request-a-quote_red-rectangle.png  request-a-demo_red-rectangle.png

Provides a fast and effective way to seal off and evacuate individual heat exchanger tubes to test the tube for leakage.

  • Pneumatically Test Heat Exchanger Tubes
  • Test Tube-to-Tubesheet Joints for Leaks

G-250 Vacuum Tube Testing Tools are designed to quickly seal off and evacuate individual heat exchanger and vacuum tubes to test the tube for leakage. 

Requirements

  • Plant air supply between 40 and 125 psi (2.7 to 8.6Bar)
  • Air supply flow rate greater than 5 SCFM (2.36lps) 
 

Features & Benefits

  • Supplied with two sizes of interchangeable conical neoprene Seal and Washer Sets and a compact toolbox
  • Test heat exchanger tubes ranging from 0.28" to 1.45" (7.1mm to 36.8mm) ID
  • Durable - machined from high strength aluminum alloy
  • Light Weight - each set weighs less than 2.5 lbs (1.1kg), reducing fatigue associated with heavier testing equipment

Additional Information


Specify the following information when ordering:

  • Tube OD and wall thickness
  • Tube length, tubesheet face-to-face dimension
  • Number of tubes to be tested
  • Length or depth of any channel head or header box present

Operating the G-250 Vacuum Tube Testing Tool

  1. Connect the standard plant air supply to the active vacuum gun and insert the conical seal into the end of the tube to be tested. 
  2. Insert the passive plugging tool into the opposite end of the tube. 
  3. Depress the air control valve, air flows through the vacuum generator and evacuates the tube.
  4. Release the air control valve and any loss of vacuum indicated on the vacuum gauge identifies a leaking tube.

An optional digital vacuum gauge increases the operator’s ability to detect even the smallest pinhole leaks.
