Stainless Steel ASTM A182 Threaded Coupling Dimensions

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.

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.

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

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

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).

 NPT A105 bushing is mainly used to connect two pipes of different diameters in the pipeline system or to correct the error in the pipeline installation. It is usually made of A105 carbon steel, has high strength and good corrosion resistance, and can withstand high working pressure.

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.

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.

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

Forged 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. It is a connector in between nominal bore pipes. Their material can be made of carbon steel A105 and stainless steel SS316 & 304.

A swage nipple is something similar to that of a reducer but it is used to join the butt welded pipe with a socket welded or screwed pipe.Like the reducer,swage nipple is also available with two variations:concentric swage nipple and eccentric swage nipple.The swage nipple generally adopts the MSS SP-95 or the BS3799 Standard.

B16.11 threaded fittings can be furnished in product forms of Elbow, Cross, Tee, Coupling, Half Coupling, Boss, Cap, plug and bushing.Threaded fittings are available in pressure ratings Class 2000, 3000, and 6000;

We are the manufacturer of High Pressure Steel Pipe Fittings for China. Pipe Coupling contains Socked Coupling and Threaded Coupling.

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.

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).

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).

Thread Types:

NPT  PT  BSPP  BSPT  PF

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.

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.

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.

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.

MSS SP-97 Threadolethas the outstanding advantages of safety and reliability, cost reduction, simple construction, improved medium flow channel, series standardization, and convenient design and selection

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.

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.

Swage nipple is a common accessory in industrial pipeline connection. Common threaded short joints are divided into double head external thread, single head external thread, flat head external thread, and short joints connected by flanges.
