Cured-in-place pipe (CIPP) lining is a new trenchless pipe lining technology that offers significant advantages over traditional methods for the rehabilitation of pipelines. A wide variety of pipes can be lined via CIPP. Therefore, operators must consider their pipe system to determine which type is eligible for rehabilitation. Federal EC has compiled a list of the types of pipes that can be successfully rehabilitated via the CIPP pipe lining method.

Steel Pipes

Steel pipes are broken into two categories: cast iron, including ductile and brittle variants, and steel. Both types of pipe can be successfully rehabilitated using CIPP. The reason for such wide acceptance is that most steel pipes are already lined with a concrete counter-layer. Therefore, in most cases, only a minor amount of demolition work is required to prepare the pipe for the trenchless pipe lining process.

Concrete Pipes

Concrete pipes can be rehabilitated by replacing the existing liner using CIPP pipe lining. In most cases, it will be sufficient to remove the old liner and replace it with a new CIPP laid directly over the existing concrete pipe system. The process is referred to as ‘in-line trenchless rehabilitation.’ In some cases, the concrete pipe system might require the complete removal of the old concrete lining. This is usually necessary when the contractor responsible for your pipe rehabilitation in Atlanta, GA has chosen a new pipe diameter and initially used a thicker concrete lining.

Pipes Made From Composite Materials

The composite pipe consists of a combination of two or more materials, including metals and plastics. As it is made from multiple materials, underground utility construction projects that involve the use of composite pipes often require significant demolition work to be rehabilitated. However, the work is cut down considerably when CIPP is utilized.

HDPE Pipes

The thickest HDPE pipe rehabilitated using CIPP is 12 mm thick. This means that the only limitations are the thickness of the existing concrete and the thickness of the new composite liner. It can be successfully applied in trenchless or storm drain rehabilitation work when a new liner is directly laid on top of the existing pipe system.

Pipe rehabilitation is a complex process, so it can be beneficial to identify all the types of pipes that can be rehabilitated using CIPP and prepare a pipe rehabilitation strategy in advance. Call Federal EC for more information or for a consultation.
