Visit pipe lining offers an innovative solution for repairing corrosion-damaged pipes without the need for total replacement. The technique involves inserting a polymer resin lining inside existing pipes. Once in place, this lining creates a new coating that is both strong and impermeable.
Compared with traditional pipe replacement, which involves extensive and costly work, lining is an advantageous alternative. Not only does it reduce the inconvenience and time involved in the work, it also cuts costs and increases the longevity of drainage systems. In this article, we explore how corrosion deteriorates pipes, demonstrate how lining can solve this problem, and outline the main stages in the process.
Understanding the impact of corrosion on pipelines
The main causes of pipe corrosion
Most pipe corrosion is caused by water coming into contact with metal or copper pipes, triggering a natural oxidation reaction. Elements such as pressure, temperature, water quality, certain chemical treatments and the presence of bacteria can accelerate this process.
Signs and consequences of corrosion in piping systems
Symptoms of corrosion include material deterioration, manifested by pitting, cracks, deposits or rust. Although these signs may appear on the outside of pipes, an internal video inspection can also reveal them. The negative effects of corrosion on piping systems include leaks, ruptures, reduced flow, contamination, health hazards and damage to connected devices.
Pipe lining as a solution to corrosion
What is pipe lining?
Pipe lining offers an effective method of repairing pipes affected by corrosion without the need for complete replacement. This technique involves introducing a polymer resin liner inside existing pipes, creating a new, solid, impermeable internal lining.
How does the liner prevent and treat corrosion?
This method effectively prevents and combats corrosion by establishing a protective layer that isolates the water from the pipe material. The resin applied is designed to resist oxidation, chemical agents, bacterial attack and root intrusion, while restoring the pipe's original integrity and watertightness.
Advantages of lining over other repair methods
Pipe lining distinguishes itself from other repair approaches such as complete replacement or lining by its less intrusive nature - no need to excavate or demolish adjacent structures.
What's more, this technique is faster, taking just a few hours to complete, and more economical, significantly reducing expenditure on labour, materials and subsequent repair work.
Finally, lining is also advantageous in terms of durability, offering an average life extension for pipes of around 50 years.
Key steps in the lining process to combat corrosion
Pipe diagnosis and preparation
To begin lining, it's essential to diagnose the condition of the pipe to be repaired. This is done using an inspection camera, capable of detecting damaged areas, cracks, blockages or leaks.
Once the diagnosis has been made, it's crucial to clean and prepare the pipe to remove any impurities, roots or debris that may interfere with resin adhesion. This is achieved either by high-pressure water jetting, or by using a milling robot.
Liner application and curing
The next phase involves applying the liner to the inside of the pipe. This lining consists of a sheath, made from fiberglass or felt, which is saturated with polymer resin.
The sheath is applied either by traction or inversion, depending on the technique adopted. The resin is then cured using either heat or ultraviolet light, depending on the type of resin used.
In this way, the lining creates a new, solid and impermeable inner lining for the pipe.
Post-lining inspection and long-term maintenance
The final step is to check the quality of the new lining. To do this, an inspection camera is again used to check the new lining's impermeability, strength and conformity. A milling robot is also used to unblock the connections.
Finally, we recommend that you keep your lined pipe in good condition through regular maintenance. We recommend a video inspection every 5 years and a thorough cleaning every 10 years.
In a nutshell
This article has given you an in-depth understanding of pipe corrosion, its impact on your drainage systems, and how pipe lining offers a solution. An innovative, fast, economical and long-lasting method, pipe lining repairs damaged pipes without replacing them.
It involves inserting a resin liner into the pipes to create a new, solid, waterproof coating. The multi-stage process requires the expertise of a qualified professional.
