Liquefied gas storage tanks are strictly prohibited from overpressure

Install a water leakage prevention device on the up/down valve which connects the water level gauge and the storage tank. If the water level gauge is damaged due to an accident, the upper and lower valves will close automatically.

The cylinder should be placed in a well-ventilated place, and the distance between the fire source, heat source should not be less than 1.5 m.

The calculation of the minimum cross-sectional area of the safety valve exhaust must meet the following requirements. Provide a drain pipe for the safety valve.

Horizontal LPG storage tanks are those in which the long axis of the tank is parallel to the ground and the tank is placed horizontally.

filling job
1. Open all valves in the liquid phase pipe between the liquid outlet and the dispenser. and open all valves in the return pipe.
