API 650 flat-bottom steel tanks flush-stacked on the inside

In cylindrical tank walls, the longitudinal weld joints in adjacent shell courses, including compression ring welds, shall be offset from each other a minimum distance of 12 in. The butt-weld around the periphery of a thickened insert plate, or the fillet weld around the periphery of a reinforcing plate, shall be at least the greater of 10 times the shell thickness or 12 in. from any butt-welded seam or the bottom-to-shell or roof-to-shell joint. As an alternative, the insert plate (or the API 650 flat-bottom steel tanks reinforcing plate in an assembly that does not require stress relief) may extend to and intersect a flat-bottom-to-shell corner joint at approximately 90 degrees.Floating roof is the key component of floating roof API 650 storage tank, which can be divided into external floating roof and internal API 650 flat-bottom steel tanks floating roof. The internal floating roof has a fixed top cover above the floating roof, which can prevent the floating roof from being exposed to wind and rain, and ensure the quality of oil stored under API 650 storage tank.In 2016, we brought our customer to visit our NM400 hot rolled plate; producing line and our shanghai warehouse for 30,000 tons plate and structure. As a result, Our client purchased 500 tons NM400 as first order, which is shipped by 3 times. In future. Our company will always guarantee that all the delivery condition for Hardox plate API 650 flat-bottom steel tanks provided will be with quenching and tempering, which is the best delivery type according GB/T 24186 standard.In the petrochemical industry and other industries, large vertical API 650 flat-bottom steel tanks are often used to store various production raw materials. Usually, the medium with high melting point and easy to crystallize at room temperature can be exported and used after heating, which involves the heating of large vertical storage tanks. The heating system is an auxiliary facility for heating of large vertical storage tank. It is often necessary to design external heating coil or internal heating coil system.The company has passed the ISO9001: 2008 quality system certification, strictly implemented the ISO9001 quality management system. Besides, we have continuously improved the after-sales service network to make every effort to provide more convenient, accurate and faster services for all customers. We will supervise the production, control the quality in the factory, Inspect the cargo before shipment, Issue the test report to sales department. From the steel prodcution to steel delivery, we always focus the whole process.
