Technical Field

[0001] The utility model relates to the technical field of rubber-plastic pipes, in particular to a flexible high-molecular low-temperature deep-cold rubber-plastic pipe. Background Art

[0002] Cryogenic rubber-plastic pipe is a pipe made of cryogenic rubber-plastic. Cryogenic rubber-plastic is a special material with excellent performance. The "cryogenic" here means that it can maintain good elasticity and softness at extremely low temperatures. Cryogenic rubber-plastic is usually composed of synthetic rubber, nanomaterials, etc., and has good heat resistance, good cold resistance and good oxygen barrier properties.

[0003] The cryogenic rubber-plastic pipe has a poor protective effect during actual use. After being hit, it will be damaged and leak, which will affect the service life of the cryogenic rubber-plastic pipe. For this reason, we propose flexible polymer low-temperature cryogenic rubber-plastic pipe. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are: the flexible polymer low-temperature deep-cold rubber-plastic pipe has the following advantages:

[0014] 1.
