RTP offers many benefits over steel throughout its lifespan starting with a 20% cost savings during the installation process due to reduced time and labor.* It requires less maintenance and monitoring while also providing improved flow characteristics over rigid steel pipe.   To meet these needs, pipe manufacturers bring in reinforcements: Avient’s thermoplastic composites.   The corrosion resistance improvements provided by Polystrand-reinforced pipe offer significant savings in monitoring, inspection, and maintenance costs compared to traditional steel.
