Description

Technical Field

[0001] The present application relates to the field of pipe bending machines, and in particular to a heating pipe continuous bending device. Background Art

[0002] Heating tubes are electrical components that convert electrical energy into heat. Due to their simple manufacturing process, low price, ease of use, installation, and pollution-free operation, they are widely used in various heating applications.
