What sizes and configurations are available?

This product family covers 5K × 10K studded (bowl × bore) at 5K pressure class and Standard service. Other bowl / bore combinations within the same pressure class can be sourced from the OEM mill on a build-to-order basis (typically 8–16 weeks lead). For complete frac trees, Christmas trees, or wellhead stacks, RFQ with the operator's wellhead drawing or full assembly drawing.

What is the working pressure rating and PSL / PR?

5,000 psi working pressure, 5K class. Manufactured to API 6A, PSL 2, PR1. The PSL determines QA stringency (PSL 1 = baseline, PSL 4 = strictest with full third-party witness). PR1 is non-environmentally-rated; PR2 includes environmental performance testing.

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

No — this is standard-service rated. For sour wells, specify the NACE MR0175 sour variant of this size and pressure class on the RFQ. Sour variants typically use API 6A material class DD, EE, or FF.

What top and bottom connections does this component use?

Top connection: API 6BX 10K studded — to mate with Christmas tree. Bottom connection: API 6B 5K studded — to mate with tubing head. The connection geometry determines what mates above and below — verify ring-groove series (R or RX for API 6B flanges, BX for API 6BX), bolting pattern, and pressure class match the connecting equipment before specifying.

What OEM brands and product lines is this compatible with?

Recognised matched-spec interchange for Stream-Flo THA, Cameron Tubing Head Adapter, FMC SDX TH Adapter. 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 API 6A traceability and OEM-source documentation. For applications requiring an OEM-stamped unit, we can source genuine OEM product on a build-to-order basis.

What materials and material class are used?

Body material: Forged alloy steel (AISI 4130). API 6A material class: AA. This class is standard-service general use. Higher classes (Inconel 625 cladding on seal pockets, F22 / F51 wetted parts, NACE-compliant bolting per B7M / 2HM) 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) PSL 2 / PR1 certification, (c) EN 10204 3.1 mill test report (3.2 on request), (d) hydrostatic shell test certificates to API 6A, (e) hardness reports, and API monogram where the source mill holds the licence.

What is the lead time and how do I order?

Common combinations are short-lead from our Dubai warehouse — typical lead time 28 working days. Custom configurations (sour service, exotic alloys, special porting) ship 12–20 weeks ex-works depending on OEM build slots. RFQ with: wellhead schematic or assembly drawing, target spec (size / pressure class / service), and any agency-specific documentation requirements.

Wellhead components explained: casing head to christmas tree, and the surface test tree

A wellhead is a stack of pressure-containing parts, each holding a string of pipe and sealing an annulus. What each component does from the casing head up, how the christmas tree is arranged, and where a surface test tree fits.
