Precautions for valve maintenance of low-temperature storage tanks: Price trend of 60 cubic meter LNG storage tanks

Description :

　　If there is suspicion of a valve malfunction, disassemble and repair it according to the following methods. If there is a leakage at the valve seal, tighten the sealing nut first to see if the leakage stops, and then remove the valve.

　　 Note: If valve components are in stock, replace the faulty valve with a new one.

　　If repairing a valve that comes into direct contact with liquid, all liquid in the storage tank must be drained.

　　2. Open the gas discharge valve (A-12) to release all pressure.

　　3. Remove the valve cover from the faulty valve.

　　4. Remove the valve seat.

　　5. Disassemble the valve and inspect all individual components.

　　6. Clean all metal parts with suitable bleach, and thoroughly rinse other parts with hot water.

　　7. Blow dry all components with clean, low-pressure air.

　　8. Replace all worn, deformed, or damaged parts.

　　9. To reseal the valve, PTFE filaments can be placed inside or wrapped for sealing. If sealing is done by wrapping, only a single strand of PTFE filament can be wound in the opposite direction to tightly wrap the PTFE. Otherwise, when the valve cools down, moisture will enter the valve and freeze.

　　10. Reinstall the valve to ensure that the mating surface is clean and placed correctly.
