Abstract

The invention relates to a pipeline and a manufacturing technology thereof, in particular to a multifunctional composite pipe capable of delivering different media simultaneously and a manufacturing process used for manufacturing the composite pipe. The composite pipe comprises wires, a pipe body and a wrapping layer. The wires are parallel to the pipe body. The outer portions of the wires and the outer portion of the pipe body are provided with the wrapping layer in a seamless mode. The wrapping layer is made of high-polymer materials. The core of the composite pipe and the forming process of the composite pipe is that the outer portions of the wires and the outer portion of the pipe body are covered with the high-polymer materials in a molten state, and the physical properties of the wires and the pipe body keep unchanged in the manufacturing process; the relative positions of the wires and the pipe body are maintained through the high-polymer materials, so the composite pipe has good strength and stability.

Description

Technical field [0001] The invention relates to a pipeline and its manufacturing technology, and more specifically, to a multifunctional composite pipe capable of simultaneously transmitting different media and a manufacturing process applied to manufacture the composite pipe. Background technique [0002] Hose reel is also called winder, reel, reel and drum. It is widely used in people's daily life and work. Because of its many functions, it is also called water drum, electric drum, and air drum according to the functions. When in use, it can be pulled out as much as needed, and the hose reel can be automatically retracted after use, so as to avoid piles of scattered wires or empty pipes that are prone to accidents and pipeline damage. Maintenance factories that do not use wire winders are dangerous for energy pipelines. Pipelines that have been dragged on the ground in the past are very susceptible to damage from strong corrosive materials. At the same time, workers’ unintent...
