RESIDUAL LIFE OF REPAIR WELDED JOINTS IN PIPELINES MADE OF 13HMF AFTER USE FOR THE DESIGN OPERATING TIME

Journal Title: Prace Instytutu Metalurgii Żelaza - Year 2018, Vol 70, Issue 3

Abstract

This paper presents the results of material tests of repair welded joints carried out for samples of materials taken from high pressure steam pipelines after over 200,000 operating hours in creep conditions, made of the 13HMF steel (14MoV6-3). The aim of the study was to assess the mechanical properties and changes in the structure of repair welded joints (new material + material after use), including the original material, heat affected zone and the weld, occurring as a result of the welding process and heat treatment after welding.
