Surface Test Tree, Conventional Frac API 6BX 10K Flanged, Standard Service

The Surface Test Tree, Conventional Frac API 6BX 10K Flanged, Standard Service is a surface test tree (STT) for conventional frac stt service, 10K class (10,000 psi working pressure), standard rated. Standard service rated for clean hydrocarbon and completion-fluid streams.

Construction

• Configuration: Conventional Frac STT
• Nominal vertical bore: 5-1/8 in vertical bore
• Valves: 5 valves: 2 master, 1 swab, 2 wing
• Valve types: Hydraulic gate valves; manual gate (swab)
• End connections: Top: API 6BX 10K studded. Bottom: API 6BX 10K studded. Lateral: 2× 1502 Female Weco.
• Hydraulic actuation: 3,000 psi pilot
• Material class: AA
• Temperature class: P

Operation

The STT functions as the primary surface pressure-control barrier during well-stimulation, well-test, coiled-tubing, snubbing, or subsea operations. Master valves provide the primary seal; swab valves enable wireline access; wing (lateral) valves route flow to the choke / flowback iron. Hydraulic actuators allow remote operation from the operator's panel — fail-safe close on hydraulic loss. Conventional frac variants stack above the wellhead frac tree to control flowback pressure during frac stimulation.

Performance

Working pressure 10,000 psi (10K class). Hydrotested at 1.5× shell pressure. Designed and manufactured to API 6A. Each valve hydrotested per API 6A / 16C requirements before assembly.

Applications

• Permanent frac STT installations
• Fixed wellhead pressure control
• Multi-stage frac campaign re-use

How to order

Confirm on your RFQ: (a) operation type (frac / coiled-tubing / snubbing / subsea / well-test), (b) target working pressure and pressure class, (c) vertical bore and end-connection requirements (top / bottom / lateral), (d) valve count and types, (e) service class — sour (NACE MR0175) or standard, (f) hydraulic actuation pressure / panel requirements, (g) coiled-tubing pack-off requirement, and (h) certification beyond standard MTRs. Indus quotes ex-Dubai with full FAT (factory acceptance test) report on request.
