In some instances, the pipes are required to go through a
by coring method) to accommodate all the pipes going
through. Suitable brackets may then be fabricated to hold the
pipes together.
6.11 Pipe Bends
Copper pipes MUST NOT be bent with bare hands. This will cause the pipe to dent or collapse at the
bent area. Use the proper pipe bending tool and the correct tool size corresponding to the required
pipe diameter
Figure 6.12: Pipe bender
Pipes up to ¾” can be bent by using the pipe bending tool. Generally, larger pipes are not bent but
rather copper elbows are used instead. The elbows are brazed onto straight lengths of pipe.
Figure 6.13 : Copper Elbow
An application example will be making an oil trap. The pipe bending tool is used to bend the two
U-shape of the trap. For the larger pipe size, braze together 4 elbows to form the trap.
Tubing Connections
Be certain both refrigerant service valve at the condensing unit are closed (turned fully
clockwise).
All lines should be assembled with type "L" refrigerant tubing and not with copper water pipe.
They should be brazed with the following alloy:
FOR SWEAT-TYPE TUBING CONNECTIONS:
Always keep chips, steel wool, dirt etc. Out of the inside of tubing when cleaning.Assemble
Remove cap and schrader core from service port to protect seals form heat damage.
Wrap service valve with a wet rag before applying heat. Braze the tubing between
outdoor unit and indoor coil. Flow dry nitrogen into service port and through the tubing
while brazing.
