A516 grade 70 plates API standard 650 welded aluminum storage tanks

The standard API 650 covers the design and calculation of different parts of the API standard 650 welded aluminum storage tanks fuel tank. This specification is based on the knowledge and experience of buyers, manufacturers and users of API 650 welded storage tanks of different sizes and capacities. It is worth noting that the code requirements are minimal; stricter standards can be adopted for specific applications.

Inspection of weld and micro crack of API standard 650 welded aluminum storage tanks: the inner and outer surface of API standard 650 welded aluminum storage tanks, weld and heat affected zone shall be observed by naked eyes first. 100% ultrasonic testing or 100% penetrant testing are carried out for butt welds of API standard 650 welded aluminum storage tanks. For the defects found by 100% magnetic particle inspection, dye detection, 100% ultrasonic inspection or 100% penetrant inspection, the radiographic inspection shall be used again to ensure the accuracy of the test results.

API 620 Steel Oil Tank Bottom and Shell Support
The tank API standard 650 welded aluminum 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.

The shipping department of the company arranges shipping booking for customers' goods in advance, and makes good matching with inland transportation. Effectively manage and follow up the customer's shipping schedule and give feedback to customers in time. At the same time, the shipping department has a keen insight into the shipping market in different periods to reduce the transportation cost for the company and customers.

In particular, the EU imports a large amount of iron ore from central and South America and Oceania, which are mainly transported by sea. The perfect port infrastructure makes the port operation cost of EU iron ore raw materials import relatively low. However, the API standard 650 welded aluminum storage tanks steel transportation between EU Member States is mainly railway transportation, and the EU member states have established a very developed railway network and railway information infrastructure.
