Butt Weld Elbows
A butt-weld elbow is a carbon steel elbow made with the same outside diameter and wall thickness as the pipe, changing the direction of a steel pipeline by butt welding.
It is used to turn pipe routes in heating, steam, fire and process lines. It is supplied in 90° and 180° types from 21.3 mm to 273 mm, welded and seamless, in standard wall, SCH40 and SCH80.
Main Applications
- Changes of direction in heating and hot water lines
- Steam and condensate lines
- Fire protection mains
- Boiler room manifold connections
- Process and cooling water lines
- Coils and return lines with 180° elbows

Which material? On a black steel pipeline the elbow is chosen with the same outside diameter and wall thickness as the pipe; stainless butt-weld elbows are used for corrosive media.
Advantages
Same Size as the Pipe
- Outside diameter and wall match the pipe
Seamless Option
- For high-pressure and steam lines
Wide Size Range
- From 21.3 mm to 273 mm
180° Elbow
- One piece for coils and returns
Construction and Design Features
- Weld ends suited to butt welding with the pipe
- Welded or seamless body
- Standard, SCH40 and SCH80 wall thickness
- 90° and 180° angles
Send the pipe outside diameter, wall thickness, angle and quantity; we will confirm the suitable elbow from stock.
How to Choose?
- Measure the outside diameterDetermine the pipe outside diameter in mm (e.g. 88.9 mm).
- Choose the wall thicknessChoose an elbow matching the pipe wall or SCH value.
- Determine the angleUse 90° for corners and 180° for returns.
- Decide welded or seamlessPrefer the seamless type for steam and high pressure.
