It is widely used in central air conditioning, construction, chemical industry, medicine, textile, metallurgy, shipbuilding, automobile, electrical appliances and other related cold and hot medium pipes or containers to reduce cold and heat losses. In addition, the construction is simple, the appearance is neat and beautiful, and the product does not contain fiber dust, and will not breed harmful substances such as mold. Therefore, it is a high-quality new generation of thermal insulation material.

[0003] When the existing rubber-plastic insulation pipe is used, glue is usually applied to both ends of the rubber-plastic insulation pipe to make two adjacent rubber-plastic insulation pipes stick together, and then the gap at the connection is sealed with tape. However, after long-term use, the viscosity of the glue and the tape will decrease, resulting in the connection between the two rubber-plastic insulation pipes not being tight enough, and when the rubber-plastic insulation pipe needs to be removed, it can only be removed by destroying the rubber-plastic insulation pipe, which will produce debris during removal and is inconvenient to clean.

[0004] Therefore, we propose a pressure-resistant rubber-plastic insulation pipe that is easy to connect to solve the above-mentioned problems. Utility Model Content
