Foundation loading data of API Std 650 flexible liquid storage tanks

API 650 tank has the advantages of less load on the floating plate, simple and light structure, and can save the central drainage pipe and rotating floating ladder on the API Std 650 flexible liquid storage tanks floating plate. The materials for easy construction and maintenance and sealing parts can avoid aging due to sunlight.

The cost of mechanical cleaning for vertical storage tank, API Std 650 flexible liquid storage tanks is low, almost all oil can be recovered, and the quality of recovered oil is high. The cost of manual cleaning for vertical storage tank, API Std 650 flexible liquid storage tanks is high, the oil can not be recovered completely, and the quality of recovered oil is low. The mechanical cleaning of API Std 650 flexible liquid storage tanks adopts fully enclosed operation, and separates oil, water and oil sand. There is no direct discharge of oily sewage and waste gas, which will not pollute the environment.

The API Std 650 flexible liquid storage tanks stiffener ring and backing strip (if used) are primary components, and they shall comply with the requirements of API 620 storage steel tank Q.2.1. The stiffener rings may be fabricated from plate using an intermittent weld on alternating sides between the web and the flange.
Except for aluminum or stainless steel tanks, all fillet welds shall consist of a minimum of two passes. The ends of the fillet welds shall be 2 in. from the rat hole (see Figure Q-1), and these welds shall be deposited by starting 2 in. from the rat hole and welding away from the rat hole. An acceptable alternative to the detail that includes stopping fillet welds 2 in. short of the rat hole would be to weld continuously through the rat hole from one side of the stiffener to the opposite side. All craters in fillet welds shall be repaired by back welding.
