Abstract

The utility model pertains to the technical field of conveying pipe, in particular discloses a steel-plastic composite pipe for mines and oil fields. The main technical propose is that, the pipe comprises a metallic pipe body and an anti-corrosion layer coated on the inner wall of the metallic pipe body. As a further improvement of the utility model, the anti-corrosion layer is of polypropylene. The utility model is characterized by the high resistance to corrosion, friction and scaling, the good pressure withstanding property and the long service life. The utility model is widely applicable for mines and oil fields.

Description

Steel-plastic composite pipe
Technical field
The utility model belongs to the pipe technology field, relates in particular to the conveyance conduit of a kind of mine, oil field use.
Background technique
At present, the conveyance conduit of liquid such as conveying crude oil and tailings adopts the high metallic conduit of compressive strength mostly on oil field and mine, but, metallic conduit is corrosion-resistant, rub resistance, good antiscale property poor performance, therefore causes the working life of metallic conduit short, and cost of production improves relatively.Conveyance conduit is corrosion-resistant in order to improve, rub resistance, good antiscale property performance, brings into use the conveyance conduit of being made by materials such as polyvinyl plasticss.But this conveyance conduit compressive strength is low, uses plastic pipe in the occasion that pressure is big slightly, breaks the danger that causes liquid to reveal easily.
The model utility content
Problem to be solved in the utility model just provides the steel-plastic composite pipe of a kind of corrosion-resistant, rub resistance, good antiscale property, good pressure-resistant performance, long service life.
For addressing the above problem, the technical solution adopted in the utility model is: the metal body is coated with corrosion-resistant coating at described metal body internal face.
Its additional technical feature is: described corrosion-resistant coating is a polypropylene material; The thickness of described corrosion-resistant coating is the 1-6 millimeter.
Steel-plastic composite pipe provided by the utility model compared with prior art has the following advantages: one, owing to be coated with corrosion-resistant coating, improved corrosion-resistant, rub resistance, good antiscale property performance at metal body internal face, and prolonged working life; Its two because corrosion-resistant coating is that thickness is the polypropylene material of 1-6 millimeter, both guaranteed corrosion-resistant, rub resistance, good antiscale property performance, prevented coming off of corrosion-resistant coating again.
Description of drawings
Accompanying drawing is the structural representation in the utility model steel-plastic composite pipe cross section.
Embodiment
Be described in further details below in conjunction with the concrete structure and the use principle of accompanying drawing the utility model steel-plastic composite pipe.
As shown in drawings, the utility model steel-plastic composite pipe comprises metal body 1, be coated with the corrosion-resistant coating 2 of polypropylene material at metal body 1 internal face, the thickness of corrosion-resistant coating 2 preferably is set to the 1-6 millimeter, like this, both guarantee corrosion-resistant, rub resistance, good antiscale property performance, prevented coming off of corrosion-resistant coating again.
Certainly corrosion-resistant coating 2 also can be made for other materials with corrosion-resistant, rub resistance, good antiscale property performance.

Claims (3)

1, steel-plastic composite pipe comprises the metal body, it is characterized in that: be coated with corrosion-resistant coating at described metal body internal face.
2, steel-plastic composite pipe according to claim 1 is characterized in that: described corrosion-resistant coating is a polypropylene material.
3, steel-plastic composite pipe according to claim 1 and 2 is characterized in that: the thickness of described corrosion-resistant coating is the 1-6 millimeter.
