Higher temperature. Alkali caustic cracking has a wide temperature range, the alkali stress corrosion of carbon steel generally occurs in 50~80 or above, and about 60 is the lowest critical temperature, which is related to the concentration of alkali.
For carbon steel piping, a corrosion allowance of 3 mm shall be used, unless higher corrosion allowances are required. Recommendation For submarine pipeline systems a total corrosion allowance of 10 mm is recommended as a general upper limit for use of carbon steel.
