5154 aluminum pipe API standard 650 stainless and carbon steel tank
The floating roof is the top cover floating on the liquid level, so the sealing performance of API standard 650 stainless and carbon steel tank API 650 oil storage tank is very important. The floating plate mainly adopts elastic packing, and at the same time, it is compressed with the wall of API 650 oil storage tank with pressure strip around, and fixed with the floating plate with bolts. After the API standard 650 stainless and carbon steel tank floating plate is lowered to a certain position of about 1.8m, a prop will support the floating plate to keep it in position.
The insert plate weld shall not cross any shell seams and shall be at least the greater of 10 times the shell thickness or 12 in. from any other weld in the API standard 650 stainless and carbon steel tank shell including shell seams, shell-to-bottom weld or attachment welds. The butt weld around the periphery of the plate shall be examined over 100% of its length by both liquid penetrant method and radiographic method. The liquid penetrant examination is required on the root pass, on the back-gouged surface, and on the inside and outside finished weld surfaces. Additionally, the weld shall be vacuum box leak tested.
Due to the volatility of oil products, the volatile consumption of oil products is inevitable in the storage process of large oil storage tanks such as API standard 650 stainless and carbon steel tank. The volatilization of oil causes economic losses and pollution to the environment. Especially in the open air environment, large-scale oil storage tanks in the petrochemical industry will continue to accumulate energy when exposed to the sun, causing their surface and interior to heat up rapidly, causing sun overheating, and accelerating the volatilization of oil. How to effectively reduce the volatile consumption of large oil storage tanks?
