InsituMain Pressure Pipe: Is It Right for Your Water Project?

Older water pipes are more likely to crack, corrode or leak, especially when constantly exposed to high internal pressure. 

But repairing a damaged waterpipe is just one step in the process. Before a pipe can be repaired, the damage needs to be identified, located, and isolated; all of which are processes that take time and leave local homeowners and businesses without their water supply.

In large, high-pressure mains systems, time matters. Every delay can impact homes, businesses and essential services. That’s where the InsituMain Pressure Pipe lining comes in. Engineered to withstand high internal pressure and adapt to varying pipe sizes and materials, InsituMain offers a trenchless solution for fast, efficient pipeline rehabilitation, without excavation.

Here’s how it works and why it’s trusted in modern water infrastructure projects.

What is the InsituMain Pressure Pipe System?

The InsituMain Pressure Pipe system is a trenchless solution developed by Insituform, a pioneer in CIPP (Cured-In-Place Pipe) technology. It is designed specifically for repairing and rehabilitating high-pressure water mains without excavation or removal. 

This CIPP lining solution works by being inserted into the damaged section of pipe and then activated remotely using hot water or steam. Thermosetting resin is drawn out of the pipe and cured against its inside walls, before the pipe is given time to cool, the ends are trimmed, and it is returned to everyday use.

From a consumer perspective, InsituMain works in much the same way as any other Insituform CIPP solutions. The difference is that this particular solution is compatible with a broader array of host pipe materials, allowing for the rehabilitation of various pipe types, including cast iron, ductile iron, steel, asbestos cement-reinforced concrete pipe, and thermoplastic. It can also safely handle high pressures inside the pipe and navigate complex bends and challenges.

Key Features of InsituMain

Other key features of InsituMain’s CIPP liners include a diameter range from 20 cm to 1.2m, the ability to handle extreme internal pressure over 250 PSI, a flexible design which can negotiate bends up to 45º, and resistance to corrosion and leakage.

This range of features not only equates to a wide range of practical applications but also ensures minimal disruption to those who live and operate their businesses in the local area. It’s incredibly important for local infrastructure and the local economy that dropped water pressure does not become a lasting issue, and so a fast return to regular service is crucial.

Benefits for Water Infrastructure Projects

Those who have used Insituform in the past will already know that, as the founding organisation behind CIPP liners and the ability to rehabilitate damaged pipes, sustainability and efficiency remain at the heart of every product we offer.

InsituMain has been created to reduce the reliance on costly excavation, instead ensuring that pipes can be restored to full use without needing to break ground. Not only does this save a huge amount of cost on equipment hire and engineer time, but it also supports sustainability and environmental goals.

It also represents a solution which is simply more practical. Digging up, exposing, removing and replacing pipes is, in many scenarios, simply not practical. And so having a solution like InsituMain ensures that pipes can be restored using a product which is versatile, adaptable, and reliable.
