Epoxy coal tar pitch coating for oil and gas pipelines

Thread Content

Given the current stage of development in our country, there are two main components of this coating technology: coal tar and epoxy resin, both of which possess strong corrosion-resistant properties. Therefore, in practical use, this coating technology, thanks to its excellent waterproof properties, resistance to microbial and soil corrosion, as well as strong adhesion, can greatly prevent oil and gas transmission pipelines from being corroded. However, this type of coating requires a long time to cure during application, and during this curing process, the relevant staff must ensure that the pipes remain clean and free from any contamination, which poses significant challenges in today’s context. This also determines that this coating technology is suitable for repairing corrosion-resistant coatings as well as on irregular pipes.
