Abstract
The invention belongs to the technical field of composite tubes and particularly relates to a metal plastic composite tube and a machining method thereof. The metal plastic composite tube comprises a plastic inner layer tube body, a metal layer and a plastic outer coating. The metal layer is arranged outside the plastic inner layer tube body. The plastic outer coating is arranged outside the metal layer. Due to the plastic inner layer tube body and the plastic outer coating, the weight of the composite tube is light, the plastic inner layer tube body has the corrosion-resistant function, and the metal layer has the functions of resisting high heat and high pressure. The metal plastic composite tube is light in weight and capable of resisting the high heat, the high pressure and corrosion.
Description
Technical field
The invention belongs to the composite pipe technical field, relate in particular to a kind of composite metal-plastic pipe and processing method thereof.
Background technique
Traditional composite metal-plastic pipe more adopts internal plastic coating or lining to mould and covers the processing method of moulding outward, such composite pipe just be take the metal layer function as main, install and connect on metal layer, plastic layer is just born various protective actions, and adopt the outer plastic layer that covers that the processing method connected is installed, fail again to stop the infiltration of peeling off of metal and plastics junction.
The pipeline of a lot of application needs Nai Gaore and high pressure now, simultaneously also lightweight, as: the larger specification building internal riser of solar water delivery pipe (requiring Nai Gaore and high pressure), heating and production delivery, pipe, high voltage bearing mining nonmetallic pipe (also requiring lightweight) etc. for hot water central heating secondary pipe network.More and more application are more and more higher to the requirement of pipeline, and a lot of application at present need pipeline, and both ability was high hot, high pressure resistant and corrosion-resistant, and the weight of pipe also wants light simultaneously, and common single pipe can not meet these demands.
