Abstract

See full text

A method of lining an interior wall of a pipe is provided. Casting equipment such as a spin caster is used to centrifugally cast material onto the interior wall while the pipe is partially filled with liquid so as to form a coating on the wall above the liquid. In some embodiments the method further comprises diverting liquid from the pipe after the casting step, and then lining the wall of the pipe below the coating with material to form a continuous lining on the wall.
