3003 aluminum plate API 650 aboveground welded storage tanks

All welded seams in the API 650 aboveground welded storage tanks bottom, and complete penetration and complete fusion sidewall-to-bottom welds, shall be inspected by means of a vacuum box test as described in Q.8.2.1. Sidewall-to-bottom welds not having complete penetration and complete fusion shall be inspected by means of either a vacuum box test of the inside weld as described in API 620 specification Q.8.2.1, or where approved by the Purchaser, a direct pressure solution film test as described in Q.8.2.2.

The floating roof is the top cover floating on the liquid level, so the sealing performance of API 650 aboveground welded storage tanks API 650 oil storage tank is very important. The floating plate mainly adopts elastic packing, and at the same time, it is compressed with the wall of API 650 oil storage tank with pressure strip around, and fixed with the floating plate with bolts. After the API 650 aboveground welded storage tanks floating plate is lowered to a certain position of about 1.8m, a prop will support the floating plate to keep it in position.

How to effectively increase the service life of API 650 aboveground welded storage 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 aboveground welded storage tanks can prolong the service life of the oil tank. The maintenance of the API 650 aboveground welded storage 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.
