Buttwelding Fittings

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.

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.

BW 90 deg elbow is the most used type of elbows in many industries.Schedule 80 is represents the wall thickness of the butt welded fittings.It is a commonly used wall thickness.another wall thickness is SCH 40.

45 degree elbows have same functions to 90 degree elbows,the only different is 45 deg elbow changes the direction of pipes in 45 deg while the 90 deg elbow changes the direction in 90 deg.BW pipe fittings are popular as its strong and permanent connection.

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.

BW elbow can welded with pipes to achieve strong and permanent connection.ASTM A234 WPB pipe fittings are the most popular carbon steel fittings.There is also has A234 WPC for carbon steel fittings.

A234 WPB BW reducer has the most wide ragnge of applications in all types of butt welded reducer, because A234 WPB is the most used grade in carbon steel.Carbon steel pipe fittings are accepted in many projects because these fittings have great functions and reasonable price.

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 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.

BW (butt welded) reducer have two types:Eccentric Reducer and Cocentric Reducer.Reducer only has welded connection.However,swage nipple which belong to forged fittings has same function to reducer.

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.

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.

BW elbow types have BW (butt welded),SW (socket weld),THD (threaded).The butt welded elbow is the most used type.Elbows have two shapes:Equal and Reducing.Shanghai Zhucheng is a pipe fittings manufacturer who can supply 45 deg,90 deg and 180 deg elbows.

Carbon steel elbows are the most commonly used elbows in all the types and material elbows.Large dimensions elbow is butt welded fitting,you can find the butt welded fittings specification below.

BW 90 degree elbow is usually be carbon steel for large dimensions.Butt welded 90 deg elbow also can be alloy steel and stainless steel.Steel pipe fittings are used in piping systems in many industries.

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.

Butt Weld Concertric Reducer is the type of pipe fitting which helps to join two pipes with different diameters. There are various material for The pipe reducers as per the demands of industries and also available in many dimensions.

The lap joint stub end is required when attach the lap-joint flange to the piping system. The stub end and lap-joint flange assembly are used mainly in piping systems that necessitate frequent dismantling for inspection or routine maintenance.

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.

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.

There are two types of 90 deg elbows:LR (long radius),SR (short radius).45 deg eblows are also have wide applications,be attention,45 deg elbow only have LR type.Butt welded pipe fittings have the most large used range as it can be 1/2″ – 80″.

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.

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.

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.

According to its radius of curvature, there are long radius elbow and short radius elbow. Long radius elbow refers to its radius of curvature is equal to 1.5 times the outside diameter of the pipe, that is, R=1.5D; A short radius elbow means that its radius of curvature is equal to the outer diameter of the pipe, that is, R= 1.0d.(D is the diameter of the elbow, and R is the radius of curvature).

An equal tee, otherwise called straight tee, means the branch diameter of this tee is same with the main pipe (Run pipe) diameter of this tee.
A pipe tee is defined “equal” when the bore size at the run and branch sides have the same diameter. An equal tee is, therefore, used to connect two pipes of the same nominal diameter.

SS 316L elbow has better corrosion resistance than other material elbows.Butt welded fittings will use welded connection to connect with pipes,so these fittings have great anti leakage function.SS316L elbows always be chosen because of its excellent functions so that it can be used in many years.

Elbow is a pipe fitting that changes the direction of piping. According to the Angle, there are 45° and 90°180° three most commonly used. Elbow material can be divided into carbon steel, alloy steel and stainless-steel.
