The invention discloses a construction method of a composite pipe delivery line. The composite pipe delivery line comprises composite pipelines and a connector, and each composite pipeline comprises acarbon steel pipe and a stainless steel pipe; and the connector comprises two connecting housings and a sealing sleeve, and a ring washer is arranged on the inner wall of the sealing sleeve. The construction method comprises the steps that the carbon steel pipe is arranged at the exterior of the stainless steel pipe in a sleeving mode, and then the ends of the carbon steel pipe and the stainlesssteel pipe are welded together to form the composite pipelines; the ends of the two composite pipelines are in butt joint together, and the outer side of the connecting portion formed between the twocomposite pipelines is wrapped by the sealing sleeve; the ring washer is tightly clamped between the ends of the two composite pipelines, and the ring washer covers the welding portion formed betweenthe carbon steel pipe and the stainless steel pipe; and the two connecting housings are buckled together, and used for wrapping the connecting portion between the two composite pipelines, and ribs areclamped in locating grooves in the corresponding sides. The corrosion resistance of the composite pipe delivery line is improved, so that the service life of the composite pipe delivery line is prolonged.
Description
technical field [0001] The invention relates to the field of mechanical technology, in particular to a construction method for a composite pipe delivery pipeline. Background technique [0002] The transmission pipeline is widely used as a transmission tool for long-distance transportation of liquid or gas. The transmission pipeline is formed by connecting multiple steel pipes, and the two steel pipes are connected by connectors. For example: Chinese Patent No. 201920749835.5 discloses a transmission pipeline, which includes a plurality of steel pipes, and two adjacent steel pipes are connected by pipe connectors. In actual use, since the delivery pipeline is used for long-distance delivery of emulsion, after a long period of use, it will cause corrosion on the inner wall of the steel pipe, resulting in a decrease in service life. How to design a transmission pipeline technology with long service life is the technical problem to be solved by the present invention. Contents...
