Oil Hose Strong Flexibility Leak Resistant Long Service Life Heat Proof

Description

The Hongruntong Fuel Hose Pipe represents the latest advancement in marine fuel transfer technology, designed to deliver high reliability, safety, and efficiency in diverse maritime environments. Engineered with a specialized multi-layer composite structure, the hose combines a high-grade synthetic inner tube with braided reinforcement and an abrasion-resistant outer jacket. This construction ensures exceptional chemical stability, durability, and resistance to environmental stressors such as saltwater, UV radiation, and mechanical impact.

The inner tube is formulated to withstand a broad range of fuels including diesel, gasoline, biodiesel, and light fuel oils, maintaining leak-free performance under continuous operation. The reinforced layers provide structural integrity under high pressure, preventing bulging or collapse during suction and discharge operations. Its flexible design allows for smooth routing around tight bends, deck obstacles, and complex piping layouts without compromising flow efficiency.

Each hose undergoes rigorous quality testing to meet international marine standards, including ISO 7840, SAE J1527 Type A1, and EN 1360. Tests cover burst pressure, vacuum integrity, chemical compatibility, abrasion resistance, and hydrostatic performance. Hongruntong hoses are available in a variety of diameters, lengths, and pressure classes, and can be fitted with camlock, flange, or threaded couplings to accommodate vessel, terminal, or offshore fuel systems.

This combination of chemical resistance, structural durability, environmental protection, and operational flexibility makes the Hongruntong Fuel Hose Pipe an optimal solution for marine fuel transfer in ports, shipboard systems, and offshore platforms.

Case Study

In 2023, a Mediterranean naval support base required a flexible and reliable solution for refueling patrol and auxiliary vessels. The existing rigid piping system caused fuel leaks, difficult maintenance, and limited maneuverability on the dockside. Hongruntong Marine proposed a full replacement with HRT-MarineFlex 500 Fuel Hose Pipes.

Over 600 meters of hoses were installed, connecting storage tanks to refueling manifolds and mobile fueling units. The hoses featured a high-strength synthetic rubber inner tube, double-layer braided reinforcement, and a flame-retardant, abrasion-resistant outer jacket. Stainless steel camlock couplings were fitted to allow fast and secure connection while preventing leaks.

During installation, hoses were routed along complex docks, passing over bollards, cranes, and uneven surfaces. The flexible design facilitated smooth bends without kinking or flow restriction. Following installation, hydrostatic and chemical resistance tests were conducted to verify compliance with ISO and SAE standards.

Operational results were significant: fuel transfer times improved by 40%, maintenance downtime was reduced by 50%, and the hoses maintained full performance despite daily exposure to sunlight, salt spray, and high traffic on the dock. This project demonstrated Hongruntong’s ability to deliver durable, safe, and efficient marine fueling solutions adaptable to complex operational environments.

Key Features

Dynamic Flex Reinforcement Technology
Hongruntong Fuel Hose Pipes incorporate a spiral-reinforced inner layer combined with flexible textile strands arranged at multi-angles. This design distributes mechanical stress evenly along the hose, preventing localized fatigue, kinking, or deformation under repeated bending and high-pressure pumping. It ensures consistent flow, reduces turbulence, and extends operational life in mobile or offshore applications.

Chemical and Biofuel Compatibility Layer
The inner tube is made from a proprietary elastomer blend that resists permeation and chemical attack from high-ethanol fuels, biodiesel, synthetic oils, and aromatic hydrocarbons. This layer maintains integrity over long-term use, preventing leaks or contamination while accommodating diverse fuel types in industrial and marine operations.

Extreme Environmental Durability
The outer jacket is engineered to withstand UV radiation, ozone exposure, saltwater, and mechanical abrasion from handling, deck machinery, or accidental impacts. Its high-toughness elastomer ensures the hose remains flexible and resilient under harsh conditions, reducing maintenance frequency and prolonging service life in demanding port and offshore environments.

Integrated Safety and Visual Monitoring
Certain models include embedded conductive elements to dissipate static electricity safely during fuel transfer, minimizing fire risk. Optional visual tracer or wear-indicator layers provide early warning of surface degradation, enabling proactive maintenance and improving operational safety and environmental compliance.

Applications

Port Bunkering Operations: The hoses are ideal for refueling ships at dockside, providing efficient and safe transfer of marine diesel, gasoline, and light fuel oils. Their flexible design allows smooth handling across decks and through tight spaces, reducing operational time.

Shipboard Fuel Systems: Designed for connecting day tanks, main storage tanks, and engine systems, these hoses maintain reliable fuel flow under dynamic vessel movement and mechanical vibration. High chemical resistance ensures compatibility with a variety of fuels.

Offshore Fuel Supply: Suitable for offshore platforms, service vessels, and floating bunkering stations, the hoses resist corrosion, UV, and mechanical abrasion while maintaining flow stability in exposed marine environments.
