Bionax® SR PVCO Seismic Water Pipe

Bionax® SR combines the same strength, toughness and flexibility as standard Bionax pipe with the enhanced seismic-resistance benefits of an extended bell.

  • Compatible with North American pipes and fittings (CIOD)
  • Exceeds the Japanese seismic design standard by 70%
  • Corrosion resistance

The result is a municipal water transmission and distribution system which performs better than any pipe product available today. Bionax SR can improve absorption of lateral ground strain of seismic events and provides other performance benefits including product consistency, industry standard dimensions and corrosion-resistant attributes for North American jobsites.

Bionax is also offered in white for sewer pressure applications.
