Pipe slip-lining is a specialized trenchless method of rehabilitating damaged or deteriorating pipelines using a new pipe, called the liner, which is inserted into the existing pipeline. Here’s a general overview of the process:
PREPARATION:
The existing pipeline is first inspected to assess the extent of the damage and determine whether it is suitable for slip-lining. The pipeline is then cleaned and prepared by removing any debris, roots, or other obstructions.
FABRICATION:
The liner is typically fabricated offsite and can be made from a variety of materials, including high-density polyethene (HDPE), polyvinyl chloride (PVC), or steel. The liner is customized to the size and shape of the existing pipeline.
INSTALLATION:
The liner is inserted into the existing pipeline using a variety of methods, such as pulling, pushing, or inversion. As the liner is inserted, it is expanded to fit tightly against the inside of the existing pipeline, forming a continuous pipe within a pipe.
SEALING:
Once the liner is in place, the ends are sealed to prevent infiltration and exfiltration of water or other materials. This can be done using a variety of methods, such as compression seals, gaskets, or grout.
INSPECTION:
Once the liner has been installed and sealed, it is inspected by our team of experts to ensure that it meets the required standards for strength and durability. This may involve the use of visual or non-destructive testing methods to detect any potential issues with the liner. Slip-lining offers a number of benefits over traditional pipeline repair methods, including reduced disruption to the surrounding area, faster installation times, and improved resistance to corrosion and wear. It is also a cost-effective solution for rehabilitating damaged or deteriorating pipelines, as it eliminates the need for costly excavation and replacement. Additionally, slip-lining can be customized to fit a wide range of pipeline sizes and shapes.
