15ft diameter API 650 cylindrical welded storage tanks

The company has a mature technical team whose reponsibility is to design the drawing, choose suitable material and evaluate the whole production processaccording to customers’ requirement. The company is led by talents and technology, and comprehensively promotes its six business segments like steel material supply, precision steel casting, environmental protection equipment, household appliance, API 650 cylindrical welded storage tanks steel structures and oil tank projects. Seeking new developments in new technology and business areas, and fostering a large number of industry-leading, international-level projects.

The longer the service life of the API 650 cylindrical welded storage tanks, the lower the reliability and the prone to failure. Doing a good job in the maintenance of the metal oil tank can ensure the normal use of the oil tank, reduce the wear of the API 650 cylindrical welded storage tanks body and accessories, and extend the service life of the oil tank. The maintenance of metal oil tanks is mainly to do a good job in the anti-corrosion of the oil tank, the cleaning of the deposits in the API 650 cylindrical welded storage tanks and the overhaul of its accessories. Regularly inspect and maintain the accessories of the oil tank: valves, oil measuring holes, breathing valves, flame arresters, ladders, foam fire extinguishing generators, etc., and make records. If any damage is found, repair them in time.

A cylindrical nozzle with a 12-in. inside diameter is located in solid plate in the sidewall of a cylindrical storage tank 60 ft in diameter so that its axis lies in a horizontal plane and forms an angle of 55° with a perpendicular to the sidewall at the point of intersection, as shown in Figure F-7. The thickness of the API 650 cylindrical welded storage tanks sidewall plate, tw, in this area is 5/8 in., and no corrosion allowance is required. The total internal pressure, Pl + Pg, at the center of the opening is 26.1 lbf/in.2 gauge.
