The most critical working process of the heat exchanger

The first step: cleaning. In the cleaning tank in the circulating water according to the proportion of added configured cleaning agent for boiler cleaning, according to the scale to determine how much cleaning cycle time and adding the number after the confirmation of all the dirt washed down into the next step of cleaning procedures.
The second step: Shimizu Shirai. After the cleaning equipment and the boiler connection is good, must use clean water to clean 10 minutes, check the system status, whether there is leakage, at the same time, rust cleaning out.
The third step: stripping anti-corrosion cleaning. According to the proportion of circulating water in the cleaning bath adding surface peeling agent and release agent, cleaning cycle for 20 minutes, so that the separation of components of dirt and cleaning, and anti-corrosion treatment on the surface of the object without fouling, prevent cleaning when cleaning agent on cleaning parts due to corrosion.
Fourth step: passivation coating treatment. Passivation coating agent was added to the boiler cleaning system for passivation coating treatment, prevention and control of the corrosion of the pipeline and components, and the formation of new rust scale.
