BW 90 Degree Elbow Steel Pipe Elbow Specifications

Concentric Reducer (COC Reducer),is one type of BW reducer.The other type is Eccentric Reducer (ECC Reducer).The two types reducers can meet different demands,You could find the “Concentric VS Eccentric” below to learn the usages for these two types reducers.

DN900 LR elbow is large dimension fitting,for the large dimension,the elbows always be butt welded.Wall thickness STD is a commonly used thickness of BW fittings,the other commonly used wall thickness are SCH 40, SCH 80.

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

Reducing tee is a commonly used fittings to branch the pipes and reduce the flow in the piping systems.Large dimension is for butt welded fittings.ASME B16.9 pipe fittings are BW fittings according to American Standard,the size range for the ASME B16.9 fittings is 1/2″-80″.

Concentric reducer in a pipe system, its making process and its difference between a eccentric reducer.

90 degree steel pipe elbow functioned to change fluid direction by 90 degree, so also named as vertical elbow. It is the common degree in all the pipeline systems and used most in all different degree of elbows

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.

5in SW elbow is used to socketed with pipes and then welded on pipes.ASME B16.11 pipe fittings mean forged pipe fittings.Forged pipe fittings can be divided in socket weld fittings and threaded fittings.

Butt weld fittings are manufacture by seamless or welded pipe. For pipe fittings manufacturers, the forming process of welded pipe and seamless pipe is basically same. Butt welded fittings can be divided into carbon steel butt welded fittings and stainless-steel butt-welded fittings

ASME B 16.9 lateral tee is one special type of BW tees.It has similar functions to the normal tee,the only difference is the lareral tee can change the direction in 45 degree while the normal one changes in 90 degree.

Steel pipe tee has two types:Equal Tee and Reducing Tee.Common tees have 90 dergee between the main pipe and the branch.There also has lateral tee which has 45 degree between the main pipe and the branch.

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.

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.

45 deg elbow has three types:BW (butt welded) elbow,SW (socket welded) elbow and THD (threaded) elbow.Elbows can also be 90 degree and 180 degree to meet different demands.Shanghai Zhucheng is an experienced pipe fittings manufacturer who supplys high quality pipe fittings and flanges for many years.

Carbon BW tee is wide used in many applications because welded connection can provide permanent connection.Schedule XS is wall thickness of this tee in the picture.In addition,the commonly used wall thicknesses:SCH40, SCH80.

Elbows and seamless elbows are often used in the bending parts of pipes to change the direction of pipes Its function is to change the direction of the fluid by 90 degrees, so it is also called vertical elbow.

The long radius is used most commonly, and it is also the default radius. When it is the place with the high pressure or the high flow rate, the long radius elbow is usually used. If the resistance requirements of the solid transmission pipeline are strict, the larger radius elbows will be used.

The reducing tee has two outlets cut at 90 degrees with the main pipe, and the size of the branch pipe is smaller than the port of the pipeline. It is used for main pipe string accessories, solvent welding accessories, side outlet and conflicting soluble welding accessories

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.

BW elbow is popular because of the strong and permanent connection.The anti corrosion function of carbon steel and alloy steel is not as good as stainless steel,so coated pipes and fittings have paint or oil to protect the fittings during sea transportion.

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.

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. 

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.

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.

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.

A420 WPL6 tee is a pipe fitting with three ports, mainly used to divide a pipe into two branches or merge two branches into one pipe. Common ones are equal diameter tees and reducing tees. In the layout of the pipeline system, the structure of the tee can flexibly change the flow direction of the fluid to achieve the function of branching or merging.

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.
