The system can be directly installed under the temperature as low as -110℃ on all piping equipment. When the surface temperature of the pipe is lower than -100℃ and the pipeline usually has obvious repeated movement or vibration, it is necessary to lay a layer of wear-resistant film on the inner surface to further strengthen the inner wall strength of the material to ensure the long-term adiabatic effect of frequent movement and vibration of the process pipeline under deep cooling.
