISO7/1 (BSP) can connect with each other in the diameter of 1/2 and 3/4 because of their same thread pitch.
