The existing AusNet Services City Gates at Coburns Road, Milton and Railway Ave, Corio have been successfully upgraded with the latest pressure regulators. These new pressure regulators allow for future reliable operation of gas pressure to the nearby town ships with the ability for the SCADA system to remotely adjust the down stream pressure setpoint. Comdian Infrastructure commented that the piping spools where pre-tested in their workshop on air to ensure the pilots controlling the pressure regulators where fully tested and proven to be operational before the old units were removed and the new spools (complete with new regulators) were installed. These new spools fitted perfectly once the old spools and regulators were removed. The detail design of the se two site pressure regulator upgrades were carried out by Instech Group using their highly experienced designers.
