Threaded Coupling Forged Steel Fittings

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).

Full Coupling: Both ends of the full thread coupling are threaded. Half Coupling: One end of a half thread coupling is threaded and the other end is welded.

The overall shape of the A105N hex head plug is a combination of a hexagonal head and a plug body. The hexagonal head design is convenient for operation with tools such as wrenches, and can provide better torque transmission, so that the tube plug can be tightened or loosened.

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.

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.

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).

Threaded coupling is used to connect two pipes with threaded connection.Forged steel pipe fittings can divided into SW (socket weld) fittings and THD (threaded) fittings.

They have applications in many industries,including chemical processing, petroleum, refining, marine waste treatment, utilities / power generation, industrial equipment, natural gas compression and distribution industries. Tee pipe is also recommended for industrial equipment hydrodynamic system

Threaded union is easy to install and disassemble so that it is popular in piping system.Threaded fitting used thread type to connect with pipes,threaded fittings have many pressures:2000,3000,6000.

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

TOE means threaded at one end when translated. Thus, we can say that a nipple TOE is a nipple that has one threaded end.
In this case, we have the acronym TBE for “threaded both ends” which means threaded at both ends. In other words, this is the most typical type of nipple as described above for connecting two parts or fittings with female threading.

ASTM A182 F304 Threaded Union is a specialized piping component designed for quick and secure disconnection and reconnection of pipes. This union features female National Pipe Taper (NPT) threads on both ends, facilitating seamless integration with male-threaded pipe sections. It is primarily used to simplify the installation, maintenance, and inspection processes in complex piping systems.

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.

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

These Stainless Steel Pipe Fittings 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.

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

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.

ASTM A182 F316 is a popular grade for stainless steel in American Standard.Stainless steel fittings are popular because of the an-ti corrosive function.Stainless steel pipe fittings can used over 50 years.

Equal tees are available in sizes from half an inch to 48 inches (or larger) and in seamless and welded execution (seamless up to 24 inches, welded for tee sizes above 24 inches).

Especially in high-pressure, high-temperature, large-diameter and thick walled pipes, it is increasingly used, replacing the traditional branch connection method.

Swaging nipple (also known as reducing nipple) is a forged pipe fitting. It is used to change the diameter of the pipe and connect two pipes of different sizes.

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.
