PRODUCT FEATURES
INSULATION PROPERTY.
Imperial Armstrong is made of electrically
non-conductive material. It eliminates
the
possibility of electrolytic corrosion, grounding
and short circuit.
FRICTION-REDUCED BORE.
Imperial Armstrong has a smooth inner surface
that enables wire pulling to be easy and
fast, and
prevent damages to the wire insulation.
DIELECTRIC STRENGTH. Imperial
Armstrong can withstand a 2000-volt sine-wave
voltage having a frequency of 60 Hertz for
15 minutes between two electrodes applied
to the pipes.
NON-CORROSIVE. Imperial
Armstrong will never rust and is highly resistant
to a wide range of chemicals.
NON-FLAMMABLE. Imperial
Armstrong is self-extinguishable thus it
is
most ideal in places where fire prevention
is important.
LIGHTWEIGHT AND ECONOMICAL.
Imperial Armstrong is 1/5 the weight of its
steel conterpart thus pipe installation is
much faster.
