Abstract

Two bent pipe sections of the fuel oil system of a heavy-duty gas turbine engine had to be disassembled due to leakage. One of the two specimens received by the laboratory of the engine manufacturer featured a sub-standard weld repair performed by customer personnel. A metallurgical failure investigation was ordered to determine the root cause of the leakage and to verify the results of a laboratory investigation already performed by a third party at the customer's request. The repair-welded bent pipe section failed due to halide-induced pitting corrosion that propagated through-wall in a transgranular stress corrosion cracking (SCC) mode.

Kurzfassung

Zwei gebogene Rohrabschnitte des Heizölsystems einer Industrie-Gasturbine mussten aufgrund einer Leckage demontiert werden. Eine der beiden Proben, die im Labor des Maschinenherstellers eingegangen sind, wies eine durch Mitarbeiter des Kunden durchgeführte minderwertige Reparaturschweißung auf. Eine metallurgische Fehleruntersuchung wurde angeordnet, um die Ursache der Leckage zu bestimmen und die Ergebnisse einer auf Anfrage des Kunden bereits durch Dritte durchgeführte Laboruntersuchung zu überprüfen. Der gebogene Rohrabschnitt mit der Reparaturschweißung versagte aufgrund von halogenidinduzierter Lochkorrosion, die sich durch die Rohrwand als transkristalline Spannungsrisskorrosion (SpRK) ausbreitete.
