Fast & Effective|Pneumatically Testing|Light Weight
Provides a Fast and Effective Method for Pneumatically Testing Heat Exchanger Tubes and Tube-to-Tubesheet Joints for Leaks, G-250 Vacuum Tube Testing Guns are designed to quickly seal off and evacuate individual heat exchanger tubes to test the tube for leakage.
Operation is easy. Connect standard plant air supply to the active vacuum gun and insert the conical seal into the end of the tube to be tested.
Insert the passive plugging tool into the opposite end of the tube.
Depress the air control valve, air flows through the vacuum generator and evacuates the tube.
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 operators' ability to detect even the smallest pinhole leaks.
Two standard seal and washer sets: allows testing from 0.28 to 1.45 (7.1 – 36.8 mm)., Optional seals available to allow testing to 2.5
Gun and T-handle weigh less than 2.1 lbs (1 kg)
Standard Seal Material
Quality assurance system certified to ISO-9001, Quality assurance system that meets requirements of ANSI N45.2, 10CFR50 Appendix B, 10CFR21
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
