Bangdong New Exported Pipe Fittings (Elbow , Tee)

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.

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.

Bangdong has exported several containers of pipe fittings , mainly butt weld elbow and equal tee , reducing tees.
