Embodiment Construction
[0025] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0026] combine Figure 1 to Figure 5 As shown, the composite pipe of the present invention is schematically shown, including a protective layer 1, an insulating layer 2 and a pipe body 3. The pipe body 3 is formed by spiral crimping and splicing of plates 32, and the pipe body 3 is made of metal material. The pipe body 3 is provided with a connecting rib 31 located at the joint of the plates 32 and spirally arranged around the axis of the pipe body 3 . The connecting rib 31 can increase the rigidity of the pipe body 3 . The insulation layer 2 is spirally attached to the outer wall of the pipe body 3, and the insulation layer 2 is located between two adjacent connecting ri...

The invention relates to the field of pipe structures, in particular to a compound pipe. The pipe body of the compound pipe is formed by spiral and curled jointing of a plate. Spiral-arranged connecting ribs are arranged in jointed positions of the plate in the pipe body. Rigidity of the pipe body can be elevated by the connecting ribs. A thermal insulation layer is spirally attached to the outerwall surface of the pipe body and located between every two adjacent connecting ribs. A protective layer is in a pipe-shape structure and arranged outside the pipe body in a sleeving manner so that the connecting ribs and the thermal insulation layer are cladded. The pipe body can be protected by the protective layer so that the outdoor use weather-proof property of the compound pipe can be improved; besides, compared with an existing spiral air pipe, the outer wall surface of the compound pipe can also become smoother through the protective layer of the compound pipe; while the thermal insulation layer is adopted as an interlayer material between the pipe body and the protective layer, the thermal insulation property and the sound insulation property of the compound pipe can be improved;and meanwhile, space between every two adjacent connecting ribs is also utilized fully.
Description
technical field [0001] The invention relates to the field of pipe structures, in particular to a composite pipe and a production method thereof. Background technique [0002] The spiral air duct is a thin-walled pipe made of a spiral bite with a metal strip, and is generally used for air supply, oil fume exhaust, dust removal or bulk material transportation. High rigidity, not easy to deform or break. However, due to the thin wall of the spiral air duct, its thermal insulation, weather resistance and sound insulation performance are weak, and because the spiral air duct adopts a mechanical occlusal process, there are still very small leakage gaps in the pipe body. The production process of the tube body cannot further improve its scope of application. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide a composite pipe and its production method, so as to solve the problems of weak thermal insulation, ...
