Helium allows for the location of small leaks. Often we can track them down while the process is still in operation. Helium is inert and does not need to be voided from a process before the process is put back into production. A quick phone call today and you can talk to an expert who can help you determine if we can help.
We can provide outside-in testing. In this type of testing, a helium detector is attached to the process to be tested, and a tight vacuum (up to 10^-8 torr)is drawn, helium is applied to the outside of the vessel to be tested. The detector monitors helium that is drawn into the equipment and through the vacuum to the detector. This technique can work for tube and sheet testing, Pressure vessel testing, vacuum process and distillation testing and more. Call today to find out how we might be able to help.
Inside-out testing is also known as pressure testing. Helium is introduced into the process and a leak “sniffer” is used to find places along the system where the helium is escaping.
Different leaks require different technology. Leaks are found a number of different places in the system. Commonly found issues include: O-rings seals, metal gaskets, shut-off valves with through-flowing leaks, internal welds on utility pipes,long chamber welds, and even flange porsity. Often leaks are so severe that pumping down to a required range can be a challenge. We have experience in setting up a test correctly, and executing it. Your testing will be completed and your leaks will be found to your specifications.
