Abstract
The utility model relates to a composite pipe material, and particularly relates to a steel-plastic composite pipe, and resolves the problem that gap may appear between the steel pipe and the plastic layer after long time use of steel plastic composite pipe. The steel plastic composite pipe includes a steel pipe and plastic layer fixed on the surface, wherein the steel pipe has a rough surface. The steel plastic composite pipe provided by the utility model reinforces the adhering performance between the steel pipe and the plastic layer by executing improvement of the steel-pipe construction, thereby improving anti-corrosion capability of the steel plastic composite pipe, preventing accumulated filth at the inner wall of the steel pipe, decreasing fluid resistance with good mechanical intensity, and is suitable for fields of mine, petroleum, chemical industry, municipal administration, construction, etc.
Description
Technical field
The utility model relates to composite pipe, is specially a kind of steel-plastic composite pipe.
Background technique
Composite pipe especially steel-plastic composite pipe because its good anti-corrosion and have shock resistance and tensile strength is big etc. that advantage is widely used in industry and mining and the daily life, yet continuous increase along with service time, steel pipe and and the fixing plastic layer of steel tube surface between be prone to the slit, thereby cause the corrosion of steel-plastic composite pipe, reduction of service life.
Summary of the invention
The utility model uses back steel pipe and plastic layer to be prone to the problem in slit in order to solve existing steel-plastic composite pipe for a long time, and a kind of steel-plastic composite pipe is provided.
The utility model is to adopt following technological scheme to realize: steel-plastic composite pipe, comprise steel pipe and the plastic layer of fixing with its surface, and described steel pipe is the steel pipe of surface irregularity.Because steel tube surface is uneven, like this plastic layer and steel pipe fixedly the time adhesion property improve greatly, avoided steel-plastic composite pipe to use afterwards steel pipe and plastic layer to be prone to the problem in slit for a long time.
Plastic layer is polyethylene layer, polypropylene layer, polyvinyl chloride layer or PVC layer, has further strengthened the protection to steel-plastic composite pipe in the time of the physical and chemical performance of reinforced plastic layer.
Steel-plastic composite pipe described in the utility model is by improving the adhesion property that has strengthened steel pipe and plastic layer to steel-pipe construction, thereby improved the anti-corrosion capacity of steel-plastic composite pipe, prevent steel pipe inwall incrustation, reduce fluid resistance, have excellent mechanical intensity, be applicable to fields such as mine, oil, chemical industry, municipal administration, building.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1-steel pipe, 2-plastic layer.
Embodiment
Steel-plastic composite pipe comprises steel pipe 1 and the plastic layer of fixing with its surface 2, and described steel pipe 1 is the steel pipe of surface irregularity.Plastic layer 2 is polyethylene layer, polypropylene layer, polyvinyl chloride layer or PVC layer.In the specific implementation process, steel pipe 1 is put into pre-control equipment, thereby form pit not of uniform size, that the depth is different with rigid steel ball bump steel pipe 1 surface that varies in size, then plastic layer 2 is fixed on the surface of steel pipe 1, make steel-plastic composite pipe described in the utility model.
Claims (2)
1. a steel-plastic composite pipe comprises steel pipe (1) and the plastic layer of fixing with its surface (2), and it is characterized in that: described steel pipe (1) is the steel pipe of surface irregularity.
2. steel-plastic composite pipe according to claim 1 is characterized in that: plastic layer (2) is polyethylene layer, polypropylene layer, polyvinyl chloride layer or PVC layer.
