What is the corrosion allowance for liquefied petroleum gas?

What is the corrosion allowance for liquefied petroleum gas? I help with design work; I’m not from a chemical engineering background, so there are no design manuals available.
The corrosion allowance for LPG pipelines is 1.6 mm, in accordance with \"Design and Management of Gas Pipelines\" http://bbs.hcbbs.com/viewthread.php?tid=219719&page=1&extra=page%3D1#pid958562
Could it be 0.16? I’ve seen that LGP used for storage over 20 years also has a thickness of 5 mm, with a pressure of 0.2
The safety factor is determined primarily based on the application, operating pressure, and surrounding environment
For ordinary carbon steel pipelines, with a design life of 15 years, a corrosion allowance of 1.5 is adopted; the maximum corrosion allowance is 6. Once this value is exceeded, it is necessary to use materials with better corrosion resistance. For liquefied gas, carbon steel is likely to be used, so a corrosion allowance of 1.5 should suffice
