Armaflex insulation pipe (pipe, tube, tubing, rod) for flexible and lightweight heavy elastomeric nitrile rubber material designed for thermal insulation. Its flexibility makes it suitable for the insulation of a large diameter pipeline overhead. The closed expanded structure provides the ideal and most efficient vapor barrier to prevent condensation or ice build-up on cooling systems, chilled water and refrigerant lines. Armaflex pipes can inhibit LSS heat for hot water and heating pipes, dual temperature pipes and the solar system. It protects the pipes by acting as a vibration damper and provides protection against corrosion by the atmospheric and industrial environment.
