5456 aluminum tube API Std 650 SUG I tanks

API Std 650 SUG I tanks Liquid Relief ValvesA tank, which is likely to operate completely filled with liquid, shall be equipped with one or more liquid relief valves at the top of the roof, unless otherwise protected against overpressure. When such valves are, in effect, supplementary relief devices, they may be set at a pressure not greater than 1.25 times the design pressure. Because the relief valve at the pump, which provides the inflow of liquid to the tank, is set at a pressure greater than 1.25 times the design pressure of any tank that may be built under these rules, provision should be made for preventing overfilling of the tank by a self-closing float valve, by some practicable pilot-valve control, or by any other proven device.

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 SUG I 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 SUG I tanks inner floating roof means that the cost of the inner floating roof can be recovered within half a year.

After the API Std 650 SUG I tanks is manufactured, air tightness test and water filling test are carried out according to the design requirements, and the pipeline must be subjected to pressure test to fully meet the acceptance technical specifications. Improve the quality assurance system, adhere to the principle of who constructed is responsible for the quality of the project, conduct regular quality inspections, and immediately rectify any problems. Fill in the API Std 650 SUG I tanks installation technical records in time to ensure the synchronization, integrity and reliability of the technical data.
