Imiyoboro ya ERWbikozwe numuyoboro muke cyangwa mwinshi wumuriro wamashanyarazi "resistance".Ni imiyoboro izengurutswe mu mpapuro z'icyuma zifite uburebure.Ikoreshwa mu gutwara gaze nibintu byamazi nka peteroli na gaze gasanzwe, kandi irashobora kuzuza ibisabwa bitandukanye byumuvuduko mwinshi kandi muto.Kugeza ubu ifite umwanya wingenzi mubijyanye no gutwara abantu ku isi.
Iyo gusudira imiyoboro ya ERW, ubushyuhe burarekurwa mugihe umuyaga unyuze hejuru yimiterere ya zone yo gusudira.Ashyushya impande ebyiri zicyuma kugeza aho impande imwe ishobora gukora umurunga.Muri iki gihe, munsi yigitutu gihuriweho, impande zumuyoboro zirimo gushonga no gusohokera hamwe.
MubisanzweImiyoboro ya ERWufite diameter ntarengwa yo hanze ya santimetero 24 (609 mm), imiyoboro minini ikorwa ukoresheje SAW.
Hariho imiyoboro myinshi ishobora gukorwa hakoreshejwe uburyo bwa ERW.Hano hepfo turondora ibipimo bisanzwe mubisanzwe.
ERW ASTM A53 Icyiciro cya A na B Icyuma cya karubone (na galvanised) ASTM A252 imiyoboro yicyuma cya karubone ASTM A500 imiyoboro yikirundo ASTM A134 na ASTM A135 imiyoboro yubatswe;EN 10219 imiyoboro S275, Imiyoboro ya S355.

Umuyoboro wa API ERW API 5L B kugeza X70 PSL1 (PSL2 igomba kuba inzira ya HFW) API 5CT J55 / K55, N80ikariso.
Gukoresha no gukoresha umuyoboro wibyuma bya ERW: Umuyoboro wicyuma wa ERW ukoreshwa mugutwara gaze nibintu byamazi nka peteroli na gaze gasanzwe, kandi birashobora kuzuza ibisabwa bike kandi byumuvuduko mwinshi.Mu myaka yashize, hamwe niterambere ryikoranabuhanga rya ERW, imiyoboro myinshi yicyuma ya ERW ikoreshwa mumasoko ya peteroli na gaze, inganda zitwara ibinyabiziga, nibindi.
