Internal pipe lining, also known as pipe relining, is a revolutionary trenchless technology designed to rehabilitate damaged or aging pipelines without the need for costly and disruptive excavation. At Lined Pipe Systems (LPS), we specialize in delivering high-performance internal lining solutions that not only restore pipelines but also extend their service life dramatically.
Whether you’re dealing with corrosion, cracks, or root intrusion, LPS has the tools, technology, and expertise to provide long-term protection and durability through our industry-leading joint systems and polymer linings.
What is Internal Pipe Lining?
Internal pipe lining is the process of installing a new “pipe within a pipe” by inserting a flexible, resin-saturated liner into the existing pipe. Once in place, the liner is cured using heat or UV light to create a solid, corrosion-resistant barrier that seals off damage and restores flow capacity.
This method is especially ideal for pipelines that are difficult to access or located beneath buildings, roads, or critical infrastructure. With internal lining, there’s no need for digging or replacement, making it a cost-effective, minimally invasive solution.
How Internal Pipe Lining Works
At Lined Pipe Systems, we use a meticulous multi-step approach to ensure we line each pipeline with precision and durability:
Inspection and Cleaning
We begin by inspecting the pipeline with high-resolution cameras to identify cracks, blockages, and corrosion. Next, we clean the pipe thoroughly using hydro-jetting or mechanical methods to remove debris, rust, and scale.
Liner Installation
We saturate a felt or fiberglass liner with epoxy resin and insert it into the cleaned pipe through existing access points. We then maneuver the liner into position using air or water pressure.
Curing the Resin
Once in place, we inflate the liner to press it firmly against the walls of the host pipe. We then apply heat or ultraviolet (UV) light to cure the epoxy resin, forming a seamless, jointless interior lining.
Finalization
After the resin cures, we remove the bladder used for inflation, leaving a brand-new pipe within the old one. The newly lined pipe is now ready to operate efficiently, with improved resistance to corrosion, leaks, and wear.
Premium Materials Used by LPS
At Lined Pipe Systems (LPS), we employ only the highest quality materials to ensure maximum durability and compatibility across diverse pipeline environments.
Epoxy Resins
Used for their excellent adhesion, strength, and chemical resistance, epoxy resins are a cornerstone of modern internal pipe lining.
Felt or Fibreglass Liners
Flexible and resilient, these liners can adapt to the contours of the host pipe while providing structural integrity and long-lasting performance.
Advanced Polymer Linings
LPS specializes in thermoplastic polyurethane, polyamides, fusion bonded epoxy, and rubber/polyurethane hybrid linings, each selected based on the application—be it water pipelines, slurry lines, or chemical transport.
Advantages of Internal Pipe Lining with LPS
When you partner with Lined Pipe Systems, you’re not just choosing a product, you’re investing in a long-term pipeline solution.
Trenchless Technology
No need for disruptive excavation. Our system allows pipe rehabilitation from the inside, preserving landscapes, roads, and infrastructure.
Cost-Effective
Internal pipe lining eliminates the high labour and equipment costs associated with traditional pipe replacement. You save on both time and money.
Long-Lasting
Our epoxy and polymer linings resist corrosion, root intrusion, and chemical damage. Expect decades of leak-free performance.
Versatile Applications
From oil & gas to mining slurry and domestic wastewater, LPS solutions are compatible with various industries and pipeline sizes.
Reduced Downtime
Fast installation and curing times mean your operations are back up and running quicker than traditional methods allow.
Future-Proof Infrastructure
Our technology reduces maintenance requirements, saving resources over the pipeline’s extended life.
When Should You Consider Internal Pipe Lining?
Pipe lining is ideal for:
- Cracked or collapsed pipes
- Corroded steel pipelines
- Root-intruded pipes
- Aging infrastructure with frequent leaks
- Pipelines in sensitive or urban areas where digging is impractical
Why Lined Pipe Systems (LPS) is the Industry Leader
With decades of innovation, Lined Pipe Systems offers technologies that redefine what’s possible in internal pipe lining. Our unique welded joint systems such as FlexSleeve®, SealSleeve™, and the CCB® Sleeve are engineered to handle everything from thin linings to high-pressure pipelines with precision.
FlexSleeve®
Perfect for thin linings, offering flexibility and a high-quality weld finish even in large diameter or out-of-round pipes.
SealSleeve™
Designed for rubber and PU linings, this technology allows full-penetration welded joints that are stronger and longer-lasting than mechanical joints.
CCB® Sleeve
With a proven 25+ year case history, this sleeve is ideal for smaller diameters and provides superior sealing against internal corrosion.
By integrating these advanced sleeve systems, LPS enables the use of standard carbon steel pipe, ensuring strength, ductility, and long-term corrosion protection through internally applied linings.
Common Applications for LPS Internal Pipe Lining
Our technology is widely used across various industries:
- Oil & Gas – Sour and sweet crude pipelines
