Vacuum Joint Testing provides a fast and effective method for pneumatically testing heat exchanger tubes and tube to tubesheet joints for leaks.

 

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

 

The G-650 Gun operates on standard plant air supplies from 40 to 125 PSI. A highly efficient venturi creates 21-24 in-Hg vacuum on an inlet air supply of 100 PSI (6.8Bar) and 10 SCFM. Interchangeable Manifolds, and Seal and Washer Sets allow the G-650 to test tube-to-tubesheet joints on 3/8" OD to 1-1/4" (9.52mm 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.

 

 

G-150 Tube Testing Guns are designed to pneumatically test individual tubes in a heat exchanger for pinhole leaks. Either the entire tube bundle or an isolated number of tubes in the bundle can be tested using standard plant air supplies from 40 to 125 PSI. Interchangeable Seal and Washer Sets allow the G-150's to test tube sizes from 0.280" to 1.230" (7.11mm to 31.24mm) I.D. The larger G-150A Testing Guns will operate in tube sizes to 2.500" (63.5mm) I.D. G-150 Tube Testing Gun Set includes one G-150 Air Injection Gun and one G-150 Tube Plugging Gun. The G-150 Air Injection Gun and G-150 Plugging Guns weigh less than 2.1 lbs. (1 kg) apiece. The G-150A's weigh less than 2.4 lbs. each.

 

The G-150 Tube Testing Guns are easy to operate. Simply insert both the Air Injection Gun and Plugging Gun into the tube end, press an air control valve button, air expands the seals on both guns and pressurizes the tube. When the pressure in the tubes stabilizes release the air control valve. Any reduction of pressure indicated on the large pressure gauge will reveal even the smallest tube leak. An optional digital gage increases the guns ability to detect even the smallest pinhole leaks.
