How is the Pipeline for Cryogenic Liquid Tank Designed?

Aug. 30, 2019

The cryogenic storage tank equipment is used to store special gases such as liquid oxygen, liquid nitrogen, liquid hydrogen, liquid helium, and liquid fluorine, so there are many special treatments in the design of the container, such as piping design. Knowing the structure of the equipment can help you better use the equipment. Today Cryogenic Tank Supplier will explain how the piping of the cryogenic tank equipment is designed.

The cryogenic liquid inlet and outlet pipes, the vent pipe, the sewage pipe, the instrument pipe, and other necessary pipes shall be arranged on the low-temperature storage tank equipment. In design, in order to reduce the heat transfer capacity of the pipeline, in addition to materials with low thermal conductivity, the manufacturer will reduce the number of pipelines as much as possible while satisfying the requirements of operation, flow rate, and working pressure. Smaller, the wall is as thin as possible. However, the amount of gas to be transmitted will be less, so the length of the pipe will be designed to be longer, and the length of one section in the non-thermal layer should be as much as one meter or more.

The two ends of the pipe of Cryogenic Liquid Tank are welded to the inner casing and the outer casing respectively. When used, the equipment will have a pre-cooling work. When the working temperature is reached, the parts will shrink to different degrees, so the pipe should be bent in the no-heat layer. U-shaped, ring-shaped or spiral, or a telescopic joint in place, to have a large expansion and contraction capacity.

The container size for Cryogenic Storage Tank China equipment is based on the designed capacity. When the diameter of the cylindrical container is equal to the length, it is close to the spherical container, and the high-pressure container has a larger aspect ratio.
