API 650 SUG II tanks wind girders

The preparatory work before the construction of the API 650 SUG II tanks is an important part of the oil tank project. Material purchase preparation before the construction of the API 650 SUG II tanks:
Before API 650 SUG II tanks construction, all materials shall be purchased and prepared, and the specifications and quality of materials shall be inspected to see if they meet the construction operation requirements. Fire and rain proof measures should be taken when storing materials. Paint should be stored in a ventilated and dry place.

A cylindrical nozzle with a 12-in. inside diameter is located in solid plate in the sidewall of a cylindrical storage tank 60 ft in diameter so that its axis lies in a horizontal plane and forms an angle of 55° with a perpendicular to the sidewall at the point of intersection, as shown in Figure F-7. The thickness of the API 650 SUG II tanks sidewall plate, tw, in this area is 5/8 in., and no corrosion allowance is required. The total internal pressure, Pl + Pg, at the center of the opening is 26.1 lbf/in.2 gauge.

Fabricated to API standard 650 Welded Tanks for Oil Storage Shop Assembled API 650 SUG II tanks Storage Tanks, these tanks are commonly used at oil and natural gas terminals, API 650 SUG II tanks processing plants, and midstream facilities located along pipelines at the pumping, compression, or metering stations. API 650 storage tanks are designed and fabricated considering operating pressures up to 2.5 PSIG, corrosion allowance, wind loading, and seismicity.

Japan is a typical shipping first, and its raw materials are imported from Oceania, central and South America and other Asian countries. Most of the API 650 SUG II tanks steel produced is exported to China and other Asian countries, and a small amount is exported to America. Shipping is the main way of its API 650 SUG II tanks steel international transportation. According to the data, steel goods account for about 20% of the total sea freight in Japan. The domestic transportation of Japanese steel is mainly truck.
