Abstract
The utility model discloses a steel-plastic composite pipe provided with a cladding type sealing structure. The steel-plastic composite pipe provided with the cladding type sealing structure comprises a pipe body (1) which is provided with the end faces (4) and the inner wall (7), cladding layers made of PE are arranged on the end faces, the cladding layers are provided with outer cladding layers (3) connected with the outer wall of the pipe, end face cladding layers (5) connected with the pipe end faces, and inner cladding layers (6) connected with the pipe inner wall, the inner cladding layers are of thin-wall-type arcs, the cladding layers can seal the outer wall, the end faces and the inner wall of the pipe body in a continuous cladding mode. According to the steel-plastic composite pipe provided with the cladding type sealing structure, the outer wall, the end faces and the inner wall are all sealed by the cladding layers, the butt fusion area of the cladding layers and the pipe is increased, the butt fusion strength and the butt fusion reliability are high, media can not enter a gap between a steel framework and plastic from the pipe end faces, therefore using requirements of the steel-plastic composite pipe can be guaranteed, and safety of the pipe is improved.
Description
Technical field
The utility model relates to pipeline, especially relates to steel-plastic composite pipe.
Background technique
As everyone knows, steel-plastic composite pipe is the novel tube that a kind of thermoplastic inside is filled with Steel Skeleton, it compare with existing other tubing not only have in light weight, intensity is high, resistance to acids and bases is strong, and the heat resistanceheat resistant sex change is good, shock-resistant, long service life, safe and reliable characteristics.Therefore, steel-plastic composite pipe has obtained using widely in industry pipework such as chemical industry, municipal administration, oil, combustion gas.All be filled with Steel Skeleton in the steel-plastic composite pipe, Steel Skeleton need seal processing on the tube end face and be exposed at outward, with Steel Skeleton sealing, seals in from the Steel Skeleton of tube end face jointing and the slit between the plastics to prevent medium, guarantees that tubing uses safety.The steel-plastic composite pipe sealed port of butt end is handled and is mostly adopted the sealing of pipe end face at present, this end face seal structure has following point: because pipe material inner wall is thinner, effective welding area of end face seal parts and tubing internal layer end face is limited, heat seal strength and reliability are lower, be affected by thermal expansion and contraction, skeleton in the tube wall can produce thrust by opposite end face seal portion part, cause end face seal parts and inner tube layer end face weld the crack to occur, cause end face seal to lose efficacy, medium seal in Steel Skeleton and plastics in conjunction with in the slit, influence the use safety of tubing.
The model utility content
At the low-quality problem of steel-plastic composite pipe sealed port of butt end in the above-mentioned prior art, the utility model provides a kind of tube end face seal quality the good steel-plastic composite pipe that has interior clad type seal structure.
The technological scheme that the technical problems to be solved in the utility model is taked is: the described clad type that has seals knot
The steel-plastic composite pipe of structure comprises the tubing body, described tubing body has end face and inwall, described end face is provided with the clad made from PE, described clad has the external coating that links to each other with outer pipe wall, the end face clad that links to each other with tube end face and the internal coating that links to each other with pipe material inner wall, described internal coating is the circular arc of thin wall-type, and described clad can realize coating continuously sealing with outer wall, end face and the inwall of tubing body respectively.
It is all hermetically enclosed by outer wall, end face and inwall that the described steel-plastic composite pipe end face of the utility model patent is wrapped by layer, improved the welding area of clad and tubing, heat seal strength and reliability height, medium can not enter into slit between Steel Skeleton and the plastics from tube end face, thereby can guarantee the steel-plastic composite pipe usage requirement, improve the Security of tubing.
Description of drawings
Fig. 1 is sectional structure schematic representation of the present utility model.
Embodiment
In Fig. 1, the described steel-plastic composite pipe that has the clad type seal structure comprises the tubing body 1 that is filled with Steel Skeleton 2 in it, described tubing body has end face 4 and inwall 7, described end face is provided with the clad made from PE, described clad has the external coating 3 that links to each other with outer pipe wall, the end face clad 5 that links to each other with tube end face and the internal coating 6 that links to each other with inwall 7, the shape and size of described external coating are determined according to the Connecting format of tubing, internal coating is connected with the tubing body by inwall, described clad can with the outer wall of tubing body, end face and inwall realize coating continuously sealing.Described external coating, end face clad and internal coating form an integral body by the injection moulding mode, the inner end of described internal coating (end that links to each other with the tubing nose end) is the circular arc of thin wall-type, the circular arc maximum ga(u)ge size of described internal coating can guarantee that tube end face does not leak, guaranteeing again looses core smoothly moves back mould, and described internal coating outer end links to each other with the end face clad.
Claims (1)
1. the steel-plastic composite pipe that has the clad type seal structure, it comprises tubing body (1), described tubing body has end face (4) and inwall (7), described end face is provided with the clad made from PE, it is characterized in that: described clad has external coating (3), the end face clad (5) that links to each other with tube end face and the internal coating that links to each other with inwall (6) that links to each other with outer pipe wall, described internal coating is the circular arc of thin wall-type, and described clad can realize coating continuously sealing with outer wall, end face and the inwall of tubing body.
