Description

Technical Field

[0001] The utility model relates to the technical field of steel-plastic composite pipes, in particular to a steel-plastic composite pipe with enhanced compression resistance. Background Art

[0002] Steel-plastic composite pipe is a new type of pipe. Due to its unique structure, it has good compressive resistance. Its compressive resistance mainly comes from the following aspects: Structural design: Steel-plastic composite pipe is usually composed of an inner layer of plastic and an outer layer of steel. The plastic layer provides good corrosion resistance, while the steel layer provides strong mechanical strength and load-bearing capacity. This composite structure can disperse and withstand external pressure more effectively. Material properties: The combination of the high strength of steel and the flexibility of plastic enables the steel-plastic composite pipe to withstand pressure without brittle fracture, but to withstand a certain amount of deformation. Manufacturing process: Through reasonable manufacturing processes, such as hot pressing, cold processing, etc., the mechanical properties of the composite pipe can be further improved, making it perform better in terms of pressure resistance. Connection method: Using reasonable connection methods (such as welding, flanges, etc.) during installation can effectively improve the compressive resistance of the overall system.

[0003] When existing steel-plastic composite pipes need protection, they usually need to be covered with a suitable cylindrical flexible protective cover. During the covering process, the protective cover is easily stuck on the outside of the steel-plastic composite pipe, and the protective cover cannot be quickly and smoothly covered on the outside of the steel-plastic composite pipe. In addition, the existing flexible protective cover is easily scratched and has poor protective performance. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figures 1-4The figure shows a steel-plastic composite pipe with enhanced compressive resistance, comprising an outer pipe 2, a flexible spiral sleeve 4 wrapped around the outer side of the outer pipe 2, a spiral reinforcement pipe 3 installed in the flexible spiral sleeve 4, and a first flexible spiral edge 5 and a second flexible spiral edge 6 fixedly connected to the left and right sides of the flexible spiral sleeve 4 respectively. The bottom of the second flexible spiral edge 6 is coated with an adhesive layer 7 and the bottom of the adhesive layer 7 is connected to a release paper 8. The spiral reinforcement pipe 3 is made of a metal material with better toughness. The steel-plastic composite pipe with enhanced compressive resistance disclosed by the utility model is outer-coated with a spiral protective sleeve, and a bendable metal spiral reinforcement pipe 3 with better toughness is also inserted in the spiral protective sleeve, which has good protective performance and can be installed quickly.

[0020] Furthermore, the outer tube 2 is fixedly connected to the inner tube 1, the inner tube 1 is a plastic tube, and the plastic layer provides good corrosion resistance; further, the outer tube 2 is a steel tube, and the steel layer provides strong mechanical strength and bearing capacity; further, the flexible spiral sleeve 4, the first flexible spiral edge 5 and the second flexible spiral edge 6 are all made of flexible rubber material; further, the flexible spiral sleeve 4, the first flexible spiral edge 5 and the second flexible spiral edge 6 are all made of foamed silicone material; further, the cross-section of the spiral reinforcement tube 3 is semicircular with the arc surface facing outward, and the protection effect is good.

[0021] In this solution, when in use, the steel-plastic composite pipe with enhanced compressive resistance disclosed by the utility model is covered with a spiral protective sleeve, and a bendable metal spiral reinforcement pipe 3 with better toughness is also inserted into the spiral protective sleeve, which has good protective performance and can be installed quickly. The head of the spiral protective sleeve is attached to the outside of the steel-plastic composite pipe that needs to be covered, so that the spiral protective sleeve composed of the spiral reinforcement pipe 3, the flexible spiral sleeve 4, the first flexible spiral edge 5 and the second flexible spiral edge 6 is covered on the outside of the steel-plastic composite pipe, so that the second flexible spiral edge 6 is pressed on the adjacent first flexible spiral edge 5. After covering, slowly tear off the release paper 8 from the beginning, so that the second flexible spiral edge 6 is glued to the adjacent first flexible spiral edge 5 through the adhesive layer 7. Since the flexible spiral sleeve 4, the first flexible spiral edge 5 and the second flexible spiral edge 6 are all made of flexible material, they are scratch-proof and cut-proof. The spiral reinforcement pipe 3 is made of metal material with better toughness. The cross-section of the spiral reinforcement pipe 3 is semicircular with the arc surface facing outward, which plays the role of the skeleton of the spiral protective sleeve, can prevent collision to a certain extent, and has good protective performance.
