35ft diameter API standard 650 welded steel storage tanks

API 620 crude oil tank piping materials made according to ASTM A333 and A350 may be used at API standard 650 welded steel storage tanks design metal temperatures no lower than the impact test temperature required by the ASTM specification for the applicable material grade without additional impact tests. For temperatures below those allowed by the ASTM specification, the following paragraph shall apply.

Under the same sealing effect, the internal API standard 650 welded steel storage tanks floating roof API 650 tank can further reduce the evaporation loss compared with the external floating roof API 650 tank. This is due to the shielding of the fixed roof and the gas phase layer between the fixed roof and the inner floating plate, which has more significant heat insulation effect than the double disc floating roof of the API standard 650 welded steel storage tanks external floating roof tank.

ANDRITZ GROUP is the world's leading industrial group, with 29500 employees and more than 280 branches in more than 40 countries. We have cooperated with their Mexico company for many years about S355J2+N steel plates and cutting sectors. The S355J2+N steel plates API standard 650 welded steel storage tanks need to cut according to the drawing by standard tolerance, UT, MT and dimension request. The final application of the S355J2+N steel plates and cutting sectors are for assembling hydraulic machine.

Generally, external environment corrosion should be considered before design and construction of API standard 650 welded steel storage tanks and so on storage tanks. The corrosion on the outer surface of storage tank is often worse than that on the inner surface. Especially in the chemical industry area, there are often acid fog, alkali or salt dust in the atmosphere. These impurities form an active corrosive medium with dew or steam and oxygen in the atmosphere. The corrosion of the external environment of the storage tank shortens the maintenance period of the storage tank, even causes the storage tank to be scrapped in advance, which affects the normal operation of the storage and transportation.

We should focus on the main problems to be solved and pay attention to efficiency. After receiving the user's quality objection report data, the possible causes, responsible units, compensation amount, etc. of the problem shall be judged based on experience. To have a clear service plan, to be clear about what your main problem is, what technical support is needed, these should be prepared.
