G650 Vacuum Tube Testing Guns
Tube Sheet Joint Testing
__________________________________________________________________________________________
G-650 Tube Sheet joint Testing quickly tests expanded tube-to-tube sheet joints for leakage. Ideal for heat exchanger manufacturers or companies performing re-tubing operations.
Description
Tube to tube sheet leak testing
The G-650 Gun seals the tube ID and along the tube sheet face, then evacuates the tube end at the joint. A loss of vacuum indicates a leaky tube joint. The G-650 Gun operates on standard plant air supplies from 40 to 125 psi (2.7-8.6 bar). A highly efficient venturi creates 21-24 in-Hg (707 to 808 m Bar) vacuum on an inlet air supply of 100 psi (6.8 Bar) and 10 SCFM. Interchangeable Manifolds, and Seal and Washer Sets allow the G-650 to test tube-to-tube sheet joints on 3/8″ OD to 1-1/4″ (9.53 mm to 31.75 mm) OD tubes sizes from 0.280″ to 1.230″ (7.11 mm to 31.24 mm) I.D. The larger G-650A Tube Sheet joint Testing gun will accommodate 1-1/2″ to as large as 2-1/2″ tube sizes. The G-650 Guns are not suitable for testing excessively belled / flared tube ends, or tubes with welded tube-to-tubesheet joints. Specify the following information when ordering:- Tube OD and wall thickness
- Number of tubes to be tested
- Tube pitch and spacing (if known)
- Length or depth of any channel head present
