Stainless steel welded pressure water tank

Stainless steel welded pressure tank is widely used in the regulation of building water supply, storage tanks, hot water for hot water system insulation, condensate tank. The utility model solves the defects that the traditional water tank has the problems of making and installing, difficult installation, poor antiseptic effect, short service life, easy leakage of the assembled water supply tank and easy aging of the rubber strip. With the manufacture of a high degree of standardization, making flexible, do not have lifting equipment, do not pollute the water quality and so on. Common failures and treatment methods of stainless steel welded tanks As industrial and domestic water generally contain chloride ions (Cl-), metal-made hot water containers are always perennial in the corrosion environment containing Cl-water below 80 ℃, prone to local Corrosion and its service life is limited. Compared with uniform corrosion (chemical corrosion), local corrosion (electrochemical corrosion) is much faster, the risk is much greater, often leading to leakage failure. Among Cl-containing aqueous media, the weakest part of stainless steel tanks that is most susceptible to corrosion is the weld zone, which is subject to high temperature heating, deterioration of texture and properties, and corrosion resistance. Stainless steel tank material is generally Cr stainless steel, nickel-free material due to lead to the welding parts of the tank in the course of the corrosion leakage problems are more common. The traditional method of repair welding is more difficult, the thermal stress may cause greater damage or damage; brush epoxy corrosion-resistant materials due to surface adhesion and expansion coefficient and other properties, or may appear cracking, peeling, etc. Phenomenon once again aggravate the corrosion. For different equipment, different operating conditions, different forms of corrosion and leakage, the use of the corresponding technology products, can be quickly, simply and effectively protect the equipment, especially due to the polymer composite materials have chemical corrosion resistance, bonding properties such as comprehensive performance , To avoid the traditional repair repairs and the traditional anti-corrosion materials, the adverse effects of protection, the repair of equipment or even more than the life of new equipment, to fundamentally solve the causes of corrosion and leakage, to help enterprises improve equipment management, reduce maintenance and repair Cost, improve the competitiveness of enterprises. Steps: Surface treatment: first with a grinder to clean the surface of the scale leaking parts, and then use right-angle welding position with the electric mill to clean the surface carefully cleaned with a sandpaper exposed metal surface, and then thoroughly clean the surface with anhydrous ethanol. Reconcilable material: The 1321 material in accordance with the ratio of 3: 1 reconcile and stir until there is no color. Applying material: The 1321 material will be adjusted to focus on the protection of welding parts of the weld, and then use a large area of 1321 anti-corrosion protection of materials. Curing time: 24 hours / 24 ℃ (material temperature). As the material temperature increases by 11 ℃, the curing time will be shortened by half, but the temperature should not exceed the material withstand temperature.
