[0002] Plastic coated steel pipe, also known as plastic coated pipe, steel-plastic composite pipe, plastic coated composite steel pipe, is a steel-plastic composite steel pipe with a steel pipe as the base. A layer of plastic anti-corrosion layer is welded on the inner surface of the steel pipe (bottom pipe) or a plastic anti-corrosion layer is welded on the inner and outer surfaces through spraying, rolling, dipping and suction processes. When the steel pipe is processed, its inner wall needs to be plastic coated. After the plastic coating of the inner wall of the steel pipe is completed, it needs to be dried. The "plastic coated steel pipe inner wall plastic coating baking device" disclosed in the application number "CN215997392U" has solved the technical disadvantages of the baking method of heating the outer wall resulting in poor effect, but in actual use, devices with similar structures still have many defects.
