ASME B16.9 Butt Weld Eccentric Reducer

SS400 90 DEG elbow is used to transport flow in piping system.Butt welded fittings used welded connection to connect with the pipes to achieve the strong and premanent connection.

A234 WPB BW tee is a commonly used pipe fitting to transport flow in piping system.There are two tpyes of tees:Equal Tee and Reducing Tee.SCH 80 is a commonly used wall thickness for butt welded fittings,the other commonly used wall thickness is SCH 40.

The connection methods of elbow and pipe include: direct welding (the most common method), flange connection, hot melt connection, electric fusion connection, thread connection and socket connection

Elows’ standard and its wall thickness

Concentric reducers are beneficial to use where different ratings and to wear protection is required in conveying between flanges or pipes. nd the pipe is connected through conical transition section on the same axis.

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.

BW tees and elbows are both commonly used pipe fittings used to transport flow in piping system.Stainless steel pipe fittings re popular because of the an-ti corrosive function.Stainless steel pipe fittings can used over 50 years.

Concentric reducers will change kindly between the pump and piping， A pipe reducer is available in various specifications, such as a single diameter change and also in a multiple diameter change.

Whatis the difference between concentric and eccentric reducers?

Elbow could be ranged from direction angle, connection types, length and radius, material types. As we know, according to fluid direction of the pipelines, elbow can be divided into different degrees, such as 45 degree, 90 degree,180 degree, which are most common degrees. Also there has 60 degree and 120 degree, for some special pipelines.

45° Pipe Elbow is also known as “45 bends or 45 ells”. The 45° pipe elbow is used to connect tubes at a 45° pipe angle. As the name suggests, this is a pipe fitting device which is bent in such a way to produce 45° change in the direction of flow of the fluid/gas in the pipe.

Connect two pipes with the same or different nominal diameters to make the pipeline turn at 90 degrees, 45 degrees, 180 degrees and other angles

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.

90 deg elbow is the most chosen degree in elbows.There are also 45 deg and 180 deg elbows.Elbows can be Equal Elbow and Reducing Elbow to satisfy different demands.ASTM A234 WPB is a material grade in American Standard repersents carbon steel butt welded fittings.

Steel pipe tee has three types: BW (butt welded),SW (socket welded),THD (threaded).The branches can be equal and reducing.Shanghai Zhucheng is a superior pipe fittings supplier who provide high quality pipe fittings and forged flanges in years.

Elbow is a fitting device which is bent in such a way to produce 90 degree change in the direction of flow of the content in the pipe.

What is a Concentric Reducer,what about its specification and advantages.

Long radius elbow refers to the pipe outer diameter with radius of curvature equal to 1.5 times, i.e R = 1.5D.
Short radius elbow means that its radius of curvature is equal to the outer diameter of the tube, i.e R = 1.0D

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.

A equal tee’s usage,dimension and features.

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.

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.

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″.

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.

Branches of tees have two types:Equal tee and Reducing tee.These two types tees have same functions,but reducing tee has one more function:it can reduce the flow of the gas or fluids.Butt welded fittings are the most used fittings in many applications because the size range of the BW fittings is big.

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

BW elbows are belong to butt welded fittings,wall thickness of BW fittings decided the pressure that the fittings can resistance.Wall thickness SCH 40 is a commonly used wall thickness in butt welded fittings.
