API 6A Flange
This API 6A Dimensional Specified Adapter (DSA) flange is a reducing type designed to connect two mismatched flange sizes in upstream oil and gas piping systems. It is manufactured to API 6A specifications, with all studs and nuts fully compliant with ASME and NACE MR0175 standards for sour service environments. The flange uses carbon steel WCB or LCC material, per API 6A, and is available in both cast and forged variants.
The adapter flange is engineered for high-pressure applications, ensuring reliable pressure-containing connections in wellhead Christmas tree installations, upstream processing facilities, and transmission pipelines. Typical industry grades for such flanges include ASTM A216 WCB for carbon steel and ASTM A352 LCC for low-temperature service, with dimensions conforming to API 6A tables. Surface finishes are often specified to NACE MR0175 for corrosion resistance in sour gas environments.
Primary buyers include oilfield equipment distributors, EPC contractors, and drilling operators sourcing components for high-pressure systems. The flange is suitable for global import/export trade, with common trade terms including FOB, CIF, or CFR from Chinese ports. Packaging typically involves wooden crates or pallets to prevent damage during transit, with each unit marked for traceability.

Sourcing API 6A Flange from Dongying Lake Petroleum Technology co.,ltd - China Import Guide
Before ordering, verify the flange’s material grade, pressure rating, and dimensional compatibility with your existing piping system. Request the supplier’s API 6A compliance certificate and NACE MR0175 documentation to ensure the component meets sour service requirements. Confirm whether the flange is cast or forged, as this affects its mechanical properties and suitability for your application.
Discuss logistics details such as packaging, marking, and shipping methods to prevent damage during transit. Typical packaging for oilfield flanges includes wooden crates or reinforced pallets, with each unit labeled for easy identification. Clarify Incoterms (e.g., FOB, CIF) and payment terms, as these can vary based on the supplier’s standard practices and your negotiation.
Insist on third-party inspection or witness testing for critical applications, particularly for sour service environments. Check that the flange undergoes non-destructive testing (NDT) such as ultrasonic or magnetic particle inspection. Ensure all documentation, including MTRs and compliance certificates, is provided in English and aligns with your project’s quality assurance standards.
