A662 Gr C plates API 650 aboveground oil storage tanks

refrigerated tanks secondary components are those whose failure would not result in leakage of the liquid being stored. Secondary components also include those API 650 aboveground oil storage tanks components that are not in contact with the refrigerated liquid but are subject to the refrigerated temperature vapors and have a combined tensile and primary bending stress under design conditions that does not exceed 6000 lbf/in.2. Secondary components that could be designed within this reduced stress are roof plates, including roof manways and nozzles with their reinforcement, roof-supporting structural members, and shell stiffeners.The characteristics of the API 650 aboveground oil storage tanks internal floating roof structure of API 650 petroleum storage tanks: the inner floating roof or inner floating plate refers to the floating roof that floats on the liquid surface of the oil tank with the oil and liquid up and down. The API 650 aboveground oil storage tanks inner floating roof is used to cover the liquid. The surface is currently recognized as the most ideal and most economical and practical way to reduce oil evaporation loss.We exported 2150 Tons SG295 steel coils to Sudan. The Sudan customer is LPG cylinder manufacturer. Before our cooperation, he usually purchased SG295 steel coils from UAE and Turkey. And he got to know our company through our regular customers in Uganda, UAE, and his friends in China. Then he gave us the order. We invited the customer to visit us before contract, but he insisted to visit us when the API 650 aboveground oil storage tanks goods are finished production. After inspecting the size, package in workshop and witness the lab test for the SG295 steel coils, the customer was very satisfied to our quality control and professional arrangement.Inspection of API 650 aboveground oil storage tanks bottom: magnetic flux leakage scanning technology is used to detect the corrosion condition of API 650 aboveground oil storage tanks bottom plate (such as corrosion depth and area, crack length, etc.). When there is a defect in the bottom plate of the API 650 aboveground oil storage tanks, the magnetic field distribution will change and the sensor can detect it. The bottom of the oil tank should be free of foreign matters and dry during testing. Weld inspection of API 650 aboveground oil storage tanks bottom plate: when vacuum leak test method is used to detect the tightness of oil tank bottom plate, soap water shall be applied to the weld and vacuum box shall be covered for observation.The company conducts periodic and targeted training and guidance for after-sales service personnel. As the saying goes, "no one is perfect, no gold is red", to help after-sales service personnel improve service skills and correct service attitude. Carry out relevant technical training for after-sales service personnel, so that after-sales service practitioners have professional product knowledge.
