1. Heat Tracing and Insulation Requirements
Metal hoses require proper heat tracing and insulation, especially for smaller diameter hoses of equal length. Install one heat trace on the left side and another directly opposite it, then secure them together using fiberglass insulation. To prevent moisture damage, apply a waterproof coating or install a specialized waterproof shell. Because this can ensure these modifications don’t interfere with normal hose operation.
2. Operational Guidelines
Strict compliance with operating regulations is essential. A frequent cause of metal hose failure is improper valve operation. So you must pay particular attention to correct valve usage during operation.
3. Annual Inspection Procedures
Conduct comprehensive annual maintenance checks by:
Removing the stainless steel hose from the system
Thoroughly cleaning all components
Performing a water pressure test at 1.5 times working pressure for 10 minutes
After drying, conducting an air pressure test at normal working pressure for 15 minutes
Inspection Criteria:
No leaks detected
Metal braiding remains intact without cracks
All nuts securely fastened without loosening
4. Replacement Guidelines
Replace metal hoses when they reach their lower limit position. Then upgrade to a larger size one. After extended service periods, even if not at lower limit.
5. Expected Service Life
Application Inland Areas Coastal Areas
Heavy Oil Tanks 8-10 years 5-8 years
Light Oil Applications 5-8 years 3-5 years
