Internal floating roof API 650 mechanically-anchored flat-bottom tanks
This specification, in conjunction with API 650 Standard, prescribes minimum standards for the API 650 mechanically-anchored flat-bottom tanks design, supply fabrication, erection, and testing of field erected welded steel storage tanks complete with accessories as specified herein and as shown on attached datasheets and/or drawings.
The API 650 mechanically-anchored flat-bottom 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.
Oil storage tank is an important equipment commonly used in petroleum and petrochemical industry. New API 650 mechanically-anchored flat-bottom tanks, metal storage tank must be tested before it can be put into use or put into storage. The common inspection methods of API 650 mechanically-anchored flat-bottom tanks include radiographic testing, ultrasonic testing, magnetic particle testing and dye penetrant testing. The parts and operation requirements of these testing methods are different, so they should be selected according to the required characteristics.
