FLARING THE PIPE END 

Lt_ WARNING 

Incomplete flaring may result  refrigerant gas leakage. 

1) Cut the pipe end with a pipe cutter. 

2) Remove burrs with the cut surface facing downward, so that the fillings 

do not enter the pipe. 

3)  Put the flare nut on the pipe. 
4) Flare the pipe. 
5) Check that the flaring has  been done correctly.

1) To prevent gas leakage, apply refrigeration oil to the inner surface of the flare. 

2) Align the centres of both flares and tighten the flare nuts 3 or 4 turns by hand.  Then tighten them fully with the torque 

wrenches. 

• Use torque wrenches when tightening the flare nuts to prevent damage to the flare nuts and escaping gas.

Cautions on Pipe Handling 

1)  Protect the open end of the pipe  against dust and moisture. 

2) All pipe bends should be as gentle as possible. Use a pipe bender for 

bending. 

Selection of Copper and Heat Insulation materials 

When using commercial copper pipes and fittings, observe the following: 

1)  Insulation material : Polyethylene foam or equivalent. 

Heat transfer rate - Co-efficient :  0.041  to 0.052W/m'K 

( 0.035 to 0.045kcal/m
