Our seamless PVC FRP dual laminate uses only virgin polyvinyl chloride (PVC) and is chemically inert to a broad range of commercial chemicals.

Bonding of the PVC liner to the FRP structure results in a chemical linking of the structure to the liner, eliminating air gaps and the possibility of condensation, a common problem in lined steel pipe. Since these gases/ liquids are not trapped between our PVC liner and vinyl ester structure, weep holes and internal corrosion can be avoided. Choosing RPS dual laminate means longer life and lower lifecycle costs.
