The invention relates to the field of pipe fitting processing, and particularly relates to a foam composite pipe production line. The foam composite pipe production line comprises an inner pipe production line, a foam pipe host machine, an outer pipe host machine and a composite die, wherein the composite die comprises a first composite die and a second composite die; a first composite chamber isformed in the first composite die; a second composite chamber which communicates with the first composite chamber is formed in the second composite die; a head of the foam pipe host computer communicates with the first composite chamber; a head of the outer pipe host machine communicates with the second composite chamber; and the inside diameter of the first composite chamber is less than that ofthe second composite chamber. The foam composite pipe production line is high in production efficiency, and a produced foam composite is stable in quality.
Description
technical field [0001] The invention relates to the field of pipe processing, in particular to a foam composite pipe production line. Background technique [0002] The traditional pipeline insulation is to coat a layer of insulation material on the outer surface of the pipe, and then fix the insulation material. This method requires many types of materials to be prepared, and the construction is complicated. When the project volume is large, the construction is extremely cumbersome. In order to solve the above problems, people develop foam composite pipes, such as the Chinese patent authorization announcement number CN 201382211 U, which is called "a kind of plastic foam composite pipe fittings". The foam composite pipe includes an inner pipe, an outer pipe and an inner pipe and The foam pipe between the outer pipes has thermal insulation properties, so it can solve the above problems, but the current foam composite pipe production line is not mature enough, resulting in low...
