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 ibambe isikhundla esibalulekile emkhakheni wamapayipi ezokuthutha emhlabeni.
Uma ushisela 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 kumapayipi.
