Key Features
- API 7K / API 17K Certified — Meets international offshore and drilling safety standards, ensuring reliability in demanding marine environments.
- Fire-Rated Safety Design — Maintains pressure integrity for extended periods under direct flame exposure according to API fire resistance requirements.
- High Pressure Performance — Engineered for working pressures up to 35 MPa (5000 psi) with high fatigue and pulsation resistance.
- Multi-Layer Reinforcement — Features high-tensile steel wire spirals with fire-resistant insulation and protective cover for durability under thermal stress.
- Superior Flexibility — Optimized for tight-space routing and dynamic movement in offshore platforms and drilling rigs.
- Corrosion & Weather Resistant — Outer layer resists saltwater, oil, UV, and ozone exposure for long service life in marine conditions.
Applications
- Hydraulic Tensioner Systems
- Blowout Preventer (BOP) Control Lines
- Riser and Marine Tensioner Systems
- Subsea Hydraulic Controls
- Offshore Drilling and Production Rigs
- Topside Fire-Rated Hydraulic Circuits
Installation & Maintenance Guidelines
- Inspect Before Use: Verify hose integrity and check fire-protection layers before installation.
- Use Approved Fittings: Connect using only API-certified couplings or flanges to maintain safety compliance.
- Protect from Sharp Edges: Avoid routing the hose over abrasive or high-temperature surfaces.
- Conduct Regular Pressure Tests: Periodically inspect hose assemblies to detect early wear or fatigue.
- Replace After Fire Exposure: Always replace hoses that have undergone direct fire incidents to maintain safety integrity.
Frequently Asked Questions (FAQ)
