The test pieces shall be subjected to high-voltage continuity testing prior to this test. For testing, the polyethylene layer may be applied without adhesive to make sampling easier.


How to know the Quality Guarantee: The system consists of liquid epoxy base coat, hot-melt adhesive and base from meshed high-density polyethylene.

The peel strength requirements have been adapted to the production methods commonly used today. Coating pipe is the pipe that is by the processing after the corrosion, which can effectively prevent or slow the steel pipe occurs in the course of transport and chemical or electrochemical reaction corrosion phenomena. If there is a spark, mark the defective area.
