Maintenance of Steel Wire Reinforced Hoses should focus on preventing damage, aging, ensuring proper sealing, and regular inspection. Scientific maintenance can prevent bulging, breakage, and other malfunctions, extending their service life.
Daily use and damage prevention are fundamental. Avoid dragging or rubbing the hose against sharp objects. When bending, maintain the specified minimum bending radius and avoid forced bending. Keep away from high-temperature sources and corrosive media during operation to prevent aging or corrosion of the outer hose layer. Avoid forcefully tightening joints to protect the sealing structure at the interface.
Pressure and media compatibility control are crucial. Operating pressure must be strictly controlled within the rated range. Overpressure operation is strictly prohibited, as it can cause fatigue damage to the steel wire layer. Ensure the transported medium is compatible with the hose material to prevent corrosive media from eroding the inner hose layer and damaging the steel wire reinforcement layer.
Proper storage and maintenance during idle periods are essential. When not in use for extended periods, clean the hose of any residual media, drain excess water, and then coil it properly before storage. Place it in a dry, well-ventilated area, avoiding direct sunlight and humid environments to prevent hose aging and cracking. Also, keep it away from heavy objects to prevent deformation of the steel wire layer.
Regular inspections and hazard identification are key. Before each use, inspect the surface of the Steel Wire Reinforced Hose for bulges and cracks, and ensure the joint seals are intact. Regularly test the hose's pressure resistance; replace it immediately if pressure drop or exposed steel wires are observed. It is recommended to establish a maintenance log to record usage duration and inspection results for precise maintenance.
