Cured in Place Pipe

Cured-In-Place Pipe or CIPP lining systems are trenchless technologies used for rehabilitating and repairing underground pipelines. These systems involve the insertion of a resin-impregnated liner or resin-saturated flexible felt into the existing damaged pipe. This can normally be done from existing manhole covers or exterior access points, followed by the curing of the liner to create a new, structurally sound pipe within the old one. CIPP lining is a cost-effective and less disruptive alternative to traditional pipe replacement methods and has little disruption to traffic without the need to dig up roads

One of the most common types of CIPP is Ambient Cure lining, ideal for repairing short lengths and requires minimal equipment to complete. However, due to the time constraints of the resin drying ambient cure is not suitable for long pipes.

The lining process requires inverting or pulling a resin-saturated flexible felt or fibreglass liner into the damaged or degraded pipe. This process is usually done from an existing manhole or chamber access in the lateral system, inside a house or at an exterior point. Inflating the liner with air pressure then transports the coated liner through the damaged pipe, flexing around bends to press against the inside walls. After the liner system is in place, the system can be cured by hot water, steam, or ultra-violet (UV) light, the cured liner then creates a seamless, durable pipeline within the existing pipe.

CIPP methods offer pipeline engineers the option to significantly extend the life expectancy of an existing pipeline without the need to remove the old pipeline from its route, whether this is a buried pipe, a surface network, or a pipeline within a building.

Sewer and Stormwater Pipelines

CIPP lining is widely used in municipal and industrial applications to rehabilitate deteriorated or damaged sewer and stormwater pipelines. It can address issues like cracks, corrosion, infiltration, and exfiltration.

Potable Water Pipelines

In some cases, CIPP lining can be used to rehabilitate potable (drinking) water pipelines. Special considerations and materials must be used to ensure the liner is safe for contact with drinking water.

Industrial Pipelines

CIPP lining is applied in various industrial settings, including chemical plants, refineries, and manufacturing facilities, to repair and upgrade process pipelines.

Gas Pipelines

For non-pressurized or low-pressure gas pipelines, CIPP lining can be used to rehabilitate sections with structural issues or damage.

Trenchless Culvert Rehabilitation

Culverts, which are often used to manage water flow under roads and highways, can be rehabilitated using CIPP lining systems to extend their lifespan and maintain proper functionality.

Residential and Commercial Plumbing

CIPP lining is used in plumbing applications to repair damaged or deteriorated pipes within residential and commercial buildings, including sewer and drain lines.

Infrastructure Repair and Upgrades

CIPP lining can be used to extend the life of aging infrastructure, such as bridges and tunnels, by repairing or reinforcing drainage systems.

Petrochemical and Chemical Plants

In industrial settings, particularly petrochemical and chemical plants, CIPP lining is used to rehabilitate and maintain pipelines carrying various fluids and chemicals.

Wastewater Treatment Plants

CIPP lining is employed to rehabilitate pipelines within wastewater treatment plants, helping to maintain proper sewage and effluent transport.

Mining and Quarry Operations

– In mining and quarrying operations, CIPP lining can be used to repair and reinforce underground pipelines used for the transport of minerals, water, and other materials.

CIPP lining is valued for its ability to minimise disruption to traffic and surrounding areas since it doesn’t require extensive excavation. It’s an efficient method for rehabilitating pipelines, extending their lifespan, and reducing the overall cost of maintenance and repair. Specific applications and the materials used in CIPP lining may vary depending on the type of pipeline and its intended use.
