API 650 partially anchored liquid-storage tanks seismic design

The API 650 partially anchored liquid-storage tanks external floating roof tank of API 650 tank has many advantages, and its application range is more and more wide. It is a kind of storage tank with a bright future. The well-designed internal floating roof tank of API 650 tank is the best and least investment method to control evaporation loss of API 650 partially anchored liquid-storage tanks Fixed roof tank.

API 650 partially anchored liquid-storage tanks, Floating roof tank is composed of vertical cylindrical tank wall and floating roof, which is floating on the surface of liquid storage. The volume of floating roof storage tank is generally large, and its bottom plate is arched edge plate. The difference between floating roof tank and other types of storage tank is that there is a floating top cover floating on the surface of liquid storage, and the top cover floats up and down with the rise and fall of liquid storage.

API 620 Steel Oil Tank Bottom and Shell Support
The tank API 650 partially anchored liquid-storage tanks under-bottom insulation shall be designed to resist the combined pressures from the product load, the overturning seismic load and the vertical seismic load. These seismic pressures may be combined by SRSS.
The bearing ring under the shell shall be designed to resist the calculated OLE peak compressive force in the tank shell due to overturning (see API 650 oil tank, Section E.6.2.2), including dead and live loads. A 33 % increase in allowable bearing stress is permitted.

When talking about our team, it is hard not to mention our QC department (Quality Control). We have built strict qualitycontrol system to guarantee the steel quality. During the steel materials production, we have strict monitoring measures and indicators, and ensure no chemical composition, mechnical properties and so on technical problems for the steel materials API 650 partially anchored liquid-storage tanks. After production, our QC department will conduct another inspection regarding to the steel quantity, dimension, mark and so on points before delivery.

The company attaches great importance to logistics services, sets up our own transport truck fleet, improves customer response capacity through the improvement of logistics capacity, and further reduces costs. Customers ordering API 650 partially anchored liquid-storage tanks steel from our company can not only enjoy the service of fast delivery, but also enjoy lower transportation costs. Fast, accurate, simple and efficient has always been our principle.
