Test plates shall be made from plates produced only from the heats that are used to produce the shell plates for the large welded steel tank.API 650 internal floating roof oil tank is a volatile liquid storage tank with a combination of a dome tank and an internal floating roof structure, which is a floating roof assembled under the dome of the API Std 650 flexible liquid storage tanks storage tank. The combination of the vault roof outside the API 650 storage tank and the floating roof inside the tank has been widely used in gasoline, aviation kerosene and more volatile chemical liquids.In order to better develop the international steel market and make the steel products trade more prosperous at home and abroad, the company has a number of professional talents who love their posts and are proficient in their business. The company has always been adhering to the "service first, reputation first, customer first, make friends" business purpose, is willing to work together with domestic and foreign customers!The lip seal of floating roof storage tank, API Std 650 flexible liquid storage tanks relies on the sliding contact between elastic lip and tank wall. This kind of seal has strong applicability, but the requirements of manufacturing technology and material selection are high, and the determination of elastic seal also exists. The secondary seal of floating roof storage tank, API Std 650 flexible liquid storage tanks is to add a seal on the basis of primary seal. It is proved by experiments that the secondary seal can reduce the liquid consumption by more than 50%, and has a more significant effect in safety.
