G-650 Vacuum Joint Testing Gun PDF

G-650 Vacuum Joint Testing Gun quickly test expanded tube-to-tubesheet joints for leakage.

Ideal for heat exchanger manufacturers or companies performing retubing operations.

The G-650 Gun seals the tube ID and along the tubesheet face, then evacuates the tube end at the joint.

A loss of vacuum indicates a leaky tube joint.

Operational Benefits

  • Manufacturers or Retubing: Ideal for heat exchanger manufacturers or companies performing retubing operations.
  • Easy to detect leaks: Seals the tube ID and along the tubesheet face, then evacuates the tube end at the joint. A loss of vacuum indicates a leaky tube joint.
  • Uses standard air supplies: Operates on standard plant air supplies from 40 to 125 psi (2.8-8.6 bar). A highly efficient venturi creates 21-24 in-Hg (707 to 808 mBar) vacuum on an inlet air supply of 100 psi (6.8Bar) and 10 SCFM.
  • Interchangeable Manifolds, Seal and Washer Sets: This allow the G-650 to test tube-to-tubesheet joints on 3/8″ OD to 1-1/4″ (9.53mm to 31.75mm) OD tubes sizes from 0.280″ to 1.230″ (7.11mm to 31.24mm) I.D. The larger G-650A Joint Testing Gun will accommodate 1-1/2″ to as large as 2-1/2″ tube sizes.
