API 650 mechanically-anchored steel tanks foundations for elevated temperature service
This specification, in conjunction with API 650 Standard, prescribes minimum standards for the API 650 mechanically-anchored steel tanks design, supply fabrication, erection, and testing of field erected welded steel storage tanks complete with accessories as specified herein and as shown on attached datasheets and/or drawings.
X-ray inspection is mainly applicable to the internal inspection of pressure bearing parts and materials of metal oil tanks such as API 650 mechanically-anchored steel tanks. It can clearly find the blocky defects inside the welded joints. However, the cost and resource consumption of radiographic testing are large. Magnetic particle testing can effectively detect the surface and near surface defects of API 650 mechanically-anchored steel tanks etc. metal oil tanks, but magnetic particle testing can not effectively identify the internal defects of oil tanks.
Foundations and subgrade shall safely carry the weight of the tank API 650 mechanically-anchored steel tanks 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.
The technology center has always been focusing on application research, improving market realization and scientific and technological contribution rate; taking user demand as the goal, highlighting the personalized development of products; taking the joint development of industry, University and research, and technology integration as the means, improving the starting point and level of innovation, and realizing the breakthrough of core technology; taking advanced research as the guide, pursuing the leap of technological development; taking system and mechanism innovation as the driving force, Promote and realize the working concept of technological innovation.
Iron and steel goods, including pig iron, ingots, all kinds of steel and so on. Therefore, logistics companies are required to load evenly and evenly in the process of transportation, prevent moisture and prevent corrosion. It is necessary to prevent the API 650 mechanically-anchored steel tanks steel sheet from being mixed with water when transporting the steel; it is necessary to prevent the API 650 mechanically-anchored steel tanks steel from being mixed with water when transporting the steel; it is necessary to prevent the steel from being mixed with water when transporting the steel; it is necessary to prevent the steel from being mixed with water when transporting the steel; it is necessary to prevent the steel from being mixed with water when loading the API 650 mechanically-anchored steel tanks steel sheet on the truck Good luck.
