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.Ngoku ikwindawo ephambili kwinkalo yezothuthoimibhobhoemhlabeni.
Niniukuwelda imibhobho ye-ERW, 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.ERW ASTM A53 iBanga A kunye neB carbon steel pipes (kunye negalvanized) ASTM A252imibhobho yentsimbi yekhabhoniImibhobho ye-ASTM A500 yemfumba ye-ASTM A134 kunye ne-ASTM A135 imibhobho yesakhiwo EN 10219 imibhobho S275, imibhobho ye-S355 Umbhobho weStainless Steel .API ERW umgca umbhobho API 5L B ukuya X70 PSL1 (PSL2 kufuneka HFW inkqubo) 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 ne-oyile kunye negesi yendalo, kwaye inokuhlangabezana neemfuno eziphantsi kunye noxinzelelo oluphezulu.Kwiminyaka yakutshanje, ngophuhliso lwetekhnoloji ye-ERW, ngakumbi nangakumbi imibhobho yentsimbi ye-ERW isetyenziswa kumasimi e-oyile negesi, kushishino lweemoto, njl.
