Elastic displacements of API 650 self-anchored tank

Compared with the fixed roof API 650 oil storage tank without API 650 self-anchored tank floating roof, there is no evaporation space. In principle, this eliminates the so-called "large breathing loss". Evaporation not only causes the loss of product quantity, but also affects the quality of API 650 self-anchored tank product and pollutes the environment.

API 650 self-anchored tank test procedure
The inner tank shall be opened to the atmosphere, and a sufficient amount of water shall be added to the inner tank to balance the upward pressure against the inner tank bottom produced by the pneumatic test of the outer tank; as an alternative, the pressure between the inner and outer tanks can be equalized. API Standard 620 Air pressure shall be applied to the space enclosed by the outer tank equal to at least the design gas pressure but not exceeding a pressure that would overstress either the inner or outer tank.

Before welding the API 650 self-anchored tank, the professional skills of the welding personnel shall be fully assessed to ensure that the operators meet the corresponding welding qualifications. According to the technical standards, scientific and feasible process requirements are actually formulated. In the process of welding the edge plate of API 650 self-anchored tank, electric welding is required on one side of the edge plate, so that the edge plate has a free shrinkage effect and greatly reduces the residual stress of the welding seam.
