With the rapid development of modern industry, the demand for pipeline products in chemical, energy and Metallurgical Industries is increasing, and the demand for pipeline products in some special environments is also increasing, many pipeline products have also been developed for specific applications. “Vacuum adiabatic cryogenic tube” is one of the applications in a specific environment of the pipeline products. Vacuum adiabatic cryogenic tube, also known as high vacuum multi-layer adiabatic cryogenic tube, short for (liquid nitrogen vacuum tube) vacuum tube, it is a kind of cold preservation tube, the utility model is composed of an inner pipe, an outer pipe, an adsorbent, a corrugated expansion joint, multi-layer heat insulating materials, supports, etc. .
