API standard 650 vertical welded storage tanks design metal temperature

Our team is a dynamic, but also mature and steady team. The talents are made of different ages. There are experienced ones, and also creative ones, that also makes our company culture diversified. We have complete department structure, to make the whole work procedure run smoothly. For every step, we have special person to be in charge and responsible for our customer and update information to the customer in time. So you just need not worry too much to purchase steel materials from our company.In this project, an elemental area of tank wall used is constructed of ASTM A442 Grade 55 steel plate subjected to a meridional unit force, T1, of 4000 lbf/in.2 tension and a latitudinal unit force, T2, of 5060 lbf/in.2 compression. The meridional radius of curvature, R1, is 75 in., and the length of the normal from the surface to the axis of revolution, R2, is 300 in. The joints in the wall are of double-welded butt-joint construction with a tensile efficiency of 85%. A corrosion allowance of 1/16 in. is required.
The problem in this example is to graphically find the minimum thickness of tank wall required for the given conditions (see 5.10.3.3).
Solution: As determined from Table 5-1, the maximum allowable tensile stress value, Sts, for ASTM A442 Grade 55 steel plate in simple tension is 16,500 lbf/in.2. Since the compressive stress is latitudinal, the governing value of R in this situation is R1, or 75 in.API 650 stipulates that an open tank should be provided with a wind-resistant ring to ensure that the API standard 650 vertical welded storage tanks tank body maintains its roundness when subjected to wind. There are no hard and fast rules for vault API 650 storage tanks. It can be determined by comparing the equivalent wall height with the maximum height of the unreinforced tank wall.The company always insists on quality first. "Tolerance and trust, change and innovation, abide by rules, and focus on refining people" are the eternal credo of the team. Encouraged by the same creed and belief, BEBON people continue to grow and mature, and the team size is increasing expand. In the future, look beyond Chinese private steel companies to see BEBON. Looking to the future, we are not blindly pursuing bigger scale, but we are pursuing strength and brand strength.Oil tank is an important equipment for oil storage. The common API standard 650 vertical welded storage tanks is composed of foundation, bottom plate, wall plate, top plate and accessories. The types of oil tank are various, which can be divided according to the characteristics of material, installation position, storage oil, use, appearance, structure and volume of oil tank. The commonly used materials of metal oil tank are stainless steel, carbon steel, alloy steel, etc.
