For realizing above-mentioned purpose; The technological scheme that the utility model adopts is: the two compound reinforced pipes of a kind of metal and plastics; It is characterized in that: comprise the wire netting frame plastic composite pipe; The outer surface of said wire netting frame plastic composite pipe is provided with the metal oxidation prevention layer; Said metal oxidation prevention layer and said wire netting frame plastic composite pipe adopt linear prestressing techniques compound for one, and said wire netting frame plastic composite pipe is compound through mutual bonding back employing extruding-out process by inner layer plastic tube, outer layer plastic tube and wire netting to be one, and said wire netting is arranged between inner layer plastic tube and the outer layer plastic tube.
The two compound reinforced pipes of above-mentioned metal and plastics, it is characterized in that: said inner layer plastic tube and outer layer plastic tube are Polybutylene Pipe, heat-resisting polyethylene tube or polypropylene random copolymer pipe.
The two compound reinforced pipes of above-mentioned metal and plastics, it is characterized in that: said wire netting is steel wire or stainless (steel) wire.
The two compound reinforced pipes of above-mentioned metal and plastics, it is characterized in that: said metal oxidation prevention layer is aluminium alloy layer or stainless steel lining.
The two compound reinforced pipes of above-mentioned metal and plastics is characterized in that: between said inner layer plastic tube and the wire netting and all mutually bonding through PUR between outer layer plastic tube and the wire netting.
The two compound reinforced pipes of above-mentioned metal and plastics, it is characterized in that: an end of said wire netting frame plastic composite pipe is provided with wire netting frame plastic composite pipe joint.
The two compound reinforced pipes of above-mentioned metal and plastics, it is characterized in that: the two ends of said wire netting frame plastic composite pipe are provided with wire netting frame plastic composite pipe joint.
The two compound reinforced pipes of above-mentioned metal and plastics, it is characterized in that: said wire netting frame plastic composite pipe joint and said wire netting frame plastic composite pipe are one-body molded.
The utility model compared with prior art has the following advantages:
1, simple in structure, reasonable in design; The compound reinforced pipe of this pair comprises the wire netting frame plastic composite pipe; The outer surface of wire netting frame plastic composite pipe is provided with the metal oxidation prevention layer; It is one that metal oxidation prevention layer and wire netting frame plastic composite pipe adopt linear prestressing techniques compound; To adopt extruding-out process compound after bonding be one to the wire netting frame plastic composite pipe through mutual by inner layer plastic tube, outer layer plastic tube and wire netting, and wire netting is arranged between inner layer plastic tube and the outer layer plastic tube.
2, because the linear expansion coeffcient of wire netting frame plastic composite pipe and the linear expansion coeffcient of metal oxidation prevention layer differ less; Be compound in one through linear prestressing force combination process again; Active force each other makes that the linear expansion coeffcient of the two is basic identical, so product structure is stable, in conjunction with seamless; Never layering, and combine reliable and secure.
3, the utility model makes the reinforced pipe mechanical property strengthen greatly through two combination process, and promptly bearing capacity, abrasive resistance and temperature resistant capability are all stronger, and using effect is good.
4, using scope is wide, can be widely used in the industry of high level and superelevation layer and civilian hot and cold water, potable water and the heating system.
Through accompanying drawing and embodiment, the utility model is done further detailed description below.
