Thin walls are always better

Fiberglass reinforcement gives you a liner in a strong and thin material. Strong and thin is a fantastic combination because you keep the pipe’s cross-sectional area and flow capacity. Fewer materials are used and we avoid transporting unnecessary goods.

There are no advantages to unnecessarily thick pipe walls!

Be careful about the diameter

There will always be a gap between the existing pipe and the new liner. It is important that the gap is as small as possible because it consists only of air, reducing flow capacity, which can cause problems with leakage in wells and joints. The smaller the gap – the better!

The gap for Inpipe liners is extremely small, at less than 0.1% of the diameter.

Full capacity in treatment plants and pipelines

Inpipe liners greatly reduce the risk of infiltrating groundwater that robs capacity in pipelines and treatment plants. The minimal gap also effectively stops roots and soil from entering.

Better flow and fewer stops

According to tests, Inpipe liners have a surface similar to polished steel. The advantages are low friction and little turbulence in flowing water. The fine surface without joints between pipe sections also means that debris and other materials easily follow the water flow. The risk of dams and stops in the pipe is drastically reduced.

UV curing

Curing with ultraviolet light is a safe, effective, and fast method for curing a liner. This means a lot to you as a line owner and also to the installer, in terms of energy consumption, efficiency, quality, and that the line is quickly ready to be used again.

Can handle ground movements

In soils exposed to frost, subsidence, and soil movement, the pipes must be flexible to prevent damage. Inpipe’s liner is able to compress up to 30% and then return to its original shape, all while maintaining strength and longevity. The liner is also able to bend and stretch.

Inpipe’s liners are so strong and flexible that they have been chosen in earthquake-prone areas around the world.

High tensile strength provides safer road culverts

Roads and railways expose culverts to vibrations and high loads, which means that over time, pipe sections slide apart from each other. To counteract this, tie rods are mounted inside culverts. Unfortunately, this usually happens already when the damage has occurred and the pipes have slipped apart, with the resulting penetration of water, gravel, and roots.

If you install an Inpipe liner, you get both a tight and draft-proof culvert. Inpipe’s liners are tested for tensile strength. For example, an Inpipe liner Ø 800 × 6.0 mm can handle a traction force of 300 tons. The minimal gap and the ability to expand completely into joints and nooks means that the pipe sections are locked in place and cannot slide apart.

Withstands high internal pressure, flushing, and abrasion

Inpipe liners are able to withstand an internal pressure of 46-48 bar before damage occurs. Inpipe liners are also tested and approved for high-pressure flushing and abrasion.
