Exploring a method to effectively avoid drop-out of internal coating in natural gas pipelines

Internal coating technology of natural gas pipelines has brought us huge economic benefits, but the peeling phenomenon is becoming the bottleneck of utilization. How to enhance the adhesive force and effectively avoid drop-out of coating has developed into an urgent problem needing to be resolved. In this article, the characteristics and properties of coating are investigated and explored. In addition, the timely application of flexible rolling during the curing process is proposed in order to prolong the operation cycle of internal coating significantly.
