API standard 650 low-alloy steel tanks roof flotation test
API 650 storage tank, double-layer oil tank environmental protection advantages: ordinary single-layer steel API standard 650 low-alloy steel tanks oil tank is corroded by underground water and gas and electrolytic corrosion because it is buried underground all year round. The API 650 tank has a double-layer structure with a gap of 0.1 mm. The API standard 650 low-alloy steel tanks outer layer of FRP ensures that the leakage will not directly leak into the soil and water source.
Oil storage tank is an important equipment commonly used in petroleum and petrochemical industry. New API standard 650 low-alloy steel tanks, metal storage tank must be tested before it can be put into use or put into storage. The common inspection methods of API standard 650 low-alloy steel tanks include radiographic testing, ultrasonic testing, magnetic particle testing and dye penetrant testing. The parts and operation requirements of these testing methods are different, so they should be selected according to the required characteristics.
Proof Tests for Establishing Allowable Working PressuresBecause pressures in liquid storage tanks built according to these rules vary quite markedly from the tops to the bottoms of the tanks, proof testing of these tanks presents problems not usually encountered in the construction of unfired pressure vessels–especially where the API standard 650 low-alloy steel tanks parts under investigation are located near the bottoms of the tanks. The principal difficulty is devising a test or series of tests that will reliably establish the working pressure that can be permitted on the part of the unproven design without, at the same time, imposing hazardous conditions on other parts located at higher levels in the tank.
