1. Pay attention to corrosion resistance and iron ion pollution
The scaffolding of pressure vessels should be considered from the perspective of corrosion resistance and prevention of iron ion contamination. Applying acid-resistant paint to buckles and springboards not only enhances corrosion resistance, but also prevents iron ion contamination. In order to prevent the scaffolding of the pressure vessel from damaging the bottom of the gas storage tank, you can choose to place a layer of rubber or straw curtains or wooden boards at the bottom of the pressure vessel to isolate it. Regarding the surface cleaning of pressure vessels, you can first remove the spatter and welding slag on the surface of the weld and storage tank, and then apply solder paste to the high-temperature oxidation part of the weld and the heat-affected zone of the weld to remove oxide scale and remove steel Various greases on the surface.

2. Pay attention to seal the can in time to protect the finished product
When removing the scaffolding after pickling and passivating the pressure vessel, care should be taken not to damage the passivation film through sticks, buckles and springboards stuck to the tank wall. Wear soft-soled rubber shoes when pickling and passivating the bottom of the gas tank. To destroy the passivation film, place a layer of rubber skin on the bottom of the tank if necessary. After passing the inspection, the water stains should be dried with compressed air in time, and then the cans should be sealed to protect the finished product. It should be noted that the temperature of the cleaning fluid and pure water should not exceed the standard to avoid overheating and affecting the function of the water tank.
