The more widely used heating pipes are PPR and PB, which have very good low temperature resistance and high performance, and can be thermally welded. There are also aluminum alloy-lined plastic pipes, but they are usually not used much. Now, PPR tube is the main choice for heating tube.
1. The currently installed heating pipes generally use aluminum alloy lined plastic pipes, PPR pipes, PB pipes and PERT pipes, which are more suitable than the original galvanized pipes.
1. The aluminum alloy lined plastic pipe and the heating joint are connected by copper pipe fittings. Because the expansion coefficient is the same as the expansion coefficient of the buried surface, the entire pipeline must be able to maintain a connected state and avoid water leakage, which will cause maintenance problems.
2. PPR pipe PB pipe adopts a hot-melt connection method to make the same type of pipe fully integrated. The connection type is more suitable for hidden burial and external forces, and the possibility of water leakage is 0.
3. The galvanized pipe is more complicated than the connection structure. The heating position must be replaced by a pipe. The hot water should be equipped with a closing gate to prevent leakage, and the valve should be closed to reduce losses. Notify the sales service department and door repair and enter. The standard heat dissipation of the heating pipes connected to the same side is based on the measured heating pipe heat;
2. The degree of connection on the opposite side of the heating pipe is more suitable to ensure the uniform temperature distribution of the overall effect of the radiator, and the heat dissipation is basically the same as the above;
3. Since the average temperature of the heating pipe surface is reduced, the connection on the same side and the connection on the opposite side are reduced, which reduces the benefit of concealing the pipe in the inner wall of the wall.
4. In addition, the indoor heating pipes are heated faster in series connection than in parallel. The disadvantage is that the temperature of the heating terminal is low, and the pipe must be modified and designed before heating.
PPR pipe PB pipe which kind of pipe is suitable for heating pipe, I believe that everyone has an answer to this after reading this article. Just remember that during the critical period of winter heating equipment maintenance and maintenance, in addition to preparing aluminum alloy-lined plastic pipes for heating, other heating pipes must be tested and maintained to prevent the heating budget from reaching the predetermined testing measures.
