Imibhobho yentsimbi ye-ERWZenziwe ngokumelana nombane okuphantsi okanye okune-frequency ephezulu. Ziipayipi ezingqukuva ezidityaniswe ngeeshiti 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 lothutho.imibhobhoemhlabeni.
Niniukuwelda imibhobho ye-ERW, ubushushu buyakhululwa xa umsinga udlula kwiindawo zoqhagamshelwano zommandla wokuwelda. 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. Ngezantsi sidwelisa imigangatho eqhelekileyo kwimibhobho ye-ERW ASTM A53 Iipayipi zentsimbi yekhabhoni zeBanga A kunye ne-B (kunye ne-galvanized) ASTM A252imibhobho yentsimbi yekhabhoniIipayipi ze-ASTM A500 ze-ASTM A134 kunye ne-ASTM A135 zesakhiwo seepayipi ze-EN 10219 iipayipi ze-S275,S355. I-ERW Stainless Steel Pipe ASTM A269 Imigangatho kunye neenkcukacha ze-ASTM A270 Stainless Steel Pipe ASTM A312 Plumbing Pipe ASTM A790 Stainless Steel Pipe Ferritic/Austenitic/Duplex Stainless Steel Pipe.API Ipayipi yomgca we-ERW API 5L B ukuya kwi-X70 PSL1 (PSL2 mayibe yinkqubo ye-HFW) API 5CT J55/K55,N80 casing kunye ne-tubing.
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.
