Construction process of winding epoxy coal tar pitch fiberglass reinforced plastic on the outer wall of buried pipelines
Thread Content
For minor renovations of buried pipelines, epoxy coal tar fiberglass-reinforced plastic technology can be used for corrosion protection. For anti-corrosion construction, using manual and mechanical winding methods, along with a feeding process in which glass cloth is soaked in coating, can yield excellent quality. The images below show the construction process.
For the epoxy coal tar pitch fiberglass-reinforced plastic anti-corrosion treatment of buried pipelines, it is first necessary to clean the surface of the pipes thoroughly, removing rust and impurities. Then, the epoxy coal tar pitch coating is evenly applied to the outer wall of the pipe. Next, glass cloth soaked in epoxy coal tar paint is wrapped around the outer wall of the pipe manually or mechanically, to ensure even coverage of the glass cloth without any air bubbles. Finally, the coating is allowed to dry and cure, forming a robust anti-corrosion layer to protect the pipeline. .
