ASTM Q235 Carbon Steel CONCENTRIC REDUCER BW B 16.9

There are two types of 90 deg elbows:LR (long radius),SR (short radius).45 deg eblows are also have wide applications,be attention,45 deg elbow only have LR type.Butt welded pipe fittings have the most large used range as it can be 1/2″ – 80″.

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.

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

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.

Fittings that change direction in a piping system are called elbows which available in 90 degree and 45 degree long radius elbow. Both of them has the center line at 1.5 x NPS from elbow end.

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.

Steel pipe tee has three branches that can change fluid direction. It has T-shaped or Y-shaped, and include Equal Tee and Reducing Tee (Reducer Tee). Steel tee is widely used in pipe networks for convey liquids and gases.

90 deg SR (short radius) elbow is a type of BW elbows,90 degree elbow also has LR (long radius) type.Shanghai Zhucheng has expericenced pipe fittings factory which can provide high quality pipe fittings and forged flanges.

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.

According to fluid flow direction of the pipes, elbows can be divided into different degrees, such as 45 degree, 90 degree, 180 degree, which are most common elbows. Also there are 60 degree and 120 degree elbows for some special pipelines. This degree is just an representation of the angle by which the fluid flow is going to change after flowing through the said elbow.

Stainless elbow is a popular used type of elbow becase the stainless steel has excellent an-ti corrosive function.Shanghai Zhucheng is an excellent butt welded fittings factory who supplys high quality pipe fittings and flanges for years.

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.

A234 WPB/WPC BW 90 degree elbows are carbon steel butt welded fittings.Elbows also have 45 degree.These elbows have similar functions,the only difference is the 90 degree elbow can changes the direction in 90 deg while the 45 degree elbow can changes in 45deg.

Carbon steel tee is a commonly used tpye of tees.This is butt welded (BW) carbon steel tee in the picture.it can welded with pipes to achieve permanent connection.Equal tee only can change the direction of the pipes while reducing tee can also reduce the flow of the fluids or gas.

What is a pipe bend,what about its specification and its difference between a elbow

Large Diameter Concentric Reducer is belong to butt welded fittings because BW fittings size range is 1/2″-80″ while the forged fittings only have 1/8″-4″.ASTM A234 WPB is represents to carbon steel pipe fittings in American Standard.

BW (butt welded) reducer can be concentric (COC) reducer and eccentric (EEC) reducer.Among these two types,concentric reducer is more commonly used.The materical of reducer can be carbon steel,alloy steel and stainless steel.Clients can choose different material as their demands.

45 degree elbows have same functions to 90 degree elbows,the only different is 45 deg elbow changes the direction of pipes in 45 deg while the 90 deg elbow changes the direction in 90 deg.BW pipe fittings are popular as its strong and permanent connection.

A concentric reducer is used to join pipe sections or tube sections on the same axis. The concentric reducer is cone-shaped, and is used when there is a shift in diameter between pipes. For example, when a 1″ pipe transitions into a 3/4″ pipe and the top or bottom of the pipe doesn’t need to remain level.

Butt weld elbow is a steel elbow formed by hot pressing or forging. Its connection form is to directly weld the elbow and steel pipe. Butt welded elbows are mainly used for elbow with higher pressure and temperature than other connection types. According to the valve body material, it has stainless steel, carbon steel and alloy steel elbow

Elows’ standard and its wall thickness

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.

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.

It can be axially shifted and externally reconfigured to offer more efficient reducer connection. Concentric reducers facilitate the delivery of mud and abrasive fluids and are suitable for corrosive operations and where different ratings and wear protection are required between flanges.
