Pipe and piping fittings
Socket-weld elbow
Changing line direction with a defined angle and radius
Specialist selection guide
What should be reviewed before selecting this product?
A high-pressure socket-weld elbow changes direction in small-bore piping. Fitting class, forging grade, socket depth, pipe-end gap and fillet-weld quality must match the piping class.
Technical selection path
- 1
Define fitting class and forging grade
- 2
Check size, socket depth and assembly gap
- 3
Review orientation and welding access
- 4
Evaluate cyclic duty and crevice-corrosion risk
- 5
Specify material and examination records
Key strengths
- Compact small-bore construction
- Suitable strength in high classes
- No process-exposed thread
Selection limitations
- The socket gap can form a corrosion crevice
- Cyclic service requires special review
- Fillet-weld quality depends on access
Typical applications
Where can this option be considered?
- High-pressure drains and vents
- Small-bore process connections
- Steam and instrument piping

Common technical questions
Concise answers before enquiry
Why is an assembly gap left in a socket?
A controlled gap reduces load from pipe-end thermal expansion against the socket bottom; the project procedure must define its value and assembly method.
Is socket welding suitable for cyclic service?
It must be checked against the code and project specification because weld geometry and the internal crevice can affect fatigue.
