Operational steps
Positioning of the
Pipe Holes a) The through holes for the drain piping should be positioned such that the pipes have a
downward gradient. (The gradient must be at least 1/100. The thickness of the insulating
materials must also be taken into consideration.)
b) The diameter of the through holes for the refrigerant piping should include an allowance for the
thickness of the heat insulation materials. (It is a good idea to think of the liquid and gas pipes
as pairs.)
c) Attention should be paid to the construction of the beam themselves since there are sometimes
parts of the beam which cannot be used to accommodate through holes.
Example: Through holes in a reinforced concrete beam
