Quality inspection of API standard 650 duplex stainless steel tanks
According to API 650 tanks, anchoring devices should be designed to transfer overturning moments to the API standard 650 duplex stainless steel tanks tank foundation. At the same time, according to API 650 tank Appendix F, when the tank is to be anchored, the size of the anchoring parts is determined by the maximum lifting force caused by the internal pressure and wind load or the combination of internal pressure and seismic load.
Surface Inspection of low-pressure storage tank Component PartsBefore assembly, unless already so certified by shop inspectors, all sidewall plates or sections and roof and bottom plates shall be inspected for thickness, freedom from injurious defects, and soundness of any welded joints.Check of Dimensions of API standard 650 duplex stainless steel tanks Component PartsAll formed plates and curved sections shall be checked for conformance with the planned dimensions and cross section. For unusual repairs the inspector should keep a record of measurements taken at sufficient intervals to constitute a satisfactory record.Check of Chemical and Physical Property DataThe inspector shall check the material being assembled by the lists of the plates from the mill, their heat numbers, chemical analyses, and mechanical properties as given on mill reports and shall see that copies are available to be attached to the Manufacturer’s report.
Welding inspection of bottom plate of API standard 650 duplex stainless steel tanks, vertical oil tank: During the fabrication and installation of API standard 650 duplex stainless steel tanks, the bottom edge plate is welded first.
