Rail car interior water tank

Water tank according to the material can be divided into: stainless steel water tank, enamel steel water tank, FRP water tank, PE water tank and so on. Among them, fiberglass water tank is made of high-quality resin as raw materials, coupled with excellent molding production process, with light weight, no rust, no leakage, good water quality, wide range of use, long service life, good insulation performance, beautiful appearance, easy installation, easy cleaning and maintenance, strong adaptability, etc. Widely used in hotels, schools, hospitals, industrial and mining enterprises, institutions, residential buildings, office buildings, is the ideal product for public water, fire water and industrial water storage facilities.

Stainless steel welded atmospheric water tank
Stainless steel welded atmospheric water tank is widely used in building water supply regulation, storage water tank, hot water thermal insulation storage of heating water system, condensation water tank. It solves the traditional water tank production, installation difficulties, poor anti-corrosion effect, short service life, and prefabricated water tank easy leakage, rubber strip easy aging and other defects. It has the advantages of high manufacturing standardization, flexible production, no lifting equipment, no pollution of water quality and so on. Due to the widespread inclusion of chloride ions (Cl-) in industrial and domestic water, metal hot water containers are always in a corrosive environment containing Cl- water below 80 ° C all year round, prone to local corrosion and its service life is limited. Compared with uniform corrosion (chemical corrosion), local corrosion (electrochemical corrosion) is much faster and more dangerous, often resulting in leakage failure. In the water medium containing Cl-, the weak link of the stainless steel water tank that is most prone to corrosion is the welding area, because the area has been subjected to high temperature heating, the organization and performance are degraded, and the corrosion resistance is also reduced. The material of stainless steel water tank is generally Cr stainless steel, because the material does not contain nickel, the corrosion and leakage problem of the welding part of the water tank in the process of use is more common. The traditional repair welding method is more difficult and may cause more damage under the influence of thermal stress. Brush epoxy corrosion resistant materials due to the surface adhesion and expansion coefficient and other properties, or there will be cracking, stripping and other phenomena aggravate the corrosion again. For different equipment, different operating states, different forms of corrosion leakage, the use of corresponding technical products, can quickly, simply and effectively protect the equipment, especially due to the polymer composite material has chemical corrosion resistance, bonding performance and other comprehensive properties, to avoid the adverse effects of traditional repair welding repair and traditional corrosion resistant material protection. Make the repaired equipment life even more than the new equipment, fundamentally solve the cause of corrosion leakage, help enterprises to improve the level of equipment management, reduce maintenance costs, improve the competitiveness of enterprises. Operation steps: Surface treatment: First use the Angle grinder to clean the scale on the surface of the leaking part, then use the electric mill to clean the surface of the right Angle weld, carefully clean the surface with sandpaper to expose the metal primary color, and then use anhydrous ethanol to thoroughly clean the surface. Blend ingredients: Blend 1321 ingredients in 3:1 ratio and stir until there is no color difference. Coating material: Brush the adjusted 1321 material to protect the weld parts, and then use 1321 material for large area anti-corrosion protection. Curing time: 24 hours /24℃ (material temperature). For every 11 ° C increase in material temperature, the curing time is reduced by half, but the increase temperature must not exceed the withstand temperature of the material
