ASTM A662 plates API 650 stainless steel storage tanks

Generally, external environment corrosion should be considered before design and construction of API 650 stainless 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.

Under the same sealing effect, the internal floating roof tank of API 650 oil storage tank can further reduce the evaporation loss compared with the API 650 stainless steel storage tanks External floating roof tank. This is due to the shielding of the fixed roof and the gas layer between the fixed roof and the internal floating plate, which has more significant heat insulation effect than the double disc floating roof of the API 650 stainless steel storage tanks external floating roof tank. =====
API 650 tank has the advantages of less load on the floating plate, simple and light structure, and can save the central drainage pipe and rotating floating ladder on the API 650 stainless steel storage tanks floating plate. The materials for easy construction and maintenance and sealing parts can avoid aging due to sunlight.

With the development of multimodal transport in the international shipping market and the increase of the complexity of the integrated transport chain, modern ports, as the intersection of the three transportation modes of sea, land and air, are developing from traditional transfer and product distribution functions to all-round value-added services, becoming the central link connecting the world's production, exchange, distribution and consumption, and supporting the world economy and international trade An important part of the developed international circulation system.
