1. Heating equipment is used in winter in northern my country, and the average temperature is low. It is a kind of heat exchange between air and heat source through heat source and heat medium, thereby increasing the room temperature. The heating equipment commonly used in the north is plumbing. The original design requirement is that the water pipes will freeze in places where the temperature is lower than 0 degrees Celsius in winter. Simply put, heating is an ancillary service, the need for water by city dwellers.
2. PPR is a kind of high toughness, high strength, high processing yield, high temperature creep resistance, high transparency and so on. Widely used in the manufacture of pipes, sheets, daily necessities, packaging materials, home appliance parts, various types of films, etc. PP-R pipe, also known as three-type polypropylene pipe, random copolymerized polypropylene, is a random copolymerized polypropylene extrusion pipe, which can also be injection molded.
3. PB pipes are high molecular weight inert polymers. PB resin is a polymer complex synthesized from 1-butene as a raw material. It is a crystal with a special density (0.937) and a flexible heterogeneous body. It is a high-tech product belonging to the category of organic chemical materials. It has high temperature resistance, durability, chemical stability and plasticity, it is odorless, non-toxic and tasteless.
