A662 Gr B plates API 650 carbon steel storage tanks

The elastic filling and sealing of floating roof API 650 carbon steel storage tanks is to fill the elastic and changeable objects in the sealed envelope, and the sealing purpose depends on the compression deformation of the filler. This kind of sealing effect is good, the requirement of the geometry of tank wall is not too high, and the adaptability is strong. However, the elastic filling and sealing has poor wear resistance and is easy to deform and damage in long-term use.

When as-rolled plate material complies with impact test requirements as specified here, the material need not be normalized. If, as with ASTM A516, the specification prohibits impact test without normalizing but otherwise permits as-rolled plates, the API 620 welded storage tanks material may be ordered in accordance with the above provision and identified as “MOD” for this API modification.

For areas with high groundwater levels, the operator should take anchoring and anti-floating measures for buried horizontal API 650 carbon steel storage tanks oil tanks; API 650 oil tanks can be used for heavy fuel oil, heaters are separately designed, and buried tank material outlets are installed with bottom valves and connections. consider.
