Product Advantages
Excellent Performance

The insulated pipe is made of NBR and PVC. It doesn't contain fibrous dust, benzaldehyde and chlorofluorocarbons. Moreover, it has low conductivity & heat conductivity, good moisture resistance, and fireproof.

Widely Used

The insulated pipe can be widely used in cooling unit and equipment of central air conditioning, freezing water pipe, condensing water pipe, air ducts, hot-water pipe and so on.

Easy Installation

The insulated pipe not only can be easily installed with the new pipeline, but also can be used in the existing pipeline. The only thing you need to do is to cut it, then glue it. Moreover, it doesn't have negative influence on the performance of the insulated pipe.

Complete Models
