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. The hot tap 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.

Where a hot-tapping is required, an application must be made to Energy Safe Victoria (ESV) for authorisation, and work must not commence until authorisation has been given. The gasfitter must submit an “Application for Acceptance of Complex Gas Installations and Type B Gas Appliances” to ESV. This is a requirement of the Gas Safety (Gas Installation) Regulations 2008. Also the gasfitter will need to provide a signed Compliance Notice and may need to provide a test report.

Refer to, Division 4, Clause 26.
