Froststop Pipe Inside is the heating section based on selflimiting heating cable that maintains the required temperature of the pipeline during the whole cold season thus ensuring its good performance, uninterrupted operation and safe condition.

Froststop Pipe Inside section is primary designed for use in case when you are not able to install the heating cable directly on the pipe surface or the pipe is already buried at a depth above the frostline.

Froststop Pipe Inside section is installed inside the pipe filled with water or other non-agressive substance. The section can be also installed outside the pipeline.

The heating section consists of a segment of self-limiting cable equipped with 3-meter cold lead with electric plug at one end and with end termination coupling at the other end. For the section entry into the pipe gland assembly is included in the kit.

The factory made connection and end termination couplings are reliable and tightly sealed.

Electric power is applied from one end of the section. At the far end of the heating segment the end termination coupling is installed that is located inside the pipe and ensures ingress protection rating IP68. For the section entry into the pipe a gland assembly is used consisting of two bushings, two washers and rubber sealing ring.
