Abstract
The utility model provides a composite pipe of metallic plastic, including a metal pipe layer, a plastic pipe layer, a caking agent layer and an outer covering layer outside of the metal pipe layer. The composite pipe of metallic plastic has a strong double-faced corrosion protection ability, long service life, good insulating property and more reliable and safer use.
Description
The utility model relates to a kind of building pipe, particularly a kind of composite metal-plastic pipe.
The present building pipe that is applied to water supply and sewage generally is a Coating Steel Pipe, but this tubing is on the verge of being replaced owing to there is more shortcoming, therefore need seek a kind of novel tubing replaces this traditional Coating Steel Pipe, a kind of plastic stainless-steel composite-tubes is disclosed in the patent No. is 99220392.9 model utility, this composite pipe is that the plastic tube with outer field Stainless Steel Tube and internal layer is combined with each other by Bond, the hard characteristics of light and metal tube with plastic tube, may be used on the occasion of water supply and sewage, but this plastic stainless-steel composite-tubes exists than significant disadvantages: outer field stainless steel is exposed in the air, be vulnerable to the corrosion of chemical substance and reduction of service life, in addition because the stainless steel electric conductivity is better, so when this composite pipe uses following time of environment in humidity, if also comparatively dangerous when having the situation of electric leakage to take place, cause accident easily.
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, provide a kind of can be two-sided preferably anticorrosion and composite metal-plastic pipe with good insulation performance.
This metal plastic composite pipe comprises metal tube layer, plastic pipe layer, adhesive layer, also is included in the outer outer cover of metal tube layer.
Described outer cover is the good plastic pellicles of insulating property.
The utility model has following advantage with respect to prior art: because the outermost surface of this metal plastic composite pipe also is processed with outer cover, thereby can avoid the metal tube layer of composite pipe directly to contact with extraneous, so not only can avoid of the corrosion of extraneous chemical substance preferably to the metal tube layer, prolong the working life of this metal plastic composite pipe, and outer cover also can play insulation to the metal tube layer, the accident that prevents to leak electricity takes place, and uses safer; What this metal plastic composite pipe also possessed the common metal plastic composite pipe in addition has that plastic tube is light, heat preservation and insulation good and metal tube is hard, advantages of high strength concurrently, so also can be widely used in industries such as building, food, health, chemical industry, heating, home decoration.
Below in conjunction with embodiment's accompanying drawing the utility model composite metal-plastic pipe is described in further detail.
Fig. 1 is the structural representation of this metal plastic composite pipe.
Embodiment:
Fig. 1 shows the concrete structure of this metal plastic composite pipe, as seen from Figure 1, this metal plastic composite pipe is made of four construction layers such as plastic pipe layer 1, adhesive layer 2, metal tube layer 3, outer covers 4, outer cover 4 is positioned at the outermost of this metal plastic composite pipe, closely be coated on metal tube layer 3 outside, material is the good plastic pellicles of insulating property, plastic pipe layer 1 is positioned at the inboard of metal tube layer 3, has adhesive layer 2 that metal tube layer 3 and plastic pipe layer 1 are bonded together between metal tube layer 3 and plastic pipe layer 1.The material of the metal tube layer 3 of this metal plastic composite pipe can adopt metals such as Ordinary Steel, stainless steel or aluminium, and the raw material of plastic pipe layer 1 and outer cover 4 can adopt plastics such as polyethylene, and Bond can adopt hot melt adhesive.
Claims (2)
1, a kind of composite metal-plastic pipe comprises metal tube layer (3), plastic pipe layer (1), adhesive layer (2), it is characterized in that: also be included in the outer outer cover (4) of metal tube layer (3).
2, antibacterial metal plastic composite pipe according to claim 1 is characterized in that: described outer cover (4) is the good plastic pellicle of insulating property.
