  These overhead mains, situated close to a gas holder in Stoke-on-Trent, were being dismantled prior to the site being developed for housing. The pressure was reduced from 2 bar to 50mbar, allowing a Steve Vick International Special Contract Service team to install two FOAMBAGS™ in the 20” and 24” diameter pipes. The pipes could then be cut out and dismantled.
