Abstract

PURPOSE: To seal holes without difficulty and to secure the water-tightness of the sealed holes by a method wherein the end part of a perforated plastic pipe is cut off and worked into a perforated pipe having a nearly uniform thickness and the end part of this pipe is folded under heating so that the section of the pipe wall is encircled.
CONSTITUTION: The end part 10 of the plastic pipe 1 provided with a plurality of axial holes 11, 11... on the pipe wall is cut off and worked into a pipe 100 having a nearly uniform thickness and un holes excluding the inner layer part 101. Next, the end part 10 of the pipe is heated, this heated end part is forced into a metallic mold 2, the unperforated pipe part 100 is folded at a U-groove 21 of the end part of the metallic mold, this folded end is welded into the outer surface of the end part of the plastic pipe to encircle the section 12 of the pipe wall having perforated holes 11, 11.... Holes are sealed without difficulty and water-tightness can be secured.
