Stainless steel is applied for both inner/outer tubes; Can keep high vacuum situation for long term  

High-vacuum/multilayer insulation cryogenic liquid transfer piping is designed as dedicated pipeline for cryogenic liquid transfer

As for the vacuum pipe, stainless steel is applied for both inner/outer tubes; High Vacuum dedicated multilayer insulation and counter radiation composite are used inside the interlayer

Applying vacuum flange connection technology and special leak proof structure, the pipe is able to keep high vacuum situation for long term. Thus, coldness loss is minimized.
