The foundations for API 650 open top welded storage tanks

Above the water level, all API 650 open top welded storage tanks welded joints, all welds around openings, and all piping joints against which the pneumatic pressure is acting shall be checked with a solution film. A visual inspection may be substituted for the solution-film inspection if the welded joint has previously been checked with a vacuum box. The solution-film inspection shall still be made, above the water level, on all welds around openings, all piping joints, and the compression ring welds, including the attachment to the roof and shell.

BBN excels in the design, fabrication and erection of API-650 tanks. API (American Petroleum Institute) has created a set of standards for above ground API 650 open top welded storage tanks oil storage, but these tanks are also commonly used for gasoline, chemical and water storage. API-650 storage tank solutions range in size from an 8’ -0” diameter shop fabricated tank up to and beyond 100’ -0” diameter field erected storage tank applications.

API 650 open top welded storage tanks construction must adhere to the design drawings, acceptance specifications and construction plans. If the design needs to be modified during API 650 open top welded storage tanks construction, it must be approved by the original design unit or Party A’s representative and relevant personnel of the supervision unit, and written visa procedures must be completed in advance. The equipment and main materials used in the oil tank construction project must have certificates of conformity and quality assurance.
