Anticorrosion of anticorrosion spiral pipe for epoxy coal tar

 Epoxy coal tar pitch anticorrosion coating is composed of two main components of epoxy and coal bitumen. It is a double component coating of a (epoxy) B (curing agent). It has excellent adhesion, toughness, moisture resistance, water resistance and chemical resistance. It has the properties of preventing various ions through the film, and has the same expansion and contraction as the coated object. Characteristics. The film never shedding and cracking. The thickness is 0.5 to 1.0mm. Epoxy coal tar is a kind of anticorrosive form with high cost performance. The engineering test shows that epoxy coal tar is applied to cathodic protection. Oil and gas pipelines have not been corroded for twenty years.
