Buttweld Fittings are a category of pipe fittings used to connect sections of pipes and change their direction, branch them off, or alter their size. These fittings are characterized by their smooth, beveled ends, which are welded to the pipes in a process known as butt-welding. This welding technique forms a strong, leak-proof connection and provides better mechanical strength in comparison to other types of fittings.

Buttweld Fittings Types We Specialize In

Buttweld Elbow

Buttweld Elbow

A Buttweld Elbow is a pipe fitting used to change the direction of flow in a piping system, typically at angles of 45° or 90°,180°.

Buttweld Tee

Buttweld Tee

A Buttweld Tee is a T-shaped pipe fitting used to branch off or combine the flow in a piping system, with one inlet and two outlets. It is available in equal and reducing configurations to pipe diameters.

Buttweld Reducer

Buttweld Reducer

A Buttweld Reducer is a pipe fitting that connects pipes of different diameters to regulate flow, available in concentric and eccentric types.

Buttweld Cross

Buttweld Cross

A Buttweld Cross is a pipe fitting with four openings used to connect or split flow in four directions, commonly found in process piping systems.

Buttweld Stub End

Buttweld Stub End

A Buttweld Stub End is a short pipe fitting with a flared end, used in conjunction with a lap joint flange for easy assembly and disassembly in piping systems.

Lap Joint Stub End

Lap Joint Stub End

A Lap Joint Stub End is a short fitting with a flared end used with lap joint flanges, allowing easy alignment and disassembly in piping systems.

Buttweld End Cap

Buttweld End Cap

A Buttweld End Cap is a pipe fitting used to seal the end of a pipe, providing a closure for the pipeline while maintaining structural integrity.

Buttweld Pipe Bends

Buttweld Pipe Bends

Buttweld Pipe Bends are pipe fittings used to change the direction of flow in a piping system, available in various angles and radii to suit different applications.
