Ticking all the boxes

Channeline is delivering sustainable pipeline rehabilitation with its versatile and bespoke lining solution.

Pipeline projects are becoming increasingly complicated in modern urban environments thanks to population density, rising operational costs, and the push for sustainable business practices. Fortunately, Channeline has a pipeline lining solution to tackle all three of these issues.

Channeline has distinguished itself in the pipeline sector with its bespoke structural glass reinforced plastic (GRP) lining systems since the 1980s.

The technology has come a long way since in that time and today is available as a unique multi-segmental solution that allows the liners to be assembled on-site.

It can also be manufactured in tailored shapes and sizes to suit even the most niche of pipelines.

This fully structural lining solution is suitable for the rehabilitation of sewers, tunnels, culverts, stormwater and other buried structures. But in a busy urban environment, access points to these assets are often small, with the cost of excavation and refacing streets in turn incredibly high. Enter Channeline’s lining solution.

“This technology allows installers to transport our liners through access points that are smaller than the diameter of the actual sewer that is being repaired,” Channeline Quality Assurance and Quality Control Manager Dr Dev Chelot said.

“This means that no additional excavation is required. The segments can simply be brought into a small access point and assembled and installed inside the sewer or tunnel.”

With a design life of 150 years, Channeline’s multi-segmental lining does not yield any ground when it comes to strength. In fact, Chelot said the product is much stiffer than traditional single piece pipes.

“We designed the lining system in a certain way so that the load-carrying capacity of the joints increased,” he said.

“It takes more load to deflect a multi-segmental pipe than to deflect single piece pipe.”

Beyond longevity, Channeline can also help businesses drive down operational costs and carbon emissions.

“We’re reducing the fuel cost for transporting the pipes, because if five trucks are needed to transport single piece pipes, Channeline may only require one or two trucks to transport our multi-segmental pipes of the same geometry,” Chelot said.

“Additionally, minimal excavation work is required to install the Channeline product.

“So in these ways, we’re saving carbon emissions by reducing fuel consumption and driving down overall costs.”

Putting the pieces together

Channelbond is a meticulously engineered structural adhesive that brings the entire multi-segmental package together. Designed and produced by Channeline to assemble its multi-segmental lining, the adhesive is resistant to 14 different chemicals and is suitable for use in acidic environments.

According to Chelot, Channelbond was designed to give contractors greater control over the installation process.

“We set out to make an adhesive that is both mechanically strong and simple to apply,” he said. “Most of the adhesives in the market are all temperature controlled, which means that the curing time is massively dependent upon temperature.

“But our product allows contractors to adjust the mixing ratio, which can make curing time longer or shorter as required.

“For example, if a contractor wants to cure a section in 20 minutes, all they have to do is adjust the mixing ratio as per what we recommend.”

Channeline’s multi-segmental technology, working in unison with Channelbond, is giving contractors and asset owners greater control over their pipeline projects, while also driving down costs and carbon emissions.
