Polyethylene pipe insulation pipe part: Mechanisms of a barrier, reflective layer: to ensure that organic foam material does not enter the hard inorganic refractory layer; a reflective layer portion of high temperature heat. 2, inorganic rigid insulation layer: high temperature heat pipe insulation to ensure the interface between temperature and the organic insulating layer, to ensure not to be carbonized foam. 3, drag reduction layer: to ensure the free movement of expansion and contraction pipe work. 4, steel work: to ensure the normal flow of the transmission medium. 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, anti-corrosion pipe insulation insulation properties, heat loss is only 25% of traditional pipe, long run can save a lot of energy, significantly reduce energy costs.
