BXHH Metal Bellows Seal

The BXHH is a balanced rotating welded Alloy 718 bellows seal designed for high-temperature petrochemical services. It fully complies with all requirements of API 682 type C. The use of Alloy 718 material, along with a low-stress bellows design, enhances corrosion resistance. The seal features a special stationary face shrink-fit design that minimizes face distortion, allowing for low leakage and wear under a wide range of conditions. Additionally, the rotating bellows is self-cleaning, reducing the risk of solids entering the bellows convolutions.
