BW elbow 90/45/180 deg ASTM A234 WPB/C

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.

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

BW 90 elbow is the most used degree,there is also 45 deg elbow to choose.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 is American Standard of butt welded fittings.

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″.

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.

SS 304/304L elbow is stainless steel pipe fitting.304/604L is the most commonly used grade of stainless steel in American Standard.Elbows can made as 90 deg and 45 deg.Among these,90 degree elbows can be LR and SR while 45 degree elbows only have LR type.

Pipe tees can be equal tee and reducing tee.These tees have same functions,the only difference is the reducing tee can reduce the flow in the piping system.Stainless steel fittings are popular because of the an-ti corrosive function.Stainless steel pipe fittings can used over 50 years.

Carbon Steel Pipe Fittings Elbow is a most common type of CS fitting used to join pipe or tubing to allow a change of direction, usually a 90° or 45° angle, Elbows ends may be machined for butt welding , threaded , or socketed

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.

The function of butt weld elbow is to change direction or flow in a piping system. There are the 45°, 90° and 180° .
According to the material, it can be divided into carbon steel, alloy steel and stainless-steel.
According to its radius of curvature, there are long radius  and short radius butt weld elbow.

SSAW steel pipe in the production process, we need to pay attention to a series of matters. Except for the following test items, according to the API standard and other relevant standards and the special requirements of some users, but also the need for steel, steel pipe and other tests Destructive tests, including physical and chemical properties of the raw materials into the plant sampling, visual inspection of 100% steel .

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.

Whatis the difference between concentric and eccentric reducers?

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.

BW 3D elbow is belong to Butt welded (BW) elbows.3D means the radius is 3 times of dimensions long.A234 WPB is the most used grade of carbon steel butt welded (BW) fittings according to American Standrad.The degree of the butt welded 3D elbow can be 45 deg, 90 deg and 180 deg.

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.

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.

Elbow is a commonly used connecting pipe fitting in plumbing installation, which is used for connecting pipe bends

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.

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.

Concentric reducers are tapered and are used when the diameter between pipes changes. It can be axially shifted and externally reconfigured to offer more efficient reducer connection.

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

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.

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 BW reducer is one type of butt welded fittings.BW reducers can be concentric (COC) reducer and eccentric (ECC) reducer.These reducers have same functions,the only difference is the internal structure.
