Frequently Asked Questions

Can you machine duplex and super duplex stainless?

Yes. We regularly machine Duplex 2205 and Super Duplex 2507 for valve applications. Experienced with work-hardening strategies and chip control. All material certs traceable to mill.

What sealing surface finishes can you achieve?

We achieve Ra 0.4μm on standard sealing surfaces, and Ra 0.2μm or better on lapped metal seats. Concentricity within 0.01mm on seat-to-bore relationships.

Do you offer hardfacing (stellite) on valve seats?

Yes. We can machine pre-stellited components or coordinate with our partners for stellite weld overlay. Finished machining of hardfaced surfaces to customer drawing.

Can you handle NACE MR0175 requirements?

Yes. Materials procured with NACE MR0175 compliance certification. Hardness testing and material verification included. Suitable for sour gas and H₂S service.

What valve types do you support?

Ball valves, gate valves, globe valves, butterfly valves, check valves, and control valves. From 1/4' instrumentation valves to 24'+ industrial sizes.

Do you provide PMI (Positive Material Identification) on all parts?

Yes. PMI testing available on request for all valve components. Report includes elemental composition verification against specified grade. Standard on duplex, super duplex, and NACE jobs.
