Composite Hose

Composite Hose can provide the vital flexible connection to compensate for vibration, movement or misalignment in a fluid transfer system.

Composite hose has a spiral internal metal supporting wire which can be galvanized steel, stainless steel, aluminum or polypropylene coated steel with a spiral external wire which is generally galvanized or stainless steel. In between the wires there are layers of thermoplastic fabrics and film.

The functions of the various components are basically as follows:

Internal wire spiral supports the hose wall and provides resistance to vacuum for suction applications.

External wire spiral armors the hose against abrasion and impact damage and binds the layers of fabrics and films tightly together.

Fabric layers act as strength members against internal pressure. It is also a common feature of many composite hoses to have as the external layer PVC coated fabric. This provides an easily cleanable color coded surface and gives additional abrasion resistance.

Film layers act as a sealing medium to ensure that no product escapes from the hose. Films and fabrics can be polypropylene, polyamide, PTFE, polyester polyaramid or glass. By combining these alternative components in various ways it is possible to produce hoses with a wide range of chemical resistance, working temperatures and pressures.

End fittings as with all types of hose, composite hose assembly depends on the strength and reliability of its coupling system. Loganflex has developed its own unique fitting configuration and swaging system, which uses high quality rubber seals; steel or stainless steel ferrules and couplings to ensure that when prototype tests are conducted, the hose will burst before the end fitting is expelled. This ensures the maximum strength of the hose is fully achieved. Our swaging system gives superior results to wire whipping or clamping methods of attachment, and guarantees electrical continuity to ensure static electricity is fully discharged.

The inner wire is permanently in contact with the coupling. The outer wire is normally in electrical contact but should either of the wires be broken Loganflex uses electrically conductive seals to guarantee continuity. In order to provide the widest range of chemical resistance Loganflex swage seals are available in nitrile, & Viton

Advantages of Composite hoses
  • Better life (Avg. life 18 months to 36 months).
  • Lower in Weight than rubber hoses and much lesser than SS hoses.
  • Flexible, so easier maneuvering and handling.
  • Fatigue free & less ageing compare to rubber hoses.
  • Made up of layers that resists the chemicals & maintains maximum strength, durability, e Flexibility and compatibility with wide rang of chemicals.
  • Having protection from corrosion and attack by other liquids, UV Radiation and ozone by their tough, PVC –impregnated fabric covers.
  • Meets the electrical continuity requirements for industrial applications.
  • Temperature tolerance from -30 to +80 C.
  • Does not contaminate the fluid like clean fuel/oil while transferring. In other words, the original quality of liquid remains same while transferring.
  • Composite hoses are unto 30% lighter than rubber hoses.
  • The materials used in composite hoses are fatigue free and do not degrade like rubber
  • The fluid passing through rubber hoses may be contaminated by the tiny particles of Rubber whereas in composite hose the inner layer is polypropylene fabric which Will not contaminate the fluid.
  • The composite hose can be given in different colors for different applications so that the hoses dedicated for a particular application can be easily identified.
  • Composite hoses on an average have a longer life than rubber hose.
  • Electrical continuity is maintained throughout the life of the composite hose.
