Helium Filter Leak Testing

In house helium leak testing is performed by submerging the filter housing into deionized water, raising helium pressure to the desired testing specification and observing sealing surfaces and welds for bubbles. This method of detection is valid to a leakage rate of 1x10-4 cubic centimeters per second at standard temperature and pressure. Testing is typically performed for 1 minute in increments of 25%, 50%, 75%, and 100% of the working pressure. Our in house test stand operates up to 22,500 psi and all data is electronically logged.
