Liquid Gas Cylinder Hydrogen Cryogenic Storage Tank
Description
(1) The tank body adopts high vacuum winding insulation design and assisted by special high vacuum maintenance technology, with good insulation effect and less Ig evaporation;
(2) The tank body is designed with large diameter and low vertical transportation height to ensure product performance and save transportation cost;
(3) Compact structure, small floor area, fast and convenient installation, which can be easily installed and used on the same day of arrival;
(4) Compared with the traditional gas supply mode of storage tank + vaporization pressure regulating skid, the cost is better;
(5) flowmeter and remote monitoring can be installed to realize digital and information management.

1) Tank body: a pressure vessel consisting of an inner container, an outer shell and a thermal insulation layer.
2), the inner container (the material is generally stainless steel): the inner tank that stores cryogenic liquid and can withstand working pressure. Generally include: cylinder, head, craft manhole, external pressure reinforcement ring, etc.
3) Shell (generally made of carbon steel or low alloy steel): an airtight container that forms and protects the vacuum insulation space. Generally, it includes: cylinder body, head, external pressure reinforcement ring, lead pipe through-wall joint, lifting lug, support, etc.
4) Interlayer: refers to the closed space formed between the inner container and the outer shell. Generally, it includes: thermal insulation material (vacuum powder-pearl sand), inner container and outer shell connecting support member, and evacuated flow pipe.
5) The pipeline system generally includes: safety discharge and vent pipe, differential pressure liquid level gauge lead pipe, full liquid indicator pipe (overflow pipe), liquid inlet pipe, supercharger liquid inlet, air outlet pipe, pumping pipe. vacuum tube, etc.
