As far as practicable, piping should not pass through accommodation areas. Where it
is not practicable to insist the piping not pass through accommodations areas, the pipelines
may pass through accommodations provided that they are of substantial thickness and that
their tightness is verified with a pressure test, after installation, at a pressure head not less than 50 bar (725 psi). In addition, pipes passing through accommodation areas should be joined only by welding and should not be fitted with drains or other openings within the spaces. |
