API standard 650 ground-supported liquid storage tanks supporting legs
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 ground-supported liquid storage tanks wall plate, t, required by 5.10.3 for the latitudinal unit forces, T2, acting at this level is 1.44 in.
There is a gap of 100 mm to 500 mm between the shell of API 650 crude oil storage API standard 650 ground-supported liquid storage tanks tank and the floating plate of external floating roof to ensure that there is no chuck during operation. Use API standard 650 ground-supported liquid storage tanks edge sealing system to reduce edge evaporation. The support legs of API 650 crude oil tank floating roof are usually movable and retractable and suspended in liquid.
The Egypt customer ordered 130 tons API standard 650 ground-supported liquid storage tanks stainless steel plate in stock, and this batch has left port today for its destination today(October 25th, 2019). 316l stainless steel is molybdenum-bearing austenitic stainless steel. This material has better corrosion resistant property than 304/314L for it's higher Ni and Mo content. (it is considered to be marine grade stainless steel, not suitable for warm sea water treatment). 316L austenitic stainless steel supplied by our company has good formability and weldablity, additionally it is proved to have excellent properties of tensile, creep and stress-rupture strengths in elevated temperature environment.
}Comparison of the quality of mechanical cleaning and manual cleaning of vertical storage tanks, API standard 650 ground-supported liquid storage tanks. The mechanical cleaning of the API standard 650 ground-supported liquid storage 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 standard 650 ground-supported liquid storage 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.
