ASME B16.9 BW Tee Carbon Steel Fittings

usage,specification of a equal tee and ite difference between a reducing tee.

Steel pipe bend two pipes into a certain angle and connects them together to change the direction of the pipe. it could be bend directly from a finished pipe with cold bending processes, to different degrees.

Butt weld fittings would also be referred to as welded pipe fittings. When these would be used in stainless steel and carbon steel, they would be able to offer certain advantages as compared to socket weld and threaded fittings. Whereas socket weld would only be available up to a specific size, you would find butt weld fittings to be available in sizes starting 1/2 inch to 72 inch.

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.

This kind of elbow is classified by angle, and 45 degree elbow and 180 elbow is also very popular. And steel pipe elbow is also available in 60 degree, 30 degree and other special angle according to practical needs.

Classify,specification of a BW 90 degree elbow

Steel pipe elbow is a key part in a pressure piping system used to change the fluid flow direction. It is used to connect two pipes with same or different nominal diameters, and to make the pipe and thus the fluid direction turn to a certain direction of 45 degree or 90 degree. This change in fluid flow direction adds pressure losses to the system due to impact, friction and re-acceleration.

BW elbows have the most wide used range in all types of elbows.Shanghai Zhucheng is an excellent supplier for pipe fittings,all the fittings made from carbon steel and alloy steel will have anti-rust paint,and stainless steel fittings will have anti-rust oil to protect the fittings in the sea transportation.

Carbon steel tee is the most used type in all tees because carbon steel has great functions and affordable price.Galvanized pipe fittings has better anti-corrosive function than normal carbon steel pipe fittings,galvanized fittings have similar functions as stainless steel fittings,but the price is cheaper than stainless steel fittings.

Welded steel pipes are popular because of the strong and permanent connection,the ends of the pipes can welded with flanges.Slip on (SO) flange can slip on the pipe,and then welded on the pipes.

BW 90 degree elbow is the most commonly used type of elbows.There is also 45 deg elbow.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.You could find the steel pipe elbow specifications in the connent below.

0 degree elbow, also called “90 bends or 90 elbows”, are manufactured as SR (Short Radius) elbows and LR (Long Radius) elbows.

A234 WPB Carbon Steel Buttweld 90 Deg Elbow’s usage

Stainless steel BW tees are always used in many corrosive environments because of the corrosion resistance of stainless steel.ASTM A182 F316 is a commonly used grade for stainless steel.Stainless steel pipe fittings are popular because of the an-ti corrosive function.Stainless steel pipe fittings can used over 50 years.

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.

ASME B 16.9 tee is BW (butt welded) tee belong to butt welded fittings.These tees can bu equal type or reducing type.Normal tees can change the direction of the pipe system of 90 deg.And tees also have lateral tees to change the direction of 45 deg.

The butt welded eccentric reducer is a pipe fitting used to connect pipes of different diameters, and its central axes do not overlap, and there is an eccentricity.

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.

Radius of Long Radius (LR) Elbows is 1.5 times the pipe diameter. Radius of Carbon Steel Short Radius Elbow is 1.0 times the pipe diameter. Carbon Steel Seamless Elbow are in demand for use between two lengths of pipe or tube allowing a change of direction, usually these elbows distinguished by connection ends.

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 .

Concentric reducers will change kindly between the pump and piping， Concentric reducers are used to connect pipe segments or pipe segments on the same axis.

Steel pipe elbows have seamless and welded version, normally in 90 degree, 45 degree & 180 degree. Material are carbon steel, alloy steel & stainless steel. BW 90 degree elbow is formed by hot forming and connects steel pipes or other pipe fittings through butt welding process

Long radius elbow refers to the pipe outer diameter with radius of curvature equal to 1.5 times, i.e R = 1.5D. Its function is to change the direction of the fluid by 90 degrees, so it is also called vertical elbow.

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. A pipe reducer is available in various specifications, such as a single diameter change and also in a multiple diameter change.

Elows’ standard and its wall thickness

45 degree elbow is second common use after 90 degree elbow. The function of a 45 degree elbow is the same as a 90 degree elbow, but the measurement of dimensions is different to that of the 90 degree elbow.

DN1200 BW elbow is belong to large dimension fittings,these fittings always be butt welded fittings because of the large size.Butt welded fittings used welded type to connect with the pipes to achieve strong and permanent connection.
