High vacuum multi-layer insulation cryogenic Piping, short for vacuum insulation Piping (VI Piping) , or vacuum jacket Piping (VJ Piping) , is the perfect substitute of traditional insulation Piping. Compared with the traditional insulation pipe, the heat leakage value of vacuum insulation pipe is only 0.05 ~ 0.035 times of the traditional insulation pipe. Can Save a lot of energy and cost for customers
