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.
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.
