Pipe and piping fittings
Socket-weld tee
Creating a branch from the run pipe or dividing flow
Specialist selection guide
What should be reviewed before selecting this product?
A socket-weld tee creates an integral branch in small-bore piping. Run and branch size, class, grade, branch load and weld details at all three sockets require combined review.
Technical selection path
- 1
Define run and branch sizes
- 2
Match class and forging grade
- 3
Review branch load and support
- 4
Control gap and weld at all three sockets
- 5
Confirm examination and installation access
Key strengths
- Compact integral branch
- Suited to high pressure classes
- Less fabricated branch work
Selection limitations
- Load concentration at the small branch
- Three weld zones require control
- Local branch pressure loss
Typical applications
Where can this option be considered?
- Instrument branches
- Sampling and injection lines
- High-pressure small-bore headers

Common technical questions
Concise answers before enquiry
How is a socket-weld tee class selected?
The fitting class must be matched to material specification, pipe wall, pressure-temperature duty and project piping class.
Does the branch need support?
Valve and equipment weight, vibration and thermal load must be analysed; small diameter does not eliminate support needs.
Equal or reducing branches in a piping network
Run and branch sizes, reinforcement, load direction and stress requirements
