API 650 cylindrical liquid-storage tank slab foundations

API 650 sets minimum requirements for the design, material, construction, and testing for aboveground, open and closed-top, cylindrical API 650 cylindrical liquid-storage tank steel storage tanks in different capacities and sizes, roughly equating to the pressure of the atmosphere (not greater than the weight of the roof plates).

Analyze the advantages and disadvantages of the products against the competitive products. Understand the industry situation and future trend. Understand the API 650 cylindrical liquid-storage tank product brand positioning appeal point, focus on the crowd and development direction. Understand the layout of each market area, and form a big strategic layout view. Understand the basic operation and assessment standards of work responsibilities. Understand the situation of the cooperative customers.

API 620 Steel Oil Tank Bottom and Shell Support
The tank API 650 cylindrical liquid-storage tank 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.

The after-sales service department will pay return visit to each customer by call or email, report problems found during the return visit in time, and discuss with the production and quality inspection center to propose effective solutions and follow up in a timely manner, so as to ensure the benefits each customer are fully guaranteed, and to provide customers with more value-added services.
