General Information
Covering of
Refrigerant Pipes
Covering is an extremely important operation as it prevents water, dirt or dust from getting
inside the pipes.
Moisture inside the pipes was a constant source of trouble in the past. The
utmost care is required to nip this problem in the bud.
The end of each pieces of pipe must be covered.
“Pinching” is the most effective method but
“taping” is an simple alternative which may be used according to the work area and term of work.
1. Pinching method
The end of the copper pipe is squeezed together and the gap brazed.
2. Taping method
The end of the copper pipe is covered with PVC tape (vinyl tape).
<Taping method>
Particular care should be taken during the following operations:
When passing copper pipe through a penetration hole (Dirt easily gets into the pipe).
When copper pipe is located outside (Rainwater gets in)
(Special care is needed when the pipes are standing vertically outside)
