Model utility content
In order to solve the technical problem existed in background technique, the utility model proposes a kind of draining composite pipe, the good and corrosion resistance excellent of its anti-pressure ability, and serviceability is good.
A kind of draining composite pipe that the utility model proposes, comprise inner plastic, the first elasitic layer, metal layer, the second elasitic layer and plastic outer layer, from inside to outside, inner plastic, the first elasitic layer, metal layer, the second elasitic layer, plastic outer layer are socketed successively, metal layer is made up of layers of copper and aluminium lamination from inside to outside, and the outer surface of layers of copper and aluminium lamination internal surface have the first concaveconvex structure and the second concaveconvex structure that cooperatively interact.
Preferably, the first concaveconvex structure is formed by many grooves being distributed in layers of copper outer surface, and the second concaveconvex structure is formed by many fins being distributed in aluminium lamination internal surface.
Preferably, every bar groove has multiple cavity, and every bar fin has multiple convex ridge, cooperatively interact what often organize cavity and convex ridge is triangle or trapezoidal or stepped shaft along composite pipe radial cross section.
Preferably, the first concaveconvex structure convexes to form by being distributed in the multiple of layers of copper outer surface, and the second concaveconvex structure is formed by the multiple pits being distributed in aluminium lamination internal surface.
Preferably, the protruding and pit of the often group cooperatively interacted be triangle or trapezoidal or stepped shaft along composite pipe radial cross section.
Preferably, the first elasitic layer thickness: metal layer thickness: the second elasitic layer thickness is (0.03-0.05): 1:(0.01-0.03).
In above-mentioned draining composite pipe, inner plastic and plastic outer layer can provide good corrosion resistance for the internal surface of composite pipe and outer surface, metal layer makes the mechanical strength of composite pipe get a promotion, and the first elasitic layer, the second elasitic layer can promote the binding ability between inner plastic and metal layer, between metal layer and plastic outer layer under thermal expansion repeatedly respectively; Metal layer is adopted layers of copper and aluminium lamination composition, can by the cooperation of aluminium lamination and layers of copper, on maintenance composite pipe mechanical property basis, reduce weight and the cost of whole composite pipe, at the outer surface of layers of copper and aluminium lamination internal surface, the first concaveconvex structure and the second concaveconvex structure that cooperatively interact are set, composite pipe can be made under arms in process, under liquid in pipe washes away, between layers of copper and aluminium lamination, anti-axial stripping ability is improved, thus make not easily to loosen between layers of copper and aluminium lamination, promote the serviceability of composite pipe; Therefore, the good and corrosion resistance excellent of the anti-pressure ability of composite pipe can be made, and serviceability is good.
