Product specification
Flanges & Forgings
Weld-neck, slip-on, threaded, socket-weld, lap-joint and blind flanges from 1/2" upwards, machined in-house on the same CNC centres that finish our valve bodies.
Overview
Carbon, low-temperature, alloy, stainless and duplex grades are stocked and processed regularly, supplied with EN 10204 3.1 material certificates and full heat traceability. Special dimensions and non-standard facings are routine work, not exceptions.
Design features
- One quality system — flanges and valves share the same machining floor and inspection regime
- RTJ grooves and special facings machined to order for critical joints
- Matched-material sets — order companion flanges matching your valve bodies exactly
- Project quantities supported by organised stockholding and planned production slots
- Export packing with seaworthy crating and full documentation dossiers
