API Std 650 mechanically-anchored tanks level gauge
In order to prevent the deformation of the bottom of metal vertical storage tank, API Std 650 mechanically-anchored tanks during welding, the number of welders should be reasonably distributed. When welding metal vertical API Std 650 mechanically-anchored tanks, personnel and welding position shall be reasonably allocated according to the actual situation of welding personnel, and random welding is not allowed.In this project, an elemental area of API 620 oil storage tank wall is constructed of ASTM A516 Grade 55 steel plate subjected to a meridional unit force, T1, of 2620 lbf/in. tension and a latitudinal unit force, T2, of 2880 lbf/in. compression. The meridional radius of curvature, R1, is 132 in., and the length of the normal from the surface to the axis of revolution, R2, is 409 in. The joints in the wall are spot-radiographed, double-welded butt joints, and no corrosion allowance is required.The problem in this example is to graphically find the minimum thickness of tank wall required for the given conditions (see API 620 tank standard 5.10.3.3).Solution: As determined from Table 5-1, the maximum, allowable tensile stress value, Sts, for ASTM A516 Grade 55 steel plate in simple tension is 16,500 lbf/in.2. Since the compressive stress is latitudinal, the governing value of R for this situation is R1, or 132 in.API 650 storage tank is used for commonly used oil, gasoline, diesel, chemical and production water storage. API Std 650 mechanically-anchored tanks Storage tanks built to these standards are spread across U.S. refineries, terminals, pipelines, and production facilities. The API 650 detailed standard specifies the design, processing, welding, inspection and installation procedures for storage tanks.The company revolves around the long-term strategy of "building a quality base and building a century-long BEBON", adheres to the development ideas of innovation, transformation, and improvement, vigorously promotes transformation and upgrading, structural adjustment, energy conservation and emission reduction, and strives to create high-quality steel with strong core competitiveness and distinctive features The production base has become a green steel city with intensive land use, clean production, efficient use of resources, harmonious and friendly production and environment, business and society, and BEBON characteristics.The company has accumulated rich experience in long-term cooperation with new and old customers, which makes our products API Std 650 mechanically-anchored tanks more unique in the same industry, and is favored and praised by users.
