What sizes are available in this product family?

Stock or short-lead sizes: 2-1/16 in, 3-1/8 in. The product page consolidates a family of sizes that share the same series, configuration, pressure class, and service class — confirm the exact size you need on the RFQ. Sizes outside the listed stock range can be sourced build-to-order at typical 8–14 week lead times depending on OEM build slots.

What is the working pressure rating?

5,000 psi working pressure, 5K class. The unit is hydrostatically shell-tested to API 6A. The working pressure is fixed by both the body design and the end connection — the union, flange, or weld rating is the limiting factor at the joint, so always specify matched-class connections on both sides.

Is this product suitable for sour service (H₂S wells)?

No — this is standard-service rated. For sour wells (H₂S partial pressure above NACE MR0175 thresholds), specify the sour-service variant of this size and pressure class on the RFQ. A sour-service API flange keeps its pressure class — the difference is hardness-controlled material to NACE MR0175, not a lower rating.

What end connections does this product use?

End A: API 6B 5K flange (R or RX ring groove). End B: 602 Female Weco Union. These are API 6A / 6B flanged ends — ring-joint gasket (RTJ) sealing on an R or RX ring groove. Studs and nuts to match the API 6B bolting pattern (BSL stud-and-nut sets are sold separately).

What OEM brands and standards is this compatible with?

This product is supplied as a recognised matched-pressure interchange for Cameron 5K, FMC WECO 602, Stream-Flo 5K. Indus is not an authorised distributor of these OEMs but every unit is engineered to be dimensionally and metallurgically interchangeable with the named OEM standard, with full mill test reports and hydrostatic certificates on file. For applications requiring an OEM-stamped unit, we can source genuine OEM product on a build-to-order basis — call us with the application detail.

What materials and material class are used?

Material: Forged alloy steel (4130/4140), tempered. API 6A material class: AA (standard-service general use). Higher material classes (Inconel-clad seal pockets, F22 / F51 wetted parts, NACE-compliant bolting) are available on request for severe sour, high-temperature, or chloride-rich service.

What standards and certifications come with each unit?

Each unit ships with: (a) API 6A design and manufacture compliance, (b) EN 10204 3.1 mill test report (3.2 on request), (c) hydrostatic shell test certificate to API 6A, and traceability stamps on the body. API monogram is available where the source mill holds the licence — flag this on the RFQ if it's a hard requirement.

What is the lead time and how do I order?

Common combinations are stocked or short-lead from our Dubai warehouse — typical lead time 14 working days. Sour-service variants and unusual sizes / pressure classes ship 8–14 weeks ex-works depending on OEM build slots. RFQ with: (a) exact size, (b) pressure class and service, (c) end-connection style and gender on each port, (d) certification requirements, and (e) destination port. Indus quotes ex-Dubai with door-to-door logistics on request.
