These are high technology corrosion proofing systems, composed of thermoshrinking tubular tires made of a very thin polyolephinic electronically-irradiated compound and a putty having very good adhesiveness and dielectric strength. Their use on Gas and Water pipelines simplifies and considerably quickens the covering application. Their excellent resistance to salts, acids, alkalis, different oils, greases and solvents, as well as a good resistance to UV rays, place these products among the best in the field of passive protection of any metallic material to be laid underground. APPROVED: DVGW.

Clean well the surface to be treated. Preheat with a flame up to 40 –50°C, insert the tubular tire and extract any possible silicone film. Start to heat the pipe circle and the joint external part with regular movements, making sure that no pockets or wrinkles form. When a little quantity of putty comes out, it means that total thermoshrinkage has occurred.
