Buttweld is to connect pipes and fittings ends by a butt welding process. Also known by welded pipe fittings. It has ended in beveled or plain, dimensions normally from 3/4” to 24”. Manufactured according to ASME B16.9. In various materials like carbon, alloy, and stainless steel.
There are different parameters to be considered before purchasing and that is the size of the pipe fittings in diameter, thickness of the wall to be according to the pressure in the pipes, materials, shape and many others.
Types for Butt Weld Fittings
Ranges from usage and functions, butt weld fittings include elbow, tee, reducer, cap, and lap joint stub end.
Ranges from material types include carbon steel butt weld fittings, alloy, and stainless steel butt weld fittings.
Pipe elbow
The butt weld elbow is designed to change the direction of the fluid in the piping system. It has a long radius (LR) and a short radius (SR) type and has different degrees covers to 45 degrees, 90 degrees, and 180 degrees. Buttweld elbow is a steel elbow formed by hot pressing or forging. Its connection form is to directly weld the elbow and steel pipe. Butt-welded elbows are mainly used for elbow with higher pressure and temperature than other connection types (socket welded elbow or threaded pipe elbow).
Pipe bending
The pipe bending is used to change the direction of run of pipe. Pipe bend can be made of variety materials,like carbon steel,alloy steel,stainless steel,low temperature steel or high performance steel,etc.
It advantage is can matach long distance transition requirements,so it is commonly that bends dimension according to customer design.
Pipe tee
Apipe tee is also called triplet,three way and "T" pieces and it can be used to either combine or split a fluid flow. Most common are tees with the same inlet and outlet sizes, but 'reducing' tees are available as well.
Usually, the pipe tees have the same inlet and oulet sizes.
Pipe cross
Apipe tee is also called triplet,three way and "T" pieces and it can be used to either combine or split a fluid flow. Most common are tees with the same inlet and outlet sizes, but 'reducing' tees are available as well.
Usually, the pipe tees have the same inlet and oulet sizes.
End caps
End caps are usually used for protecting the end of pipe and other fittings, so the shape are designed according to the shape of pipe line.
End caps are widely well-known for the utmost output and outstanding results that it gives.
Size range:
- Out diameter: 1/2"-60" DN15-DN1500
- Wall Thickness: sch10-80s
- Pressure: SCH5 to SCH160v
- Max. wall thickness: 200mm
Pipe reducer
Pipe Reducers are the component in a pipeline that reduces the pipe size from a larger to a smaller bore (inner diameter).
Stub ends
Stub ends are buttweld fittings that can be used (in combination with a lap joint flange) alternatively to welding neck flanges to make flanged connections.
- Lap join stub end - available in a range of sizes to pair with stub end fittings for easy dismantling
- Stainless stub end such as Stainless Steel ASTM A403, 304L, 316L, 317
- Carbon steel stub end is tested and verified for durability, accuracy and precision
- Pipe collars are made from plates, with dimensions and tolerances in accordance with EN 1092-1 (Din 2642) or for lap joint flanges according to Asme B16.5.
Coupling Fittings
Pipe nipple is a length of straight pipe with male threads on both ends. It is one of the most popular category of pipe fittings.
It is a connector or a coupling threaded on both ends. Pipe nipples are used to allow plumbing to be connected to a water heater or other plumbing. They are used to fit straight end hose or pipe. A combination of pipe nipples are recommended for low-pressure discharge and suction service for various compatible liquids and not for compressible products like air, nitrogen or steam.
