G-150 Tube Testing Guns are designed to pneumatically test individual tubes in a heat exchanger for pinhole leaks.
G-150 Tube Testing Gun Set includes one G-150 Air Injection Gun and one G-150 Tube Plugging Gun. 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 (27-8.6 bar). Interchangeable Seal and Washer Sets allow the G-150's to test tube sizes from .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. 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.
