Abstract
The invention relates to a multilayered structure and multifunction pipeline and a connecting device, solving the disadvantages of poor corrosion resistance, poor crushing resistance, poor heat-insulating property, no shapely appearance, high production cost, single structure, and the like of the existing pipelines. The pipeline comprises a corrosion resistance layer, a crushing resistance layer, a heat-insulating layer and a bacteria resistance layer, and can be of the types of single corrosion resistance and crushing resistance, bacteria resistance, corrosion resistance and crushing resistance and heat-insulating, corrosion resistance and crushing resistance. The invention has the advantages of favorable corrosion resistance, high crushing resistance, favorable heat-insulating property, bacteria resistance, simple installation and connection, reduced production and installation cost, diversified structural type of pipeline and connecting device, and the like. The pipeline can be used for drinking water supply projects, drainage engineering, oil transportation, corrosive liquid transportation, high temperature liquid and gas transportation, etc.
Description
Technical field: [0001] Multi-layer structure multi-functional pipeline and connecting device, which reduces the corrosion defect of pipelines and joints, and increases the service life of pipelines and joints. Increase the pressure resistance of pipes and joints. It also has a bactericidal effect. The production and installation costs of pipelines are reduced. Adds to the aesthetics of the pipeline. Pipes for insulation can also increase the insulation of the pipes. It is used in drinking water projects, oil pipelines, drainage pipes, corrosive liquid transportation and other fields. technical background: [0002] Most of the pipelines and joints on the market are simple galvanized iron pipes and simple plastic products. Because the pipelines are buried underground and exposed to the air for a long time, simple metal iron products are easy to oxidize and get rusty. The service life of the pipeline is greatly reduced, and a lot of manpower will be wasted for maintenance...
