API standard 650 duplex stainless steel tanks foundation

Large Low-Pressure Tanks Corrosion Allowance
In cases in which the rate of corrosion is closely predictable, additional metal thickness over and above that required for the initial operating conditions shall be provided and shall be at least equal to the expected corrosion loss during the desired life of the tank.
When corrosion effects are indeterminate before the tank is designed (although they are known to be inherent to some degree in the service for which the tank is to be used), and when corrosion is incidental, localized, or variable in rate and extent, the best judgement of the API standard 650 duplex stainless steel tanks designer must be exercised in establishing reasonable maximum excess tank wall thicknesses. For all tanks that come under this classification, a minimum corrosion allowance of 1/16 in. shall be provided.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 standard 650 duplex stainless steel tanks floating plate. The materials for easy construction and maintenance and sealing parts can avoid aging due to sunlight.We participated the National Railway tender of Bangladesh with our local agent together, and won the 1000 tons corten steel sheets order. The corten steel sheets are used to make train carriage. We finished production of the 1000 tons corten steel API standard 650 duplex stainless steel tanks sheets within 40 days, and arranged SGS test for the customer before shipment. The customer gave very high comments to our product and service quality, as well as fast delivery.The elastic filling and sealing of floating roof API standard 650 duplex stainless steel tanks is to fill the elastic and changeable objects in the sealed envelope, and the sealing purpose depends on the compression deformation of the filler. This kind of sealing effect is good, the requirement of the geometry of tank wall is not too high, and the adaptability is strong. However, the elastic filling and sealing has poor wear resistance and is easy to deform and damage in long-term use.Since its establishment, the company has been deeply supported and loved by customers with its unique business philosophy and business model.
