API 650 horizontal tank inspecting requirements

The outer FRP of API 650 oil tank will not produce electrolytic corrosion with groundwater and brine. The outer FRP will not corrode with gasoline, diesel oil and leaded gasoline API 650 horizontal tank. The leakage detector can monitor the whole process 24 hours to eliminate the potential pollution. The leakage detection system is convenient for the inspection and maintenance of API 650 oil tank, and protects the original ecological environment of soil and groundwater.

Foundations and subgrade shall safely carry the weight of the tank API 650 horizontal tank and its contents when the tank is filled with water to the highest level required for a hydrostatic test or other water-loading operations, even though the tank itself may be designed for some lesser density of liquid. However, in cases where the character of the soil justifies it and a competent soil expert advises it, allowance may be made for the relatively short duration and intermittent nature of the water loadings if suitable account is taken of all such loadings that may be expected to occur during the life of the tank, including not only those loadings that are incidental to periodic repetitions of the hydrostatic test in accordance with 7.18 but also water-filling operations for gas-freeing purposes.

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 horizontal tank 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 horizontal tank 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.
