7, the insulation layer and the outer tank with a solid, smooth appearance. Better insulation using polyurethane foam plastic insulation material or performance; outer decorative shell with stainless steel or other suitable material tank factory, uneven surface may not have scratch marks or rust, to the requirements of Table 2. 8, tolerances for dimensions shall meet the requirements of Table 3. 9, the tank filled with water, not a seepage, leaking tanks, there should be no significant deformation phenomenon, according to the welded steel pressure vessel filled with water experiments related terms. (GB50242-2002 Building Water and Heating Engineering Construction Quality Acceptance) stainless steel tank material is generally Cr stainless steel fire water tank, because the material does not contain nickel lead tank welded parts appear in the course of corrosion leakage problems are more common. The traditional method of welding larger difficulty, heat stress may cause more damage; brush epoxy corrosion-resistant materials due to adhesion and expansion coefficient of the surface of the performance impact, or there will be cracking, peeling, etc. aggravate erosion phenomenon again. For different devices, different operating states, different forms of corrosion leaks modular stainless steel water tank, using appropriate technology, enables fast, simple, and effective protection devices, especially due to the chemical resistance of polymer composites has the energy, bonding performance overall performance, avoid the adverse effects of traditional welding repair and protection of traditional corrosion-resistant materials brought to make the life of the repaired equipment even more than new equipment, corrosion, leakage reason fundamentally resolved to help enterprises improve equipment management level reduce repair and maintenance costs and improve the competitiveness of enterprises. FRP fire water tank, air conditioning Echo (certified), water is provided by the Texas Air Conditioning Equipment Co. Echo. Echo Air Conditioning Equipment Co., Texas (www.aikekt.cn) is Dezhou, central air conditioning leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
