Mafotokozedwe Akatundu
Electrical Resistance Welding, ERW Steel Pipes amapangidwa ndi kuzizira kupanga koyilo yachitsulo kukhala yozungulira yozungulira.Mapaipi a ERW adachitidwa ndi ma frequency otsika a AC kuti atenthetse m'mbali poyamba.Tsopano mkulu pafupipafupi AC m'malo otsika pafupipafupi ndondomeko panopa kutulutsa apamwamba weld.
Mapaipi achitsulo a ERW amapangidwa ndi ma frequency otsika kapena kukana kwambiri kwamagetsi.Mapaipi achitsulo a ERW ndi machubu ozungulira omwe amawotcherera kuchokera ku mbale zachitsulo zokhala ndi ma weld aatali.Amagwiritsidwa ntchito kunyamula zinthu za gasi ndi zamadzimadzi monga mafuta ndi gasi, ndipo amatha kukwaniritsa zofunikira zosiyanasiyana zamphamvu komanso zotsika.
ERW mipope zitsulo chimagwiritsidwa ntchito mipanda, chitoliro mzere, scaffolding etc.
Mapaipi achitsulo a ERW amapangidwa mosiyanasiyana, makulidwe a khoma, kumaliza ndi magiredi.
Ntchito zazikulu
● Mapaipi a ERW omwe amagwiritsidwa ntchito m'mapaipi a Madzi
● Ulimi ndi ulimi wothirira (Mapaipi amadzi, mipope yamadzi m'mafakitale, mapaipi a zomera, zitsime zakuya zapaipi & mapaipi osungira madzi, mapaipi a seweji)
● Mizere ya mapaipi a gasi
● LPG ndi mizere ina yopanda poizoni

Kupaka & Kutumiza
Njira yopakira mapaipi achitsulo imaphatikizapo kuyeretsa, kuyika magulu, kukulunga, kumanga, kusunga, kulemba zilembo, palletizing (ngati kuli kofunikira), kuyika zida, stowing, kusindikiza, mayendedwe, ndi kumasula.Mitundu yosiyanasiyana ya mapaipi achitsulo ndi zoyikira ndi njira zosiyanasiyana zolongedza.Njira yonseyi imatsimikizira kuti mapaipi achitsulo amatumizidwa ndikufika komwe akupita ali bwino, okonzeka kugwiritsidwa ntchito.
Kugwiritsa Ntchito & Kugwiritsa Ntchito
Mapaipi achitsulo amagwira ntchito ngati msana wa uinjiniya wamakono wamafakitale ndi wamba, kuthandizira ntchito zingapo zomwe zimathandizira chitukuko chamagulu ndi chuma padziko lonse lapansi.
Mapaipi achitsulo ndi zomangira zomwe ife Womic Zitsulo zomwe zimagwiritsidwa ntchito kwambiri popanga mafuta, gasi, mapaipi amafuta & madzi, kunyanja / kumtunda, ntchito zomanga madoko & zomanga, kukhetsa, Zitsulo zomanga, kuyika milu ndi ntchito zomanga mlatho, komanso machubu achitsulo olondola a conveyor roller. kupanga, etc...
