BW Reducer Elbow ASME B16.9 Fittings

ASTM A234 WPB Butt Welded Fittings are the best selling products in Shanghai Zhucheng Pipe Fittings Manufacturing Co Ltd from China.We can also supply customers forged pipe fittings,pipes and some related products.

Whatis the difference between concentric and eccentric reducers?

Pipe Elbow is installed between two long pipes for changing the direction of the flow of liquid or fluid. These are commonly available in two types; 90 degrees and 45 degrees. Its function is to change the direction of the fluid by 90 degrees, so it is also called vertical elbow.

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.

45in BW reducer is belong to large dimension butt welded fittings,STD is a commonly used wall thickness for BW fittings.Other commonly used wall thicknesses for BW fittings are SCH 40,SCH 80.

180 deg elbow is not commonly used but indispensable pipe fitting.180 degree elbow can changes the pipe systems in 180 degree.Carbon and alloy steel pipe fittings always be chosen in many industries because of the great functions and reasonable price.

ASME B16.9 cross is a pipe fitting used to connect four pipes together, and the connection is achieved by welding. It plays a role in diversion or confluence in the pipeline system and is an important connector in the pipeline layout.

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.

Carbon steel elbow has two degrees:90 deg and 45 deg.In real application,90 deg is more used type.90 deg elbow can be long radius (LR) and short radius (SR) while 45 deg elbow only has long radius (LR).

A234 WP11 elbow is a pipe fitting used to change the direction of the pipeline. It is made of alloy steel. Its basic structure is a curved tubular part, usually with connection interfaces at both ends to connect with other pipeline components.

ASME B16.9 tee is a butt welded tee .ASME B16.9 is American Standard for BW fittings.Carbon steel fittings are always been chosen because of the great functions and affordable price.

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.ASME B16.9 is American Standard for butt welded fittings.

24in equal tee is belong to large dimension fittings.SCH 40 is a commonly used wall thickness for butt welded fittings.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.

Concentric reducer is used to join pipe sections or tube sections on the same axis The length dimension of the reducer is almost equal to the average of the big bore and smaller bore pipe diameters.

Carbon steel elbows are curved connecting pieces that join straight lengths of pipe, commonly at a 90° or 45° angle, allowing obstructions to be avoided in plumbing, ventilation, welding, and automotive applications.

Lap joint stub end is belong to butt welded fittings,lap joint stub end is not usually used in many time.Lap joint stub end always be used with lap joint flange.Stainless steel pipe fittings are popular because stainless steel’s excellent performance in corrosion resistance.

LR 90 degree steel pipe elbow are installed between different lengths pipe or tubing, It helps to change direction at 90 degree.

SR (short radius) elbow is only for 90 deg elbow.SCH XXS is the biggest wall thickness in butt welded fittings.The commonly used wall thicknesses:SCH 40 , SCH 80.The wall thickness more bigger,the bearded pressure of the fittings can be higher.

A234 WP22 elbow is a alloy steel pipe fitting used in piping systems.A234 WP22 is represents alloy steel butt welded fittings in American Standard.Elbows can manufactured as 45 and 90 deg.These elbows have similar functions,the only difference is 45 degree elbow can changes the direction of pipes in 45 degree while 90 degree elbow can changes in 90 deg.

BW 90 degree elbow is the most used elbow in all types of elbows.BW fittings are popular because it can achieve strong and permanent connection.Stainless pipe fittings are famous for the excellent anti-corrosive function.Shanghai Zhucheng can supply many kinds of pipe fittings made from stainless steel.

BW reducers have two types:Concentric Reducer and Eccentric Reducer.These two types can meet different demand.This is stainless steel BW COC reducer in the picture.Stainlee steel is better in corrosion resistance,so the used years will be longer than other matercial.

Steel pipe cap is usually welded onto end of pipe that blcok off the piping line system, it has same funtion with plug and blind flange. It is available in material of carbon steel, stainless steel and alloy steel.
