ASME B16.11 2 inch Steel Pipe Fittings Coupling Size Chart

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.

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

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.

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.

Shapes:

Concentric: Concentric swage nipple is mainly used for vertical pipeline.

Eccentric: eccentric swage nipple is mainly used in horizontal pipelines.

Threaded elbow can reduce pipeline stress and pressure drop reduce pipeline stress, reduce pipeline pressure drop, and reduce pulsating power of fluid to pipeline.

Swaging nipples is divided into tubing sub and casing sub. Flanging nipple in pipe connection is commonly used with flange. Diameter pipe (reducing nipple) is a pipe fitting used for straight connection of two pipes with different sizes to realize pipe diameter reduction. There are concentric reducing joints and eccentric reducing joints

What is a threaded elbow,what about its specification and its advantages.

Forged Olets Pipe Fitting is generally made of integral forging. The structure of the weldolet is divided into main pipe connection end, reinforcement part and branch pipe connection end.

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).

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 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.

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.

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

The length of the threaded nipple is usually determined by the total length of the thread. 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.

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.

Stainless steel pipe fittings including Tee,Cross, Elbow, Reducer, Coupling, Nipple, Plug & Cap,Union.They can be connected with pipes by welding, socket and thread.

Threaded couplings could be divide into full coupling (both ends threaded) and half coupling(one end threaded,the other end welded).Forged pipe fittings dimensions are all in small size,1/8″-4″.

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

Concentric swage nipple is mainly used for vertical pipeline. t is used to change the diameter of the pipe and connect two pipes of different sizes.

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.
