A516 Gr 380 plates API Std 650 floating-roof tanks

Volatilization is the characteristic of oil. Under normal temperature and pressure, as long as the oil is in contact with air, the surface will volatilize. Through scientific analysis and summary, the causes of oil volatilization loss in API Std 650 floating-roof tanks are: natural ventilation loss, static storage loss, dynamic liquid level loss. In the use of API Std 650 floating-roof tanks, static storage loss and dynamic liquid level loss are common losses.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 floating-roof 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.The API 650 specification provides guidelines for the API Std 650 floating-roof tanks design, manufacturing, materials, installation and inspection of welded vertical and cylindrical tanks. Such containers must be on the ground and have a closed or open top.Corporate mission: to provide high quality steel products API Std 650 floating-roof tanks and services to global customers.Strategic goal: to be the leading steel materials supplier in the world.Enterprise core values: people-oriented, customer first, quality oriented, comprehensive and open, continuous innovation.Customer first is to always put the satisfaction of customer needs first.
