| Advantages
|
1. The heat-insulating material has the advantages of light, durability, excellent heat preservation performance, low heat consumption and maximum utilization of heat energy. 2. Vacuum extraction technology can be used to effectively prevent the corrosion of internal and external steel pipes. 3. Special material heat insulation is adopted between the sliding bracket and the steel pipe to effectively solve the heat bridge problem in the pipe network, and the heat loss of the pipeline is reduced |
