SUCTION AND DISCHARGE TUBE
BRAZING
Compliant Scroll compressors have copper plated steel
suction and discharge tubes. These tubes are far more
rugged and less prone to leaks than copper tubes used on
other compressors. Due to different thermal properties
of steel and copper, brazing procedures may have to be
changed from those commonly used.
•
To disconnect: heat joint Areas 2 and 3 slowly and
uniformly until braze material softens and the tube
can be pulled out of suction fitting. (See Figure 9.)
•
To connect:
– Recommended brazing materials: silfos with
minimum 5% silver or silver braze material with
flux.
– Reinsert tube into fitting.
– Heat tube uniformly in Area 1 moving slowly to
Area 2. When joint reaches brazing
temperature, apply brazing material. (See
Figure 9)
– Heat joint uniformly around the circumference
to flow braze material completely around the
joint.
– Slowly move torch into Area 3 to draw braze
material into joint. (See Figure 9.)
– Do not overheat joint.
