ERW amapayipi ensimbizenziwa nge frequency low noma high frequency kagesi ukumelana "resistance". Amapayipi ayindilinga ashiselwe kusuka kumashidi ensimbi ane-longitudinal seams. Isetshenziselwa ukuthutha igesi nezinto eziwuketshezi ezifana nowoyela negesi yemvelo, futhi ingahlangabezana nezidingo ezihlukahlukene zokucindezela okuphezulu nokuphansi. Njengamanje inesikhundla esibalulekile endimeni yezokuthuthaamapayipiemhlabeni.
Niniukushisela amapayipi e-ERW, ukushisa kukhishwa lapho okwamanje kugeleza ezindaweni zokuthintana zendawo yokushisela. Ishisisa imiphetho emibili yensimbi kuze kube yilapho unqenqema olulodwa lungakha isibopho. Kulesi simo, ngaphansi kwengcindezi ehlangene, imiphetho yepayipi engenalutho iyancibilika futhi ikhishwe ndawonye.NgokuvamileAmapayipi e-ERWabe nobukhulu bangaphandle ububanzi obungama-intshi angu-24 (609 mm), amapayipi amakhulu enziwa kusetshenziswa i-SAW.
Maningi amapayipi angenziwa kusetshenziswa indlela ye-ERW. Ngezansi sibala izindinganiso ezivame kakhulu ekufakeni amapayipi.ERW ASTM A53 Ibanga A no-B amapayipi ensimbi ekhabhoni (kanye namagalani) ASTM A252carbon steel amapayipiI-ASTM A500 inqwaba yamapayipi ASTM A134 kanye ASTM A135 amapayipi esakhiwo EN 10219 amapayipi S275,S355 amapayipi.ERW Stainless Steel Pipe ASTM A269 Amazinga & Imininingwane ASTM A270 Stainless Steel Pipe ASTM A312 Ipayipi STM Ipayipi A312 Ipayipi lensimbi A312 Ipayipi lensimbi A312 I-Ferritic/Austenitic/Duplex Stainless Steel Pipe.API ERW line pipe API 5L B to X70 PSL1 (PSL2 kumele kube inqubo ye-HFW) API 5CT J55/K55,N80 casing kanye neshubhu.
Ukusetshenziswa kanye nokusetshenziswa kwepayipi lensimbi le-ERW: Ipayipi lensimbi i-ERW lisetshenziselwa ukuthutha igesi nezinto eziwuketshezi ezifana nowoyela negesi yemvelo, futhi lingahlangabezana nezidingo zomfutho ophansi nophezulu. Eminyakeni yamuva nje, ngokuthuthukiswa kobuchwepheshe be-ERW, amapayipi ensimbi amaningi e-ERW asetshenziswa ezindaweni zikawoyela negesi, embonini yezimoto, njll.
