At an Australian potato chip factory, five new concrete tanks containing low concentration cooking oil were installed with permanent seals to six core holed pipe penetrations. 

The client required an instant permanent solution to seal six core holed pipe penetrations to accommodate new HDPE pipework passing through the tank walls. 

The tanks and penetrations are now buried underground, so it was of the utmost importance that the tank remain leak free and sealed using the appropriate materials providing a reliable long-term seal solution in these harsh conditions.

Projex Group offers professional advice and calculations in selecting the right Link-Seal sizing and model to best suit the substances in contact with the seals. The Link-Seal model “O” was selected for this project as it is resistant to oils and suitable for highly corrosive environments.

There are numerous benefits in using Link-Seals for these applications. Link-Seals have no down time on curing and unlike other products they do not shrink whilst curing. Link-Seals are maintenance free after application, but if a leak occurs due to excessive pipe movement, Link-Seals can be tightened and adjusted.
