Internal components of api 620 tank inspection

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 620 tank inspection 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.

The water dissolved in the oil will be separated out from the oil stored in the api 620 tank inspection for a long time, and the acidic water layer will appear at the bottom of the api 620 tank inspection for a long time, which will accelerate the corrosion of the api 620 tank inspection and cause the wall thinning and even leakage. With the increase of service life, the api 620 tank inspection must be inspected and cleaned regularly to check the hidden danger.

Company management philosophy: integrity-based, service-oriented, excellence, affinity symbiosis. Based on quality, continuously create maximum value for customers. Always have a grateful heart, thank the society, thank family and friends for their support and help to the development of the company, thank customers for their trust, thank colleagues for their cooperation, and thank competitors for their supervision.

The company formulates clear service process and service standard. To do a good job in after-sales service, first of all, clear service process and service standards should be formulated to let employees know which procedures to perform and which service standards to abide by.
