ASTM A182 F304 threaded half nipples, are nipples with one end thread and the other end weld. The other shape of nipples are threaded full nipples,which are both ends with thread.Pipe nipples also have sock weld connection,they are similar to threaded nipples,the only difference is threaded nipples use thread,while SW nipples use socket welded.

Pipe Tee is a most frequently used pipe fitting or connector nowadays. It functions the same as olets that means it is used to take a branch connection for linear pipeline. As the name TEE represents, the shape is T-shaped with two outlets, at 90° to the connection to the main line

Shanghai Zhucheng is well known manufacturer of MSS SP-83 Union, consists of three parts: a nut, a female end and a male end. Our offered Threaded Pipe Union similar to a coupling, allows the convenient future disconnection of pipes for maintenance or fixture replacement. Threaded Reducing Union makes easy connection and disconnection, multiple times whenever we need.

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.

According to its radius of curvature, there are long radius elbow and short radius elbow. Long radius elbow refers to its radius of curvature is equal to 1.5 times the outside diameter of the pipe, that is, R=1.5D; A short radius elbow means that its radius of curvature is equal to the outer diameter of the pipe, that is, R= 1.0d.(D is the diameter of the elbow, and R is the radius of curvature).

The specification of ASTM A182 Forged Pipe Fittings includes forged fittings, stainless steel, rolled alloy, forged alloy, pipe flanges as well as high-temperature service. Later then forgings and hot working, it would be cooled down to a certain temperature before heat treatment.
The Alloy Steel A182 Threaded Elbow material grade contains ASTM A182 F11 / 12 / 5 / 9 / 91 / 92 / 22.

Stainless steel 90 deg threaded elbow is popular because it is easy to install or replace.ASME B16.11 forged fittings are pipe fittings according to American Standard.There are many types fot customers to choose:NPT PT BSPP BSPT PF.

Bending radius less than or equal to 1.5 times of pipe diameter belongs to elbow, and bending radius greater than 1.5 times of pipe diameter belongs to elbow

Stainless steel threaded pipe fittings are very popular forged fitttings because of the excellent anti-corrosion function.ASME B16.11 forged pipe fittings are SW pipe fittings and THD fittings.There are threaded pipe fittings in the picture.SHANGHAI ZHUCHENG PIPE FITTINGS MANUFACTURING CO LTD is an excellent pipe fittings and flanges supplier from China.

The equal cross is one kind of the pipe cross,  the equal cross means all the 4 ends of the cross are in same diameter.
The reducing cross also is called unequal pipe cross , it is the pipe cross which the four branch ends are not in the same diameters.

In small diameter pipes (below DN50), reducing nipples are also often used to replace reducing joints for pipe reducing. Reducing nipples also have concentric and eccentric parts

CL3000 threaded couplings are the most used pressure of couplings,there are still CL2000 and CL6000 to choose.ASTM A105 forged pipe fittings are usually be chosen because of the affordable price and great functions.

A combination of pipe nipples are recommended for low-pressure discharge and suction service for various compatible liquids and not for compressible products like air, nitrogen or steam. 

ASTM A182 F316 threaded full couplings are pipe fittings with two threaded ends.ASME B16.11 forged fittings have THD fittings and SW fittings,THD fittings have CL2000,CL3000,CL6000 to choose;SW fittings have CL3000,CL6000,CL9000 to choose.

In general, carbon steel pipe fittings and flanges are widely used for applications which do not require materials with higher resistance to corrosion such as stainless steel and alloy steel. Carbon Steel Fittings is primarily used across piping systems for its hardness, moderate to good tensile strength and inexpensiveness.

The main purpose of using pipe caps is to waterproof the connections. They are also used to close the the ends of hydraulic or pneumatic pipes and tubes. The use of Forged End Pipe Caps is common in many industries such as oil and gas industries, chemical industries and water supply lines.

Concentric BW reducer is a tpye of reducers,there is also eccentric reducer to choose.BW reducers used to reduce the flow of the fluids in the piping system.Stainless steel pipe fittings are popular because the superior functions.SCH 40 and SCH 80 are the commonly used wall thicknesses in butt welded fittings.

Threaded elbow used thread connection to connect with the pipes.Pipe elbows have three types:THD (threaded),SW (socket weld),BW (butt welded).These elbows used different connections to connect with the pipes in piping system.Class 3000 forged fittings are the most used high pressure fittings.

Threadolet has the same basic design as a weldolet. However the main difference is the fitting has a female threaded connection to link to the branch connection. This makes a 90° branch and comes in full size or reducing for a straight piece of pipe

BS3799 F304 Threaded Pipe Fittings are named by its manufacturing forging process and produced according to ASME B16.11, MSS-SP-79\83\95\97 and BS3799 standards.

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.

90° Steel Pipe Elbow is the most commonly used elbow type in pipe system with the function to change the direction of fluid in 90 degree. It connects pipes with same or different diameter.

ASTM A106 SCH160 threaded nipples are carbon steel pipe fittings that have widely used range.There are two shapes for choose:TOE(threaded one end) and TBE (Threaded both ends).

We are manufacturer of High Pressure Pipe Fittings from China. Threaded fittings are available in pressure ratings 2000LB, 3000LB, and 6000LB; Threaded Coupling Dimension is 1/8″ –  4″ / DN6 – DN100.

Class 3000 hex head plugs are used in the end of piping systems or equipments to achieve close function.ASTM A182 F304 forged pipe fittings are the most common used stainless steel pipe fittings because of the reasonable price and superior functions.Threaded plugs have 3000lb and 6000lb pressures for customers to choose.
