After the life of the pipeline coating is over in terms of economics and the costs of the cathodic protection system, a lot of cathodic current is needed to protect the pipelines, so the best method is to replace the pipeline coating. One of the suitable coatings for replacing the coating of pipelines, valves and fittings is to use 100% solid polyurethane. The obvious properties of this type of coating, apart from the ease and speed of implementation in the field sites and workshops of this company, are the unique mechanical and chemical properties that are the superiority of this coating over the old coatings, especially for the purpose of replacing the coating, which is described below. They are mentioned: - High resistance to soil stress wear Fast curing capability even at low temperature - Strong adhesion and continuity (due to implementation in one step) - High resistance in acidic and alkaline PH - Zero VOC (no pollution due to evaporation of organic compounds) - Complete uniformity of the coating along the entire length of the pipeline (in the case of replacing the coating) It should be noted that this product can also be used to cover concrete surfaces, flooring, warehouses, stadiums, etc.
