Stress developed due to sudden flow of steam at 500 F into tube at ambient temperature

[strainstress]

Does ASME discusses about the stress due to thermal shock of introducing fluid at high temperature to a pipe at ambient conditions ? If yes, can you refer the appropriate section.

PS: I have posted similar question on pipeline forum. I apologize for double posting in advance.

Not for Section I or B31.1 application.

Concur -- ASME assumes that operators are competent and careful. With boiler operators, it is a darwinean process; the 'thunder-thumbs' on the control board are sent to shovel slag [or sent home]. The banging and clanging of a harsh startup cannot be hidden.
