## Sourcing pain points we solve

Oil and gas parts work where failure is measured in blowouts, not warranty claims: valve internals and downhole tools see pressure, vibration and H2S-laden sour service simultaneously. NACE MR0175 turns material selection into a compliance question — hardness limits and alloy restrictions that rule out the obvious cheap choice. Every pressure-bearing part needs an EN 10204 3.1 certificate tracing it to a tested heat lot, and a missing cert can quarantine an entire shipment at the wellsite. Procurement swings between urgent rig-down replacements and planned project packages, and suppliers must serve both without compromising documentation.

## Typical parts

- Valve bodies, stems and trim components
- Downhole tool housings and subs
- Flanged connections and hub adapters
- Sensor pressure housings and instrument ports
- PEEK seals, seats and back-up rings

## Certifications & standards

- **API Q1**: We understand API Q1 supply chains and the process documentation discipline oilfield equipment manufacturers flow down to machining suppliers.
- **API 6A**: We understand API 6A requirements for wellhead and christmas-tree components, including material class and PSL documentation expectations.
- **NACE MR0175**: We understand NACE MR0175 sour-service constraints — hardness limits and alloy restrictions are applied at material selection, not discovered at inspection.
- **EN 10204 3.1**: We support EN 10204 3.1 certificates on every pressure-bearing part, tracing it to a tested mill heat lot.

_We understand and support these requirements; certification and documentation scope is confirmed per order — we do not claim to hold certifications on this page._
