Structure of the material of homogeneous butt-welded joint components of the main primary steam pipeline made of 14MoV6-3 steel after approximately 200,000 h service under creep conditions parent
(PDF) Mechanical properties of cr-mo and cr-mo-v low-alloy Purpose:The purpose of this paper was to evaluate mechanical properties of 13CrMo4-5 and 14MoV6-3 steel homogeneous circumferential welded joints after long-term service under creep conditions
fective weld size for flare groove welds when filled flush to the surface of a round bar, a 90° bend in a formed sec-tion, or a rectangular tube shall be as shown in Table 2.1, except as permitted by 4.10.5. 2.3.4 Complete Joint Penetration Groove Welds 188.8.131.52 Weld Size. The weld size of a complete joint penetration groove weld shall be the
Creep Characteristics of Engineering Materials IntechOpenThe assessment of suitability for further service of the basic material and circumferential welded joints of primary steam pipelines made of 14MoV6-3 steel was made based on the determined characteristics of their mechanical properties and structure. The tests were carried out on materials after service significantly exceeding the design time and 200,000 h.
Fatigue Analysis Of Butt Welded Joint Using LEFM involve welded components, which have to be designed to avoid fatigue failure. In the present work, an attempt has been made to investigate on the fatigue performance of butt weld joint of Grade 2 Steel material. 2. Literature Survey Fatigue analysis of butt weld joints

Investigation of welded structures on mechanical Jun 01, 2015 · The effects of welded structures on pullout force and fatigue life were investigated in this paper. The results of both the pullout test and low cycle fatigue test show that the joints of the extension welded structure have best performance, which could be a reference for design and manufacture of welded tube-to-tubesheet joint.
