Umbhobho wentsimbi we-ERW wenziwe ngokumelana okuphantsi okanye okuphindaphindiweyo okuphezulu. Ziipayipi ezingqukuva ezidityanisiweyo kwiishiti zentsimbi ezinee-longitudinal seams. Isetyenziselwa ukuthutha izinto zomphunga wolwelo ezifana neoyile kunye negesi yendalo, kwaye inokuhlangabezana neemfuno ezahlukeneyo zoxinzelelo oluphezulu noluphantsi. Okwangoku ithatha indawo ephambili kwicandelo leepayipi zothutho kwihlabathi liphela.
Xa kudityaniswa imibhobho ye-ERW, ubushushu buyavela xa umbane udlula kwiindawo zoqhagamshelwano zendawo edibeneyo. Ufudumeza imiphetho yomibini yentsimbi ukuya kwinqanaba apho umphetho omnye unokwenza ijoyinti. Kwimeko enjalo, phantsi koxinzelelo oludibeneyo, imiphetho yombhobho ongenanto iyanyibilika kwaye icinezelwe.
Ngokwesiqhelo imibhobho ye-ERW inobubanzi obuphezulu obungaphandle obuyi-24 intshi (609 mm), ubukhulu obukhulu benziwa kwi-SAW.
Kukho imibhobho emininzi enokwenziwa kusetyenziswa indlela ye-ERW. Apha ngezantsi sidwelisa imigangatho eqhelekileyo kwimibhobho.

Umbhobho womgca we-API ERW API 5L B ukuya kwi-X70 PSL1 (PSL2 kufuneka ibe kwinkqubo ye-HFW) API 5CT J55/K55, N80 casing kunye netyhubhu
Ukusetyenziswa kunye nokusetyenziswa kombhobho wentsimbi ye-ERW: Umbhobho wentsimbi ye-ERW usetyenziselwa ukuthutha igesi kunye nezinto ezingamanzi ezifana neoyile negesi, kwaye unokuhlangabezana neemfuno zoxinzelelo oluphantsi noluphezulu. Kwiminyaka yakutshanje, ngophuhliso lwetekhnoloji ye-ERW, imibhobho yentsimbi ye-ERW emininzi isetyenziswa kwiindawo zeoyile negesi, kushishino lweemoto nakwezinye iindawo.
