Helium leak testing is the most sensitive method to detect leaks, before they reach the critical stage, available to industry today. Helium is the lightest inert gas. It is non-toxic, non-hazardous, non-destructive, and it easily penetrates small leaks. As helium has one of the smallest molecular size, it is able to pass through leak openings before they become large enough to leak other hazardous materials such as chlorine.
EXCELGAS offers Helium Leak Testing services for tubing systems and vessels upto a range of 1 X 10 -11 cc / sec of Helium. We have state of the art ALCATEL France make helium leak testing machine. Onboarf and inline leak testing can be carried out with the machine. We have fully trained NDT inspector to SNT-TC-1A 2001 – Level II, which enables us to develope procedures, interpret results of inspections carried out and compile reports based upon any such findings.
Applications:
- Piping Systems Leak Detection
- Vessels Leak Detection
- Industrial Installations
- Instrumentation
- R& D

- sniffing mode
- Minimum detectable helium leak 1 X 10-7mbar.l/s
- Response time < 1 s
ACCEPTANCE STANDARD
Prior to testing any unit or system an acceptance standard must be established. All units will leak (or bleed) so it is important to establish the acceptable rate of leakage which will allow the unit to operate safely. Most product leaks are 10-6 std cc/sec or larger.
Reasons for Using Helium Leak Testing Equipment
Helium leak testing has the versatility and ability to detect minute leak in a variety of applications throughout industry. The leak testing equipment is portable, making field testing in remote areas a relatively simple matter.
Using standard helium leak testing procedures, adapted to individual needs, leak can be accurately located and measured. If leak are located these can be repaired and retested by the same method while still on site.
Helium leak testing is a worldwide recognized method of non- destructive. Testing can be performed to the latest specifications and guidelines. Helium leak testing can help prolong the life of piping / tubing systems, ensure the safety of personnel and decrease downtime due to lost production thereby reducing overall costs.
