Abstract
A method for creating a coating onto an inner diameter of conduit, whereby an injection nozzle is moved in a forward direction until its tip is aligned with the end of the conduit. Slurry is pumped from a reservoir into the injection nozzle and then is discharged through the tip of the injection nozzle. The slurry flows, distributes and spreads onto the surface of the conduit. The conduit is rotated and the nozzle is retracted as slurry continues to discharge from the nozzle to coat the remainder of the conduit.
