Product Lines
CRC Wellhead machines to three independent approvals — the API 6A monogram (6A-2231, Spec Q1-4221), an ABSA-registered CRN for pressure equipment (0B26482.2, AQP 5061) and APEGA Permit 13181 — which cover the monogrammed wellhead products and registered spool adaptors shown below. Outside that scope we are unrestricted on material, connection and size: our engineers and machinists work from your drawings or ours to produce anything from a single prototype to a full production run for oilfield, industrial, mining, pulp & paper and hydrogen service, with full traceability and test records on every part.

Custom Machining
Our team of engineers and machinists will consult with you to design and manufacture any shape from any material to meet your exacting requirements.
Outside the scope of the 6A monogram and the CRN, we are not restricted on material or connection. These parts carry full traceability and test records — they simply do not carry a monogram, and we never imply otherwise.
