PIV – Pipe Isolation Valve
It is sometimes necessary to install a new PIV and the ideal solution is to do that with the least disruption to customers.
Steve Vick International have worked with Cadent Gas to design a way of successfully installing a new PIV, for 2” steel or below, under ‘live’ conditions using Steve Vick Live Gas Service Isolation and Live Service Transfer. Using this method, it is possible to install the new PIV without disruption to consumers’ supplies which therefore negates the need to test, purge and relight each dwelling.
To introduce a new PIV, operatives are required to install two UPT’s onto the pipe and install a new permanent bypass, which already has the new PIV incorporated. Once this has been completed it allows the old pipework to be flow stopped and removed using one of the following techniques: SVI Live Service Isolator, Foam Stop or Rapid Service Isolator.
Steve Vick International offer this as a contract service, using their highly experienced engineers.
