- Jan 06, 2019-

The cryogenic storage tank is a two-layer vacuum insulated storage tank. The material selected for the inner tank is austenitic stainless steel; the low temperature storage tank is usually composed of an inner tank, an intermediate heat insulation layer and an outer tank.

1. The inner can is a liquid-tight and flexible inner container made of a thin low-temperature steel plate. Nickel steel, stainless steel or aluminum alloy is usually used.

2. The middle heat insulation layer is filled with inner and outer container interlayers of thermal insulation material pearl sand or aluminum foil, heat insulation cotton and vacuum, the purpose is to isolate internal and external heat conversion.

3. The outer tank is an outer casing that can withstand various loads, and it must have sufficient strength. According to the materials used, it can be divided into the following types: frozen soil wall, steel wall, reinforced concrete wall and prestressed concrete wall.www.wxytgas.com
