Electric Stud Drive Tools (ESDT) - Biach RPV Stud Tools

Description

Model: Electric Stud Drive Tools   |   Series:   |  Product Line: Nuclear Tools

The Biach Electric Stud Drive Tool (ESDT) is used for safe removal and re-installation of reactor pressure vessel (RVP) studs in minutes.

The ESDT offers smooth, quiet operation in a noisy environment and relieves workers from the dangerous role of absorbing breakaway torque during stud rotation. Its electronic control provides an exact stud positioning during thread-in to assure consistent stud projections around the vessel and to prevent binding due to hitting the bottom of the stud hole.

Stud weight compensation is provided via a built in air compressor or by connection to plant air supply.

Enerpac's nuclear engineers converted and upgraded the earlier pneumatically driven Stud Drive Tool (SDT) to electric power.

Features:
  • Load compensation provides zero stud weight effect during operation
  • Quick connect stud gripper
  • Electric drive provides smooth and quiet operation
  • Height of the stud during threading/unthreading is monitored and displayed on the digital read out indicator
Benefits:
  • Safely threads studs in and out of the nuclear reactor pressure vessel (RPV) in minutes
  • Easy to handle, position and operate by one person
  • The operator doesn’t experience any harmful torque during stud rotation
  • Pneumatic weight compensation keeps the stud ‘weightless’ during rotation which prevents any stud, stud hole or thread damage.
