Composite Hose Manufacturer

The composite hose consists of a polypropylene fabric inner liner, a multi-layer spiral thermoplastic fabric reinforcement layer, inner and outer double-layer spiral steel wires, and a PVC-coated outer sheath. All hoses are manufactured according to European standard EN13765:2015, and each hose undergoes individual water pressure and resistance tests before leaving the factory. Compared with traditional rubber hoses, composite hoses offer greater pressure resistance and are less prone to deformation. Its inner structural material is tear-resistant and corrosion-resistant, and can transport a variety of corrosive chemical fluids.

Rentone Hose is well-known as a comprehensive composite hose supplier in China. We have advanced manufacturing equipment and rich expertise in the industry. So we can manufacture high-quality China composite hoses for global customers. Our factory can handle and operate many composite hose lines. It can ensure adequate supply on the market. Rentone Hose can customize composite hoses based on samples, drawings, or customer requirements.

Composite Hose Construction

  • Inner wire: Options include SS316 stainless steel wire, hot-dip galvanized steel wire, aluminum alloy wire, or PP-coated steel wire, depending on the medium being conveyed.
  • Outer wire: Common options include hot-dip galvanized steel wire, SS316 stainless steel wire, and aluminum alloy wire.
  • Inner lining: Options include functional materials such as polypropylene (PP) and polytetrafluoroethylene (PTFE).
  • Seamless layer: Enhances the hose's leak-proof performance.
  • Reinforcement layer: Composed of multiple layers of functional polymer films and synthetic fiber fabrics.
  • Outer cover: Composed of wear-resistant, waterproof, and aging-resistant PVC-coated fabric.

Material selection for composite hoses requires consideration of factors such as the conveyed medium, operating temperature, pressure rating, and application environment. If you are unsure about the material, please provide details about the medium type, operating pressure, and operating temperature. We will recommend a suitable composite hose solution for you.

Features And Benefits of Composite Hose

  • Excellent oil and chemical corrosion resistance
  • Lightweight: Flexible composite hoses are 30-40% lighter than ordinary rubber hoses
  • Double-layer steel wire connection, providing an excellent static electricity discharge function
  • Adopting a joint crimping process, ensuring good sealing and greater strength
  • Good temperature resistance; does not soften or harden within the operating temperature range.
  • Small bending radius, can be bent arbitrarily, suitable for various working conditions
  • Excellent pressure resistance, resistant to positive and negative pressure, good performance.
