MDC high pressure Controlled Flexing, High Corrugation expansion joints combine a corrugated pressure carrier with closely mated neck rings and reinforcing or control rings. This constructio permits their use with higher pressures (150 psig and 300 psig) in applications where large amounts of axial movement are required. Widely used in such applications as process and steam lines, pump suction and discharge lines, turbine-to-condenser connections and fuel supply lines. Available with either Vanstone (floating) flanges (Model CSF) or with weld ends (Model CSW).
