API Std 650 austenitic stainless steel storage tanks isolation valves
The floating roof is the top cover floating on the liquid level, so the sealing performance of API Std 650 austenitic stainless steel storage tanks 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 Std 650 austenitic stainless steel storage tanks floating plate is lowered to a certain position of about 1.8m, a prop will support the floating plate to keep it in position.
Oil storage tank with floating roof structure: The floating roof in the API Std 650 austenitic stainless steel storage tanks oil storage tank can effectively reduce the volatilization consumption of oil, because the gas space on the oil liquid surface in the floating roof storage tank is small, the exhaust volume is low, and the breathing loss is very small. That can reduce the volatilization loss caused by the "big breath" of the API Std 650 austenitic stainless steel storage tanks. Strengthen the inspection and maintenance of API Std 650 austenitic stainless steel storage tanks: regularly check the sealing conditions of oil storage tanks, and check and maintain important auxiliary equipment to ensure good sealing performance.
The horizontal projection of the roof plate within the compression-ring region is 4.9 x 0.866 = 4.25 in., which fulfills the requirement of API 620 tank standard 5.12.5.1. The required area and horizontal projection can be provided by any of the standard angles listed in Table F-3.Any of these angles may be used in accordance with the details of Figure 5-6, detail a or b, but if details c, h, or i in Figure 5-6 were intended, the net area of the angle must be calculated by deducting the area expected to be lost by corrosion from that part of the angle surface that is exposed to the interior of the tank.

As steel transportation belongs to the transportation of major parts, so in the process of transportation, modern logistics technology, such as centralized transportation, information technology, is a bit out of place. Based on the current situation of China's API Std 650 austenitic stainless steel storage tanks steel transportation industry, highway transportation is a way of transportation that many enterprises often choose. Naturally, its business volume also accounts for more than 50% of the whole API Std 650 austenitic stainless steel storage tanks steel transportation industry.
