How to Use Polyurethane Thermal Insulation Pipe
1. To reduce the cost of construction, double-control heating pipeline can reduce the cost of construction by 25% (using FRP as maintenance layer) and 10% (using high density polyethylene as maintenance layer) under normal conditions.
2. Low heat loss and waste of power. The thermal conductivity of polyurethane insulating pipe is much lower than that of other commonly used pipelines, and its thermal insulation effect is increased by 4-9 times. And its water absorption is very low, about 0.2 kg/m2. The reason for low water absorption is that the polyurethane foam has a closed porosity of about 92%. Low thermal conductivity and low water absorption, together with insulation layer and waterproof high density polyethylene or FRP maintenance shell, have changed the situation of traditional trench laying heating pipeline "wearing wet cotton jacket", greatly increased the overall heat loss of heating pipeline, heat loss of heating network is 2%, less than the world standard requirements of 10%.
3. Polyurethane insulating steel pipe has anticorrosion, good insulation function and long service life. The directly buried insulation pipe is tightly adhered to the outer skin of the steel pipe because of the rigid polyurethane foam insulation layer, which blocks the entry of air and water, and can play an excellent anti-corrosive effect. At the same time, the foam holes of the prefabricated directly buried insulating pipe are closed, and the water absorption is very small. High density polyethylene shell, FRP and PU insulating steel tube shell all have excellent anti-corrosion, insulation and mechanical functions. Therefore, the task steel pipe skin is very comfortable to the outside air and water corrosion. According to foreign data, the service life of polyurethane insulation pipe and polyurethane insulation pipe can reach more than 50 years, which is 3-4 times longer than that of traditional trench laying. Overhead laying service life of directly buried insulation pipe manufacturer is 3-4 times longer than that of traditional trench laying.
4. Foreign consumer polyurethane insulating steel pipes and directly buried insulating pipe manufacturers all have leakage alarm lines. Once leakage occurs somewhere in the pipeline, it is transmitted by the alarm lines. In order to inform the inspectors to deal with the leaking pipeline quickly and ensure the safe operation of the heating network, the exact position and the size of the leaking pipeline can be displayed on the public inspection instrument.
