We carry out comprehensive diagnostics of various types of installations in order to detect and locate leaks. The diagnostic method is selected individually for each project depending on type of the installation.
PRESSURE AND HYDROSTATIC TESTING
- System heating and water pressure testing up to 1600 Bar
- Oil testing and flushing for pressure range up to 100 Bar
- Compressed air, nitrogen or helium for pressure up to 150 Bar
- Hydrostatic tests for open top systems
TRACER-GAS LEAK TESTING METHOD
Leak testing method using helium or nitrogen tracer-gases allows
to determine precisely location and size of the actual leak. It is applied
for vacuum installations but also for nitrogen, compressed air and
refrigeration installations, wherever the tightness of the installation is of
key importance.
Leak detection by pressure method with probes up to 50m long allows quick and efficient access to hard reachable areas. Detection with tracer-gas provides fast detection of leaks without long lasting process shutdowns. The level of leakage detected in field conditions reaches up to 10- 9 mbar • l/s.
ACOUSTIC EMISSION METHOD FOR DEFECT DETECTION
Acoustic emission (AE) is an effective non-destructive detecting technique for defect detection in various installations. It is based on the sound measurements generated by the material. This sound emission usually occurs in situations, where the object is subjected to a load (mechanical or thermal) which causes distortions. This method allows to detect and determine the exact location of existing defects in the installation structure, such as material defects, welding defects, leaks or corrosion points. Measurements and analysis of acoustic emissions are most often used for pneumatic and hydraulic installations, as well as for liquid and gas tanks and pipelines. The use of this non-destructive testing method provides detection of damages such as cracks, leaks, plastic deformations and corrosion. It allows to avoid expensive production outages and is suitable for leaks up to 10-3 mbar • l/s.
