The structure of the Cryogenic Storage Tank

The storage tank and supercharger consist of integrated components that allow the supply of liquid or gas without the need for external power, ensuring the purity of the discharged liquid or gas. Additionally, they are equipped with a pressure conditioning installation, enabling users to adjust the conditioning valve (T) to achieve the desired pressure for liquid discharge. This ensures stable pressure and convenient operation. The storage tank also features a liquid filling joint for tank cars, facilitating the transfer of liquid to vaporizers and tank cars.

The tank is equipped with top and bottom liquid inlet pipelines, which can realize pressure difference and low temperature liquid pump unloading and filling;

The liquid outlet of the storage tank can supply gas directly or enter the cryogenic pump for external gas supply;

The storage tank is equipped with gas-phase pipelines, which can realize gas discharge, safe release, pressurization and gas return after pumping;

The storage tank is equipped with an overflow pipeline to avoid overfilling when unloading and filling;

The storage tank is equipped with double safety valves (or rupture discs) to discharge when overpressure to protect the safety of the inner container;

The storage tank is equipped with a pressure gauge to display the internal pressure in real time, which should be checked regularly according to regulations;

The storage tank is equipped with a liquid level meter to display the internal medium stock, which is used for reference and not for measurement;

The tank is equipped with vacuumizing and measuring vacuum pipelines to ensure the insulation performance of interlayer;

The tank is equipped with shell explosion-proof device to discharge gas in case of leakage of inner container to avoid serious damage and danger;

The interlayer of storage tank is high vacuum multi-layer winding insulation, which has small volume, good insulation effect.

Note: the parameters of safety valve shall not be changed at will and shall be calibrated regularly, otherwise it will cause safety accidents.

Production Process:

The circumferential welds of tanks are overlapped, and the longitudinal welds are butt welded. The ring plates are arranged alternately, taking the odd number to make the end cap diameter the same. Our products adopt high vacuum multi-layer winding technology. Better thermal insulation performance and longer vacuum service life.

Advantages：

Horizontal Cryogenic Tanks for LNG Storage provide secure, safe and cost-efficient solutions for storing large volumes of liquid natural gas (LNG). LNG is stored as a cryogenic liquid at temperatures as low as -163°C. Horizontal tanks are widely used in LNG storage applications because they offer better pressure control and a lower center of gravity than vertical tanks, resulting in increased stability and safety.

Horizontal tanks can be tailored to the specific application and site conditions, allowing customers to optimize their storage capabilities. These tanks are available in a range of sizes and can be used for both short-term and long-term storage. The typical capacities of these tanks range from 50,000-250,000 gallons.

Horizontal tanks are designed with double-walled, vacuum-insulated walls, creating a safe and secure environment for the stored LNG. The primary tank is constructed from high-grade pressure vessel steel, while the inner tank is made of stainless steel. Both tanks are surrounded by a multi-layered insulation system, reducing loss to the environment and allowing for efficient operation.

Horizontal tanks feature specialized safety systems and are designed to meet all relevant global requirements. These tanks include high integrity pressure protection systems, flame arrestors, pressure relief valve, and other safety features to minimize the risk of spillage or explosion.

Horizontal tanks are also extremely durable. The exterior of the tanks are typically coated with a corrosion-resistant paint in order to prevent the tank from developing any structural damage over time. In addition, these tanks are designed to last for decades, ensuring reliable long-term storage for businesses.

Installing horizontal tanks for LNG storage offers companies several advantages. Installation requires minimal site preparation, with only a single access platform needed to set up the tank, a great cost-saving measure. Additionally, horizontal tanks require less space, allowing businesses to optimize the site area. Horizontal tanks also require minimal maintenance, making it easy to operate and monitor the stored LNG levels.

Overall, horizontal tanks for LNG storage provide businesses with Cost-efficient, secure and safe solutions for the long-term storage of large volumes of LNG. By capitalizing on their reduced installation time and space requirements, horizontal tanks allow companies to utilize their available space more efficiently. Moreover, these tanks are designed with multiple safety features and enhanced durability, ensuring businesses enjoy years of reliable operation.
