Corrosion pipe insulation refers to a steel pipe to ensure that the working temperature and the surface temperature in different work environments while slowing or chemical outside the media under insulation corrosion protection electrochemical action or by the metabolic activity of microorganisms and prevent erosion and deterioration . Corrosion pipe insulation performance advantages: 1, good insulation properties, heat loss is only 25% of the traditional pipe, long run can save a lot of energy buried black jacket pipe insulation, significantly reduce energy costs. High density polyethylene polyurethane foam insulation tubes: a certain corrosion resistance, and has good insulation properties. Selection of second degree inorganic zinc primer (temperature ≥400 ℃) anti-corrosion coatings, pipes port selection polyethylene film or three PE cold sealing tapes, insulation material multi-layer bandaging wrong seam, effectively reducing the heat loss black jacket insulation pipe manufacturers, while using surface controls polyurethane coat black jacket pipe insulation, so that the temperature control jacket coating is guaranteed. It features: low heat loss and save energy. Corrosion, good insulation properties, long service life.
