API 650 aluminum storage tanks repair of defective welds

,API 650 aluminum storage tanks. Visual InspectionUpon completion of all the foregoing tests, the pressure in the tank shall be released and a thorough visual inspection shall be made of both the inside and outside of the tank, giving particular attention to all internal ties, braces, trusses, and their attachments to the walls of the tank. Anchors shall be checked for snug tightness and adjusted if required. Anchor threads shall be fouled by peening or tack welding to prevent loosening. In lieu of thread fouling, double nuts may be used.Rate of Water Filling and Water TemperatureThe rate at which water is introduced into a tank for a hydrostatic test shall not exceed 3 ft of depth per hour. The foundation, venting equipment, or other conditions may limit the water filling to a lower rate. Pressure shall not be applied above the surface of the water before the tank and its contents are at about the same temperature.API 650 petroleum storage tanks use lightning protection, anti-static, and fire protection measures. The internal corrosion protection should be determined according to the API 650 aluminum storage tanks storage medium, and the outer wall corrosion protection should be determined according to the soil quality of the buried tank.BBN steel had provided Grind plates for more than 15 years for widely applied in equipment, Engineer machinery etc. In 2018, one of our India customer visit our API 650 aluminum storage tanks office and work shop to discuss Q235B Grind plate technical request, they have strict surface and thickness tolerance, and they also request UT and MT for testing. As a result, they purchase API 650 aluminum storage tanks 179 tons as trial order for first cooperation. And have good comment on our quality. Till now, we keep exporting around 100 tons per month as regularly.Usually, the wind load in the API 650 aluminum storage tanks construction area should be considered before the tank design and construction. The wind load in the API 650 aluminum storage tanks construction area has an impact on the stability and economy of the API 650 aluminum storage tanks. In the area with large wind load, it is safe to design the tank as "squat". When calculating the wind force, the influence of the thickness of the insulation layer of the API 650 aluminum storage tanks, the shape of the ladder, the platform, the pipeline and the top cover must be considered.We are willing to cooperate sincerely with you with high-quality API 650 aluminum storage tanks products and sincere service to expand the market and create brilliant!
