Water Pipes

PE 100 HDPE

KUPP’s HDPE water pipes are manufactured from high-density polyethylene (HDPE) PE100, renowned for its excellent physical and chemical properties. They are resistant to corrosion and electrochemical degradation. The addition of carbon black further enhances UV and weather resistance. The HDPE raw material’s inherent hygiene is well-established, being frequently used for food containers and cutting boards. Consequently, KUPP’s HDPE pipes are ideally suited for a wide spectrum of applications—from potable water and beverages to piping in water-treatment facilities.

Plant Piping

PE 100 (PERC)

PE 100 RC maintains the excellent Rapid Crack Propagation (RCP) performance of conventional PE 100 while significantly enhancing Slow Crack Growth (SCG) resistance. This mitigates long-term slow-crack failure caused by scratches during installation, thereby extending the pipe’s service life and reinforcing its abrasion resistance. It is ideally suited as an insertion pipe for trenchless installation methods, which are recently gaining popularity. Furthermore, its outstanding chemical resistance has resulted in increased utilization in demanding environments, such as semiconductor facilities and chemical wastewater piping.
