3 - Insulating with Arma-Chek D >> Using Pre-Covered Sheets
CONCENTRIC REDUCER - EQUAL
1. Determine the measurements d1 and d2 (pipe
di 2 x insulation thickness) of the small and
large pipe and the height h.
2. Determine the circumference by placing a strip of
factorycoated Arma-Chek D sheet material in the
thickness to be used loosely round the larger dia-
meter pipe.
Do not stretch the strip!
3. Transfer the measurements determined onto the
surface of the factory-coated Arma-Chek as shown in
the picture. Minimize material waste by drawing the
half elevation on the edge of the Arma-Chek sheet.
4. Completed Arma-Chek pipe reducer made of factory
coated Arma-Chek Dsheet material with a straight
fi nish.
ECCENTRIC REDUCER - FLAT BACK
1. Determine the measurements d1 and d2 (pipe dia-
meter of the bare small and large pipe), the height h
and the true length b. Calculate the measurements
d1 and d2 (diameter of the respective pipe + 2 x insu-
lation thickness).
2. Determine the circumference by placing a strip of
factory coated Arma-Chek sheet material in the thick-
ness to be used loosely round the larger diameter
pipe.
Do not stretch the strip!
3. Transfer the measurements determined, onto the
surface of the factory-coated Arma-Chek, as shown
in the picture.
4. Modify the pattern in fi g. 3 to the appropriate pattern
for an eccentric reducer as shown here.
