Fuel Pipe Helium Leak Test System

Machine supplied: Fuel Pipe Helium leak test system

Client: Leading Global Aerospace Technology Company

Part: Fuel Pipes for the Aerospace Sector

Overview: This pressure and leak test system is used for production acceptance testing of composite fuel pipes, in a range of types, diameters, and lengths. TQC supplied this pressure testing and helium leak testing solution to meet an overall production rate of 15 parts per hour

This leak test fixture is based on the standard Series 20 drawer concept, this type of solution is suitable for automatic leak testing of small to medium-sized parts.  The benefits of using a high vacuum helium leak test are that it is more accurate, more sensitive, a faster test, and uses less helium test gas.

This system allows the operator to load the tooling with a fuel pipe, securing 2 off end clamp units, followed by automated testing. The fixture is advanced into the test chamber, and a door then closes and seals the test chamber.  The automated test begins with a high-pressure proof test and if successful moves on to the helium leak test. On completion of the testing the chamber and part vent to ambient followed by opening of the chamber door and transfer of the test piece ready for manual unloading.
