Aluminum-plastic pipes can be connected to heating, but there are certain advantages and disadvantages, which need to be understood in advance. First of all, this kind of aluminum-plastic pipe has beautiful appearance and smooth inner wall, because the middle is aluminum and the outer layer is plastic. It is easy to bend during construction, which reduces the construction difficulty. However, this kind of pipeline is prone to joint leakage and is more susceptible to thermal expansion and contraction, so its aging resistance is not particularly good and it is easy to deform after repeated operation.
How to choose the heating pipe?
1, heating equipment is used in winter in northern China, and the average temperature is low. It is a kind of heat exchange between air and heat source through heat source and heat medium, thus improving room temperature. The common heating equipment in the north is water heating. The original design requirement is that when the temperature is below 0 degrees Celsius in winter, the water pipes will freeze. In short, heating is an auxiliary service, that is, the demand of urban residents for water.
2.PPR is characterized by high toughness, high strength, high processing yield, high temperature creep resistance and high transparency. Widely used in manufacturing pipes, sheets, daily necessities, packaging materials, home appliance parts, various films, etc. PP-R pipe, also known as type III polypropylene pipe and random polypropylene, is a kind of random polypropylene extruded pipe and can also be injection molded.
3. Polymer inert polymer for lead pipe. PB resin is a polymer complex synthesized from 1- butene. It is a kind of crystal with special density (0.937) and a flexible heterostructure. Belonging to high-tech products of organic chemical materials. It has high temperature resistance, durability, chemical stability and plasticity, and is odorless, nontoxic and odorless.
