A fuel tanker is a special vehicle for transporting liquid fuels such as petroleum and diesel, widely used for energy transportation in Africa and the Middle East. As the most critical safety component of the fuel tanker tank, the safety valve automatically releases pressure when the internal tank pressure rises abnormally to avoid tank deformation or explosion. Following the maintenance cycle strictly is essential to guarantee transportation safety and daily operation of exported fuel tankers.https://www.hjtrailer.com/truck/tank-truck/howo-8x4-fuel-tanker-truck.html
Standard maintenance cycle for safety valve
- Daily inspection (before each departure) Visually check the appearance of the safety valve to ensure no corrosion or leakage and intact protective cover. Inspect and clean the exhaust port to remove dust and oil stains. This inspection is required for all brand new fuel tankers.
- Short-term maintenance (every 6 months) Carry out on-site function test every 6 months to verify normal opening and resetting of the safety valve. Clean impurities inside the valve and check wear on sealing surfaces. This cycle is recommended for fuel tankers operating in high-temperature and dusty areas of Africa and the Middle East.
- Professional calibration (once a year) Professional technicians must complete pressure calibration annually to test opening pressure and sealing performance. Keep calibration records after inspection. According to international safety standards, the fuel tanker safety valve cannot be used beyond the valid period.
- Mandatory replacement cycle (every 2 years) Even if the calibration result is qualified, the safety valve is recommended to be replaced every 2 years. Long-term medium corrosion and repeated pressure cycles will cause spring fatigue and hidden failure risks. If the tank suffers collision, the safety valve must be inspected or replaced immediately.
Important Notes
- Do not adjust the pressure setting of the safety valve without authorization. Any modification will damage the tank safety protection.
- Shorten the calibration cycle appropriately for fuel tankers working under high-temperature conditions.
- Stop transportation immediately for repair if the safety valve leaks, gets stuck or fails to reset.
- Spare parts for fuel tanker safety valves can be supplied together with exported vehicles to support overseas maintenance.
