DN40 Stainless Steel Coupling Threaded Pipe Fittings

Pipe Swage Nipple (also known as reducing nipple) is divided into tubing sub and casing sub. Flanging nipple in pipe connection is commonly used with flange.

The use of Forged End Pipe Caps is common in many industries such as oil and gas industries, chemical industries and water supply lines.

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).

Steel pipe elbow can be divided into 3 types as buttweld, threaded, socket weld in accordance with connection.Threaded elbow is more convenient compare with the buttweld and socket weld elbow.

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.

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.

High pressure Stainless Steel A182 Threaded Tee is used for providing branch, it can be divided into equal tee and reducing tee. The common used dimension is DN15, DN20,DN25 and DN40 for socket weld tee and threaded tee.

Threadolet considered to a threaded fitting, and it is manufactured in 3000 and 6000 classes. t typically is in the size range of 1/2″ to 2” and is welded over a hole either drilled or burned in the pipe.

ASTM A182 F316 pipe nipples have two shapes:TOE (threaded one end) and TBE (threaded both ends).The nipples in the picture are all in TOE shape.The pressures can be chosen:CL2000,CL3000,CL6000.

Carbon steel pipe fittings are used in many applications because of its great excellent functions.Carbon steel pipe fittings can manufactured as THD (threaded) fittings,SW (socket weld) fittings and (BW) butt welded fittings.The specifications are in the content below.

What is a treaded nipple,what about its specification and its difference between coupling.

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.

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.

Threaded elbow and coupling are used thread type to connect the pipes to trsnsport flow in piping system.THD fittings are belong to forged fittings,ASME B16.11 fittings are American Standard for forged fittings.

Swage Nipple and short joint reducing joint are pipe fittings used for straight-line connection of two pipes with different sizes to realize pipe diameter reduction. There are concentric reducing joint and eccentric reducing joint

Double threaded Swage Nipplet:Swage Nipple with external threads at both ends. The screw plug is used to plug the external thread pipe fittings at the end of the pipe, including square head pipe plug, hexagonal pipe plug, etc.

Concentric swage nipple is mainly used for vertical pipeline. eccentric swage nipple is mainly used in horizontal pipelines.

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.

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

What is a plug,what about its specification and its difference between a caps.

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.

A234 WPB threaded coupling mainly consists of a main body and thread structures at both ends. The main body is usually cylindrical, and its length varies according to different specifications and usage requirements.
