Ylindrical API Std 650 closed top welded storage tanks
The advantages of API 650 floating roof tanks have obvious environmental and economic benefits: in a specific climate environment, according to historical data, the economic value of the API Std 650 closed top welded storage tanks floating roof tanks in API 650 due to the reduction of oil and gas volatilization within 3-6 months is equivalent The installation and purchase cost of the API Std 650 closed top welded storage tanks inner floating roof means that the cost of the inner floating roof can be recovered within half a year.
Pressure Setting of Safety DevicesExcept as provided in API 620 tank 9.5 for certain liquid relief valves, the pressure setting of a pressure-relieving device shall in no case exceed the maximum pressure that can exist at the level where the device is located when the pressure at the top of the tank equals the nominal pressure rating for the tank (see API 620 tank 5.3.1) and the liquid contained in the tank API Std 650 closed top welded storage tanks is at the maximum design level.Vacuum-relieving devices shall be set to open at such a pressure or partial vacuum that the partial vacuum in the tank cannot exceed that for which the tank is designed when the inflow of air (or other gas or vapor) through the device is at its maximum specified rate.
Welding inspection of bottom plate of API Std 650 closed top welded storage tanks, vertical oil tank: During the fabrication and installation of API Std 650 closed top welded storage tanks, the bottom edge plate is welded first. According to the requirements of the technical standard, penetrant inspection is required for the weld of edge plate at the bottom of API Std 650 closed top welded storage tanks, that is, penetrant testing is required for each weld bead priming, filling and capping. In the process of testing, if any defect is found, it shall be repaired immediately. After the repair, the surface coloring penetrant test shall be conducted again until the test result is qualified.
