API standard 650 welded steel oil storage tanks liquid penetrant examination
Fixed roof API 650 oil storage tank includes inner floating roof tank, which API standard 650 welded steel oil storage tanks can effectively prevent sand, rain, snow or dust from polluting the storage liquid. Under various weather conditions, API 650 oil storage tank can ensure the quality of liquid storage, which is called "all-weather API standard 650 welded steel oil storage tanks storage tank".
Manufacturer’s Report and CertificateUpon completion of all tests and inspections on each tank API standard 650 welded steel oil storage tanks, the Manufacturer shall prepare a report summarizing all the data on the tank, including foundations (if they are within the Manufacturer’s scope of responsibility) and shall attach to the report all drawings and charts as required by other paragraphs in this section of the rules (see API 620 tank 7.13 and Appendix M).The tank Manufacturer shall furnish and fill out a certificate for each tank (such as that shown in Appendix M), attesting that the tank has been constructed according to the rules in this standard. This certificate shall be signed by the Manufacturer and the Purchaser’s inspector. This certificate, together with the nameplate or markings placed on the tank, shall guarantee that the Manufacturer has complied with all applicable requirements of these rules.
When the API standard 650 welded steel oil storage tanks is welded, the weldment should be fixed rigidly. After welding, when the weldment is cooled to normal temperature, the rigid fixation can be removed, which can effectively prevent angular deformation and wave deformation. Although some measures have been taken, the welding deformation of API standard 650 welded steel oil storage tanks is still unavoidable, so it is necessary to take corrective measures to compensate the deformation. Mechanical correction is to make the parts easy to deform in the welding process by mechanical or other rigid materials to produce simple deformation, so as to restore the state before welding.

The trend of international shipping development of large-scale ships and strategic joint ventures puts forward higher requirements for modern ports. Modern ports no longer use the general cargo throughput as a measure sign, and container throughput will become the main sign to measure the role and status of modern ports. The average container capacity in 2000 is 3200teu, and it is expected to be 5500teu in 2020.
