... test conditions and definition of boundary conditions for HIC resistance of these steels with regard to solution pH and H₂S partial pressure. Therefore HIC tests were performed on HIC susceptible submerged arc welded (SAW) large-diameter pipe API 5L grade X65 linepipe steel under different...

...Abstract For evaluation of performance of submerged arc welded (SAW) large-diameter pipes of grades X65, X70, X80 and X100 hydrogen-induced stress corrosion cracking (HSCC) tests to NACE TM0177-96 Method A in test solution A and constant-extension-rate tests (CERT) have been performed in ASTM...

...Sour service SSC test four-point-bend test low alloy steel large-diameter pipe SAW longitudinal weld INTRODUCTION Abstract For investigation of the resistance of submerged arc welded (SAW) large-diameter pipes for application in sour service, a new full-size four-point-bend test method has...

... For investigation of the corrosion behavior of low alloy steels for large-diameter pipes for application in CO₂ containing aqueous media, two alloy variations were produced as laboratory heats of 100 kg each, which contained 0.78 and 0.96 % Cr, respectively. Plates were rolled with a thickness of 20 mm...
