5086 aluminum shapes API 650 welded storage tanks

Hydrostatic Test
The API 650 welded storage tanks product shall be vented to the atmosphere when it is filled with or emptied of water. During water filling, the elevations of at least four equidistant points at the bottom of the tank shell and on top of the ringwall or slab shall be checked. Differential settlement, or uniform settlement of substantial magnitude, requires an immediate stop to water filling. Any further filling with water will depend on an evaluation of the measured settlement.

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 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.

To scientifically evaluate the remaining service life of the API 650 welded storage tanks, it is necessary to know the thickness change and development trend of the storage tank sheet after long-term use, combined with the metal characteristics of the storage tank, the influence of various external conditions and the continuous change of the oil pressure in the API 650 welded storage tanks, etc. factors to judge. Because the metal characteristics, corrosion defects, load and other numerical parameters of the API 650 welded storage tanks are randomly changed, the value of the remaining service life of the storage tank will also be dynamic.
