Butt weld Pipe Fitting more details please check below :

Butt weld fittings is one of the most popular connection type in pipeline systems. It always been required in large quantities in different industries, and especially for the large diameter pipelines.

What is Butt Weld Fittings

Butt weld is to connect pipes or fittings ends by welding. It`s a weldable Steel Pipe fitting that would allow to branch off, allow for change of direction of flow, attach auxiliary equipment, or reduce the size of the pipe.

In the case of forged Steel Butt Weld Fittings, you would find them to be manufactured according to ANSI/ASME B16.9.

Also known by Welded Pipe fittings

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 102 inch.

Like general category of pipe fittings, Butt Weld Pipe Fittings includes:
Butt weld Elbow in 45 degree or 90 degree or other degree required by clients
Butt weld Tee and Reducing Tee , Reducer, Cap, Cross , Lateral Tee , Barred Tee , Y tee etc. 

Butt weld Elbow

Butt weld elbow is to change fluid direction in pipeline systems, it has long radius (LR) and short radius (SR) types, and has different degree covers 45 degree, 90 degree and 180 degree. So there are:
LR 45 degree butt weld elbow: 45 degree elbow that with long radius (1.5 x Diameter), and change fluid direction by 45 degree.
LR 90 degree elbow
SR 45 degree elbow: Short radius (1 x Diameter) elbow in 45 degree, change direction.
SR 90 degree elbow

LR 30 degree elbow

SR 30 degree elbow

More than 90 degree elbow we will call it as steel bend. Like LR/SR 180 degree bend.

Butt weld elbow dimensions could be specified as diameter (in NPS) and thickness according to ANSI, samples as LR 90 degree elbow 4 inch and thickness in schedule 40 or schedule 80.

Butt weld Tee

Butt weld tee ( Equal Tee ) has a 90 degree branch along with a straight pipe, it will provide a connects for to install an additional equipment to a pipeline. With the tee structural, same sides of the ends could be welded to the pipe, 90 branch was left open for weld another pipe or a device.

Butt weld Reducing Tee

Same structural of the equal tee, but the 90 degree branch has a smaller size than the straight pipe diameter. So it is used to install a equipment or a pipe with smaller size.

Butt weld Reducer

It has Concentric Reducer and eccentric reducer two types, used for adjust the fluid rate and speed, by welded a large diameter pipe on one end and a smaller diameter pipe on the other end.

Common material types of butt weld fittings

Same with socket weld fittings, you would now be able to find butt weld fittings to be available as butt weld elbow, tee, out lets (olets), reducers, and caps. In fact, these would be some of the most common type of butt weld fitting and would be specified according to schedule of pipe and nominal pipe fittings.

Body material

It includes different body materials of alloy, stainless and carbon steel butt weld fittings. Therefore, it usually uses welded or Seamless Pipe as the starting material. Could be manufactured by forging, with the help of multiple processes, in order to get the shape of tees and elbows, amongst the other things.

Stainless steel butt weld fittings usually in thin thickness

Just like you would find normal pipe to be sold from Schedule 10 to Schedule 160, you would find the case to be same for butt weld fitting as well. In stainless steel, butt weld fittings have been found to be more common. This would be thanks to the cost advantage that it has to offer. Schedule 10 fittings would also be more common in stainless steel fittings.

Carbon steel butt weld fittings

Carbon steel butt weld fittings includes body material in  ASTM A234 WPB  (most commonly) and WPC, MSS-SP-75 WPHY . And thickness usually at schedule 40 steel pipe fittings , STD, or 80, where pressure class ranged with 1500 psi, 2500 psi, 3000 psi, 6000 psi and 9000 psi.

Alloy steel butt weld fittings

Alloy steel butt weld material usually in ASTM A234 WP1, WP5, WP9, WP11, WP22, WP91 etc.

Classified by dimensions

Butt weld pipe fittings dimensions referred to the pipe dimensions standard ANSI B36.10 and B36.19.
Diameter range: 1", 2", 3", 4", 6", 8" and up to 36".
Thickness range: Schedule 10, schedule 40, schedule 80, XS, XXS and SCH 160

Where fitting dimensions of butt weld fittings are concerned, this would consist diameter in NPS and thickness in schedule.

Concentric reducer, eccentric reducers, long radius elbow, tees. The primary reason why these fittings would be used in construction projects is because they would play an important part in branching off, changing the direction of flow, or even mechanically joining equipment to the system. With the help of specified pipe schedule, butt weld fittings would be sold in nominal pipe sizes.

How a butt weld fitting is made

This kind of pipe fitting would be made by a process known as hot forming. This would include bending the pipe and then forming it in to a shape. The starting material of this fitting would be a pipe that would first be cut in to length. This would then be heated and molded in to specific shapes with the help pf dies. In addition, heat treatment would also be done in order to get the desired mechanical properties and removed residual stresses.

Benefits of butt weld fittings

• The welded connection would help to get more robust connection
• Continuous structure of metal would add to the strength of the piping system
• When butt weld fittings would be matched with the appropriate pipe schedules, they would help to offer a seamless flow inside the pipe
• It provides the option of various turn radius by using Long Radius, Short Radius, or 3R elbows
• Found to be cost effective compared to the socket weld or threaded counterparts
• These fittings would be available in Schedule 10, thus allowing for a thinner wall option
• These fittings have been found to be more common in the configuration of Schedule 10 and Schedule 40.
