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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
