API standard 650 horizontal tank tank shapes

Hydrostatic Test
The API standard 650 horizontal tank 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.

To provide customers with the most satisfactory service and realize the win-win of economic and social benefits, our company promises to provide excellent API standard 650 horizontal tank products in this bidding, and in line with the attitude of being serious and responsible to customers, before sending goods to users, the API standard 650 horizontal tank technical personnel shall confirm that there is no fault in the equipment before sending goods to users, and then send goods and products to users, and formulate the following service terms.

In Appendix E to API 650 oil storage tank, the maximum values of inertia force, pulse pressure and convection pressure are superimposed, and tend to be conservative.In GB50341, only pulse pressure is calculated for API standard 650 horizontal tank tanks below 5000 m.

To scientifically evaluate the remaining service life of the API standard 650 horizontal tank, 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 standard 650 horizontal tank, etc. factors to judge. Because the metal characteristics, corrosion defects, load and other numerical parameters of the API standard 650 horizontal tank are randomly changed, the value of the remaining service life of the storage tank will also be dynamic.
