Expansion joints in a pipe rack
Expansion joints in a pipe rack
(OP)
I am designing an external pipe rack. If I have two braced bays in the length how far apart can they be before I need to put an expansion joint between them to relieve stresses from thermal expansion? Say there is a 50 degree temperature change from installed condition.

At 120F about .078'(about 1'') per 100' feet of length.

1. That's 50 deg C, about 90 deg F
2. Due to access the braced bays can't be moved closer together.
3. Assume there are an indeterminate number of unbraced bays between the ends.
So how far can I go before thermal expansion becomes a design issue?

anyhow put your brace frame every 5 bent frames if possible.
also your brace bay is not usual for piperacks.
try inverted chevron from ground to top

How many intermediate bays can you have without an expansion joint?
RE: Expansion joints in a pipe rack
maximum 150 ft. but usually we use 100 ft.
for every 100 ft you need 1 brace bay just like my drawing and is usually located at the center if possible but not necessarily.
