UV Curing Technology

The typical installation process of Interline® UVliner into the host pipe, which is then gradually infl ated with compressed air until fully expanded. At this point a UV light train is pulled through at a controlled speed, curing the pipe as it travels.

By using UV light the installation footprint is quite small when compared to traditional CIPP lining as the consumption of energy during curing phases is signifi cantly lower compared with traditional curing systems e.g. the use of hot water or steam. This is not only an important cost consideration but also a signifi cant environmental consideration particularly with regards to the reduction of CO2 emissions.

Since the liner is cured via UV light, once cured, there are no contaminates like styrene to be discharged

Safety

Interfl ow strongly encourages safe work practices and protecting the safety of the community and our workers is our priority.

 The use of  UV eliminates the use of hot water or steam to cure the liner resulting in a safer rehabiliation delivery option when compared to other products on the market.

Interflow has applied its successful safety management systems to this product and process. Our policy of aiming to have zero harm on the environment, community and our workers is continued with UV cipp.

Experience

Jinjiedong has been using trenchless products to renewpipelines since 2002 and remains committed to providingproducts and services that offer the greatest value to itsclients.  UV cipp is the latest addition to the suite ofpipeline rehabilitation products offered by Jinjiedong With the addition of UV cipp Interflow can now offera competitive trenchless solution in a wider range of circumstances.

UV cipp was determined as the best solution for thisrenewal as the pipeline was situated in a challenging urbanarea with difficult access, requiring a small site set up.

Having a pipe depth of 20 metres also meant that greaterstrength from the liner was required and standard CIPP feltcould not be made stiff enough.As such the new UV cipp liner was the only product capable of meeting theexact requirements of this job.

The project was completed in accordance to the client's specifications and plan. The  pipe was renewed withonly minimal disruption to residences or the community and no impact on regular week day road users.
