03 · MATERIALS
What we forge, and what we will not cast
We forge carbon steel, F316, duplex and Inconel 625. We do not supply cast bodies for anything above Class 300, on principle, and have not since 1974.
Carbon steel
A105 · LF2 · LF3
Stainless
F316 · F316L · F304
Duplex
F51 · F53 super duplex
Nickel alloy
Inconel 625 · Monel 400
SINCE 1974
No cast body above Class 300. A casting hides its porosity until the line is up to pressure; a forging does not. It has cost us work and we have kept the rule.
04 · TESTING REGIME
Nothing leaves the bay untested
Every valve gets a hydrostatic shell test at 1.5x rating, a seat test to API 598, and a witnessed certificate with the heat number traceable to the billet.
01
Hydrostatic shell
Every valve, every time, at 1.5x the rated pressure held to the API 598 duration with no visible leakage through the body, bonnet or gland.
02
Seat closure
Seat test to API 598, high pressure and low pressure gas, both directions on bidirectional valves. Rate recorded, not just passed.
03
Cryogenic
BS 6364 immersion testing down to −196 °C in the cryogenic bay, with extended bonnet valves cycled cold before the leak count is taken.

Request a quotation
Technical enquiries go straight to an engineer, not a form queue. Quotations returned in 3 working days for standard configurations.
Send the line size, pressure class, medium and temperature. A P&ID extract or a tag list is enough to start; we will come back with the seat and trim recommendation, not just a price.
