Tube Leak Detection And Tube Plugging Services

Fairtex Group provides Tube Leak Testing with Helium Helium Leak Detection, Tube Leak Detection Helium tube leak testing with a mass spectrometer is the most accurate and sensitive method for finding tube leaks. Using this method, Fairtex Group's personnel can locate leaks as small as 2x10^-9 atm cc/sec helium. The process involves covering sections of tubes with plenums, which directs the helium into the tubes. If there is a leak within a section, the technician uses smaller and smaller plenums until the exact tube is identified and marked.

Foam Tube Leak Testing

The foam tube testing method uses foaming liquid and a spraying device to coat both sides of a condenser or heat exchanger tube sheet. The foam is spread across the face of the tube sheet to cover each tube. Leaking tubes are identified when the foam is drawn from the tube sheet and down the length of the tube. This method is best for quickly finding large leaks and is the fastest available method when the condenser system is online. Another benefit of this method is that technicians can more easily distinguish between tube sheet leaks and tube leaks, whereas with other systems such as mass spectrometry, it can be difficult. One drawback to this method is that it cannot detect extremely small leaks that mass spectrometry can find. However, if you have significant tube leaks and are in a hurry, this is the method to choose.

Pressure Testing Tube Leak Detection

Pressure Test Tube pressure testing is performed by two operators using special air guns. The guns are inserted at each end of a tube, and the triggers are pulled. Pulling the trigger creates a seal between the gun’s nozzle and the tube and allows air to flow into the tube. The tube fills with air, and a gauge is monitored to observe the pressure. If the pressure remains constant after releasing the trigger, the tube is not leaking. However, if the pressure decreases after releasing the trigger, there is a leak in the tube.

Tube Plugging After locating the leaks

Fairtex Group Tube Cleaning personnel can also plug these leaks. We offer numerous types of plug designs depending on the types of tubes or customer preference (Tube Plugs). Because we manufacture the plugs, we can offer customers special discounts on our plugging services that other providers cannot.

Preventing leaks and other issues with your heat exchangers and condensers is one of the many reasons to keep your tubes clean and as free of blockage as possible. Leaking tubes and problems of all kinds can be mitigated by consistent and regular tube cleaning.
