Umbhobho wentsimbi we-ERW wenziwa nge-frequency ephantsi okanye i-high frequency resistance "resistance". Ziyimibhobho engqukuva edityaniswe kumaphepha entsimbi anemithungo emide. Isetyenziselwa ukuthutha izinto zolwelo-umphunga 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 buveliswa xa umbane wombane uhamba kwindawo yokudibanisa yendawo edibeneyo. Itshisa imiphetho yomibini yentsimbi ukuya kwindawo apho umgca omnye unokwenza udibaniso. Kule meko, phantsi koxinzelelo oludibeneyo, imida yepayipi engenanto iyancibilika kwaye ixinzelelwe.
Ngokuqhelekileyo imibhobho ye-ERW inobukhulu obungaphandle bedayamitha yee-intshi ezingama-24 (609 mm), iisayizi ezinkulu zenziwe kwi-SAW.
Mininzi imibhobho enokwenziwa kusetyenziswa indlela ye-ERW. Ngezantsi sidwelisa imigangatho eqhelekileyo kwimibhobho yamanzi.
I-ERW ASTM A53 iBanga A kunye neBanga B (kunye negalvanized) ASTM A252 carbon steel pipe ASTM A500 imbhobho yombhobho ASTM A134 kunye ASTM A135 umbhobho wesakhiwo EN 10219 S275, S355 umbhobho wepayipi
I-ERW iStainless Steel Pipe / ASTM A269 iMigangatho yeMibhobho kunye neNkcazelo ye-ASTM A270 iPipe yentsimbi eNgatyiwayo ye-ASTM A312 Umbhobho ococekileyo we-ASTM A790 umbhobho wentsimbi eNgatyiwayo
Umbhobho womgca API ERW API 5L B ukuya X70 PSL1 (PSL2 kufuneka ibe kwinkqubo HFW) API 5CT J55/K55, N80 casing kunye netyhubhu
Ukusetyenziswa kunye nokusetyenziswa kwepayipi yensimbi ye-ERW: Ipayipi yensimbi ye-ERW isetyenziselwa ukuthutha igesi kunye nezinto ezingamanzi ezifana neoli kunye negesi, kwaye inokuhlangabezana neemfuno eziphantsi kunye noxinzelelo oluphezulu. Kwiminyaka yakutshanje, kunye nophuhliso lweteknoloji ye-ERW, ngakumbi nangakumbi imibhobho yentsimbi ye-ERW isetyenziswa kumasimi e-oyile negesi, kushishino lweemoto kunye namanye amacandelo.
