Linerputkista

Linerputkista, often translated as liner pipes or lining pipes, refers to a type of pipe used to create a new, inner lining within an existing pipe. This process is commonly employed in trenchless rehabilitation of underground pipelines, such as water mains, sewer lines, and gas pipes. The primary purpose of liner pipes is to restore the structural integrity and hydraulic capacity of deteriorated or damaged pipelines without the need for extensive excavation.

The installation of liner pipes typically involves inserting a new pipe material into the old, damaged pipe. This can be achieved through various methods, including pipe bursting, where the old pipe is fractured and simultaneously replaced by the new liner, or by pulling a new pipe through the existing one. Different materials are used for liner pipes, including high-density polyethylene (HDPE), polyvinyl chloride (PVC), and cured-in-place pipe (CIPP) materials, each offering specific advantages in terms of durability, flexibility, and resistance to corrosion.

The benefits of using liner pipes include significant cost savings compared to traditional open-cut replacement methods, reduced disruption to traffic and surrounding communities, and minimized environmental impact. Liner pipes can effectively seal leaks, prevent infiltration of groundwater, and improve flow characteristics by providing a smooth internal surface. This trenchless technology extends the lifespan of aging infrastructure and ensures reliable service delivery for essential utilities.
