OEM compatibility

Engineered as a recognised aftermarket-acceptable replacement for the following OEM equipment lines (Indus Hydraulics is not an authorised distributor of these OEMs — parts are manufactured to the OEM dimensional standard with full mill test reports and API monogram traceability):

• BOP test plug 13-5/8" 10K
• cup-style BOP test plug
• lift sub NC50
• lift sub 5-1/2" FH
• junk sub 13-5/8" 10K

Applications

• BOP testing consumables (per API STD 53 schedule)
• BOP nipple-up consumables
• Wear bushing handling
• Stock per rig in the GCC fleet

Performance & testing

Each unit is dimensionally inspected against the OEM datum, dye-penetrant or magnetic-particle inspected for surface defects, and shipped with mill test reports per EN 10204 3.1 / 3.2. Elastomer parts are batch-tested for hardness, compression set, and fluid resistance (sour service variants tested per NACE TM0297 / TM0187 where applicable). Charpy V-notch impact testing on metallic parts available where service requires low-temperature toughness verification.

Compliance

• API 6A (per part class)
• NACE MR0175 / ISO 15156 (sour-service / H₂S)
• EN 10204 3.1 / 3.2 mill test reports
• Dimensional inspection report per part
• Heat-number / batch traceability

Sealed & dated packaging (GCC climate)

50 °C ambient + UV degrades unsealed elastomers in storage. Indus ships every elastomer / packing element / soft-goods kit in heat-sealed UV-resistant bags with manufacture date, batch number, and recommended-use-by date stamped on the outer label. Re-sealable bins for partial use. This is what Aramco / ADNOC / KOC supplier audits ask about — make sure you specify "sealed dated packaging" on the RFQ.

How to order

Confirm on your RFQ: (a) exact OEM part number or BOP serial number being serviced (we cross-reference to the matched aftermarket part), (b) bore size and working pressure, (c) drill-pipe or casing OD if a ram packer or VBR, (d) elastomer compound preference (HNBR / AFLAS for sour service GCC default), (e) bolting grade (B7M / L7M for sour), (f) certification requirements (NACE, charpy, mill 3.2 vs 3.1, IKTVA / ICV documentation), (g) destination port and packaging requirements.
