API 650 flat-bottom tanks self-anchored

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.For areas with high groundwater levels, the operator should take anchoring and anti-floating measures for buried horizontal API 650 flat-bottom tanks oil tanks; API 650 oil tanks can be used for heavy fuel oil, heaters are separately designed, and buried tank material outlets are installed with bottom valves and connections. consider.In January 2019, one of our Vietnam customer purchased 395.62 tons Q345B steel plate API 650 flat-bottom tanks for their construction project, we prepared all the goods ready within 5 days, and supplied the goods with painting sand blasting to SA2.5 API 650 flat-bottom tanks and priming gray oxide primer, and arrange shipment in time. Meet the customer urgent delivery request.Comparison of the quality of mechanical cleaning and manual cleaning of vertical storage tanks, API 650 flat-bottom tanks. The mechanical cleaning of the API 650 flat-bottom tanks can make the inside of the tank be thoroughly cleaned in multiple directions, and the cleaning quality is high, and the cleaned oil does not contain lumpy impurities. While the walls and roof of the API 650 flat-bottom tanks cannot be cleaned in multiple directions during manual cleaning, and the cleaning quality is not easy to be guaranteed. The oily sewage collected after cleaning usually contains a lot of lumpy impurities, and these oil products are difficult to clean.Responsibilities: dealing with quality feedback and complaints from Customer.Bebon has the after sale service department, which is responsible to solve the problem of technical support and quality, service complaints.
