A516 Gr 415 plates API 650 welded steel storage tanks
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 650 welded steel storage 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 650 welded steel storage tanks ASTM A123, the following accessories shall be hot-dip galvanized. The damaged zinc coating should be repaired with zinc alloy.
Pressure Setting of Safety DevicesExcept as provided in API 620 tank 9.5 for certain liquid relief valves, the pressure setting of a pressure-relieving device shall in no case exceed the maximum pressure that can exist at the level where the device is located when the pressure at the top of the tank equals the nominal pressure rating for the tank (see API 620 tank 5.3.1) and the liquid contained in the tank API 650 welded steel storage tanks is at the maximum design level.Vacuum-relieving devices shall be set to open at such a pressure or partial vacuum that the partial vacuum in the tank cannot exceed that for which the tank is designed when the inflow of air (or other gas or vapor) through the device is at its maximum specified rate.
Safety comparison between mechanical cleaning and manual cleaning of vertical storage tank, API 650 welded steel storage tanks. Closed cleaning is adopted for mechanical cleaning. During the cleaning process, operators are not required to enter the tank. The inert gas space formed in the storage tank can prevent the occurrence of fire, explosion and other accidents. When the API 650 welded steel storage tanks is manually cleaned, the operators should directly enter the tank for cleaning, threatening the health of employees, and there is no inert gas space in the tank, which is prone to fire and explosion accidents.

The mode of iron and API 650 welded steel storage tanks steel logistics transportation is mainly intercontinental ocean shipping and inland rail transportation. European ports have been very mature after years of development, such as Hamburg in Germany, Rotterdam in the Netherlands and Antwerp in Belgium. Relying on the huge market of the European Union, these ports are positioned in the logistics distribution function of cargo distribution and large import and export, and play a great role in the transportation of API 650 welded steel storage tanks steel logistics.
