Mu dongosolo la mapaipi, chigongono ndi chitoliro choyenera chomwe chimasintha mayendedwe a payipi.Malinga ndi ngodyayo, pali zigongono zitatu zomwe zimagwiritsidwa ntchito nthawi zambiri za 45 ° ndi 90 ° 180 °, ndipo zigongono zina zachilendo monga 60 ° zimaphatikizidwanso malinga ndi zosowa zamainjiniya.Zida za m'gongono ndi chitsulo choponyedwa, chitsulo chosapanga dzimbiri, chitsulo cha aloyi, chitsulo chosungunuka, chitsulo cha carbon, zitsulo zopanda chitsulo ndi mapulasitiki.Njira kugwirizana ndi chitoliro ndi: kuwotcherera mwachindunji (njira wamba) flange kugwirizana, otentha Sungunulani kugwirizana, electrofusion kugwirizana, ulusi kugwirizana ndi kugwirizana zitsulo, etc. Malinga ndi ndondomeko kupanga, zikhoza kugawidwa mu: kuwotcherera chigongono, kuponda chigongono, kukankha chigongono, kuponyera chigongono, matako kuwotcherera chigongono, etc. Mayina ena: 90 digiri chigongono, kumanja ngodya bend, chikondi ndi kupinda, etc.
Chigongono chosasunthika ndi mtundu wa zida zapaipi zomwe zimagwiritsidwa ntchito potembenuza mapaipi.Pakati pa zida zonse zapaipi zomwe zimagwiritsidwa ntchito pamapaipi, gawoli ndi pafupifupi 80%.Nthawi zambiri, njira zopangira zosiyana zimasankhidwa pazigono zokhala ndi zida zosiyanasiyana komanso makulidwe a khoma.Panopa.Zomwe zimagwiritsidwa ntchito popanga zigongono zopanda msoko pazopanga zopanga zimaphatikizapo kukankhira kotentha, kupondaponda, kutulutsa, etc.
Zigongono zopanda msoko zimatchedwanso ziboliboli zopanda chitsulo.Chifukwa cha njira zosiyanasiyana zopangira, zopangira zopanda msoko zimagawidwa m'zigongono zotentha (zotuluka) zopanda msoko ndi zozizira zokoka (zogudubuzika) zopanda msoko..Machubu ozizira (okulungidwa) amagawidwa m'mitundu iwiri: machubu ozungulira ndi machubu ooneka ngati apadera.
Zopangira zokutira zopanda msokonezo ndizopanda machubu ozungulira.Zolemba za chubu zozungulira zimadulidwa ndi makina odulira mu billet ndi kutalika kwa mita imodzi ndikutumizidwa ku ng'anjo kuti itenthedwe kudzera pa lamba wotumizira.Billet amadyetsedwa mu ng'anjo ndikutenthedwa kutentha pafupifupi madigiri 1200 Celsius.Mafutawa ndi hydrogen qi kapena acetylene.Kuwongolera kutentha mu ng'anjo ndi nkhani yaikulu.Pambuyo pa billet yozungulira kunja kwa ng'anjo, iyenera kupyozedwa ndi makina opopera.Nthawi zambiri, makina oboola ofala kwambiri ndi makina oboola a tapered.Makina oboola amtundu uwu ali ndi magwiridwe antchito apamwamba kwambiri, mtundu wabwino wazinthu, kukulitsa kwakukulu koboola m'mimba mwake, ndipo amatha kuvala zopangira zitoliro zosiyanasiyana.Pambuyo kuboola, chozungulira chubu billet chimapingidwa, mosalekeza-kugudubuza kapena kufinyidwa ndi mipukutu itatu imodzi pambuyo pa inzake.Mukafinya, chotsani chubu ndikuwongolera.Makina ojambulira amagwiritsa ntchito chobowola chozungulira kuti chizungulire mwachangu muzitsulo zopanda kanthu kuti zibowole mabowo kuti apange zomangira zitoliro.
