Our customer sought to replace an outdated water dunk testing system with a fully automated helium accumulation test for fuel pipes solution that increased uptime, reliability, and flexibility. In addition to automated calibration and validation, they required the ability to perform “audit” leak tests at 100 times greater sensitivity than the production reject limit. Additional needs included custom tooling that could be easily upgraded or modified with minimal cost and effort.
We engineered a custom helium accumulation system featuring a unique gas recirculation system. With a standard tooling platform that enabled simple chamber and fixture upgrades, and two systems using a single leak detector, we engineered a system that produced increased reliability and significant cost savings.
