3.4.2 Preparing and cutting copper refrigeration pipes
Preparation
Clean the area where the copper refrigeration pipe preparation work is to be carried out. It must particularly be free of
waste, soil, wood or metal shavings and, in general, any substance that could enter the ends of the pipe during handling.
The copper pipe must be clean and have no remains of adhesive, cement, dust or other substances adhered to it.
Where the copper pipe is supplied in rolls, fit a cap on the end and unwind it while it is resting on the ground so that the
turning movement of the roll as it is unwound forms a straight pipe.
?
N O T E
• The rolls of copper refrigeration pipe are normally supplied with caps on their ends.
• Where the roll of pipe does not come supplied with caps, check that the inside of the pipe is clean. If it is not, use a new roll of pipe.
• It is also possible to cover the end of the pipe temporarily using high quality adhesive tape.
• Do not wind and unwind the pipe continuously, as the properties of the copper for refrigeration pipes are altered, making it more rigid
and brittle.
Cutting
Define the necessary length of pipe and add a few more centimetres to give yourself enough margin in case the cut has
to be repeated.
Cut the pipe using a pipe cutter.
!
C A U T I O N
Ensure the pipe cutter rollers remain perfectly seated on the copper pipe.
