DN40 Stainless Steel Coupling Threaded Pipe Fittings

Steel pipe elbow can be divided into 3 types as buttweld, threaded, socket weld in accordance with connection. The material specification are ASTM A234, A182, A403, A105, A694, A350, A420 and A860.

Reducing pipe (reducing nipple) is a pipe fitting used for straight-line connection of two pipes with different sizes to realize pipe diameter reduction. There are concentric reducing joints and eccentric reducing joints

Threaded nipple is a short piece length of pipe or tube. Its size is specified according to the length of this section of pipe and the diameter. It can be with threaded or flat ends. And both ends can be the same or different.
There are two shape : threaded one end (TOE) and threaded both end ( TBE).

hat is a threaded tee,what about its specification and its difference between a elbow.

Swage Nipple are similar to reducers, but they’re smaller, and they’re used to link larger screwed, or socket welded pipes to smaller screwed or socket welded pipes. They come in concentric and eccentric varieties, just like reducers. Swages come in a variety of end

Steel tee is a T-shaped pipe fitting with three branch pipes. It is used to divide pipes to adjust flow and change direction.

Used for all sorts of media: chemical substances, petrochemical products, liquefied gas – especially in loading/unloading applications. There are also couplings intended for highly aggressive chemical substances, lined with ECTFE – a polymer resistant to chemicals.

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

The basic difference between couplings and unions in use is that couplings connect pipes to pipes or pipes to bends.Unions are used to connect and disassemble part of the piping system for maintenance or replacement.

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.

Threadolet considered to a threaded fitting, and it is manufactured in 3000 and 6000 classes.

High Pressure Steel Pipe Fittings contain buttwelding pipe fittings, socked weld fittings and threaded pipe fittings. Threaded Steel Coupling is a short piece with screw in NPT or BSP ends or one end, which is available in stainless steel, alloy steel and carbon steel. The size range is DN6-DN100. There are various grade of A694 Threaded Coupling, Such as A694 F42 / 46 / 52 / 56 / 65 / 70

This makes a 90° branch and comes in full size or reducing for a straight piece of pipe

3000LB threaded couplings have the most widely using range.ASTM A105 forged fittings is carbon steel fittings belong to American Standard.Threaded couplings have two types:Half and Full.The other pressures could be chosen:#2000,#6000.

What is a Threaded Coupling,what about its specification and its advantages.

The branch pipe stand is also called branch pipe seat, saddle and saddle type pipe joint. Reinforced pipe fittings mainly used for branch pipe connection, instead of branch pipe connection such as reducing tee, reinforcing plate and reinforced pipe section

Hex Head Bushing: A hex bushing is a threaded fitting with a hex head used to tighten the fitting into a threaded opening. Flush Bushing: Flush bushing are used in piping systems. They are installed in the pipe to reduce the size of the pipe. Forged bushing is ideal for use with water and oil in chemical, petrochemical, pulp, paper, shipbuilding, waste incineration, and semiconductor industry applications.

Threaded couplings used thread connection to connect two pipes.Threaded coupling is belong to forged steel fittings.The other type of forged fitting is socket weld fittings.All the forged fittings are high pressure pipe fittings.

We are the ISO certified manufacturer who produce and export ASME B16.9 and ASME B16.11 Steel Pipe Fittings. Threaded Steel Coupling is a short piece with screw in NPT or BSP ends or one end, which is available in stainless steel, alloy steel and carbon steel. The size range is DN6-DN100.

These Stainless Steel A182 Threaded Union are best known for their heat resistance, creep strength and tensile strength. Machined and fabricated to meet your diverse piping requirements, these pipes fittings exhibit excellent corrosion resistance in a wide range of atmospheric environments.

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.

The coupling is used to make connection of two pipes. The maiterial is available in stainless steel, alloy steel and carbon steel. The size range is DN6-DN100.
