About thermal expansion

(OP)
API Standard 521 (ISO 23261) states that the required relieving rate is difficult to calculate and that a portable 3/4" x 1" valve is very commonly installed to provide protection.
The standard does give some cautions with regards to large diameter liquid pipelines where the distance between isolation devices may be long or where the application deals with liquid filled heat exchangers and
vessels.
My question is the long distance is exactly how many meters? and larger diameter means how many meters the diameter should be?

Set up a spreadsheet and do some calculations to see what you are likely dealing with.
