σωλήνας υψηλής πίεσης

Types of Pressure Hoses

1. καουτσούκ σωλήνες και μάνικες

  • Structure: Typically made from nitrile rubber, with textile braid for low pressure and high-strength steel wire for high pressure.
  • Πλεονεκτήματα: Good flexibility, compatibility with various hydraulic oils, and excellent performance at low temperatures.
  • Μειονεκτήματα: Prone to degradation from UV light and abrasion.

2. Thermoplastic Hoses

  • Structure: Made from a nylon tube, synthetic fiber reinforcement, and polyurethane outer layer.
  • Πλεονεκτήματα: High safety factor (4:1), excellent abrasion resistance, suitable for high-pressure spikes and high-cycle applications.
  • Μειονεκτήματα: Poor elasticity in cold environments and has memory effect, making it difficult to lay flat after coiling.

3. Steel Braided Hoses

  • Structure: Single or double wire braid, designed for extreme pressures and temperatures.
  • Εφαρμογές: Used in oil fields, mining, and heavy industrial applications.

Ασφάλεια και συντήρηση

Using high-pressure hoses involves significant risks, including potential injuries from hose whipping, leaks, and bursts. Proper safety measures and regular maintenance are crucial to preventing accidents.

Συμβουλές για την ασφάλεια

  • Εξοπλισμός ατομικής προστασίας (PPE): Always wear appropriate PPE, including hard hats, safety glasses, and gloves.
  • Hose Safety Devices: Use hose safety devices like whip checks, whip stops, and hose chokes to prevent hose whipping in case of failure.
  • Τακτική Επιθεώρηση: Regularly check hoses for signs of wear, damage, or leaks. Replace any damaged hoses immediately.
  • Ο σωστός χειρισμός: Avoid pressurizing coiled hoses and ensure hoses are properly coiled and stored when not in use.

Pressure hoses are vital for ensuring efficient and safe operations in various applications. Selecting the right type and maintaining proper safety protocols can significantly enhance performance and longevity while minimizing risks.
