Abstract
The utility model discloses a steel-plastic composite pipe, which relates to a composite piping. The steel-plastic composite pipe comprises a plastic pipe and a steel pipe which is installed on the outer wall of the plastic pipe, wherein a surge-changing-resistant reinforced layer is arranged between the plastic pipe and the steel pipe, a reinforced rib which is integrally formed with the steel pipe is arranged on the outer wall of the steel pipe, both ends of the steel pipe are respectively provided with a flange, and both the outer surface of the flange and the outer surface of the steel pipe are respectively provided with a plastic layer. The surge-changing-resistant reinforced layer is arranged between the plastic pipe and the steel pipe, so that the thermal surge resistance and the strength are improved, and the delamination phenomenon can be avoided; the flanges are fixedly arranged on two ends of the steel pipe, so that the quick connection between two adjacent steel pipes can be realized through the threaded connection between the adjacent flanges in the application process, and the labor intensity can be alleviated; the plastic layers are arranged on the outer wall of the flange and the outer wall of the steel pipe, so that the problems of the traditional steel-plastic pipe such as easiness in corrosion and rustiness and no electrostatic resistance and no flame resistance can be overcome; and the reinforced rib is arranged on the outer wall of the steel pipe, so that the fusion welding area and the fusion welding strength of the plastic layers can be enhanced.
Description
Technical field
The utility model relates to a kind of composite pipe, relates in particular to a kind of steel-plastic composite pipe.
Background technique
At present, steel-plastic composite pipe is with its good anti-corrosion and have advantages such as shock resistance, tensile strength be big and be widely used in chemical industry, mining industry and the daily life.Existing steel-plastic composite pipe generally is made up of plastic inner pipe and stainless steel outer tube, and it is bonding to mould compound adhesive through special-purpose steel between the two.Yet, because the heat of fed sheet of a media springs up, after long-term the use, break away from each other easily between plastic inner pipe and the stainless steel outer tube, shortened working life, using to people makes troubles.In addition, existing steel-plastic composite pipe in use need be through being weldingly connected, and labor intensity is bigger; And, since the material of steel itself and under special conditions of manufacture, exist perishable, be prone to get rusty, do not possess antistatic, anti-flame retardant property, have serious potential safety hazard.
The model utility content
To the problem that above-mentioned existing technology exists, the utility model purpose is to provide a kind of steel-plastic composite pipe, can effectively solve the problem that exists in the above-mentioned existing technology.
The technological scheme of the utility model is: a kind of steel-plastic composite pipe; Comprise plastic tube and be installed in the steel pipe of plastic tube outer wall; Be provided with the anti-change enhancement layer that gushes between plastic tube and the steel pipe; Be provided with integrated with it strengthening rib at outer wall of steel pipe, and all be fixed with flange, be equipped with plastic layer on the outer surface of said flange and steel pipe at the steel pipe two ends.
As preferably, said anti-gushing becomes enhancement layer and is made up of plastics and packing material.
As preferably, said packing material comprises shortwave fiber, calcium carbonate masterbatch, stabilizer and auxiliary chemicals.
As preferably, the height of said plastic layer is greater than the height of strengthening rib.
As preferably, said plastic layer is polyethylene layer, polypropylene layer, polyvinyl chloride layer or PVC layer.
Compared with prior art, the beneficial effect of the utility model is following:
1) between plastic tube and steel pipe, is provided with and anti-gushes the change enhancement layer, improved heat resistanceheat resistant and gushed performance and intensity, avoided delamination, prolonged working life;
2) set firmly flange at the steel pipe two ends, in the using process, can realize the quick connection between adjacent steel pipe, reduced labor intensity through being threaded between adjacent flanges, time saving and energy saving;
3) establish plastic layer at the outer wall of flange and steel pipe, overcome that existing steel moulds that tubing exists perishable, be prone to get rusty and do not possess problem antistatic, anti-flame retarding;
4) outer wall at steel pipe is provided with strengthening rib, has increased the face of weld and the heat seal strength of plastic layer, has avoided occurring in the using process situation that plastic layer peels off or splits.
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
As shown in Figure 1; A kind of steel-plastic composite pipe; Comprise plastic tube 1 and be installed in the steel pipe 3 of plastic tube 1 outer wall, be provided with anti-gushing between plastic tube 1 and the steel pipe 3 and become enhancement layer 2, be provided with integrated with it strengthening rib 4 at steel pipe 3 outer walls; And all be fixed with flange 5 at steel pipe 3 two ends, be equipped with plastic layer 6 on the outer surface of said flange 5 and steel pipe 3.The said anti-change enhancement layer 2 that gushes is made up of plastics and packing material.Said packing material comprises shortwave fiber, calcium carbonate masterbatch, stabilizer and auxiliary chemicals.The height of said plastic layer 6 is greater than the height of strengthening rib 4.Said plastic layer 6 is polyethylene layer, polypropylene layer, polyvinyl chloride layer or PVC layer.
The utility model is provided with anti-gushing and becomes enhancement layer 2 between plastic tube 1 and steel pipe 3, and adds packing material, and its thermal expansion coefficient and steel pipe 3 are more approaching, have improved heat resistanceheat resistant and have gushed performance and intensity, have avoided delamination, have prolonged working life.
The utility model sets firmly flange 5 at steel pipe 3 two ends; And flange 5 is welded on the two ends outer wall of steel pipe 3; One end face of flange 5 is concordant with the end face of steel pipe 3, in the using process, can realize the quick connection of 3 of adjacent steel pipes through being threaded of 5 of adjacent flanges; Reduced labor intensity, time saving and energy saving.
The utility model is established plastic layer 6 at the outer wall of flange 5 and steel pipe 3, overcome that existing steel moulds that tubing exists perishable, be prone to get rusty and do not possess problem antistatic, anti-flame retarding; And plastic layer 6 is chloroacrylate layer, pvdc layer, polyvinyl chloride layer or tetrafluoroethylene layer, during use, can select the plastic layer 6 of respective material according to the difference of external environment for use.
The utility model is provided with strengthening rib 4 at the outer wall of steel pipe 3, has increased the face of weld and the heat seal strength of plastic layer 6, has avoided occurring in the using process situation that plastic layer 6 peels off or splits.
