Ulwazi oluNxulumeneyo lwe-ERW

        Imibhobho yentsimbi ye-ERWZenziwe ngokumelana nombane okuphantsi okanye okune-frequency ephezulu "nokuxhathisa". Ziipayipi ezingqukuva ezidityanisiweyo kwiishiti zentsimbi ezinee-longitudinal seams. Zisetyenziselwa ukuthutha igesi kunye nezinto ezingamanzi ezifana neoyile kunye negesi yendalo, kwaye zinokuhlangabezana neemfuno ezahlukeneyo zoxinzelelo oluphezulu noluphantsi. Okwangoku ithatha indawo ephambili kwicandelo leepayipi zothutho kwihlabathi liphela.
Xa kudityaniswa imibhobho ye-ERW, ubushushu buyakhululwa xa umsinga udlula kwiindawo zoqhagamshelwano zommandla wokudityaniswa. Utshisa imiphetho emibini yentsimbi ukuya kwinqanaba apho umphetho omnye unokwenza ikhonkco. Kwimeko enjalo, phantsi koxinzelelo oludibeneyo, imiphetho yombhobho ongenanto iyanyibilika kwaye ikhutshwe kunye.

NgokwesiqheloImibhobho ye-ERWinobubanzi obuphezulu bangaphandle obuyi-24 intshi (609 mm), imibhobho emikhulu yenziwa kusetyenziswa i-SAW.
Kukho imibhobho emininzi enokwenziwa kusetyenziswa indlela ye-ERW. Apha ngezantsi sidwelisa imigangatho eqhelekileyo kwimibhobho.
Imibhobho yentsimbi yekhabhoni ye-ERW ASTM A53 yeBanga A kunye ne-B (kunye ne-galvanized) imibhobho yentsimbi yekhabhoni ye-ASTM A252 imibhobho yenqwaba ye-ASTM A500 imibhobho yesakhiwo ye-ASTM A134 kunye ne-ASTM A135Imibhobho ye-EN 10219 S275, iipayipi ze-S355.

I-API ERW line pipe API 5L B ukuya kwi-X70 PSL1 (PSL2 mayibe yinkqubo ye-HFW) API 5CT J55/K55, N80ikheyiji kunye neetyhubhu.
Ukusetyenziswa kunye nokusetyenziswa kombhobho wentsimbi ye-ERW: Umbhobho wentsimbi ye-ERW usetyenziselwa ukuthutha igesi kunye nezinto ezingamanzi ezifana neoyile kunye negesi yendalo, kwaye unokuhlangabezana neemfuno zoxinzelelo oluphantsi noluphezulu. Kwiminyaka yakutshanje, ngophuhliso lwetekhnoloji ye-ERW, imibhobho yentsimbi ye-ERW emininzi isetyenziswa kwiindawo zeoyile kunye negesi, kushishino lweemoto, njl.njl.
