API Std 650 aboveground welded storage tanks bottom-transition plate

,API Std 650 aboveground welded storage tanks., Oil tank is a large-scale storage equipment used to store oil materials. Usually, the service life of API Std 650 aboveground welded storage tanks is related to the actual working conditions. The design service life of most oil tanks is 20 years, and some of them are 10-15 years. Generally, none of them is less than 10 years. However, the design service life of API Std 650 aboveground welded storage tanks is on the one hand, which is an ideal state, but there are many objective factors in the actual process, it is impossible to achieve the designed service life. How to effectively increase the service life of API Std 650 aboveground welded storage tanks?API Std 650 aboveground welded storage tanks any joints between the adjacent sections of stiffening rings, as shown in Figure R-1, shall be made so that the required moment of inertia of the combined ring-shell section is provided. Weld joints between adjacent sections shall be made with full-thickness and full-penetration butt-welds. Stiffening-ring butt-welds may employ metal backing strips. Backing strips and the associated welding shall be made in a manner that provides a smooth contour in the rat hole and all other weld joints ends. All weld passes shall be started at the rat hole.For floating roof API 650 tanks, the net working capacity is the liquid volume contained between the API Std 650 aboveground welded storage tanks maximum operating level (300 mm below rim for metallic type seals and 600 mm below rim for fabric type seals) and the minimum operating level (API 650 tanks roof supports clearing the tank bottom by 25 mm while set at the operating position).Enterprise mission: to create value added steel products API Std 650 aboveground welded storage tanks and provide first-class serviceWe are committed to quality. It is to firmly establish the concept that quality is the life of an enterprise, and make it clear that quality is the decisive factor for the survival and development of an enterprise. Adhere to the quality brand strategy and strive to improve the comprehensive competitiveness with quality as the core.Core values of the enterprise: innovation, dedication and transcendence. It is a highly refined spiritual quality to our staff.The company has sufficient stocks and complete specifications. The common carbon steel plates, marine plates, API Std 650 aboveground welded storage tanks and storage tank steel plates sold are all produced by large state-owned steel companies such as Shougang, Hegang, Taiyuan Iron and Steel, with quality assurance and worry-free after-sales. The company develops and grows under the concept of seeking innovation in stability and advancing with the times for development. After a short period of development, it has begun to take shape.
