API 5L GrB Dijametru Kbir Pajp ta 'l-Azzar tal-Karbonju Baxx huwa manifatturat minn azzar tal-karbonju ta'-kwalità għolja jew billetti ta' azzar-ligati baxxi permezz ta' proċessi ta' tpinġija-sħun jew kiesaħ-biex jiffurmaw struttura tubulari mingħajr saldatura. Il-kompożizzjoni kimika tagħha għandha tissodisfa b'mod strett ir-rekwiżiti bħal C Inqas minn jew ugwali għal 0.28%, Mn Inqas minn jew ugwali għal 1.20%, b'saħħa ta' rendiment minimu ta' 241 MPa u saħħa tat-tensjoni li tvarja bejn 413-517 MPa. Dan id-disinn tal-kompożizzjoni jiżgura s-saħħa filwaqt li jżomm il-weldjabbiltà billi jikkontrolla l-ekwivalenti tal-karbonju (tipikament Inqas minn jew ugwali għal 0.43%).
GNEE Group jimpjega linja ta' produzzjoni ta' proċess sħiħ-li tinkludi billetta tonda ta' ikkastjar kontinwu, tisħin tal-forn taċ-ċirku, titqib, rolling kontinwu, qies, tkessiħ, iddrittar, u ttestjar mhux distruttiv. Il-proċess tal-irrumblar bis-sħana-irfina l-istruttura tal-qamħ, u jsaħħaħ it-toughness tat-temperatura-baxxa tal-pajp.
Meta mqabbla ma 'pajpijiet ta' l-azzar iwweldjati, l-istruttura mingħajr saldatura telimina l-punt dgħajjef potenzjali tal-weldjaturi, li toffri affidabilità superjuri f'ambjenti ta '-pressjoni għolja (pressjoni tax-xogħol komuni: 4-8 MPa) u midja korrużiva. Kwalità-għoljaAPI 5L GrB pajpijiet juru wkoll reżistenza għall-ikkrekkjar tal-korrużjoni tal-istress tas-sulfid (SSCC)., li hija kritika għall-iżvilupp tal-qasam tal-gass qares.
