Butt Welded 90° Elbows ASTM A234 WPB Pipe Fittings

The two ends of concentric reducer are designed with large diameter and small diameter, and the pipe is connected through conical transition section on the same axis.

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.

BW carbon tee are popular because carbon steel has great functions and cheap price.Coated pipe fittings also used in piping systems as the coating can enhance the functions for normal carbon steel.Galvanized coating is the most used coating,it can enhance the anti-resistance function.

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″.

Elbow is divided into carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon, PPC, etc. Its function is to change the direction of the fluid by 90 degrees, so it is also called vertical elbow.

BW (butt welded) reducer have two types:Eccentric Reducer and Cocentric Reducer.Reducer only has welded connection.However,swage nipple which belong to forged fittings has same function to reducer.

A 90 degree elbow attaches readily to plastic, copper, cast iron, steel and lead. It can also attach to rubber with stainless steel clamps. Elbow connectors can link pipes to avoid water leakage and air leakage between pipes.

BW ELBOW are installed between different lengths pipe or tubing. Its function is to change the direction of the fluid by 90 degrees, so it is also called vertical elbow.

12 IN Carbon Steel Elbow is an important pipe fitting in piping system as it can change the direction of the pipes in 90 degree.ASTM A234 WPB is a commonly used grade for carbon steel in American Standard.

Butt welded lateral tee is a special type of BW tees.It is different from the normal tees as the lateral tee can change the direction of the pipe system in 45 degree.Carbon steel fittings are the most used fittings as carbon steel material has great functions and affordable price.

The stub end is usually a short section of pipe fittings, with one end being a flap structure, and the other end can be a stub end or special processing according to specific needs. The turning part is designed to facilitate the connection with other pipe fittings or equipment.

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.

Elows’ standard and its wall thickness

45 degree BW tee’s specification and advantages in pipe system.

Butt welded cap is a pipe fitting used to closed the piping systems.BW caps use welding connection to connect with the pipes.SCH 80 is a commonly used wall thickness of BW fittings,the other commonly used wall thickness is SCH 40.

Steel pipe bend is a butt welded fitting to transport fluids or gas.The degree of steel bend will be customize according to the client’s demend.Pipe bend and elbow have some similarity,you could find the summary “pipe bend VS elbow” below.

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.

What is Galvanizing?

Galvanizing, or galvanization, is a manufacturing process where a coating of zinc is applied to steel or iron to offer protection and prevent rusting. There are several galvanizing processes available, but the most commonly offered and used method is called hot-dip galvanizing.

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.

Compared to 90 degree elbow, 45 degree elbow produces less friction, and with the lower pressure. 45 degree elbow is widely used in chemical industry, food, water supply facilities, electronic industry, chemical pipeline, horticulture, agricultural production, solar equipment pipeline, air conditioning pipeline and other fields.

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. 

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.

Concentric reducer’s dimnesions and its usage and advantage

Equal BW tee is a commonly used fittings in butt welded fittings.ASTM A234 WPB WPC are both grades for carbon steel 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 (COC) reducer is one type of BW reducer.The other type of reducer is Eccentric (ECC) Reducer.The different of COC Reducer and ECC Reducer is the internal structure.BW pipe fittings are popular because of the strong and permanent connection.

BW 90 degree elbow is the most chosen type in all types of elbows.It can be long radius (LR) or short radius (SR).ASTM A234 WPC is standard for carbon steel butt welded fittings.There is also a more commonly used standard for carbon steel butt welded fittings is ASTM A234 WPB.
