Flanges.
Pressure-containing connections sourced by design standard, rating, facing, bore, material and inspection requirement.
Defined by the requirement.
We coordinate the sourcing route around material, condition, dimensions, quantity, applicable standard, inspection, documentation and delivery. Manufacturing and processing routes are selected to suit the complete requirement.
| Form / type | Sourcing context |
|---|---|
| Weld neck | Tapered hub for butt-welded pressure connections. |
| Slip-on and lap joint | Assembly-focused designs subject to system requirements. |
| Blind | Closure flanges for piping and equipment openings. |
| Socket-weld and threaded | Compact forged connections within standard limits. |
