BAFFLES
Are usually not necessary with elastomeric expansion joints due
to the tube resistance to most abrasive particular matter. However, baffles must be used
with fabric composite joints to protect the inner surface form particulates in the gas
stream. UNAFLEX® can supply baffles fabricated from carbon steel, stainless steel, or other
materials as required. |
