ISO 630 grade E275 quality C plates API 650 fixed roof tanks

The structure of the API 650 Fixed roof tanks foundation mainly includes the insulating anticorrosion layer on the top surface of the foundation, the tank wall support, the edge retaining structure, the sand cushion, the oil and water barrier, the detection signal tube and other structures. The construction materials and requirements of each basic structure of the storage tank are different. After the structure of the API 650 fixed roof tanks foundation is built in accordance with the construction requirements, the settlement of the storage tank foundation needs to be observed, and the uneven settlement value of the storage tank foundation should be within the allowable safety range.API 620 Crude Oil Tank Pneumatic Pressure
An air pressure equal to 1.25 times the pressure for which the vapor space is designed shall be applied to the enclosed space above the water level. In the case of a double-wall tank with an open-top inner tank, where the air pressure acts against the outer tank and the inner tank is thus not stressed by the air pressure, the inner API 650 fixed roof tanks may be emptied of water before the pneumatic pressure test begins. The test pressure shall be held for 1 hour.This API 650 tank standard is designed to provide industry with tanks of adequate safety and reasonable economy for use in the API 650 fixed roof tanks storage of petroleum, petroleum products. and other liquid products.Our company was founded in 2009, and has been committed to steel business since its establishment.
