Storage Tanks Inspection Services (API 650 and API 653)
Manufacturing and assembly inspection of atmospheric storage tanks according to API 650 standard is carried out under the supervision of API Authorized inspector. All inspection activities are accredited and reported.
Storage Tanks are provided with 3-stage service.
Design Control; Taking into account the requirements of the technical drawing, calculation and design specifications (wind load, snow load, earthquake load) submitted to us, the design is checked by the API 653 Authorized Inspector and “Design Examination Report” is published.
Manufacturing Control; Welding and manufacturing controls are carried out according to the quality plan to be created in the factory where the storage tank and pipe spools are made. NDT controls are supervised. After the controls, the “Inspection report” is published.
Field Assembly Control; The “Inspection Report” is published after the welding and assembly controls, by checking whether the productions shipped to the assembly site are assembled according to the approved projects.
During the commissioning process, the tests are supervised and the requirements of the specification and API standards are checked. If the whole process is successful, API 650 certificate is given.
