Solution Stainless steel tank failure

As the industrial and domestic water generally contains chloride ions (Cl-), metal hot water containers are always perennial below 80 ℃ with Cl-water corrosion environment, prone to local corrosion and its life is limited. Compared with uniform corrosion (chemical corrosion), local corrosion (electrochemical corrosion) is much faster and more dangerous, often leading to leakage failure. In the water medium containing Cl-, the weakest part of the stainless steel tank is corrosion, and the corrosion resistance is also reduced due to the high temperature heating and the deterioration of the structure and properties.
Stainless steel water tank material is generally Cr stainless steel, because the material does not contain nickel water tank welding parts in the course of the use of corrosion leakage problems are more common. The traditional method of repair welding is more difficult, the impact of thermal stress or cause greater damage; brush epoxy corrosion-resistant materials due to the surface of the cohesive force and expansion coefficient and other properties, there may be cracking, stripping, etc. The phenomenon once again increased corrosion. In 2013, more effective methods to use polymer composite materials, which is more mature US Ka Wah series of applications. For different equipment, different operating conditions, different forms of corrosion leakage, the use of appropriate technology products, can be fast, simple and effective protection equipment, especially due to polymer composite materials with anti-chemical corrosion, bonding performance and other comprehensive performance , To avoid the traditional repair welding and traditional anti-corrosion material protection brought about by the adverse effects of the equipment after the repair even more than the new equipment, a fundamental solution to the reasons for corrosion and leakage to help enterprises improve equipment management level, reduce maintenance and maintenance Cost, improve the competitiveness of enterprises.
Steps:
Surface treatment: first use the angle grinder to clean the surface of the water leakage parts of the scale, and then use the right angle weld position with electric grinding to clean the surface, carefully clean the surface with sandpaper exposed metal primary colors, and then completely clean the surface with anhydrous ethanol.
Harmonic material: 1321 material in accordance with the ratio of 3: 1 to reconcile and stir until there is no color.
Apply the material: the 1321 material will be transferred to focus on the brush to protect the weld parts, and then use a large area 1321 material corrosion protection.
Curing time: 24 hours / 24 ℃ (material temperature). Material temperature for each promotion 11 ℃, curing time shortened by half, but the lifting temperature shall not exceed the material to withstand the temperature.
