Imibhobho yentsimbi ye-ERWzenziwe ngamaza aphantsi okanye amaza ombane aphezulu axhathisayo "ukumelana".Ziyimibhobho engqukuva edityaniswe kumaphepha entsimbi anemithungo emide.Isetyenziselwa ukuthutha igesi kunye nezinto ezingamanzi ezifana neoyile kunye negesi yendalo, kwaye inokuhlangabezana neemfuno ezahlukeneyo zoxinzelelo oluphezulu noluphantsi.Kungoku nje ikwindawo ephambili kwicandelo lemibhobho yezothutho ehlabathini.
Xa i-welding ERW imibhobho, ubushushu bukhutshwa xa ikhoyo iqukuqela kwiindawo zoqhagamshelwano zommandla we-welding.Itshisa imiphetho emibini yentsimbi ukuya kwindawo apho umgca omnye unokwenza ibhondi.Kule meko, phantsi koxinzelelo oludibeneyo, imiphetho yepayipi engenanto iyancibilika kwaye ikhutshwe kunye.
Ngokuqhelekileyoimibhobho ye-ERWinobukhulu obungaphandle bedayamitha yee-intshi ezingama-24 (609 mm), imibhobho emikhulu yenziwa kusetyenziswa i-SAW.
Mininzi imibhobho enokwenziwa kusetyenziswa indlela ye-ERW.Ngezantsi sidwelisa imigangatho eqhelekileyo kwimibhobho yamanzi.
I-ERW ASTM A53 yeBanga A kunye nemibhobho yentsimbi yekhabhoni (kunye negalvanized)I-ASTM A252imibhobho yentsimbi yekhabhoniImibhobho ye-ASTM A500I-ASTM A134 kunye ne-ASTM A135 imibhobho yesakhiwoEN 10219 imibhobho S275, S355 imibhobho.

API ERW umbhobho womgca API 5L B ukuya X70 PSL1 (PSL2 kufuneka HFW inkqubo) API 5CT J55/K55, N80i-casing kunye ne-tubing.
Ukusetyenziswa kunye nokusetyenziswa kwepayipi yensimbi ye-ERW: Ipayipi yensimbi ye-ERW isetyenziselwa ukuthutha igesi kunye nezinto ezimanzi ezifana neoli kunye negesi yendalo, kwaye inokuhlangabezana neemfuno eziphantsi kunye noxinzelelo oluphezulu.Kwiminyaka yakutshanje, ngophuhliso lwetekhnoloji ye-ERW, ngakumbi nangakumbi imibhobho yentsimbi ye-ERW isetyenziswa kwiindawo zeoyile nerhasi, kushishino lweemoto, njl.
