METHOD FOR PROTECTING PIPELINES AGAINST CORROSION

摘要

The invention provides for the protection of pipelines and other metal surfaces from corrosion. The metal surface is coated with a vulcanizable elastomeric polyorganosiloxane coating re-inforced with geo-tech fabric or any other similar nature fabric or sheeting materials. In a preferred embodiment the geo-tech reinforced silicone provides both cathodic and corrosion protection in submersible underground and overground pipelines. The present invention also provides for a method of protecting exposed surfaces particularly metal surfaces more particularly, metal pipelines from the effects of a corrosive environment. The method comprises applying to the surface a thin layer of a vulcanizable elastomeric polyorganosiloxane rubber composition, applying geo-tech or similar fabric onto the wet surface; optionally applying a second application of the same or different vulcanizable elastomeric polyorganosiloxane rubber composition and allowing the composition to cure to a silicone elastomer.
