A516 Gr 415 plates API Std 650 flexible liquid storage tanks

The main content of the inspection of the safety management of metal atmospheric API Std 650 flexible liquid storage tanks is whether the filed data of the storage tanks are complete; whether the operators have received safety management training; whether the problems detected in the past have been resolved. The main inspection content of the tank body of the metal atmospheric pressure storage tank is whether the tank top, tank wall, and bottom plate of the storage tank are deformed, dented, seepage and perforation, etc.; whether the API Std 650 flexible liquid storage tanks accessories are complete and whether there are any abnormalities; No sinking, tilting, etc.In this project, a cylindrical tank 62 ft 6 in. in diameter is designed for an internal pressure of 4 lbf/in.2 gauge in the vapor space. The plate material is ASTM A131 steel with appropriate grades for different plate thicknesses in accordance with Table 4-1 for a design metal temperature less than 65°F but not less than 25°F. No corrosion allowance is required for any portion of the tank. The top course of the butt-welded cylindrical sidewall is 1/4 in. thick. The roof is a single lap-welded spherical dome with an internal radius of 50 ft and a thickness of 1/4 in. The maximum design liquid level is 6 in. below the plane of the juncture of the tank API Std 650 flexible liquid storage tanks roof and sidewall.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 flexible liquid 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 flexible liquid storage tanks inner floating roof means that the cost of the inner floating roof can be recovered within half a year.Enterprise mission: to create value added steel products API Std 650 flexible liquid storage tanks and provide first-class serviceWe are committed to quality.
