Buttweld Concentric Reducer Buttweld Pipe Fittings

Specificationo and usage of a 90degree BW elbow.

Elbow is a commonly used connecting pipe fitting in plumbing installation, which is used for connecting pipe bends

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

Steel pipe bend is belong to butt welded fittings,bends have some similar usages as elbows.However,bends can be customized by clients to satisfy different demands.API 5L B is a grade of carbon steel material for pipes and bends.

Concentric reducers are tapered and are used when the diameter between pipes changes. It can be axially shifted and externally reconfigured to offer more efficient reducer connection.

What is a pipe Tee,its specification and importance.

Concentric reducer’s dimnesions and its usage and advantage

24IN carbon steel BW elbows are large dimension fittings,ASME B16.9 is represents butt welded fittings in American Standard.Carbon steel fittings are used in many applications because of its great excellent functions.

BW elbows are belong to butt welded fittings,wall thickness of BW fittings decided the pressure that the fittings can resistance.Wall thickness SCH 40 is a commonly used wall thickness in butt welded fittings.

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.

Steel pipe elbow is a key parts in a piping system for to change the fluid flow direction. It is used to connect two pipes with same or different nominal diameters, and to make the pipe turn to a certain direction of 45 degree or 90 degree.

Steel Reducing Tee: The branch diameter is smaller than the main line diameter. Tee reducer is usually described as NPS diameters in 4”x 4”x 3”, 4”is the main line pipe diameter, and 3”is the reducing branch

Concentric reducers are perfectly suitable to use in the exclusion of the pump. It is cone-shaped, and is used when there is a shift in diameter between pipes. A pipe reducer is available in various specifications, such as a single diameter change and also in a multiple diameter change.

Large Size 90 Degree Elbow have an improtant use in piping system to transport flow.Carbon steel elbow is the most used material because of the great functions and affordable price.

Reducer can divided as concentric reducer and eccentric reducer.These reducer have same functions in pipe system,the only diffierence is the internal structure. Carbon steel fittings are used in many applications because of its great excellent functions.

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.

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.

Steel bend is almost same as pipe elbow. It’s radius is bigger and extensive used in oil and gas, engineering and construction industry.

It is used to handle any high or low weight fluid flow through the tee.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.

The function of an end cap is to block off the end of a line a piping system, This is achieved by placing the end cap over the open line and welding around the point.

Butt welded tee can be equal type and reducing type.Both types can change the direction of the piping system in 90 deg.In addition,the reducing tees can reduce the flow of the fluids or gas.Shanghai Zhucheng is an excellent pipe fittings manufacturer from China who supply high quality fittings for years.

What is the use of Weldolet?

Butt Weld Fittings include elbows, tees, cross, caps and reduces. These fittings are the most common type of welded pipe fitting and are specified by nominal pipe size and pipe schedule. Buttweld fittings are manufacture by seamless or welded pipe and are formed to get the shape of elbows, tees and cross etc.

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

ASTM A234 specification has many grades, such as WPB, WPC, WP5, WP9 WP11, WP12, WP22, WP91 and so on.
In these standard Grade WPB is the most common material used for medium and high temperature pipelines. W means weldable, P means pressure, B is grade b, refer to the minimum yield strength.

Concentric reducers provide an in-line conical transition between pressurized pipes of different diameters. It is used to connect pipe segments or pipe segments on the same axis.

Carbon steel butt welded 90° elbows are belong to ASTM A234 WPB pipe fittingsBW 90 deg elbows could be made in two types:LR (Long Radius) and SR (Short Radius).The angle of pipe elbows are 45deg and 90 deg.Only 90 deg elbows have LR.
