This guide aims to explain the basics of pipe lining, detail the essential equipment for its implementation, and clarify the key criteria for making a wise choice. Thus, you can rehabilitate your drainage systems effectively while maintaining peace of mind.

Understanding pipeline lining

Pipe lining is an effective method to rehabilitate damaged drainage networks without requiring complete replacement. This technique involves creating a new solid and waterproof internal coating, using resin or liner.

This method offers multiple advantages: it is economical, quick to implement, environmentally friendly, and ensures increased longevity.

The advantages of lining

Pipe lining offers several benefits, notably:

  • Time and money savings: It eliminates the need to dig up, remove, and replace pipes, thus reducing associated costs such as equipment rental, waste disposal, ground repair, etc. This technique also reduces noise pollution, traffic disruptions, and accident risks.
  • Environmental protection: It limits ecological impact by reducing waste production, energy and water consumption, as well as CO2 emissions. Additionally, it helps prevent leaks that can contaminate soil and groundwater.
  • Performance improvement: Lining increases the mechanical and chemical resistance of pipes against corrosion, abrasion, roots, rodents, etc., and improves flow by eliminating irregularities and pipe constrictions.
  • Guaranteed longevity: This method extends the lifespan of pipes, providing them with new sealing and strength. Depending on the materials used, this duration can exceed 50 years.

The different types of lining

Various methods are available, distinguished by their application technique and the type of pipes concerned:

  • Resin spray lining: This approach consists of spraying an epoxy resin inside the pipes via a robot, forming an adherent layer. Suitable for small to medium diameter pipes, it effectively handles bends and section variations.
  • Slip lining: This method involves inserting and expanding a flexible resin-impregnated liner against the internal walls, thus creating a new pipeline inside the existing one. It is suitable for medium to large diameter pipes, for straight segments and gentle curves.
  • Spray lining: It consists of spraying an epoxy resin with a gun, forming a thin and smooth layer. Ideal for small diameters, this technique allows handling bends and section changes.

Selection criteria for a lining project

To choose the most suitable lining technique, consider:

  • Type and condition of pipes: Understanding the material, diameter, length, shape, and level of degradation is crucial.
  • Technical and regulatory constraints: It is important to verify project feasibility, especially pipe access and the need for authorizations.
  • Budget and deadlines: Comparing costs and durations of different options while considering additional expenses is crucial.
  • Provider quality and guarantee: Ensuring the professionalism of the chosen company through its references, certifications, insurances, and warranty duration is essential.

Essential equipment for successful lining

The success of pipe lining depends on using suitable and efficient equipment. For each lining methodology, depending on the pipe diameter and the desired finish level, there is a set of specific equipment. Discover here the main equipment needed for quality lining, grouped into three categories: pipe preparation equipment, lining systems, and control and finishing equipment.

Pipe preparation equipment

Preparation is a key step before lining. It involves cleaning, inspecting, and unblocking pipes if necessary. Here is the essential equipment for this stage:

  • Inspection camera: essential for assessing the internal condition of pipes, detecting anomalies, leaks, or connections. It can be manual, motorized, or mounted on a robot.
  • Hydrocleaner: a major tool for cleaning pipes using a high-pressure water jet, capable of removing deposits, grease, and roots. It is often complemented by various accessories such as nozzles, chains, or brushes.
  • Unblocker: allows removal of blockages caused by debris or other obstructing elements, available in mechanical, electric, or pneumatic versions.

Lining systems: Spray, CIPP, and other technologies

Once the pipes are ready, lining can begin. Depending on the needs, different systems can be used:

  • Resin projection system: ideal for spraying epoxy resin into small to medium diameter pipes. Uses a robot or a gun to apply the resin which, once cured, creates a solid and durable coating. Perfect for treating bends and changes in section.
  • Lining system: involves inserting a resin-impregnated liner inside the pipe, then expanding it so that it perfectly fits the walls. After the resin hardens, a new pipe is formed, suitable for medium and large diameter pipes.
  • Spot repair system: local repair solution for damaged pipes, applying resin or liner to the affected area. An effective method for spot repairs without the need to fully line the pipe.

Control and finishing equipment

The final step of lining consists of verifying the quality of the coating and performing the finishing touches. The following equipment is essential:

  • Inspection camera: allows checking the condition of the coating, ensuring its uniformity and watertightness. The same camera used for preparation can be employed.
  • Milling robot: used to clear connections covered by the coating, equipped with various cutting tools. It is often the same robot used for resin spraying.
  • Leak test: essential to confirm the absence of leaks in the coating, performed by applying air or water pressure according to standards.

Making the right choice: parameters to consider

To select the pipe lining equipment that best meets your requirements, it is essential not to limit yourself to knowledge of the different available technologies and equipment. Other factors must be considered, directly influencing the quality, efficiency, and profitability of your renovation work.
