Product Details

polyethylene anticorrosion tape is a new member of anti-corrosion anti-corrosion tape system is high-performance polyethylene film as a substrate, both sides at the same time high-pressure thermal composite anti-corrosion butyl rubber belt made of anti-corrosion materials can be cold Wrapped construction, with the construction of convenience, pollution-free and so on, is the preferred anti-corrosion pipeline one of the anti-corrosion system.

Product description:

This anti-corrosion inner belt to overcome the ordinary anti-corrosion with the outer band of small adhesive characteristics, the outer band through the high-performance anti-corrosion butyl rubber and tightly bonded to the inner band, the outer band even if the case To the intense pull will not be separated from the inner belt, thus giving the dual function of take-out protection and anti-corrosion, greatly improving the anti-corrosion effect.


Mainly used in oil and gas transmission; chemical, urban construction, such as water supply and drainage and gas pipeline buried in the external corrosion of steel pipe.
