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 replace compromised steel pipelines or rehabilitate them by installing a polyethylene pipeline liner or intervene with some other type of pipeline rehabilitation. A trenchless technology solution, such as polyethylene liner installation is usually preferred because excavation of the entire pipeline or wholesale replacement of the entire pipeline is prohibitively expensive and is usually inferior to simply lining the pipeline with polyethylene.
The most cost effective pipeline corrosion prevention or rehabilitation method is usually achieved through the installation of a high density polyethylene (HDPE) liner, preferably HEBNA HDRC. HEBNA HDRC is a premium HDPE specialized for the exacting demands of pipeline liners and meets and exceeds 4710/PE100+ standards. HEBNA HDRC reduces the risk of slow crack growth and rapid crack propagation, that occasionally beset 3708 liner-pipe used by our competitors. Readers are encouraged to read “PE100 Pipe Systems” by Heiner Brömstrup to learn more about the comparative properties of various grades of HDPE. The installation of an HDPE liner not only reduces pipeline corrosion and erosion, it also reduces pipeline friction, allowing for lower operating pressures, and reduced operating costs.
Only HEBNA can provide you with HEBNA HDRC liner pipe. You know you have HEBNA HDRC when it is printed on the liner pipe. We specialize in 3″ to 20″ pipe sizes, but our experienced technicians have installed liners as large as 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. HEBNA HDHT can be used for higher temperature environments.
