The seismic effects on the tank wall of API 650 oil storage tank include the inertia moment generated by the weight of the api 620 tank design pressure tank and the hydrodynamic pressure of the reservoir, which can be divided into short period pulse pressure and long period fluid slopping convective pressure.

Product concept: take the technology leading as the pillar of the enterprise, achieve the development goal of the enterprise with the reliable products, the reliable technology and the trustworthy services, and devote to the creative reform activities leading in the technical development and career of the industry to create new value through continuous change.

Ultrasonic testing can find the internal defects of api 620 tank design pressure welding joint, this detection method is very accurate for the internal layer defects of oil tank, but ultrasonic detection is not suitable for the detection of thin-walled storage tank materials. Dye penetrant testing is only suitable for detecting the defects of the surface opening of api 620 tank design pressure and so on metal oil tanks. The feature of this method is convenient and fast.
