Why can Vacuum Insulated Tubing be used in geothermal well? In recent years, global climate has deteriorated, global warming, and countries such as Northern Europe (Sweden, Norway, Finland, Denmark, Iceland) have begun to develop non-fossil energy sources such as geothermal, solar, and wind energy. In Northern Europe, there are often
Vacuum insulated tubing & casing uses water-based fiber cloth material with a three grade vacuum pump equipment,automatic welding machine and MT. These guarantees a high degree of vacuum level that meets the insulation grades D and E. These vacuum insulated tubing & casing use an effective getter to ensure the tubing
