    Nuclear Steam Generator (SG) service reliability and. longevity have been seriously affected worldwide by. corrosion at the tube-to-tubesheet joint expansion. Current SG designs for new facilities and replacement. projects enhance corrosion resistance through the use. of advanced tubing materials

    transfer rate. Additionally, tubing systems can be installed in about half the time required for a piping system when long length coils are used due to the elimination of the many welded joints required to make up a rigid carbon steel pipe tracer for a complex process piping system. A semi-rigid
  • Designing with inflatable seals
    a circular seal from long straight sections. But joint sections may not rise as high when inflated compared to the rest of the seal. For enclosures and equipment that rely on flexible seals, inflatable bladder-type seals might be a better choice than compression seals. They are more forgiving
