How to order
Confirm on your RFQ: (a) wellhead bowl size and tubing / casing bore, (b) working pressure and pressure class, (c) top and bottom connection geometry (studded vs flanged, ring-groove series), (d) service class — sour (NACE MR0175) or standard, (e) temperature class, (f) PSL and PR requirements, (g) any custom porting (kill / circulation / instrumentation outlets), and (h) certification requirements. Indus quotes ex-Dubai with full API 6A traceability and OEM-source documentation on request.
Companion products
Pair with matched-class wellhead gate valves (manual or hydraulic), API 6BX flanges, ring-joint gaskets, BSL bolting, casing / tubing hangers, and tree caps in the same pressure class. For frac applications, stack into a frac tree with master valves, swab valves, wing valves, and pressure-release manifolds.
