Water pipes will freeze, as long as the local temperature is low enough and there is no reliable antifreeze measures, the water in the water pipes will freeze. When water freezes, it will expand, and general metal pipes such as galvanized pipes, due to their poor tensile properties at low temperatures, are often frozen and cracked, which affects their use and causes accidents. The PPR water pipe is a plastic part, which has poor heat transfer ability and has a certain antifreeze ability. Compared with iron pipes, it is more difficult to freeze, and in the case of freezing, it is not easy to freeze due to its certain tensile strength. PPR is the abbreviation of English random copolymer polypropylene (Polypropylene-Random). Commonly known as three-type polypropylene.
