API standard 650 mechanically-anchored flat-bottom tanks qualification of welding procedures
After the API standard 650 mechanically-anchored flat-bottom tanks is manufactured, air tightness test and water filling test are carried out according to the design requirements, and the pipeline must be subjected to pressure test to fully meet the acceptance technical specifications. Improve the quality assurance system, adhere to the principle of who constructed is responsible for the quality of the project, conduct regular quality inspections, and immediately rectify any problems. Fill in the API standard 650 mechanically-anchored flat-bottom tanks installation technical records in time to ensure the synchronization, integrity and reliability of the technical data.
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 mechanically-anchored flat-bottom 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.
