Mechanical loads on API 650 flat-bottom oil storage tanks
Welding inspection of bottom plate of API 650 flat-bottom oil storage tanks, vertical oil tank: During the fabrication and installation of API 650 flat-bottom oil storage tanks, the bottom edge plate is welded first. According to the requirements of the technical standard, penetrant inspection is required for the weld of edge plate at the bottom of API 650 flat-bottom oil storage tanks, that is, penetrant testing is required for each weld bead priming, filling and capping. In the process of testing, if any defect is found, it shall be repaired immediately. After the repair, the surface coloring penetrant test shall be conducted again until the test result is qualified.
Responsibility of API 620 Storage Tanks ExaminerThe inspector shall ensure that all materials used in tanks constructed according to the rules in this standard comply in all respects with the requirements of these rules. This shall be done either by witnessing mill tests or examining certified mill test reports supplied by the Manufacturer. Storage tanks API 650 flat-bottom oil storage tanks constructed according to the rules in this standard shall be inspected and tested in accordance with the sections that follow. The inspector shall carefully follow the fabrication and testing of each tank and shall make sure that they comply in all details with the design, fabrication, and tests specified in these rules.
Welding certification is regulated by Section 10 of the American Society of Mechanical Engineers (ASME). For both API 650 flat-bottom oil storage tanks storage tank API 650, non-destructive inspection is required, but third-party inspection is not required.
The formula of enterprise success is: success = strategy × organizational capability, that is, having the right direction and strong organizational capability. The core competence of an enterprise depends on three pillars: first, talents (talent echelon); second, core values of enterprise culture; third, organizational governance model. If the enterprise is a tree, then the core values of talents, corporate culture and organizational governance mode are just like the root of the tree. With them, the enterprise will flourish and grow forever.
