EXPANSION JOINTS     ... An expansion joint is a specially engineered product inserted in a rigid piping system to achieve one or more of the following: - Absorb movement - Relieve system strain due to thermal change, load stress, pumping surges, wear or settling - Reduce mechanical noise - Compensate for misalignment - Eliminate electrolysis between dissimilar metals At Garlock, the range of our engineering emphasis extends from the selection of the fabric used for reinforcement to the choice of materials used in actual expansion joint construction. Rigid laboratory and field tests of Garlock expansion joints are what back up our assurances of long life and reliable service. An important word on safety: all Garlock expansion joints carry safety ratings exceeding product specifications in such areas as temperature and pressure. Garlock nonmetallic expansion joints and flexible couplings are ideally suited for hundreds of applications in a wide range of industries, including: - Power generating stations - Pulp and paper - Chemical and industrial process piping - Waste water and sewage disposal - Marine applications - Heating, ventilating and air conditioning             PTFE Concentric Spool -Type Flexible Coupling   GARFLEX® 8100 - Yellow Band, Nitrile Tube Nylon Reinforced   THE MASTERFLEX - New Economical and Versatile Elastomeric Expansion Joint   Style 204 EVS – Extreme Vacuum Service
