Horizontal natural gas low-temperature storage tank quality assurance 30 cubic LNG storage tank factory price

Description :

　　When planning LNG storage tanks, full consideration should be given to the potential hazards of LNG leakage or spillage during storage and loading/unloading to personnel and major equipment. In the event of a leakage in an LNG storage tank, facilities should be installed around the tank and in the loading and unloading area to prevent the flow and diffusion of LNG in all directions, which helps to minimize the harm caused by LNG leakage. For small LNG storage tanks, a common method is to set up barriers around the tank, such as embankments, retaining walls, or storage pits. For valves and joints that may cause leaks, baffles should be installed to prevent LNG injection; A collection tray should be set up below to collect leaked LNG and introduce it into the storage pit through the discharge pipe. When LNG overflows or leaks, it can be concentrated in embankments, retaining walls, or storage pits to prevent LNG from flowing around. For large LNG storage tanks, they should be built underground to keep the liquid level below ground level.

　　The storage capacity of embankments, retaining walls, or storage pits should mainly be considered based on the capacity of the storage tank, while also taking into account the influence of winter snow or other factors. Therefore, they should have a certain margin in their storage capacity. The storage capacity should be greater than the total volume of LNG when the storage tank is fully loaded.

　　The internal pressure of LNG storage tanks needs to be controlled within the allowable range. Excessive pressure or negative pressure inside the tank can pose a potential danger to the tank. The following measures can be taken to control the pressure of LNG storage tanks:

　　①Install a pressure control device inside the tank to ensure that the pressure inside the tank is within the allowable range;

　　②Install sufficient pressure safety valves and vacuum safety valves. Pressure safety valves can prevent tank overpressure, while vacuum safety valves can sense the local atmospheric pressure to determine if there is a vacuum inside the tank and prevent negative pressure in the tank;

　　③A manually operated shut-off valve should also be installed between the pressure safety valve and vacuum safety valve and the tank body for the maintenance of the safety valve;

　　④Try to ensure that the safety exhaust system can still safely discharge in case of a fire.
