 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.
