3LPE Fusion Bonded Epoxy Coated PE Winding Elbow Steel Pipe Coating Equipment
Hot bending pipe shot blasting and rust removal operation line can clean hot bending pipe (including some section steel and structural parts with reasonable size) at one time. It can not only remove the rust and scale on the surface of the workpiece, but also remove the welding slag on the structural parts. It can also eliminate the welding stress of the workpiece, improve the fatigue strength of the workpiece, obtain a bright surface with a certain roughness, increase the adhesion of the epoxy powder or anti-corrosion coating of the hot bending pipe (or section steel components), and finally achieve the purpose of improving the surface and internal quality 
This setup ensures optimal conditions for the winding anticorrosion process.
