ISO 630 Gr E275D plates API Std 650 self anchored flatbottom tanks

API Std 650 self anchored flatbottom tanks any joints between the adjacent sections of stiffening rings, as shown in Figure R-1, shall be made so that the required moment of inertia of the combined ring-shell section is provided. Weld joints between adjacent sections shall be made with full-thickness and full-penetration butt-welds. Stiffening-ring butt-welds may employ metal backing strips. Backing strips and the associated welding shall be made in a manner that provides a smooth contour in the rat hole and all other weld joints ends. All weld passes shall be started at the rat hole.

Structural features of API 650 double-layer oil tank: steel glass fiber reinforced plastic double-layer structure, special processing method is adopted between the API Std 650 self anchored flatbottom tanks internal steel shell and glass fiber reinforced plastic layer, so that a gap of 0.1 mm is created between the internal and external layers. Even if the API 650 oil storage tank leaks, it can ensure that the contained dangerous substances only flow in the gap, and will not immediately overflow the external environment.

With the fast development in Myanmar, Myanmar navy build frigate every year. Bebon Cooperate with Myanmar Navy from from 2015. They purchased 412 ton API Std 650 self anchored flatbottom tanks LR AH36 steel plate from Bebon as trial order in 2015. After receiving the goods, they speak highly of the quality and bebon's service. After that they purchase the shipbuilding steel plate from bebon regularly. In May,2018, the Myanmar navy's local representative visit our office and production line, and sign another contract 2025 tons API Std 650 self anchored flatbottom tanks LR A shipbuilding steel plates order in our office.

To scientifically evaluate the remaining service life of the API Std 650 self anchored flatbottom tanks, it is necessary to know the thickness change and development trend of the storage tank sheet after long-term use, combined with the metal characteristics of the storage tank, the influence of various external conditions and the continuous change of the oil pressure in the API Std 650 self anchored flatbottom tanks, etc. factors to judge. Because the metal characteristics, corrosion defects, load and other numerical parameters of the API Std 650 self anchored flatbottom tanks are randomly changed, the value of the remaining service life of the storage tank will also be dynamic.

We should focus on the main problems to be solved and pay attention to efficiency. After receiving the user's quality objection report data, the possible causes, responsible units, compensation amount, etc. of the problem shall be judged based on experience. To have a clear service plan, to be clear about what your main problem is, what technical support is needed, these should be prepared.
