Dewar bottle

Content

Welded insulated gas cylinders (hereinafter referred to as gas cylinders) have a double-layer structure, with an insulating layer between the inner liner and the outer shell. The insulating layer is equipped with multiple layers of insulating material and maintains a high vacuum, and is used for the transport and storage of deep cold liquids such as liquid nitrogen and liquid oxygen.
The cylinder range is divided into low pressure, high pressure and ultra-high pressure according to the set pressure of the safety valve, and vertical and horizontal according to the type. Vertical cylinders have a nominal volume of 110L, 175L, 195L, 210L, 236L, 455L, 500L, 800L and 1000L respectively, while horizontal cylinders have a nominal volume of 410L and 499L respectively. The cylinders are easy to use, safe and reliable, economical and durable.
