Construction temperature polyethylene pipe insulation and actually used up to 150 ℃ to 450 ℃. And the port is the choice of the pipe is generally sealed polyethylene film or a three-layer PE tape wrapped around the cold, but also to prevent the installation or construction before entering the moisture or water. Multi-layer insulation material staggered joint bandage, effectively reducing the heat loss, while the general control measures in the outer surface of the high-temperature steam pipe insulation to prevent cold bridges produce polyurethane insulation pipe manufacturers, but is making the jacket coating some temperature a control has been a great guarantee. And generally with insulation materials to wrap the reflective layer of aluminum foil, multilayer pipe insulation, and thus effectively reducing the heat loss, and the use of steam pipes more reasonable economic performance. 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, significantly reduce energy costs. 2, highly waterproof and corrosion resistance, without attached trench buried hot water pipe insulation, can be directly buried in the ground or water, construction easily and quickly, and lower total cost. 3, at low temperatures also have good corrosion resistance and impact resistance, and can be directly buried underground permafrost. 4, the service life of up to 30 - 50 years, proper installation and use can make the pipe network maintenance costs low. 5, you can set the alarm system, automatic detection of pipeline leakage fault, accurate fault location and automatic alarm indication.
