Abstract: An electrically grounded wear resistant liner is described that inserts into a conventional frac sand delivery conduit. The liner allows for conveyance of highly abrasive materials through the liner and conduit while electrically grounding potential static build up from within the liner. Sand, cement and other abrasive slurries may be conveyed through the liner. The wear resistant liner extends the amount of time that the conduit may be used to convey materials without downtime for replacement and repairs. The liner further provides a tri layer construction that includes a middle layer having a color notably different than the outer and inner layers, allowing a user in the fields to quickly determine that the conduit should be replaced.
