Capabilities
A capability statement is only useful if it has a boundary. This page is structured to show where ours is, including the parts not yet confirmed.
The envelope
| Capability | Confirmed value |
|---|---|
| Size range | pending verification Smallest and largest bore that can actually be machined and tested |
| Pressure class | pending verification Highest class achievable, including test rig capacity |
| Maximum design temperature | pending verification Governed by the material grades held and the welding procedures qualified |
| Maximum single-piece weight | pending verification Machining, handling and lifting capacity |
| Body material grades | pending verification Grades with stable supply and qualified welding procedures |
These fields are deliberately unfilled. Capability figures are the easiest
numbers on a supplier site to inflate - the size range that includes one valve made once,
the class that the test rig cannot actually reach. They will be filled from what the
facility can demonstrably do, with the test rig capacity and material availability behind
each figure.
Process capability, by stage
The manufacturing route and the record produced at each stage is documented in full on the Manufacturing page, including an explicit note that the in-house versus sourced split must be documented before it is claimed.
| Stage | Detail | Status |
|---|---|---|
| Forging | Open-die and closed-die routes, stated per item | to verify |
| Casting | Cast bodies to WCB, WC6, WC9 and C12A, foundry stated per item | to verify |
| Heat treatment | Normalise and temper; controlled window for creep grades | to verify |
| Machining | CNC turning and machining centres | to verify |
| Hardfacing | PTA and manual GTAW, two-layer Stellite 6 | to verify |
| PWHT | Per qualified procedure, charts per weld | to verify |
| NDE | UT, MT, PT; RT where required | to verify |
| PMI | Every pressure-containing part | to verify |
| Pressure testing | Shell, seat and back seat per API 598 | to verify |
Engineering capability
- Selection review against your duty, including where we would recommend a different valve
- Material selection with the rating calculation shown, not just a grade named
- GA drawings for approval per order
- ITP mark-up before order confirmation
- Compliance review against a client valve specification, split three ways
- Replacement matching from nameplate and dimensional data
- FEA and qualification testing as engineered scope, priced separately
What is outside the envelope
- Control valve trim design and sizing
- Ball, butterfly and plug valve construction
- Continuously abrasive slurry service without an engineered review
- Stock supply on short lead times for creep-grade high-class items
Ask us to prove a capability
If a specific capability matters to your project - a class, a size, a material, a test - ask for the evidence behind it before you order. That is a reasonable request of any supplier and it is the one that separates them.
