Introduction to Composite Hoses‌

‌Structural Composition‌

A composite hose is a flexible pipeline made up of multiple layers of functional materials. It typically includes:

• ‌Inner Lining‌

  : Utilizes corrosion-resistant and medium-resistant polymers (such as PTFE, nylon, etc.) to ensure the purity of the transported liquids.

• ‌Reinforcement Layer‌

  : Constructed from high-strength fibers (such as aramid, steel wire braiding) or fabrics, providing compression and tensile strength.

• ‌Outer Protective Layer‌

  : Made of abrasion-resistant and UV-resistant elastic materials (such as polyurethane, PVC) to adapt to complex environments.

‌Core Characteristics‌

✅ ‌Lightweight and Flexible‌: With a weight of only 1/5 that of metal pipes, it can be bent and coiled for easy installation.
✅ ‌Corrosion Resistance‌: Suitable for various media including acids, alkalis, oils, chemicals, etc., avoiding the corrosion issues of traditional metal pipes.
✅ ‌Explosion-proof Safety‌: No risk of electrostatic accumulation, with some models complying with international explosion-proof standards such as API and EN.
✅ ‌Temperature Adaptability‌: Wide operating range (-50℃ to +200℃), meeting the needs of both high and low-temperature scenarios.

‌Application Areas‌

• ‌Industrial Transfer‌

  : Petrochemicals, shipping, loading and unloading of flammable and explosive liquids in tank trucks.

• ‌Environmental Equipment‌

  : Waste gas treatment, chemical recovery piping systems.

• ‌Food and Pharmaceuticals‌

  : High-hygiene fluid transfer (such as dairy products, pharmaceutical raw materials).

‌Selection Recommendations‌

Choose the corresponding materials and structures based on the characteristics of the medium (corrosivity, viscosity), pressure rating, and ambient temperature. Regularly inspect the seal tightness of the connections and the wear on the outer layer to ensure long-term safe use.
