The invention relates to a β-PPR pipe and its processing method, which comprises a protective layer, a middle layer and a core layer. Grooves are formed on the inner surface of the middle layer, and graphene modifiers are filled in the grooves. As a large-size lamellar material, graphene possesses excellent physical and chemical properties. Its lamellar structure endows the pipe with good barrier performance and weather resistance. A low dosage of graphene can also effectively improve tensile strength and other mechanical properties of pipe materials.
