HDPE Lined Steel Pipe
About Rendifield HDPE Lined Steel Pipe
HDPE (High-Density Polyethylene) lined steel pipe combines the strength and rigidity of steel with the corrosion resistance and chemical inertness of HDPE. This innovative piping system is highly durable and versatile, making it ideal for industries such as mining, water treatment, and chemical processing.
Using Sure-Line trenchless technology, overland steel pipelines can be lined with HDPE to extend the lifespan of existing pipelines or enhance the wear and chemical resistance of new ones. RENDIFIELD MINING AND INDUSTRIAL PIPING SOLUTIONS offers continuous lined pipes that reduce costs by minimising pipe spool sections, fewer flanges, and potential leak points.
The HDPE liner provides exceptional resistance to corrosion and wear, making it perfect for applications such as slurry transport, mining tailings, oil and gas, sewer systems, and bulk water supply. This combination ensures long-lasting performance and reliability in demanding environments.
