Seismic Use Group for API standard 650 ambient temperature tanks

,API standard 650 ambient temperature tanks., Oil tank is a large-scale storage equipment used to store oil materials. Usually, the service life of API standard 650 ambient temperature 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 standard 650 ambient temperature 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 standard 650 ambient temperature tanks?The tank 20-in. inside-diameter nozzle shown in Figure F-6 is located in solid plate in the sidewall of a cylindrical storage tank 148 ft in diameter in an area where the thickness of the wall plate, tw, is 11/2 in. A corrosion allowance of 0.10 in. is required on all surfaces of the tank exposed to the stored liquid. The total internal pressure, Pl + Pg, at the center of the opening is 24.9 lbf/in.2 gauge. The thickness of the API standard 650 ambient temperature tanks wall plate, t, required by 5.10.3 for the latitudinal unit forces, T2, acting at this level is 1.44 in.According to API Standard 650, the stairs used for API 650 petroleum storage tanks or thermal insulation tanks should be double longitudinal beams supported by a minimum of ribs. If the gap between the API standard 650 ambient temperature tanks tank shell and the stringer of the API 650 petroleum storage tank exceeds 200mm, handrails should be provided on both sides of the stairs. Unless otherwise specified, according to API standard 650 ambient temperature tanks ASTM A123, the following accessories shall be hot-dip galvanized. The damaged zinc coating should be repaired with zinc alloy.In order to better develop the international steel market and make the steel products trade more prosperous at home and abroad, the company has a number of professional talents who love their posts and are proficient in their business.
