Composite Hoses
Hongruntong Marine’s PTFE-lined composite hoses are engineered for safe, reliable transfer of aggressive chemicals, refined fuels and cryogenic liquids in marine and industrial environments. Combining a chemically inert PTFE inner liner with high-strength reinforcement layers and abrasion-resistant outer covers, our composite hoses deliver exceptional chemical compatibility, flexibility and long service life. Suitable for ship-to-shore transfer, bunkering, offshore platforms and on-board systems, these assemblies are manufactured under strict quality controls to meet customer-specified standards.
Features & Benefits
| Features | Benefits |
|---|---|
| Seamless PTFE Lining | Provides excellent chemical resistance to a vast range of aggressive chemicals, solvents, and oils, ensuring product purity and preventing contamination. |
| Lightweight & Flexible Composite Structure | Easier to handle and install compared to metal hoses, reducing labor costs and fatigue. Excellent for applications requiring frequent movement or complex routing. |
| High Strength Synthetic Fiber Braid | Offers high pressure resistance and maximum tensile strength, preventing hose kinking and bursting under pressure, thus enhancing safety. |
| Conductive Wire Option | Built-in static electricity dissipation for safe transfer of flammable liquids, significantly reducing the risk of fire or explosion. |
| Temperature & Weather Resistance | Maintains flexibility and performance in a wide temperature range and under various weather conditions, ideal for global operations. |

FAQ
Q1: What does "composite hose" mean?
A: A composite hose is a flexible pipe constructed from multiple layers of different materials (e.g., PTFE, fabric, wire, polymer). Each layer is designed to provide a specific property like chemical resistance, strength, or flexibility, resulting in a lightweight, safe, and highly durable solution superior to traditional rubber or metal hoses for many applications.
Q2: Why is PTFE lining so important?
A: PTFE (Teflon®) is one of the most chemically inert materials known. A seamless PTFE liner creates an impermeable barrier that prevents even the most aggressive chemicals from degrading the hose structure, ensuring safe transfer and protecting the product from contamination.
Q3: Are your hoses suitable for ship-to-ship (STS) transfer?
A: Absolutely. Our PTFE composite hoses are ideally suited for STS operations due to their flexibility, lightweight nature (easier to handle on deck), excellent chemical resistance for various cargoes, and availability with conductive elements for safe static dissipation, fully complying with OCIMF guidelines.
Q4: How do I determine the right hose size and type for my application?
A: Please contact our technical sales team at [Your Email/Phone]. We will need to know the specific chemical(s) being transferred, concentration, temperature, working pressure, and the type of end connections required to recommend the perfect hose for you.
Q5: Do you offer custom lengths and fittings?
A: Yes, we specialize in providing customized solutions. We can fabricate hoses to your exact length and fit them with a wide range of international standard flanges, camlocks, and other end connections.
