Cold applied tapes are used on a various places. For example, to cover steel pipes, to repair the damaged parts of the pipe coating, on pipe bends and valves.

After the surface of the steel pipe is cleaned from power wire brush or sand blasting, adhesive primer is applied to the surface and Polyken tapes are wrapped tightly.
