Adjustable Manual Choke, H2 Trim, 3-1/8 in × 5M Flanged BW, 3 in Nom / 2 in Max Bean, 5,000 psi, Sour Service

The Adjustable Manual Choke, H2 Trim, 3-1/8 in × 5M Flanged BW, 3 in Nom / 2 in Max Bean, 5,000 psi, Sour Service is a adjustable manual choke valve rated for 5,000 psi working pressure (5K class), 3-1/8 in API 6A 5M Flanged (RTJ) inlet × 3 in Butt-Weld (Schedule 160) outlet, H2 trim. NACE MR0175 / ISO 15156 sour-service compliant.

Adjustable manual choke — handwheel rotates a threaded stem to vary the trim opening, controlling flow rate / back-pressure on the wellhead or test train. The H2 trim is replaceable as a service item — stem and seat can be removed without taking the body out of line. Bean / orifice maximum: 3 in nominal / 2 in max.

Construction

• Type: Choke — Adjustable Manual
• Trim model: H2
• Bean / orifice: 3 in nominal / 2 in max
• Nominal size: 3-1/8 in
• Body material: Forged AISI 4130 — NACE MR0175 compliant
• Trim material (stem / bean / seat): Tungsten-carbide bean + Inconel 625 stem + TC seat
• Seal / packing: HNBR + graphite packing (sour)
• Inlet: 3-1/8 in API 6A 5M Flanged (RTJ)
• Outlet: 3 in Butt-Weld (Schedule 160)

Performance

Working pressure 5,000 psi. Variable-orifice flow control by handwheel — full closed to 3 in nominal / 2 in max fully open. Position indicator on the bonnet shows current opening. Tungsten-carbide trim resists erosion in sand-laden flow. NACE MR0175 sour-service compliant — material class EE.

Applications

• 5M wellhead choke manifolds
• Flanged-to-welded production lines
• Sour-gas processing inlets
• 5K production tree side outlets

Compliance

• API 6A PSL 3 PR1
• Material class EE (API 6A chemistry / sour-service grading)
• NACE MR0175 / ISO 15156 (sour-service)
• Mill test reports per EN 10204 3.1 / 3.2

How to order

Confirm (a) upstream and downstream pressure (the choke must handle the full ΔP across the trim), (b) inlet and outlet end-connection sizes / styles, (c) service class (standard vs sour), (d) trim model preference (N-60 for compact / lower-flow service, H2 for high-flow / 3-inch lines), (e) any auxiliary features (autoclave tap for pressure / sample, gear handwheel for high-torque). Indus quotes ex-works OEM for build-to-order, with full mill test reports and pre-shipment hydrotest certificates.

Companion products

Pair with matched-pressure block valves (ball, gate, plug) upstream and downstream of the choke. For frac iron, the 1502/602/206 Weco union family is the matched standard. For data-rich operations, also specify autoclave taps with matching pressure transmitters and / or sample bombs.
