Industries / Oil & Gas
Oil & gas components
Corrosion-resistant machined parts for valves, pumps, wellhead equipment and process plant — built for pressure, temperature and traceability.
Why manufacturers in this sector work with us
Oil and gas work is unforgiving: a leaking seal face or an out-of-round bore takes a whole skid out of service. We machine sealing surfaces, flanges and bores to the concentricity and finish the sealing system was designed around, then verify them before anything ships.
Material traceability matters as much as geometry. We record heat numbers, retain material certificates and issue inspection documentation with every consignment so your own QA package stays complete.

Frequently asked questions
Can you supply material certificates?
Yes — EN 10204 style mill certificates are retained and supplied with the parts, along with our own dimensional inspection report.
Do you machine sealing faces to a specified Ra?
Yes. Call out the required roughness on the drawing and we will finish and verify to it.
Can you reproduce an obsolete spare?
Send us the worn part. We 3D scan it, rebuild the CAD, agree the corrections with you and machine the replacement.
