The utility model belongs to the technical field of plastics tubular product technique and specifically relates to a compound pipe and pipeline are moulded to steel is related to. Plant the steel andmould compound pipe, include: the body, the body includes inlayer, skin and intermediate level, the inlayer with the skin passes through the intermediate level is compound, the both ends of body are provided with the joint respectively, connect with the body is through the integrated into one piece that moulds plastics, adjacent two pass through between the body the articulate. It is higher in order to alleviate the adjacent plastic steel composite pipe connection degree of difficulty that exists among the prior art, and the junction also is the relatively low technical problem of holding capacity.
