ANSI B16.9 Pipe Fittings Butt Weld Concentric Reducers

Carbon steel tee is a commonly used tpye of tees.This is butt welded (BW) carbon steel tee in the picture.it can welded with pipes to achieve permanent connection.Equal tee only can change the direction of the pipes while reducing tee can also reduce the flow of the fluids or gas.

ASME B16.9 elbow means BW elbow.ASME B16.9 is an American Standard for Butt welded fittings,A234 WP22 is represnets BW Alloy pipe fittings. Elbows can be 90 deg and 45 deg to change the pipes in 90 degree or 45 degree.Sometimes the elbows can be 180 deg to satisfy the clinet’s demands.

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.

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.

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’s dimnesions and its usage and advantage

Equal diameter tee, also known as straight tee, the branch diameter of the tee is the same as the pipe diameter of the tee. The three branches of tee have same diameters.

Carbon steel butt weld reducer is belong to ASME B16.9 pipe fittings,there are concentric reducer and eccentric reducer for chosen to meet different demands.

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.

SR (short radius) elbow is only for 90 deg elbow.SCH XXS is the biggest wall thickness in butt welded fittings.The commonly used wall thicknesses:SCH 40 , SCH 80.The wall thickness more bigger,the bearded pressure of the fittings can be higher.

Pipe tees have two types: Equal Tee and Reducing Tee.These tees have similar functions but reducing tee have one more function,reducing tees can reduce the flow in the pipe system.Shanghai Zhucheng is an excellent pipe fittings manufacturer who supplys high quality fittings and flanges for years.

SS 304/316 pipe tees are popular because these tees have excellent corrosion resistance.Tees can made for three types:BW (butt welded) tee,SW (socket weld) tee,THD (threaded) tee.Clients can choose different type of tees to satisfy different demands.ASME B 16.9 is represents butt welded fittings in American Standard.SW fittings and THD fittings are belong to forged fittings which marked as ASME B 16.11.

Tee welding joints are formed when two pieces intersect at a 90° angle. This results in the edges coming together in the center of a plate or component in a ‘T’ shape. Tee joints are considered to be a type of fillet weld, and they can also be formed when a tube or pipe is welded onto a base plate.

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.

BW reducer can be concentric (COC) reducer and eccentric (ECC) reducer.The main difference is the internal structure.COC and ECC types reducers could meet different demands in many applications.You could find the summary “COC VS ECC” in the content below.

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.

BW tees and reducers are the most used pipe fittings in the piping system.Tees can branch the flow in piping systems.Carbon steel pipe fittings are popular as the great functions and affordable functions.

A pipe tee isuaually used in different industries,petroleum, natural gas, chemical, water and electricity, building and boiler industries.What’s the advantage ,how to choose a suitable tee ?

ASME B16.9 BW 90 elbow is pipe fitting manufactured according to American Standard.ASME B16.9 is American Standard of butt welded fittings.There is BW elbow in the picture,you could find the specification and dimensions below.

When short radius elbows are used, the maximum working pressure should not exceed 0.8 times of long radius elbows of the same specification Miter elbows are usually used for large-size pipes with moderate conditions in low pressure (design pressure s2.0mpa), water and similar fluid media

45 deg BW elbow can change the direction of fluids or gas by 45 deg,it only has LR (long radius) type while 90 deg butt welded elbow has both LR and SR(short radius) types.Carbon steel is the most used material in pipe fittings because it has great functions to satisfy many applications.

24IN carbon steel BW elbows are large dimension fittings,ASME B16.9 is represents butt welded fittings in American Standard.Carbon steel fittings are used in many applications because of its great excellent functions.

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.

Concentric reducers provide an in-line conical transition between pressurized pipes of different diameters. It is cone-shaped, and is used when there is a shift in diameter between pipes. 

Large Diameter Concentric Reducer is belong to butt welded fittings because BW fittings size range is 1/2″-80″ while the forged fittings only have 1/8″-4″.ASTM A234 WPB is represents to carbon steel pipe fittings in American Standard.

ASME B16.9 Stainless Steel Butt Weld Cross Fittings The function of a cross is similar to that of a tee by means of the exception of providing two 90 Deg outlets opposite each other.

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

These types of tube fittings like male elbows and female elbows have been specifically designed for use on instrumentation, process and control systems and equipment employed in chemical, petroleum, fluid power, electronic and pulp and paper plants.
