Abstract

A steam generator heating tube repair sleeve has an encircling flange, conical region, and a straight region. The encircling flange merges into a conical region that tapers on the outside in the direction of the other sleeve end and which is adjoined to the straight region. A steam generator heating tube repair method is used to repair a steam generator heating tube that is installed in a steam generator having a defective tube end. The method includes conical milling out of the defective tube end, inserting a steam generator heating tube repair sleeve into the conically milled-out defective tube end, rolling in the steam generator heating tube repair sleeve, and welding the flange region.
