Epoxy resin composite steel pipe is widely used in fire water supply. In the building fire protection system, epoxy steel pipe plays an important role and gradually replaces the galvanized steel pipe. Let us introduce the production process of the inner and outer coated epoxy steel pipe, the performance of the powder (epoxy resin), and the inside and outside. Product performance of epoxy coated steel pipes.
When spraying, the epoxy resin powder is not completely fused to the inner and outer walls of the substrate. After 30 minutes of preheating and curing, the curing agent in the epoxy resin is completely cured, so that the coating of the inner and outer walls is more adhesive and thermosetting. The powder characteristics are fully apparent.
