Lingyuan sells heat capacity tubes there.

Liaoning Li Hao Pipe Industry Co., Ltd. produces and sells plastic products, plastic profiles, plastic colored tiles, building pipes and fittings, PVC pipes and fittings, pe pipes and fittings according to the inquiry of Aiqi official website. The hot-melt water pipe adopts PPR pipe, which is very popular in the market. Its full name is random polypropylene, commonly known as type III polypropylene. Hot-melt water pipes are welded to water pipes and their fittings with a hot-melt machine at high temperature, which is more compact and safer than the traditional PVC glue connection method, and the price of the hot-melt machine is also cheaper. The disadvantage is that once welded, it is more troublesome to take it off.
