LSAW (Longitudinal Submerged Arc Welded) umuyoboro wibyuma nubwoko bwicyuma gisudira cyakozwe hakoreshejwe uburyo bwo gusudira arc bwarohamye.
| Hanze ya Diameter | 325-2020MM |
| Umubyimba | 7.0-80.0MM (kwihanganira +/- 10-12%) |
| Uburebure | 6M-12M |
| Bisanzwe | API 5L, ASTM A553, ASTM A252 |
| Icyiciro | Icyiciro B, x42, x52 |
| Umuyoboro urangira | Beveled endwith cyangwa idafite umuyoboro wanyuma urinda ibyuma |
| Ubuso bw'imiyoboro | Umukara Kamere Yashushanyije Umukara 3PE Yashizweho |
API 5L:Ibipimo ngenderwaho byashyizweho n’ikigo cy’Abanyamerika gishinzwe peteroli kandi kigaragaza ibisabwa mu gukora imiyoboro y’umurongo ikoreshwa mu kugeza peteroli, gaze, n’ibindi bicuruzwa bishingiye kuri peteroli. Kubahiriza API 5L byemeza ko umuyoboro wa LSAW wujuje ibyangombwa nkenerwa kugirango ukoreshwe mu nganda za peteroli na gaze.
ASTM A53:ASTM A53 nigisobanuro gisanzwe cyumuyoboro, ibyuma, umukara nubushyuhe-bwuzuye, zinc-yuzuye, gusudira, hamwe. Kubahiriza ASTM A53 byemeza ko umuyoboro wa LSAW wujuje ibyangombwa bisabwa kugirango ukoreshwe mu mashini n’umuvuduko, kimwe no gukoreshwa muri rusange.
ASTM A252:ibisobanuro bisanzwe kubirundo byicyuma gisudira kandi kidafite icyerekezo. Ku bijyanye na LSAW (Longitudinal Submerged Arc Welded) imiyoboro y'ibyuma, kubahiriza ASTM A252 ni ngombwa cyane cyane mubisabwa birimo ibirundo by'ibyuma bikoreshwa mu bwubatsi no mu mishinga yo gutera inkunga. ASTM A252 yerekana ibisabwa bya tekiniki kubirundo byibyuma, harimo ibipimo, imiterere yubukanishi, hamwe nuburyo bwo gupima.
Imiyoboro y'icyuma ya LSAW yubahiriza ASTM A252 yagenewe kubahiriza ibisabwa byihariye kugirango ikoreshwe mu gutwara indege, nko kubaka umusingi, inyubako zo mu nyanja, kubaka ikiraro, n'indi mishinga y'ubwubatsi. Kubahiriza ASTM A252 byemeza ko imiyoboro yicyuma ya LSAW yujuje ubuziranenge bukenewe, imikorere, numutekano kugirango bigenewe gukoreshwa mubisabwa.
