Design and safety requirements for high-purity helium gas storage tanks, comprehensive analysis

Helium, high-purity helium

The design and safety requirements of high-purity helium storage tanks are very important, as high-purity helium is a colorless and odorless gas that poses certain risks during storage and use. The following will elaborate on the materials, dimensions, valves, and safety requirements of the storage tank.

Firstly, the material for high-purity helium gas storage tanks should be selected from materials such as stainless steel that have good resistance to the infiltration of high-purity helium gas. Due to the small molecular structure of high-purity helium gas, it is easy to penetrate into the pores of general materials. Stainless steel has good sealing properties and can effectively block the penetration of high-purity helium gas, ensuring the quality of storing high-purity helium gas.

Secondly, the size of high-purity helium storage tanks should be designed according to the needs of storage and use. The capacity of the storage tank should be determined based on the amount and storage time of high-purity helium gas. Generally, the storage tank capacity used is several hundred liters or even several thousand liters. In addition, the shape and size of the storage tank should also consider the convenience of use and space limitations to facilitate the handling and installation of the tank. The selection of valves is also very important in the design of high-purity helium storage tanks. Valves should be made of stainless steel to prevent the infiltration and leakage of high-purity helium gas. In addition, the valve should have good sealing performance and flow control function to facilitate the filling and discharging operation of the storage tank. The operation mode of the valve can be selected as manual operation or automatic control according to actual needs.

The safety requirements for high-purity helium storage tanks mainly include the following aspects: setting up fixed ignition sources and no smoking areas: high-purity helium is a highly flammable and explosive gas, so no smoking signs should be set up near the high-purity helium storage tank to prohibit open flame operations in the area. Equipped with a fire alarm system: In order to promptly detect dangerous situations such as high-purity helium gas leaks and fires, the storage tank area should be equipped with a fire alarm system to ensure its normal operation.

Install leak detection and alarm devices: In order to detect high-purity helium gas leaks in a timely manner, the storage tank should be equipped with a leak detection device that can issue an alarm. The leak detection device can use concentration detectors, air pumps, and other equipment to improve the sensitivity and accuracy of leak detection. Equipping emergency response facilities: Corresponding emergency response facilities should be equipped near the storage tank, such as emergency sprinkler systems, explosion-proof equipment, etc., to cope with emergencies and fires.

Regular inspection and maintenance of storage tanks: To ensure the safety of storage tanks, regular inspections and maintenance should be carried out. The inspection includes the material and sealing performance of the tank body, as well as the normal operation of valves. Maintenance work mainly includes cleaning the tank body, replacing valves and seals.
