Relining of pipe: What It Is And How To Get One Done

Relining pipes is a process used to fix or restore the interior surfaces of metal pipes, typically cast iron ones. It involves putting a layer of refractory material inside the pipe and welding it to create a watertight seal. The pipe relining process is used primarily in the oil and gas industry to repair or restore pipes that are found broken or cracked, and to provide extra strength. Pipe relining is also a variation of the process that finishes metal pipes that have been previously clad.

What is Relining of pipe?

  • Relining of pipe is repairing cracked or broken pipelines by filling the gaps and cracks with a proprietary mix of resin and filler. The goal is to restore the pipeline to its original condition while preventing future leaks.
  • Relining of pipes is typically done with plastic pipes, but it can also be done with copper, steel, or other materials.
  • The process begins by locating the pipe in question. Next, a camera is used to survey the area for damaged areas. These areas are then pinpointed and marked for treatment. Next, a special scanner is used to determine the size and shape of the gaps and cracks. Finally, the pipe relining technician prepares the mixture and fills the gaps and cracks using a hand-held applicator gun.

Why Should You Get a Relining?

Relining of pipe can improve your system’s performance, prolonging the life of your pipe and equipment. Relining is also an important safety precaution since it can reduce the risk of leaks and failure.

How Long Does It Take to Replace a Pipe?

A relining project can take anywhere from a few hours to a few weeks, depending on the size and complexity of the job. Here’s what you typically need to know to get started:

Tools and Materials:

-Relining kit (consists of a variety of tools and supplies needed for the job, including a jigsaw, saws, chisels, and sandpaper)

-Pipe cleaner


-Tape measure

-Ruler or a straight edge

-Cordless drill with bit size appropriate for the pipe material (3/8 inch is common for PVC pipes)

-Circular saw

-Heavy hammer or sledgehammer

-Pipe clamps

-Hinges or brackets (if replacing a section of pipe)

How Much Does It Generally Cost to Replace a Pipe?

Costs for relining vary depending on the type of pipe being replaced and the location but can be $5,000 to $50,000+.

Types of Relining Solutions Available

The most common reasons for relining are improper installation, inadequate maintenance, and water damage. Several relining solutions are available, each with its advantages and disadvantages.

The three most common types of relining solutions are:

– Epoxy Relining: This relining is best suited for areas where there is little opportunity for water damage and minimal exposure to the elements. Epoxy is a strong adhesive that holds the new lining in place and can resist cracking and distortion.

– Polymer Relining: Polymer relining is a more flexible solution that can withstand more exposure to the elements and water damage.


Relining can help solve common plumbing problems. If you have ever had water streaming down the side of your house or have had to call a plumber for one simple problem, you know that repairs can be costly and time-consuming. If your pipes are starting to give way or have developed some other type of issue, relining them may be the solution. Look for a reputed pipeline contractor to be clear about the cost and quality of the work to avoid a dent in your property.
