Ipayipi lensimbi le-ERW lakhiwa “ukumelana” nefrikhwensi ephansi noma “ukumelana” nefrikhwensi ephezulu. Amashubhu ayindilinga ashiselwe ngamapuleti ensimbi anamashisela obude. Lisetshenziselwa ukuthutha izinto eziwuketshezi oluwuketshezi olunjengowoyela negesi yemvelo, futhi lingahlangabezana nezidingo ezihlukahlukene zokucindezela okuphezulu nokuphansi. Okwamanje, lisesikhundleni esibalulekile emkhakheni wamapayipi okuthutha emhlabeni.
Phakathi ne-ERW tube welding, ukushisa kukhiqizwa lapho amandla kagesi egeleza ezindaweni zokuthintana zendawo eshiselwe.Ishisa imiphetho yomibili yensimbi kuze kube yilapho unqenqema olulodwa lungakha isibopho.Ngesikhathi esifanayo, ngaphansi kwengcindezi ehlangene, imiphetho ye-tube engenalutho iyancibilika futhi ihlanganiswe ndawonye.
Ngokuvamile ipayipi le-ERW line-OD ephezulu engu-24” (609mm), kosayizi abakhulu ipayipi lizokwenziwa nge-SAW.
Kunamapayipi amaningi angenziwa ngenqubo ye-ERW.Ngezansi sibala izindinganiso ezivame kakhulu ekufakeni amapayipi.

Ukusetshenziswa kanye nokusetshenziswa kwepayipi lensimbi le-ERW: Ipayipi lensimbi le-ERW lisetshenziselwa ukuthutha igesi nezinto eziwuketshezi ezifana nowoyela negesi, futhi lingahlangabezana nezidingo zokucindezela okuphansi nokucindezela okukhulu.Eminyakeni yamuva nje, ngokuthuthukiswa kobuchwepheshe be-ERW, amapayipi ensimbi e-ERW ayanda asetshenziswa ezindaweni zikawoyela negesi, embonini yezimoto nakweminye imikhakha.
