Purging and testing of gas installations
We purge new and existing gas installations to IGEM/UP/1, IGEM/UP/1A and IGEM/UP/1B, including tightness testing and safety checks, with full documentation for your compliance records.
What we do
Purging removes air or gas from pipework safely so an installation can be put into or taken out of service. We purge and test to the relevant IGEM standard for the installation and record the results.
- Purging of new and existing installations
- Tightness testing
- Safety checks before the installation is put back into use
- Purge records and test results provided
Standards we work to
Which standard applies depends on the size and type of installation. In short:
- IGEM/UP/1: strength testing, tightness testing and direct purging of industrial and commercial gas installations
- IGEM/UP/1A: tightness testing and direct purging of small low pressure industrial and commercial natural gas installations
- IGEM/UP/1B: tightness testing and direct purging of small installations of the size found in domestic premises
We are qualified for non-domestic testing and purging to IGEM/UP/1 with a maximum operating pressure up to 16 bar.
