Top 5 Causes of High-Pressure Hydraulic Hose Bursting
In industrial operations, highpressure hydraulic hose failures rank among the most frustrating challenges for equipment managers. A sudden hose burst can lead to equipment downtime, fluid leaks, and potentially serious safety incidents, causing personnel injuries and significant financial losses. So what exactly causes highpressure hydraulic hoses to burst? And how to select truly reliable products? This article provides an indepth analysis of failure causes and recommends LETONE hydraulic hose solutions an industry leader!
I. Top 5 Causes of HighPressure Hydraulic Hose Bursts
1. Exceeding Rated Working Pressure (35% of cases)
Symptoms: Sudden system pressure spikes beyond hose capacity
Common scenarios:
Failed pressure control valves
Cylinder encountering abnormal resistance (e.g., jamming)
Hydraulic shock (water hammer effect)
✓ LETONE Solution: Products with dual pressure protection (working pressure + burst pressure), withstand up to 6000+ PSI
2. Hose Degradation (28% of cases)
Symptoms: Outer layer cracking, inner tube swelling/delamination
Main causes:
Prolonged exposure to high temps (>100°C/212°F)
Contact with corrosive fluids/chemicals
Continued use beyond service life
✓ LETONE Advantage: Hightemp NBR rubber + antiaging formula extends service life by 50%
3. Improper Installation (20% of cases)
Common mistakes:
Bending radius smaller than minimum requirement
Twisted installation
Substandard crimping
Friction against sharp edges
✓ LETONE Support: Provides professional installation guidance + preformed hoses
4. Pulsation Fatigue (12% of cases)
Failure pattern: Progressive wire breakage
Highrisk equipment:
Highcycle injection molding machines
Construction machinery systems
Test benches
✓ LETONE Technology: 6layer ultrahigh tensile wire braid, passes ISO 6802 impulse testing (>500,000 cycles)
5. External Mechanical Damage (5% of cases)
Typical situations:
Cut by metal edges
Crushed by heavy objects
Burned by welding slag
✓ LETONE Protection: Optional abrasionresistant cover + Kevlar reinforcement, 3x better impact resistance
II. 3 Severe Consequences of Hose Failures
