Creep properties of ASTM A335 P92 pipe parent material and erection welded joint simulation: effect of 1 or 3 PWHT
ABSTRACT Field experience with new generation CSEF steels, such as grade 92, is still quite limited. The Italian Creep Group (GdL) launched a testing effort, to characterise creep performance of a pipe weld joint, representative of true current manufacturing and on-site assembly conditions. A P92 pipe from standard production was supplied by Tenaris and welded by AnsaldoEnergia according to standard procedures. Istituto Italiano della Saldatura qualified the welding procedure. Parent material and cross-weld (after one PWHT) creep and tensile behaviour was investigated according to ECCC requirements. Results were presented at ECCC2017 conference.
期刊介绍：
Materials at High Temperatures welcomes contributions relating to high temperature applications in the energy generation, aerospace, chemical and process industries. The effects of high temperatures and extreme environments on the corrosion and oxidation, fatigue, creep, strength and wear of metallic alloys, ceramics, intermetallics, and refractory and composite materials relative to these industries are covered.
Papers on the modelling of behaviour and life prediction are also welcome, provided these are validated by experimental data and explicitly linked to actual or potential applications. Contributions addressing the needs of designers and engineers (e.g. standards and codes of practice) relative to the areas of interest of this journal also fall within the scope. The term ''high temperatures'' refers to the subsequent temperatures of application and not, for example, to those of processing itself.
Materials at High Temperatures publishes regular thematic issues on topics of current interest. Proposals for issues are welcomed; please contact one of the Editors with details.
