Balanced rotating welded Alloy 718 bellows seal for high temperature petrochemical services. This seal complies fully with all requirements of API 682 type C. The use of Alloy 718 material and a low stress bellows design provides improved corrosion resistance. The special stationary face shrinkfit design minimizes face distortion and allows low leakage and low wear under a wide range of conditions. The rotating bellows is self-cleaning, which reduces the possibility of solids entering the bellows convolutions.
