Hello All!!!

How do you interpret this statement from ASME B31.3 321.1.1

"The layout and design of piping and its supporting elements shall be directed toward preventing the following:

(f) excessive interference with thermal expansion and
contraction in piping which is otherwise adequately
flexible."

My interpretation is to avoid interference or clashing with adjacent elements due to thermal expansion or contraction. Please correct my understanding.

Thanks & Warm Regards,
