SAW (Longitudinal Submerged Arc Welded) Imiyoboro iratandukanye nubundi bwoko bwimiyoboro isudira ikoreshwa muri sisitemu yo kuvoma.Zikoreshwa cyane mu miyoboro yohereza peteroli na gaze,nibikorwa byubaka nko kubaka ibiraro na tunel.
Ku bijyanye n’ibipimo, imiyoboro ya LSAW ihuye n’ibipimo byashyizweho n’ikigo cy’Abanyamerika gishinzwe peteroli (API), Umuryango mpuzamahanga ushinzwe ubuziranenge (ISO), n’umunyamerika
Sosiyete y'Abashinzwe Imashini (ASME).Ibipimo ngenderwaho bisobanura ibisobanuro ku bipimo, imiterere yimiti, imiterere yubukanishi, hamwe nibisabwa byo gupima imiyoboro ya LSAW.
Imiyoboro ya LSAWbaraboneka mubyiciro bitandukanye nka ASTM A671, ASTM A672, ASTM A525,BS EN10210, BS EN10219, na API 5L Gr.B. Guhitamo amanota biterwa no gusabaibisabwa nkumuvuduko, ubushyuhe, nubwoko bwamazi atwarwa.
Imikoreshereze y'imiyoboro ya LSAW iratandukanye, kandi ikoreshwa cyane mumirongo yohereza peteroli na gaze, imiyoboro y'amazi, hamwe nuburyo bukoreshwa nko kubaka ibiraro na tunel.Iyi miyoboro irahitamohejuru yindi miyoboro isudira nkuko itanga uburinganire bwiza, imbaraga ndende, kandi biramba.Imiyoboro ya LSAW irashobora gukorwa mubunini n'uburebure, bigatuma biba byiza gukoreshwa mumiyoboro miremire.
Mu gusoza, imiyoboro ya LSAW igira uruhare runini mu kohereza peteroli na gaze no kuyikoresha.Bihuye nibipimo bikaze, biza mubyiciro bitandukanye, kandi biramba kandi byizewe.
