Commercial Gas purging / Decommissioning
It's in the name
Natural Gas and L.P.G Purging Services
At Purge point Installations, we provide a full range of natural gas purging and decommissioning services for commercial and industrial pipework. Whether you're modifying an existing system, preparing for demolition, or commissioning a brand-new line, we ensure gas is safely removed or introduced in full compliance with industry standards.
Safe, Controlled Gas Removal
Purging isn’t just about clearing a pipe — it’s about doing it safely and effectively. Depending on the size and complexity of the system, we use:
- Inert gas purging (typically nitrogen) to displace natural gas from pipework
- High-powered air compressors to clear larger or long-distance lines, sometimes a venturi is viable.
- Flaring (controlled burn-off) when required for safety or system size or type of gas.
For decommissioning, it's critical to remove all residual gas — especially before demolition or pipework alterations.
Why Purge Velocity Matters
Maintaining the correct purge velocity (QP) is essential. If velocity is too low, the purge gas may not mix correctly, leading to stratification — where inert gas flows over the top of the natural gas without fully clearing it. This results in an incomplete purge and a potential safety risk.
Our engineers calculate the correct purge rate for every system and confirm safe removal using calibrated Gasco Seeker detectors.
Certified & Compliant
Every purge operation is verified with:
- Documented purge calculations
- Gas detection confirmation
- A full Purge Certificate issued on completion
For new systems, we also carry out purging to gas (commissioning of pipework), ensuring your line is safely filled within upper and lower flammable limits and fully certified.
