ERW zitsulo chitoliro amapangidwa ndi otsika pafupipafupi kapena mkulu pafupipafupi kukana "kukana". Ndi mapaipi ozungulira omwe amawotcherera kuchokera ku mapepala achitsulo okhala ndi seams longitudinal. Amagwiritsidwa ntchito kunyamula zinthu za nthunzi zamadzimadzi monga mafuta ndi gasi, ndipo amatha kukwaniritsa zofunikira zosiyanasiyana zamphamvu komanso zotsika. Pakali pano ili ndi malo ofunikira kwambiri pantchito zamapaipi amayendedwe padziko lonse lapansi.
Powotcherera mapaipi a ERW, kutentha kumapangidwa pamene mphamvu yamagetsi imayenda m'malo olumikizana ndi malo owotcherera. Imatenthetsa mbali zonse ziwiri zachitsulo mpaka m'mphepete umodzi ukhoza kupanga mgwirizano. Pankhaniyi, pansi pa kukakamiza kophatikizana, m'mphepete mwa chitoliro chopanda kanthu chimasungunuka ndi kupanikizidwa.
Nthawi zambiri mapaipi a ERW amakhala ndi mainchesi 24 (609 mm), kukula kwake kwakukulu kumapangidwa ku SAW.
Pali mapaipi ambiri omwe angapangidwe pogwiritsa ntchito njira ya ERW. M'munsimu ife lembani mfundo zofala kwambiri mu mapaipi.
