Chitoliro chachitsulo cha ERW chimapangidwa ndi "kukana" kochepa kapena kotsika kwambiri. Ndi mapaipi ozungulira olumikizidwa kuchokera ku mapepala achitsulo okhala ndi mipata yayitali. Chimagwiritsidwa ntchito kunyamula zinthu zamadzimadzi monga mafuta ndi gasi wachilengedwe, ndipo chimatha kukwaniritsa zofunikira zosiyanasiyana za kuthamanga kwambiri komanso kotsika. Pakadali pano chili ndi udindo wofunikira kwambiri pa ntchito za mapaipi oyendera padziko lonse lapansi.
Polumikiza mapaipi a ERW, kutentha kumachitika pamene magetsi akuyenda pamwamba pa malo olumikizirana a malo olumikizirana. Amatenthetsa m'mbali zonse ziwiri za chitsulo mpaka kufika pomwe m'mphepete umodzi ungapange cholumikizira. Pankhaniyi, pansi pa kupanikizika kophatikizana, m'mbali mwa chitoliro chopanda kanthu zimasungunuka ndikukakamizidwa.
Kawirikawiri mapaipi a ERW amakhala ndi mainchesi 609 (24 mm) m'mimba mwake, ndipo kukula kwakukulu kumapangidwa pa SAW.
Pali mapaipi ambiri omwe angapangidwe pogwiritsa ntchito njira ya ERW. Pansipa tilemba miyezo yodziwika bwino ya mapaipi.

Kugwiritsa ntchito ndi kugwiritsa ntchito chitoliro chachitsulo cha ERW: Chitoliro chachitsulo cha ERW chimagwiritsidwa ntchito ponyamula mpweya ndi zinthu zamadzimadzi monga mafuta ndi gasi, ndipo chimatha kukwaniritsa zofunikira zochepa komanso zapamwamba. M'zaka zaposachedwa, ndi chitukuko cha ukadaulo wa ERW, mapaipi ambiri achitsulo a ERW akugwiritsidwa ntchito m'magawo amafuta ndi gasi, makampani opanga magalimoto ndi madera ena.
