Method of repairing a tubesheet having delaminated sections

摘要

A method of repairing a tubesheet (10) having delaminated sections, wherein each said section includes tube apertures (12) formed therethrough, said method comprising:
inserting a flow through plug (28) within at least one of the tube apertures wherein said flow through plug has a longitudinal axis and an aperture along said axis and said flow through plug is tapered; and
applying a force to said flow through (28) plug sufficient to create a press fit between said flow through plug and each section of the tubesheet, thereby relaminating each of the sections of the tubesheet.
