Butt Welded Reducer BW Fittings Specifications

45 deg BW elbow can change the direction of fluids or gas by 45 deg,it only has LR (long radius) type while 90 deg butt welded elbow has both LR and SR(short radius) types.Carbon steel is the most used material in pipe fittings because it has great functions to satisfy many applications.

ASME B16.9 elbow means BW elbow.ASME B16.9 is an American Standard for Butt welded fittings,A234 WP22 is represnets BW Alloy pipe fittings. Elbows can be 90 deg and 45 deg to change the pipes in 90 degree or 45 degree.Sometimes the elbows can be 180 deg to satisfy the clinet’s demands.

Pipe tees can be two types:Reducing Tee and Equal Tee.Both types of tees can branch the pipes in the piping systems.Schedule 40 is a wall thickness of the butt welded fittings,the commonly used schedules are SCH 40,SCH 80.

Steel pipe bend is belong to butt welded fittings.The bend radius R should greater than or equal to 3 times of the outside diameter.Bends could manufacture as the customize degree to meet the client’s demends.

BW 90 degree elbow is formed by hot forming and connects steel pipes or other pipe fittings through butt welding process. Its function is to change the direction of the fluid by 90 degrees, so it is also called vertical elbow.

45 degree elbow is second common use after 90 degree elbow. The function of a 45 degree elbow is the same as a 90 degree elbow, but the measurement of dimensions is different to that of the 90 degree elbow.

LR 90 degree steel pipe elbow are installed between different lengths pipe or tubing. It helps to change direction at 90 degree, and is commonly used to connect hoses to pumps, deck drains and valve.

BW equal tee is always used in piping system to branch the pipes.ASME B16.9 Pipe Fittings are butt welded fittings in American Standard.Pipe tees can be equal tee and reducing tee.These tees have same functions,the only difference is reducing tee can reduce the flow in piping system.

Large diameter equal tee is belong to butt welded fittings because BW fittings size range is 1/2″-80″ while the forged fittings only have 1/8″-4″.Carbon steel fittings are used in many applications because of its great excellent functions.

90 degree elbow, also called “90 bends or 90 elbows”, are manufactured as SR (Short Radius) elbows and LR (Long Radius) elbows.

Branches of tees have two types:Equal tee and Reducing tee.These two types tees have same functions,but reducing tee has one more function:it can reduce the flow of the gas or fluids.Butt welded fittings are the most used fittings in many applications because the size range of the BW fittings is big.

In the layout of the pipeline system, long radius elbows should generally be used for connection, and short radius elbows are usually used in places where the installation position of the pipeline system is compact or to reduce costs

Steel pipe elbow is a key part in a pressure piping system used to change the fluid flow direction. It is used to connect two pipes with same or different nominal diameters, and to make the pipe and thus the fluid direction turn to a certain direction of 45 degree or 90 degree. This change in fluid flow direction adds pressure losses to the system due to impact, friction and re-acceleration.

Concentric reducer is used to join pipe sections or tube sections on the same axis. It is cone-shaped, and is used when there is a shift in diameter between pipes. 

SS400 90 DEG elbow is used to transport flow in piping system.Butt welded fittings used welded connection to connect with the pipes to achieve the strong and premanent connection.

BW reducers can be concentric (COC) reducer and eccentric (ECC) reducer.These reducers have same functions,the only difference is the internal structure.Stainless pipe fittings are popular because of the an-ti corrosive function.Stainless steel pipe fittings can used over 50 years.

A403 WP304  eccentric reducer is a pipe fitting used to connect pipes of different diameters, and the central axes do not overlap, which means there is an eccentricity. The eccentric reducer has two ends, one with a larger diameter and the other with a smaller diameter.

Reducing tee is a commonly used fittings to branch the pipes and reduce the flow in the piping systems.Large dimension is for butt welded fittings.ASME B16.9 pipe fittings are BW fittings according to American Standard,the size range for the ASME B16.9 fittings is 1/2″-80″.

When short radius elbows are used, the maximum working pressure should not exceed 0.8 times of long radius elbows of the same specification Miter elbows are usually used for large-size pipes with moderate conditions in low pressure (design pressure s2.0mpa), water and similar fluid media

It can have concentric reducer and eccentric reducer. It is widely used in pipeline installation projects, such as when the diameter of the pipeline needs to be changed at the inlet and outlet of the pump

Long radius elbow refers to the pipe outer diameter with radius of curvature equal to 1.5 times, i.e R = 1.5D. Most elbows are available in short radius or long radius variants. When the two ends differ in size, the fitting is called a reducing elbow or reducer elbow.

Equal butt weld elbow is used to change the direction of the flow in piping system.SCH 80 is a commonly used wall thickness for butt welded fittings,the other commonly used wall thickness is SCH 40.

S31254 Elbow is a pipe fitting used in pipeline systems, and its main function is to change the flow direction of the fluid in the pipeline. Common bending angles are 45°, 90° and 180°, etc.

Stainless concentric reducer is belong to BW (butt welded) fittings.Reducer can be two types:Concentric (COC) Reducer and Eccentric (ECC) Reducer.The main difference of these two typws are the internal structure.Stainless steel pipe fittings have better functions than other material pipe fittings.

BW cap is used to close the pipe system,the function is similar to plug.A234 WPB is a commonly used grade for carbon steel in American Standard.SCH 40S is represents a wall thickness of butt welded fittings.The commonly used wall thicknesses for BW fittings are SCH 40,SCH 80.

BW elbows have the most wide used range in all types of elbows.Shanghai Zhucheng is an excellent supplier for pipe fittings,all the fittings made from carbon steel and alloy steel will have anti-rust paint,and stainless steel fittings will have anti-rust oil to protect the fittings in the sea transportation.

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

Reducing tee is a kind of pipe fitting whose branch size is smaller than the size of pipeline parts. It is used for main pipe string accessories, solvent welding accessories, side outlet and conflicting soluble welding accessories.
