RPV Stud Caps

Preferred Engineering’s RPV Stud Caps are designed to isolate the Elongation Rods and RPV stud cores. The Stud Caps are machined from billet aluminum and use a hardcoat anodize protective finish. A passively retained O-Ring provide sealing thus allowing Elongation Rods to remain inside the RPV Stud eliminating ‘soak’ times which are required to acclimate the Elongation Rods to temperature.

Benefits

  • Recess for elongation rod clearance eliminates the need to remove them and eliminates ‘soak’ time prior to tensioning
  • Passively retained O-Ring, no glue or hardware required.
  • Square drive for fast and accurate installation with torque wrench.
