发明名称 A METHOD FOR LINING THE INTERNAL SURFACE OF A PIPE
摘要 There is provided a method for lining the internal surface of a pipe having a first open end and a second open end. Said method comprises the steps of introducing a predetermined amount of a resin into the pipe through the first open end thereof, causing the introduced resin to move through the pipe toward the second open end thereof, so as to form a resin lining layer on the internal surface of the pipe, blowing into the pipe a predetermined amount of flake material and causing the flake material to adhere to the surface of the resin lining layer in the pipe, inserting into the pipe a ball-like pig having a predetermined diameter such that an even resin lining layer having a desired uniform thickness may be formed on the internal surface of the pipe, and causing the inserted ball-like pig to move through the pipe along the entire length thereof, thereby embeding the above flake material into the resin lining layer, and forming on the pipe internal surface an even resin lining layer having a desired uniform thickness.
