Welded API standard 650 welded steel storage tanks

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 standard 650 welded steel 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.

The finned tube heating device for high temperature heat transfer oil for large API standard 650 welded steel storage tanks has the advantages of convenient inspection and maintenance. The high-efficiency fin heating coil assembly is composed of spirally arranged finned coils. The fins are mainly arranged in the straight pipe section, and the whole assembly is supported by several angle steel supports. The high-efficiency fin heating coil component can enter and exit from the manhole of the API standard 650 welded steel storage tanks, which is convenient for maintenance and repair.

Preheat Treatment
Many laboratory tests have shown preheat treatment of carbon steel to 300°F-400°F to be the equivalent of the post-heat treatment at no less than 1100°F insofar as the physical properties of the weldment are concerned.40,41 Some tests have indicated a slight advantage of the post-heat treatment. Most of the tests have been made on plates 3/4 in. - 1 in. thick; results must be viewed with caution if preheating is applied appreciably beyond this thickness range. However, for all practical purposes, improvement resulting from preheating is sufficiently well established so that preheat should be considered for field fabrication of API 620 crude oil tank plates over 3/4-in. thick whenever toughness of the tank API standard 650 welded steel storage tanks is highly desired and the thermal post-heat treatment is impractical.
