Armaflex insulation pipe (pipes, tubes, tubing, bars) for light weight elastomeric nitrile rubber materials 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 heat retard LSS for hot water pipes and heating, dual temperature pipes and solar systems. It protects the pipe by acting as a vibration damper and provides protection against corrosion by the atmospheric and industrial environment.
