Things to pay attention to when using aluminum-plastic pipes for floor heating pipes: floor heating will generally reduce 70-100mm, so before the transformation, it is necessary to fully consider reducing the impact on future life; the selected pipes should have the test report and product insurance policy issued by the national department. , At the same time, check whether the specifications and dimensions of the pipes are qualified, and whether the appearance is smooth and bright. Remember not to buy inferior pipes, which will leave hidden dangers for future heating; the benzene board should choose materials with low thermal conductivity, flame retardant or non-combustibility, and sufficient bearing capacity. And it should not contain bacterial sources, odors and volatiles that may endanger health; according to relevant standards, benzene boards with thermal conductivity ≤0.041W/m.k, apparent density ≥20.0kg/m3 should be selected, and the combustion classification should reach B2 level; diversity The inner and outer surfaces of the water device (including connectors, etc.) should be smooth and clean, and there should be no cracks, blisters, cold partitions, slag inclusions, uneven uneven defects; the surface electroplated connectors should be uniform in color, firm in coating, and free from deplating defects; The material is preferably copper, and the water separator with temperature control valve is better; due to the high temperature of the supply and return water of the radiator system, in order to ensure the service life of the pipe and avoid the phenomenon of excessive ground temperature and discomfort, it should be used. The small heat exchanger converts the temperature of the water supply, and then calculates and determines the spacing of the pipes according to the specific decoration situation. It is appropriate to keep 100mm---350mm; Strict attention should be paid not to damage the floor heating pipes during construction, and it is forbidden to scrape the outer wall of the pipes with a shovel, trample or press the paved floor heating pipes; the construction of the filling layer should be completed at least 21 days before heating, and the first heating can only be done after the ground is completely dry naturally. .
