Construction of pipelines passing through accommodation
Pipelines may pass through accommodation spaces provided
they are of substantial thickness and that their tightness is verified
with a pressure test, after their installation, at a pressure head
not less than 5 N/mm2. In addition, pipelines passing through
accommodation areas should only be joined by welding and should not
be fitted with drains or other openings within such spaces. Pipelines
should not pass through refrigerated spaces.
