API 650 cylindrical tanks fixed legs

API 650 petroleum storage tank has the advantage of long economic life: because there is no gas space on the liquid surface in the internal floating roof API 650 cylindrical tanks storage tank, the vibration generated during the transportation of liquid inside and outside the tank is reduced.

The API 650 cylindrical 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.

How to effectively increase the service life of API 650 cylindrical tanks oil tanks? It is necessary to check and inspect the oil tank regularly in the process of use, and do a good job in the maintenance and cleaning of the oil tank. The oil tank should be inspected every 6 years. With the increase of service life, the inspection interval should be shortened. Daily maintenance and cleaning of the API 650 cylindrical tanks can prolong the service life of the oil tank. The maintenance of the API 650 cylindrical tanks mainly includes the anti-corrosion inspection of the oil tank, the maintenance of the accessories, and the cleaning of the sediment in the tank.
