Abstract

The invention relates to the technical field of plastic-coated steel pipe manufacturing, and discloses plastic-coated steel pipe manufacturing equipment and a manufacturing process. The plastic-coatedsteel pipe manufacturing equipment comprises a feeding device, tracks and a discharging device, wherein the tracks comprise the y-direction track and the x-direction track which are mutually connected in a perpendicular mode, an inner spraying device, a steel pipe fixing assembly and a steel pipe preheating device are sequentially installed on the y-direction track, the steel pipe fixing assemblyis matched with the feeding device, the steel pipe fixing assembly comprises a first fixing device and a second fixing device which are symmetrically arranged, the steel pipe fixing assembly furthercomprises a supporting seat fixed to the y-direction track, the supporting seat is located between the first fixing device and the second fixing device, and the manufacturing equipment further comprises an outer spraying device and a curing box which are sequentially arranged along the x-direction track. In conclusion, feeding, fixing, spraying, curing and discharging of a steel pipe are achievedin a full-automatic mode, meanwhile, inner spraying and outer spraying of the steel pipe are completed at a time in the spraying process, and therefore the production efficiency of the plastic-coatedsteel pipe is greatly improved.

Description

technical field [0001] The invention relates to the technical field of manufacturing plastic-coated steel pipes, in particular to manufacturing equipment and a manufacturing process for plastic-coated steel pipes. Background technique [0002] Plastic-coated steel pipes, also known as plastic-coated pipes, steel-plastic composite pipes, and plastic-coated composite steel pipes, use steel pipes as the substrate, and weld a layer of plastic anti-corrosion layer or Steel-plastic composite steel pipe with plastic anti-corrosion layer welded on the inner and outer surfaces. [0003] In the prior art, the manufacturing steps of the plastic-coated steel pipe mainly include: preparing a rough steel pipe, preheating the rough steel pipe, performing internal and external spraying of the rough steel pipe, curing, respraying, and re-curing; [0004] Among them, when performing the internal and external spraying operations of rough steel pipes, most of them are done manually, so there a...
