The schedule for re-inspecting rubber-plastic hoses after replacement should be flexibly adjusted based on the operational stage and service conditions. Specific guidelines are as follows:
Initial Inspection (Post-Installation)
A comprehensive inspection must be completed within 1–2 weeks of the hose being put into service to promptly identify issues such as improper installation or initial operational compatibility problems.
Routine Daily Inspection
Under standard operating conditions, it is recommended to conduct a visual and operational status check every 1–3 months to confirm there are no abnormalities with the hose body.
Inspection for Special Operating Conditions
For harsh conditions involving high temperatures, high pressures, or strong vibrations, a thorough, in-depth inspection is recommended every 6–12 months.
For gas-service rubber-plastic hoses, routine leak checks must be performed at least once a month to mitigate leakage risks.
For spare rubber-plastic hoses held in long-term storage, it is recommended to rotate and inspect them every six months to prevent aging caused by prolonged localized compression.
