Coiled Tubing Quad BOP, 5-1/8" 10,000 psi WP, Sour Service (NACE MR0175)

The Coiled Tubing Quad BOP, 5-1/8" 10,000 psi WP, Sour Service (NACE MR0175) is a complete coiled tubing quad bop unit rated for 10,000 psi working pressure (10K class) in sour service (nace mr0175). The 5-1/8" 10K CT Quad BOP carries four ram cavities in a single body — typically arranged as blind ram (top), shear ram, slip ram, pipe ram (bottom). Coupled below the CT injector head and above the wellhead riser. Driven by ADNOC / Aramco / QatarEnergy CT campaigns post-2021. NACE MR0175 / ISO 15156 sour-service compliant — full body, trim, and bolting hardness controlled per the standard. Required across Saudi Aramco, ADNOC, KOC, PDO, and QatarEnergy default specifications for sour fields.

OEM compatibility

Engineered as a recognised matched-pressure interchange / supply for the following OEM equipment lines (Indus Hydraulics is not an authorised distributor of these OEMs — units are sourced through Indus and supplied with full traceability):

• Cameron CT 5-1/8" 10K Quad
• NOV CT Quad 5-1/8" 10K
• Hydril CT 5-1/8" 10K Quad
• Jereh CT Quad 5-1/8" 10K

OEM cross-reference: Cameron CT 5-1/8" 10K Quad, NOV CT Quad 5-1/8" 10K, Hydril CT 5-1/8" 10K Quad — standard four-ram CT stack arrangement (blind, shear, slip, pipe).

Applications

• Coiled tubing stimulation (acid, fracturing, scale removal)
• CT cleanout and milling on producing wells
• CT logging and intervention
• Aramco / ADNOC / KOC CT well intervention campaigns

Performance & testing

Hydrostatic shell test at 1.5× rated working pressure on every unit. Function-test on rams, packers, and seal elements per API STD 53. Mill test reports per EN 10204 3.1 / 3.2 supplied. Charpy V-notch impact testing at low temperature available where service requires toughness verification. Closing-time and seal-pressure data sheets included with FAT package.

Compliance

• API 16A (per equipment class)
• NACE MR0175 / ISO 15156 (sour-service / H₂S)
• EN 10204 3.1 / 3.2 mill test reports
• Hydrostatic test certificates per unit
• Heat-number traceability stamped on body
• FAT (factory acceptance test) report on request

How to order

Confirm on your RFQ: (a) exact bore size, (b) working pressure and pressure class, (c) ram configuration / cavity count (where applicable), (d) end connection family (API 6A studded, flanged, or bolted), (e) service class — sour (NACE MR0175), HPHT, or standard, (f) elastomer compound preference (HNBR / AFLAS for GCC sour service), (g) FAT witness requirement, and (h) destination port for door-to-door logistics. Indus quotes ex-Dubai (AED) with Aramco / ADNOC / KOC vendor-registered logistics support.

Region notes

Stocked / sourced for the GCC: Saudi Arabia (Aramco IKTVA), UAE (ADNOC ICV), Kuwait (KOC), Oman (PDO), Qatar (QatarEnergy), Bahrain (BAPCO), and Iraq south. Sour-service trim is the regional default; Indus carries sour-service variants in stock and treats sweet-service as a build-to-order downgrade.

Companion products

Pair with matched-pressure 10K BOP control unit (Koomey-style accumulator), API 16C choke & kill manifold, BX ring gaskets, B7M studs and 2H nuts (sour service), HNBR / AFLAS elastomer kits, and matching drilling spool / DSA crossover. Annual redress kits and 5-year API 16A recertification service available — see the BOP Services category.
