Fabrication requirements for API Std 650 carbon and low-alloy steel tanks

refrigerated tanks secondary components are those whose failure would not result in leakage of the liquid being stored. Secondary components also include those API Std 650 carbon and low-alloy steel tanks components that are not in contact with the refrigerated liquid but are subject to the refrigerated temperature vapors and have a combined tensile and primary bending stress under design conditions that does not exceed 6000 lbf/in.2. Secondary components that could be designed within this reduced stress are roof plates, including roof manways and nozzles with their reinforcement, roof-supporting structural members, and shell stiffeners.The API 650 petroleum storage tank standard is one of the most widely used design specifications. It is the API 650 standard of the American Petroleum Institute. The main goal of the API 650 standard is to promote the purchase and construction of vertical, above-ground, and welded manufacturing API Std 650 carbon and low-alloy steel tanks tanks through the requirements contained in its parts to ensure that the required safety regulations are met.Bangladesh is an important market to us. We cooperated with the National Railway, the National Tubes Limited (NTL) and so on state-owned enterprises. They have tenders regularly. And we would participate the tenders with our local agents. We have been the winner of NTL tenders for many times. API 5L grade B steel strips are their needed API Std 650 carbon and low-alloy steel tanks materials. They have special chemical composition, tolerance and so on requirements. We can fully meet their demands and guarantee timely delivery.Deformation of the welding seam of the API Std 650 carbon and low-alloy steel tanks is a common quality problem during the actual use of the API Std 650 carbon and low-alloy steel 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 Std 650 carbon and low-alloy steel 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.Relying on the background of high-quality steel resources and its own strong steel machining capabilities, BBN comany can not only supply various steel material products, such as steel coils, steel plates, API Std 650 carbon and low-alloy steel tanks sheet, steel pipes, and shaped steels, but also provide a variety of steel deep processing services like cutting, welding and grinding. Through continuous technological innovation and after-sales service optimization, the company has its own world on the domestic and international steel industry stage!
