Abstract
The steel-plastic composite pipe with cementing layer is formed from steel pipe and plastic pipe, and is characterized by that between the steel pipe and plastic pipe a cementing layer is set. The utility model has the advantages that the steel pipe and the plastic pipe in the steel-plastic composite pipe are firmly adhered together by the cementing layer, thereby avoiding the axial displacement between the steel pipe and the plastic pipe and keeping good use performance.
Description
The utility model relates to the steel-plastic composite pipe with antisepsis.
Steel-plastic composite pipe is to be composited by steel pipe, plastic tube, is widely used in carrying in the engineering of corrosive gas, liquid.Though steel pipe has certain magnitude of interference with cooperating of plastic tube, but because the coefficient of thermal expansion and contraction of steel and plastics is made a world of difference, make steel pipe and plastic tube in the steel-plastic composite pipe produce axial displacement, have a strong impact on the usability of steel-plastic composite pipe, particularly the jointing at two steel-plastic composite pipes produces careless mistake, causes the leakage of corrosivity gas, liquid.
The purpose of this utility model is to provide a kind of steel-plastic composite pipe with glued film in order to overcome above-mentioned deficiency, and under the big situation of the temperature difference, steel pipe in the steel-plastic composite pipe and plastic tube can not produce axial displacement yet, keep good usability.
Description of the present utility model is as follows: have the steel-plastic composite pipe of glued film, skin is a steel pipe, and internal layer is a plastic tube, is glued film between steel pipe and plastic tube, and glued film is cemented in steel pipe with plastic tube.
Description of drawings:
Figure is the sectional view with steel-plastic composite pipe of glued film of the present utility model.1-steel pipe among the figure, 2-glued film, 3-plastic tube.
Embodiment makes like this: have the steel-plastic composite pipe of glued film, skin is steel pipe (1), and internal layer is plastic tube (3), is glued film (2) between steel pipe (1) and plastic tube (3), and glued film (2) adopts HA type copolymer primer.
The utility model advantage: with the gummed layer steel pipe in the steel-plastics composite pipe and plastic tube are cemented in together, Avoid the axial displacement between steel pipe and the plastic tube, kept good serviceability.
Claims (2)
1, the steel-plastic composite pipe that has glued film is made up of steel pipe and plastic tube, it is characterized in that between steel pipe and plastic tube it being glued film.
2, the steel-plastic composite pipe with glued film according to claim 1 is characterized in that glued film is a HA type copolymer primer.
