Hydroprocessing reactors are made of heavy wall Cr-Mo steels with stainless steel cladding and installed in the most of oil refineries in the world during past half century. After long time operation, they found several material degradation and/or damages due to high pressure and high temperature hydrogen services. This paper presents typical remediation method of flaws in stainless steel cladding of reactors including flaw sizing, FFS assessment and repair procedures.
