API standard 650 anchored liquid-storage tanks seal membrane

The vent pipe mouth should be 4m or more above the ground. The nominal diameter of the API standard 650 anchored liquid-storage tanks API 650 petroleum storage tank vent pipe should be no less than 50mm and a flame arrestor should be installed.

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.

The construction period comparison of mechanical cleaning and manual cleaning for vertical storage tank, API standard 650 anchored liquid-storage tanks. The API standard 650 anchored liquid-storage tanks mechanical cleaning period is short, and the construction period is not affected by the size of the storage tank and the amount of sludge in the tank, and the cleaning equipment operates 24 hours a day. The manual cleaning of the API standard 650 anchored liquid-storage tanks has a long construction period, which is easily affected by the external environment, and the number of workers is limited by the size of the storage tank and the amount of sludge.

Safety production is the cornerstone of enterprise survival and development. The company established a safety management network, which achieved clear powers and responsibilities, clear responsibilities, effective management and control, and provided organizational guarantee for safe production. The company strictly complies with the "Environmental Protection Law", establishes an effective environmental protection emission control system and waste gas, waste water, waste solid recycling system, and makes great efforts to harden, lighten, green, and beautify the plant, and strive to build green steel enterprises.

Japan is a typical shipping first, and its raw materials are imported from Oceania, central and South America and other Asian countries. Most of the API standard 650 anchored liquid-storage tanks steel produced is exported to China and other Asian countries, and a small amount is exported to America. Shipping is the main way of its API standard 650 anchored liquid-storage tanks steel international transportation. According to the data, steel goods account for about 20% of the total sea freight in Japan. The domestic transportation of Japanese steel is mainly truck.
