ʻO ke kaʻina hana o ka Longitudinal Submerged-arc Welded (LSAW) Pipe penei:
ʻO ka hoʻāʻo ʻana o ka pā kani kani → ka wili ʻana i ka ʻaoʻao → ka hoʻopololei ʻana → ka hana ʻana → Pre-weld → Ke kuʻi ʻana i loko → Ke kuʻi ʻana o waho → Ka nānā ʻana i ke kani kani → Ka nānā ʻana i ka X-ray → Hoʻonui → ka hoʻāʻo hydraulic → l.Chamfering → Nānā Ultrasonic → Nānā X-ray → nānā i nā ʻāpana magnetic ma ka hopena paipu
Hana ʻia: LSAW(JCOE) Paipu kila
Nui : OD: 406~1500mm WT: 6~40mm
Papa: CB60, CB65, CC60, CC65, etc.
Ka lōʻihi: 12M a i ʻole ka lōʻihi i kuhikuhi ʻia e like me ka makemake.
