Optional design procedures of API 650 aboveground petroleum storage tanks
For open top and fixed roof API 650 tanks, the net working capacity is the liquid volume contained between the minimum operating level (top of API 650 tanks API 650 aboveground petroleum storage tanks outlet connection) and the maximum operating level [limited to the bottom of overflow connection, 75 mm below foam chamber connection, or 150 mm below rim, whichever is greater.
The company has passed the ISO9001: 2008 quality system certification, strictly implemented the ISO9001 quality management system. Besides, we have continuously improved the after-sales service network to make every effort to provide more convenient, accurate and faster services for all customers. We will supervise the production, control the quality in the factory, Inspect the cargo before shipment, Issue the test report to sales department. From the steel prodcution to steel delivery, we always focus the whole process.
The API 650 oil tank stiffener ring and backing strip, if used, are primary components, and they shall comply with the requirements of R.2.1. The API 650 aboveground petroleum storage tanks stiffener ring may be fabricated from plate using an intermittent weld on alternating sides between the web and the flange. One rat hole with a minimum radius of 3/4 in. shall be provided at each longitudinal shell joint and ring juncture weld.
Safety comparison between mechanical cleaning and manual cleaning of vertical storage tank, API 650 aboveground petroleum 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 aboveground petroleum 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.
