Quality inspection of API 650 mechanically-anchored flat-bottom tanks

storage tanks API 650 mechanically-anchored flat-bottom tanks built to these standards are spread across U.S. refineries, terminals, pipelines, and production facilities. The API 650 petroleum storage tank detailed standard specifies the design, processing, welding, inspection and installation procedures of the storage tank.

Personnel organization before the construction of the API 650 mechanically-anchored flat-bottom tanks:
The company shall select technical personnel, quality inspectors and material personnel with organizational ability and construction management experience to participate in the API 650 mechanically-anchored flat-bottom tanks project construction. The construction personnel shall arrive at the construction site before the designated commencement date, investigate the construction site, build construction facilities, plan the construction steps, and analyze the potential safety hazards during operation.

In cylindrical tank walls, the longitudinal weld joints in adjacent shell courses, including compression ring welds, shall be offset from each other a minimum distance of 12 in. The butt-weld around the periphery of a thickened insert plate, or the fillet weld around the periphery of a reinforcing plate, shall be at least the greater of 10 times the shell thickness or 12 in. from any butt-welded seam or the bottom-to-shell or roof-to-shell joint. As an alternative, the insert plate (or the API 650 mechanically-anchored flat-bottom tanks reinforcing plate in an assembly that does not require stress relief) may extend to and intersect a flat-bottom-to-shell corner joint at approximately 90 degrees.

We have Business Department, Transportation Department, Document Department, Shipping Department, E-C department, Procurement Department, Finance Department, Human Resources Department, Administration Department, Logistics Department, After-sales so on Departments.
