Steel plate for shells of API standard 650 aboveground oil storage tanks

Deformation of the welding seam of the API standard 650 aboveground oil storage tanks is a common quality problem during the actual use of the API standard 650 aboveground oil storage tanks, which easily causes the tank body to leak and affects the safety of the oil storage tank. The welding seam deformation of the API standard 650 aboveground oil storage tanks is mainly caused by the lack of reserved welding seam gap and irregular operation. The oil storage tank has not reserved the corresponding weld gap, resulting in deeper root removal during the front welding activity. The heat output of the weld will increase under the influence of a long time, and the deformation of the weld will gradually become serious.The horizontal projection of the roof plate within the compression-ring region is 4.9 x 0.866 = 4.25 in., which fulfills the requirement of API 620 tank standard 5.12.5.1. The required area and horizontal projection can be provided by any of the standard angles listed in Table F-3.
Any of these angles may be used in accordance with the details of Figure 5-6, detail a or b, but if details c, h, or i in Figure 5-6 were intended, the net area of the angle must be calculated by deducting the area expected to be lost by corrosion from that part of the angle surface that is exposed to the interior of the tank.API 650 internal floating roof oil tank executive standard: domestic design standard: GB50341-2003 "Vertical cylindrical steel welded oil tank design code"; domestic construction standard: GB50128-2005 "vertical cylindrical steel welded oil tank" Construction and Acceptance Specification; API standard 650 aboveground oil storage tanks Foreign design standard: API650-2007 "Standard for Welded Steel Petroleum Storage Tanks."With the development of China's market economy, the company vigorously implements the strategy of industrialization, internationalization and diversification, promotes the group operation, intensive development and lean management, and through a rich series of products and project portfolio as well as a complete operation network, Build the company into a modern enterprise with scientific development concept, continuous innovation vitality, excellent corporate culture, strong sense of social responsibility and international first-class competitiveness.Expect in the API standard 650 aboveground oil storage tanks goods regardless quality be still on the price after-sales service we all will keep in the middle of go together of advantage position real attain the ream customer satisfaction.Our advantage is: experienced craftsmen API standard 650 aboveground oil storage tanks product development technology, excellent production team, hand strict quality control, sales and after-sales service.
