Polyethylene Pipe Solution - Liner Pipeline Rehabilitation, Coating and Corrosion

Pipelines are constantly degraded over time by chemical and biological processes, and physical abrasion. To prevent pipeline leakage and costly environmental damage, pipeline owners and operators must decide whether to replace corroded steel pipelines or rehabilitate them by installing a tight fitting high density polyethylene pipeline liner. A loose liner, or slip-liner as they are sometimes called, is another option, albeit inferior, because it compromises pipeline capacity,  and requires the liner to have much greater wall thicknesses to safely operate without the strength of the steel.

HEBNA's HDPE pipeline liner installation method is a trenchless technology solution, and is generally the preferred remediation technology for two reasons. Firstly, it is the most cost effective long-term solution. A pipeline liner installation is likely to protect your pipeline for decades, not years.  Secondly, an HDPE pipeline liner installation minimizes environmental impact  because your existing pipeline will remain in-situ and contribute to the strength of the new hybrid dual-contaniment pipeline system. 

The best value among pipeline corrosion prevension and rehabilitation methods is usually, installation of a tight fitting HDPE liner, preferably a PE100+ pipeline system.  For detailed engineering details regarding PE100, please refer to the book "PE 100 Pipe Systems" by Heiner Bomstrup.

Not only does the installation of an HDPE liner reduce pipeline corrosion and erosion, it also reduces pipeline friction, allowing for lower operating pressures, and reduced operating costs.

HEBNA utilizes HDPE liners ranging in size from 2" to 36" in diameter.

HDPE liners are suitable for the transportation of the following: crude oil, potable and non-potable water, effluent, sewer water, slurry, wet gas, and C0₂.

HDPE liners can be used for most fluids and gases up to 82°C.
