The buyer’s guide
About our pipe stub ends
Stub ends machined for lap-joint service where flanges must rotate or exotic alloy must be minimized. Every piece is machined or modified in our Houston shop with heat traceability end to end.
- Lap-joint service
- Machined faces to B16.9-compatible dimensions
- Exotic alloys where they matter, carbon backing flanges where they don't
Tips for purchasing
- Give the size, rating and material — or the line spec — and we take it from there.
