Technical Problems to be Solved in Outside Surface Galvanized and Inside Surface Plastic Coated Steel Pipe for Main Gas Pipe Line
The article introduces the processing technology of outside surface galvanized and inside surface plastic-coated steel for the main gas pipe line. It shows a better processing technology through the contrast, the quality of the membrane of the hot-galvanized steel pipe of inside surface coated LLDPE under the condition of special phosphorization process is equal to that as the result of rotoblasting technology. At the same time, anti-corrosion effect is better than before because of multi-layered and differently plated coatings. A Y-interface technology of independent intellectual property rights is used in interface.
