BUNCH AND PANCAKE COILS
Pancake coils
are typically used in the installation of air conditioning and
refrigerator systems. They are also used in OEM end uses.
Pancake coils are provided in a flat coil which are two layers
thick. Bunch coils are similar to pancake coils, but all of
the individual loops have the same diameter much like the coil
of wire.
PANCAKE AND BUNCH COILS Produced in
the following outside diameter size ranges.
MIN. DIAMETER -- 3/16
(4.76 mm)
MAX. DIAMETER Ύ (19.05
mm)
Lengths: Standard available
length is 50 feet. We can provide lengths ranging from 2
meters up to 100 meters as per clients' requirement in coil
form.
Packaging: Pancake coils are
available in individual polythene bag, packed and stacked in
corrugated box.

Testing: All
coils are provided with no detectable defects and are supplied
in accordance with ASTM specification.
Cleanliness:
All annealed coils meet or exceed the cleanliness levels
specified in ASTM B-280. Coils are capped with plastic end
caps when so specified by the customer.
Tolerances:
Tube in pancake or bunch coils are produced to the applicable
specifications of ASTM B-68, B-280, or B-88.
Tempers:
Bunch or annealed coils are provided in following tempers: dead
soft, soft annealed and
light annealed.
TEMPERS
The following are available
depending on the product form. Consult specific data listed
for each product to determine which tempers are available.
-
Dead Soft: .070 mm grain and above this is a large
grained product and used where the product is cold worked
repeatedly. This temper work hardens at a much at a slower
rate but is not suitable for extreme forming.
-
Soft Anneal (060): .040 -- .060 mm grain this temper
is suitable for general purpose bending and forming which
is not as extreme as that requiring light annealed temper.
Soft anneal temper works hardens at a slower rate than
light anneal.
-
Light Anneal (050): .015 -- .040 mm grain preferred
for tight bends and extreme forming application. This is
an annealed temper with a fine grain size to prevent orange
peel and fracturing when forming.
