Gas information sheet 02: Hot-tapping of consumer piping

View as PDF.

Hot-tapping is a procedure that makes a new pipeline connection while the pipeline remains in service, without isolating the gas supply or requiring purging.

This procedure involves attaching a branch connection and valve on the outside of an operating pipeline, and then cutting out the pipe-line wall within the branch and removing the wall section through the valve. This avoids product loss, emissions or disruption of service to customers.

Due to the complexity and risks associated with this type of work not all gasfitters are competent and equipped to perform such work. As a result, prior to carrying out hot-tapping work gasfitters must first apply to Energy Safe Victoria (ESV) for authorisation to perform this work.
