The installation quality of steel wire rubber hoses directly affects their service life and safety performance. Improper installation is a major cause of premature failure.
I. Pre-installation Inspection and Preparation
Inspect the inner and outer surfaces of the hose for cracks, bulges, or impurities, and ensure the hose markings are clearly legible. Check that the joints match and confirm the sealing surface is intact. Cut the hose end to ensure it is flat and vertical, and remove any rubber debris.
II. Connection and Installation Specifications
Use crimp-type fittings for steel wire rubber hoses, with crimping equipment operated by qualified personnel. The hose should be inserted into the metal hose by at least 15 cm, secured with double clamps or wire. After connection, check for excessive bending at the joint; add spring sleeves if necessary.
III. Hoses Laying Specifications
The bending radius should not be less than the specified minimum; sharp bends will damage the steel wire reinforcement layer. There should be no torsion after installation; ensure the hose extends naturally. Install fixed supports every 1-1.5 meters to prevent vibration and friction. Install rubber sleeves when passing through metal holes.
IV. Post-Installation Inspection
Slowly increase the pressure to the working pressure, check for leaks at the joints, and observe the deformation of the hose under pressure. Once no abnormalities are confirmed, it can be put into use.
