API Std 650 aboveground petroleum storage tanks shell-to-bottom welds

API 650 petroleum storage tank basic knowledge, storage tank concept and use: API Std 650 aboveground petroleum storage tanks storage equipment for storing crude oil, gasoline, kerosene, petroleum and various non-volatile chemicals, API 650 petroleum storage tank is a storage and transportation system facility, oil refining, chemical industry An important part of the device.

The API Std 650 aboveground petroleum 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.

The structure of the API Std 650 aboveground petroleum storage tanks foundation mainly includes the insulating anticorrosion layer on the top surface of the foundation, the tank wall support, the edge retaining structure, the sand cushion, the oil and water barrier, the detection signal tube and other structures. The construction materials and requirements of each basic structure of the storage tank are different. After the structure of the API Std 650 aboveground petroleum storage tanks foundation is built in accordance with the construction requirements, the settlement of the storage tank foundation needs to be observed, and the uneven settlement value of the storage tank foundation should be within the allowable safety range.
