Carbon steel A234 WPB 90degree elbow

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.

ASME B16.9 BW tee is a butt welded pipe fitting according to American Standard.Carbon steel fittings are used in many applications because of its great excellent functions.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’s dimnesions and its usage and advantage

A234 WPB elbow is the most chosen carbon steel elbow in all the types of elbows.A234 WPB is carbon steel grade for butt welded fittings;BW elbows have LR (long radius）and SR (short radius).Elbows have 90deg and 48deg to change the direction of the pipe system.

304/316L BW tees are the most used tees in stainless steel tees.304/316L are the most used grades in American Standard.Tees can be Equal Tees and Reducing Tees.You could find the summary “Equal VS Reducing Tee” in the content below.Stainless steel pipe fittings are populat because of the excellent functions of corrosion resistance.

45 deg elbow has three types:BW,SW,THD.Among these,The commonly used elbows can be 45 deg and 90 deg.BW (butt welded) 90 degree elbows have LR (long radius) and SR (short radius) while 45 degree elbows only have LR type.

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. Such fittings are important because they meet two needs, that is, to connect or separate liquid streams. They are widely used in positive and vacuum applications.

90 deg short radius elbow is a special type only for BW 90 degree elbows.Stainless steel pipe fittings are popular because of the an-ti corrosive function.Stainless steel pipe fittings can used over 50 years.

It helps to change direction at 90 degree, and is commonly used to connect hoses to pumps, deck drains and valve.SR 90 degree elbow is the same as the pipe elbow mentioned above, but the diameter is shorter. Therefore, this kind of steel elbow is often used when space is not enough.A 90 degree elbow attaches readily to plastic, copper, cast iron, steel and lead. It can also attach to rubber with stainless steel clamps. Available in many materials like silicon, rubber compounds, galvanized steel etc.

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.

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. 

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 have beveled ends to allow for ease of welding. This bevel allows for full penetration weld in most of the cases. Butt welded elbows are mainly used for elbow with higher pressure and temperature.

What is a 90 DEGREE LR ELBOW and what about its specification and advantages.

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.

Stainless 316L tee is a stainless steel pipe fitting used to change the direction of the fluids or gas and branch the pipe system.Tees can be equal tees and reducing tees for different usages.Stainless steel fittings are be chosen by the long using years.Beacuse of the high corrosion resistance,stainless steel can be used over 50 years.

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.

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.

These Stainless Steel Pipe Fittings are best known for their heat resistance, creep strength and tensile strength. Machined and fabricated to meet your diverse piping requirements, these pipes fittings exhibit excellent corrosion resistance in a wide range of atmospheric environments.

ASTM A403 Stainless Steel Butt Weld 45 Degree Elbow refers to the material of forged and rolled austenitic stainless fittings for pressure pipes. Common grades are WP304/L, WP316/L. They can be used into many fields as engineering industry, energy conversion plants etc. ASTM A403 WP304, WP316 Elbow are buttweld fittings made for austenitic stainless steel applications with forged material.

The pipes cannot appreciate because of what the external arrangement of the pipe reducer seems but the flow of the pipe is changed by the internal width conical transition arrangement. 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.

Difference between a pipe elbow and a pipe bend is as follows:

Long Radius (LR) Elbow is also called LR elbow – means the radius is 1.5 times the pipe diameter
L/R 45°Elbow: Long radius 45 degree elbow changes the direction by 45 degrees.
L/R 90°Elbow: Long radius 90 degree elbow changes the direction by 90 degrees.
L/R 180°Elbow: Long Radius 180 degree return bend allows complete reversal of flow.

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.

There are 45 ° elbows and 90 ° elbows in common use. Those with a bending radius of about 1.0 times the outer diameter of the pipe are called short radius elbows; The long radius elbow is about 1.5 times the outer diameter of the pipe

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.
