Umbhobho wentsimbi we-ERW wenziwa "ngokumelana" okuphantsi okanye okuphindaphindiweyo. Ziityhubhu ezingqukuva ezidityaniswe kwiipleyiti zentsimbi ezinee-welds ezinde. Isetyenziselwa ukuthutha izinto eziphuma kumphunga-ulwelo ezifana neoyile kunye negesi yendalo, kwaye inokuhlangabezana neemfuno ezahlukeneyo zoxinzelelo oluphezulu noluphantsi. Okwangoku, ikwindawo ebalulekileyo kwicandelo leepayipi zothutho kwihlabathi liphela.
Ngexesha lokuwelda iityhubhu ze-ERW, ubushushu buyaveliswa xa umbane udlula kwiindawo zoqhagamshelwano zendawo eweldayo. Utshisa imiphetho yomibini yentsimbi ukuya kwinqanaba apho umphetho omnye unokwenza ikhonkco. Kwangaxeshanye, phantsi koxinzelelo oludibeneyo, imiphetho yetyhubhu engenanto iyanyibilika kwaye icinezelwe kunye.
Ngokwesiqhelo umbhobho we-ERW une-OD ephezulu ye-24” (609mm), ngobukhulu obukhulu umbhobho uya kwenziwa nge-SAW.
Kukho imibhobho emininzi enokwenziwa ngenkqubo ye-ERW. Ngezantsi sidwelisa imigangatho eqhelekileyo kwimibhobho.

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 kunye noxinzelelo oluphezulu. Kwiminyaka yakutshanje, ngophuhliso lwetekhnoloji ye-ERW, imibhobho yentsimbi ye-ERW emininzi isetyenziswa kwiindawo zeoyile negesi, kushishino lweemoto nakwezinye iindawo.
