Internal coated pipe coating process selection
Anti-corrosion coating is a corrosion in the harsh conditions of excellent corrosion resistance, long life special coating. Good chemical stability in corrosive media, strong adhesion, flexibility, anti-foaming loss of pressure, the mechanical properties (abrasion resistance, impact resistance) and good, so that the metal corrosion mitigation and prolong life. An anti-corrosion coatings for it can only play its role in certain circumstances, it is impossible to meet the different requirements of various environments, which according to the actual situation, to take coating process "Multilayer alien" structure. General engineering construction, mainly in the form of the structure of the intermediate layer + primer + topcoat in order to achieve more satisfactory preservative effect. Because primer attached directly to the substrate metal, so it should have good adhesion; an intermediate layer as a primer and topcoat transition, which in addition to the primer, paint has good adhesion performance, but also To have a strong shielding effect; the role of the outer coating of paint as the most important, different environments have different requirements, generally requires finish on the surrounding environment and climate have good corrosion resistance.

The main process steps in the coating
Popular at home and abroad in the coating process: preheat the pipe surface treatment → end of the tape dust protection → airless → accelerate the curing → inspection → stack (stored to be transported). The key to its quality control: the choice of paint, surface treatment, airless spray, dry film thickness and cure the coating.
