Thermospan Expansion Joints
Thermospan fabric expansion joints are
custom-made for ducting applications where high
temperature, moderate pressure, high abrasion and
adverse chemical conditions apply. All unusual
situations can be referred to Thermolag for
recommendations. Our design engineers are
available to give assistance in the field.
APPLICATIONS Thermospan expansion joints excel in
power generating plants in dry gas systems. They
are also recommended for high-temperature exhaust
gas systems in process plants, paper mills, steel
mills, foundries, cement mills and in refinery
and chemical plant applications that use
scrubbers and precipitators. These compensators
are suitable for vibration isolation of forced
draft and induced draft fans. BAFFLING Internal
baffles may be required to protect the inner ply
from abrasive effects of particles. Thermolag
will supply these plates.
SERVICE Thermospan expansion joints in the 150C
900 C range are used primarily on the cool
side of the flue system or process lines where
gas temperatures climb above the condensation dew
point. Thermospan expansion joints are designed
to match operating conditions for both continuous
service - and excursion temperatures.
EXTERNAL INSULATION Thermospan expansion joints
contain their own internal insulation, therefore
no external insulation is required. If external
insulation is applied, it will severely limit the
operating exclusion temperature capabilities.
