Abstract
In this article, it introduced the characteristics of internal resistance-reducing coating and the requirements to coating performance in the corresponding standards. Combing with steel pipe internal coating process, it analyzed the influence of viscosity change on steel pipe internal coating, and regarded that the influence of viscosity change is one of the important factors for steel pipe coating. When the coating temperature is low, based on the change of coating temperature, it should adopt proper preheating temperature preservation measures, to improve the coating thickness difference , to reduce quality defects , and enhance the utilization efficiency of coating material. The results indicated that adopting proper preheating temperature preservation measure, it can improve the quality of coating and reduce the material consumption of per unit area of the internal coating, thus to low the cost of internal coating.关键词
