[Help] How to determine the corrosion margin C2 for steel plates?
Thread Content
It says 150, but it’s not specific; I still don’t understand after reading it. I don’t know where certain materials are kept and how to obtain them when they’re needed Thank you
There is a book written by Wang Fei titled \"Methods and Key Points of Chemical Engineering Equipment\", which provides information on this topic in the forum
Could you give me a specific address? I can’t find it. I’m a beginner:P
C2=Nf×dC2, where Nf is the design life, typically ranging from 10 to 15 years； dC2 represents the corrosion rate. Selection of corrosion allowance: For container shells and heads, the corrosion allowance shall be: a. For containers made of carbon steel or low-alloy steel that are exposed to compressed air, water vapor, and water, the corrosion allowance must not be less than 1.0 mm ； b. Other than a: the corrosion rate is less than 0.05, so the corrosion margin is set to 0 ； The corrosion rate is between 0.05 and 0.13, with a corrosion margin of 1 or more ； The corrosion rate is between 0.13 and 0.25, with a corrosion margin of 2 or more ； For those with a corrosion rate greater than 0.25, the corrosion margin is greater than or equal to 3. The maximum corrosion margin shall not exceed 6 mm; otherwise, anti-corrosion measures must be taken.
For carbon steel, low-carbon steel, and low-temperature carbon steel, the values generally range from 1.5, 2, to 3, depending on the corrosion rate of the medium. Stainless steel is basically 0
