API 5L Welded Steel Pipe Kaʻina Hana Hana
ʻAno 1. Welded Spiral: ʻO nā paipu kila wiliwili ʻiahana ʻia e ka wiliwili ʻana i kahi kaula kila, e hana ana i kahi hili helical. Hiki i kēia kaʻina hana ke hana i nā paipu anawaena nui a ʻoi aku ka maikaʻi o ke kumukūʻai no kekahi mau noi.
Ka uhi a me ka lapaʻau ʻana:No ka hoʻoikaika ʻana i ka pale ʻana i ka corrosion a me ka lōʻihi, hiki i kēia mau paipu ke komo i nā kaʻina hana hoʻopalapala like ʻole, e like me ka fusion bonded epoxy (FBE) a i ʻole nā uhi polyethylene (3LPE) ʻekolu-layer.
'Ano 2. Uila Kū'ē Kū'ē (RW):Hoʻohana ʻia nā ʻaoʻao o ke kaula kila me ka hoʻohana ʻana i ka pale uila. A laila hoʻohana ʻia ke kaomi no ka hoʻopili ʻana i nā ʻaoʻao, e hana ana i kahi weld paʻa me ka ʻole o ka mea hoʻopihapiha.
ʻAno 3.ʻO ka welding longitudinal:
ʻO Submerged Arc Welding (SAW): Hoʻopili pū ʻia nā ʻaoʻao o ka paipu i hana ʻia me ka hoʻohana ʻana i ke kaʻina hana kuʻi ʻana o ke arc submerged, e pili ana i ka hoʻohana ʻana i kahi arc uila a me kahi flux granular e hana i kahi weld kiʻekiʻe a ikaika.
Hoʻopaʻa ʻia ʻo Double Submerged Arc Welding (DSAW): No nā paipu mānoanoa, hoʻopaʻa ʻia nā hili o loko a me waho, e hōʻoia ana i ke komo piha ʻana a me ka ikaika.
