Dear All,

I am working for flowlines per ASME B31.8 Ch.VIII. While checking material database for API 5L X60, I have noticed that thermal expansion coefficient data for low temperature are not available for temperature lower than 32 deg F. As codes are not restricting the use of the material at the lower temperature range, I think CAESAR II database shall be updated.

Currently I am assuming the expansion coefficient from 32 deg F to -100 deg F as same value as 70 deg F. It would be more conservative.

Please let me know whether it is intended or omitted by COADE.
