Mainline Submarine Hose

Hongruntong Marine, a globally recognized manufacturer of marine fluid transfer solutions, proudly presents its GMPHOM2009-certified Mainline Submarine Hose—engineered to redefine reliability in offshore oil, gas, and industrial applications. Combining rigorous compliance with innovative design, our hoses deliver unmatched performance in the harshest subsea environments.

Advanced Engineering for Critical Operations

Designed to meet and exceed GMPHOM2009 standards, our Mainline Submarine Hose ensures full traceability from raw material sourcing to final quality inspection. The hose’s robust construction features a four-layer architecture:

• Oil-resistant synthetic rubber inner layer (Shore A 75-80) for maximum fluid compatibility

• Dual high-tensile steel wire reinforcement spirals to withstand pressures up to 35 bar

• Abrasion-proof chloroprene outer cover with UV stabilization for prolonged sun exposure resistance

• Integrated anti-kink technology to maintain flow efficiency even in complex subsea configurations

Each unit undergoes hydrostatic testing (1.5 x working pressure) and is backed by DNV-GL and API 17K certifications, guaranteeing compliance with international offshore safety protocols.

Operational Advantages Driving Industry Leadership

1. Extended Durability
With a minimum service life of 15 years under standard operating conditions, our hose reduces replacement frequency by 30% compared to conventional models. The proprietary compound resists cracking, ozone degradation, and saltwater corrosion, even in temperatures ranging from -40°C to +80°C.

2. Enhanced Safety & Efficiency

• Zero-leak guarantee through precision-machined flange connections (ANSI/DIN standards)

• 30% faster deployment with our patented quick-coupling system

• Real-time monitoring compatibility via embedded RFID tags for pressure and wear analytics

3. Global Adaptability
Customize your hose with optional features:

• Adjustable buoyancy modules for precise subsea positioning

• Acid-resistant lining for chemical injection applications

• Arctic-grade materials for operations in polar regions
