The steel-wire reinforcement is a major contributor to a hydraulic hose’s pressure capacity. Braided or spiral wire forms the load-bearing structure. The following observations can help distinguish common failure mechanisms.
Corrosion near the rupture
Rust on the reinforcement near a burst can indicate moisture or corrosive substances entering through a damaged cover. Cracking, abrasion or deterioration may have removed the outer cover’s protective function. Identify mechanical damage, chemical attack or excessive heat before replacing the hose.
Corrosion near the fitting
The cover can appear intact while the reinforcement corrodes. When failure occurs within roughly 200 mm of a fitting, an unsuitable connection may have allowed moisture to enter beneath the ferrule, reducing the hose’s pressure strength.
Broken wire without corrosion
Irregular broken wires along the reinforcement, with no visible rust, can indicate repeated high-frequency pressure impulses.
