Amashubhu ashiselwe ukumelana nogesi (ERW) akhiqizwa ngokubanda okwenza umucu wensimbi oyisicaba ube yishubhu eliyindilinga futhi awudlulise ochungechungeni lwamaroli akhayo ukuze kutholwe ukushisela okude.Imiphetho emibili ibe isishisiswe kanyekanye nge-high-frequency current futhi iyaminyana ukuze yakhe ibhondi.Ayikho insimbi yokugcwalisa edingekayo ekushiseleleni ama-longitudinal ERW.
Azikho izinsimbi ezihlanganisiwe ezisetshenziswa ngesikhathi sokukhiqiza.Lokhu kusho ukuthi ipayipi liqine ngokwedlulele futhi lihlala isikhathi eside.
I-weld seam ayikwazi ukubonakala noma ukuzwa.Lona umehluko omkhulu uma ubheka inqubo yokushisela i-arc engaphansi kwamanzi ephindwe kabili, eyenza ubuhlalu obucacile obubunjiwe obungase budinge ukuqedwa.
Ngokuthuthuka kwamaza kagesi anemvamisa ephezulu yokushisela, inqubo ilula kakhulu futhi iphephile.
Amapayipi ensimbi e-ERW akhiqizwa yi-low-frequency noma high-frequency resistance "resistance".Amapayipi ayindilinga ashiselwe ngamapuleti ensimbi anamashisela e-longitudinal.Isetshenziselwa ukuthutha uwoyela, igesi yemvelo nezinye izinto eziwuketshezi oluwuketshezi, futhi ingahlangabezana nezidingo ezihlukahlukene zokucindezela okuphezulu nokuphansi.Njengamanje, inesikhundla esibalulekile emkhakheni wamapayipi ezokuthutha emhlabeni.
Ngesikhathi sokushisela ipayipi le-ERW, ukushisa kukhiqizwa lapho okwamanje kugeleza endaweni yokuxhumana yendawo yokushisela.Ishisisa imiphetho emibili yensimbi kuze kube yilapho unqenqema olulodwa lungakha isibopho.Ngesikhathi esifanayo, ngaphansi kwesenzo sokucindezela okuhlangene, imiphetho ye-tube engenalutho iyancibilika futhi ihlanganise ndawonye.
Ngokuvamile ipayipi le-ERW eliphezulu OD lingu-24" (609mm), ipayipi lezilinganiso ezinkulu lizokhiqizwa nge-SAW.
