NOVELTY - The utility model claims a composite PE water supply pipe, comprising an outer layer, an inner layer and an outer layer; between the inner layer is provided with a buffer layer made of elastic material; between the buffer layer and the outer layer is provided with a graphene layer; between the buffer layer and the inner layer is provided with a steel wire layer; the steel wire layer is a hollow circular ring formed by sealing the upper steel wire layer and the lower steel wire layer woven by steel wire around the water supply pipe. The utility model is provided with a graphene layer to improve the toughness of the water supply pipe; the set steel wire layer improves the strength of the water supply pipe; the supporting column added in the steel wire layer further improves the strength; Through the structure set above, improves the toughness and strength of the water supply pipe, so as to better solve the PE water supply pipe in the use process is easy to break problem, avoid the resource waste caused by water leakage.
