Abstract
The utility model relates to a stainless-steel aluminum-plastic composite pipe, which comprises an aluminum-plastic composite pipe which is formed from that plastic pipes are respectively stuck on the inner wall and the outer wall of an aluminum or aluminum alloy pipe. A stainless steel pipe is close sheathed on the outer wall of the aluminum-plastic composite pipe. The stainless-steel aluminum-plastic composite pipe not only has water resistance, acid and alkali resistance, corrosion resistance, beautiful and flowery appearance, and good mechanical intensity. The stainless-steel aluminum-plastic composite pipe an ideal transport pipeline of water supply, heating, gas supply, and liquid in industrial and civil fields.
Description
The utility model relates to a kind of stainless steel aluminium-plastic composite pipe, and it can be widely used as and be oil, chemical industry and other industry, gas, liquid are carried in the civilian industry water supply, hot duct.
Along with improving constantly of industrial development and living standards of the people, the pipeline of carrying changes in temperature gas, water and liquid is had higher requirement, in recent years, various metal composite pipes are come out one after another, modal and use amount maximum to be aluminium-plastic composite pipe, its not only in light weight and acid-and base-resisting, anticorrosive, but this plastic-aluminum pipe mechanical strength is poor, and easily aging.Another kind of modified model metallo-plastic pipe, for example the patent No. is " 96242528 " " metallo-plastic anti-corrosion pipe ", though energy acid-and base-resisting, mechanical strength is good, but this composite pipe is not easy bending, especially under the situation of expanding with heat and contract with cold, plastic shrink, the phenomenon that can cause plastic tube and metal tube to be separated, thus make liquid infiltrate metal inner surface from pipe joint, cause the metal tube corrosion.
The purpose of this utility model is to provide a kind of novel stainless steel aluminium-plastic composite pipe at the defective of above-mentioned prior art to society.
Task of the present utility model is achieved in that this stainless steel aluminium-plastic composite pipe, comprises the aluminium-plastic composite pipe that is stained with plastics on the inside and outside wall of aluminum or aluminum alloy pipe respectively, the close Stainless Steel Tube that is with on the outer wall of this aluminium-plastic composite pipe; Between Stainless Steel Tube and aluminium-plastic composite pipe, be stained with polyurethane foam material.
The utility model stainless steel aluminium-plastic composite pipe, close cover Stainless Steel Tube had both had the aluminium-plastic composite pipe softness on traditional aluminium-plastic composite pipe outer wall, water-fast, acid-and base-resisting, the anticorrosive premium properties that waits, it is magnificent attractive in appearance to have stainless steel again, the advantage that mechanical strength is good.Between Stainless Steel Tube and aluminium-plastic composite pipe, add one deck polyurethane foam plastics, can improve the thermal insulation property of this composite pipe greatly, when carrying heating installation, hot water, can improve the heat energy utilization rate greatly.
Accompanying drawing is a kind of embodiment of the present utility model.
Below in conjunction with accompanying drawing, the utility model will be further described.
Shown in the accompanying drawing, after being welded into aluminum pipe 4 by the aluminium skin, and on inside and outside wall, coat hot melt adhesive, in extruder, extrude and cooling shaping with plastics, make by the aluminium-plastic composite pipe of plastic tube in being compounded with on aluminum pipe 4 inside and outside walls 5 and outer plastic tube 3 plastic tube 3 outside, coat polyurethane 2 materials or hot melt adhesive then, be inserted in that to carry out extrusion stretching in the Stainless Steel Tube 1 compound, this Stainless Steel Tube 1 can be welded by stainless steel sheet.At last, and cut, make the stainless steel aluminium-plastic composite pipe of different size according to the different length needs.
Claims (2)
1. stainless steel aluminium composite pipe, it comprises the aluminium-plastic composite pipe that is stained with plastic tube (3), (5) on the inside and outside wall of aluminum pipe or Al-alloy pipe (4) respectively, it is characterized in that the close Stainless Steel Tube (1) that is with on the outer wall of this aluminium-plastic composite pipe.
2, stainless steel aluminium-plastic composite pipe according to claim 1 is characterized in that being stained with polyurethane (2) foam material between the inwall of the outer wall of described aluminium-plastic composite pipe and Stainless Steel Tube (1).
