Electric heating steel pipe composite thermal insulation plastic pipe device

Abstract

The invention discloses an electric heating steel pipe composite thermal insulation plastic pipe device. Two pipes which tightly wrap around the outer wall of a steel pipe are installed together in asleeving mode, at least one positioning support rib which is symmetrically and uniformly distributed at intervals is arranged between the two pipes, and thus, thermal insulation of a pipeline is achieved through an electric insulation air interlayer thermal insulation plastic pipe. An electric heating steel pipe gives out heat after being powered on, a control element can control the power of a low-voltage intelligent temperature control power source, little electric energy is used, and water in a pipeline is kept to be at a certain temperature; the inner wall of the pipeline is electrically heated safely and quickly along a metallic conductor to rapidly and uniformly melt ice, a liquid runner is formed, thus, hot water in the pipeline flows downwards along the whole pipeline to quickly melt the ice, and heat generated by wires can maintain that the thermal insulation pipeline is not frozen; and in addition, through the intelligent temperature control power source, the effect that thewater in the pipeline is kept to be at a certain temperature can be achieved, and the function that hot water is discharged by opening a water nozzle can be achieved. The production technology is mature and simple, the strength of the pipeline is greatly improved, and due to the fact that the pipeline is filled with water, electric heating is not prone to generating the overheating phenomenon. Theelectric heating steel pipe composite thermal insulation plastic pipe device represents the development direction of thermal insulation pipes.

Description

technical field [0001] The invention relates to an electric heating steel pipe composite thermal insulation plastic pipe device, which belongs to the field of liquid conveying pipes. Background technique [0002] At present, the known pipes used for liquid delivery pipes are mostly aluminum-plastic composite pipes, plastic pipes, or steel pipes. In winter, when the insulation of the pipeline is poor, the pipeline is often blocked by freezing. Moreover, due to the freezing and expansion of the pipeline, the disadvantages of freezing and cracking of the upper and lower water pipelines often occur, resulting in the failure of normal use. For some organic chemical products, the transportation is even more difficult when the temperature is low. Because the pipeline has insulation, even when the temperature rises, the ice in the pipeline is not easy to melt. In order to solve the above problems, it is usually used to prevent the liquid delivery pipe from freezing and cracking by...

Problems solved by technology

Since the heating cable is installed on the outer wall of the pipeline, it cannot be in good contact with the pipeline, and the thermal resistance is increased, so that the utilization rate of heat generated by the heating cable is low, so it consumes a lot of power, has poor ice melting performance, and has poor application effect. Poor, and often fire, not safe enough
