In order to ensure the safety of the vertical storage tank, API 620 flat-bottomed tanks shell, the supplier should inspect the tank carefully before delivery. The failure of the tank body is mainly due to the weld and crack of the product. The inspection of API 620 flat-bottomed tanks shell, vertical storage tank weld and microcrack is mainly to inspect the appearance forming quality of weld. The inspection contents include weld leg height, undercut, welding deformation, weld bead, arc pit, weld straightness, etc., as well as the internal quality of weld, such as slag inclusion, porosity, incomplete penetration, crack, incomplete fusion, etc.

The company conducts periodic and targeted training and guidance for after-sales service personnel. As the saying goes, "no one is perfect, no gold is red", to help after-sales service personnel improve service skills and correct service attitude.

API 620 flat-bottomed tanks shell 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.
