ERW (Electric Resistance Welded) mapaipiamapangidwa kuchokera ku ma koyilo opindika otentha polumikizana ndi malekezero awiri a koyiloyo. Kuthamanga kwapakati pafupipafupi kumadutsa pamakoyilo okulungidwa pogwiritsa ntchito ma electrode amkuwa.
Kuthamanga kotsutsana kwa magetsi pakati pa ma kondakitala kumapangitsa kutentha kwakukulu kumangoyang'ana m'mphepete, kupanga kukana. Pamene kutentha kwina kukufika, kukakamiza kumagwiritsidwa ntchito, kuchititsa kuti seams agwirizane.
Makhalidwe a ERW mapaipi:
● Msoko wowotcherera wautali.
● Amapangidwa podutsa magetsi othamanga kwambiri kudzera muzitsulo zachitsulo ndikusakaniza mapeto ake pansi pa kupanikizika kwakukulu.
● Kunja kumayambira ½ mpaka 24 mainchesi.
● Makulidwe a khoma amasiyana kuchokera ku 1.65 mpaka 20mm.
● Utali wamba ndi 3 mpaka 12 m, koma utali wautali umapezeka mukaupempha.
●Zitha kukhala zomveka bwino, zokongoletsedwa, kapena zopindika monga momwe kasitomala wafotokozera.
● Mapaipi a ERW otchulidwa pansi pa ASTM A53 amapanga maziko a mapaipi ambiri omwe amagwiritsidwa ntchito mumafuta, gasi, kapena zakumwa za nthunzi.
Njira Yopangira Mapaipi a ERW:
●Makoyilo achitsulo ndi zinthu zoyambira popangira mapaipi a ERW.
● Zingwe zachitsulo zimadulidwa m'lifupi mwake ndi kukula kwake asanazipereke ku mphero.
● Zitsulo zachitsulo zimatsukidwa pakhomo la chigayo cha ERW ndipo amadutsa pansi pa mpheroyo kuti apange mawonekedwe ngati chubu ndi msoko wosatsekedwa wa longitudinal.
●Njira zosiyanasiyana monga kuwotcherera msoko, kuwotcherera kwa flash, ndi kuwotcherera kwa resistion projection amagwiritsidwa ntchito.
● Magetsi othamanga kwambiri, otsika kwambiri amadutsa maelekitirodi amkuwa akumangirira paipi yachitsulo yosamalizidwa kuti itenthetse mbali zotseguka.
●Kuwotcherera kwa ng'anjo kumagwiritsidwa ntchito kwambiri chifukwa sikufuna zida zowotchera.
● Mafomu otulutsira arc pakati pa m'mphepete mwake, ndipo akafika kutentha koyenera, seams amapanikizidwa palimodzi kuti awotcherera mankhwala.
● Mikanda yowotcherera nthawi zina amadulidwa pogwiritsa ntchito zida za carbide, ndipo malo owotcherera amaloledwa kuzizirira.
●Machubu oziziritsa amatha kulowa mumpukutu kuti awonetsetse kuti m'mimba mwake ikugwirizana ndi zomwe mukufuna.
Kugwiritsa Ntchito Mapaipi a ERW:
●Mapaipi a ERW amagwiritsidwa ntchito kwambiri ngati mapaipi onyamula mafuta, gasi, ndi zinthu zina. Amakhala ndi mainchesi apamwamba kuposa mapaipi opanda msoko ndipo amatha kukumana ndi zofunikira zapamwamba komanso zotsika, zomwe zimawapangitsa kukhala ofunikira ngati mapaipi oyendera.
● Mapaipi a ERW, makamaka a specification API 5CT, amagwiritsidwa ntchito mu casing ndi chubu
● Mapaipi a ERW amatha kugwiritsidwa ntchito ngati machubu opangira magetsi amphepo
● Mapaipi a ERW amagwiritsidwa ntchito popanga zinthu monga manja onyamula, kukonza makina, makina opangira, ndi zina zambiri
● Mapaipi a ERW amagwiritsa ntchito potumiza gasi, mapaipi amadzimadzi amagetsi amagetsi, ndi zina zambiri.
● Amagwiritsidwanso ntchito pomanga, mapaipi apansi panthaka, mayendedwe amadzi apansi panthaka, komanso mayendedwe amadzi otentha.
