APPARATUS FOR SEALING PIPE

摘要

Disclosed is an apparatus for sealing pipes in order to stably operate a facility by preventing damage to a bellows cover due to thermal contraction and thermal expansion. An apparatus for sealing pipes prepared by the present invention seals a gap between a facility case of a waste heat recovery boiler and a pipe which penetrates the facility case. The apparatus for sealing pipes, where a bellows cover with a pleated side wall unit is connected with a sealing cover with an inside horizontal flow path unit, comprises a bellows pipe which covers a gap between a facility case and a pipe; a sealing plate which protrudes from and is combined with the outer circumference surface of the pipe in order to be placed in the horizontal flow path unit; and a sealing member including a vertical sealing unit, which seals a horizontal flow path space between the sealing cover inner wall and a sealing plate plane and between the sealing cover inner wall and the sealing plate bottom, and a horizontal sealing unit which the sealing cover inner wall and the sealing plate side surface.
