Mapaipi achitsulo ozungulira amagwiritsidwa ntchito makamaka pantchito zoperekera madzi, mafakitale a petrochemical, makampani opanga mankhwala, mafakitale amagetsi, ulimi wothirira, komanso zomangamanga zamatawuni. Mapaipi achitsulo ozungulira ali m'gulu lazinthu 20 zomwe zapangidwa m'dziko langa. Kwa kayendedwe ka madzi: madzi ndi ngalande. Zoyendera gasi: gasi wamalasha, nthunzi, gasi wamafuta amafuta. Zolinga zomangika: kuyika mapaipi, milatho; mipope kwa madoko, misewu, nyumba zomangira, etc. Spiral zitsulo chitoliro ndi kozungulira msoko zitsulo chitoliro welded ndi basi awiri-waya mbali ziwiri kumizidwa arc kuwotcherera ndondomeko ntchito Mzere zitsulo koyilo mbale monga zopangira, zonse kutentha extrusion akamaumba. Chitoliro chachitsulo chozungulira chimadyetsa chingwecho mu chitoliro chowotcherera. Pambuyo pokulungidwa ndi zodzigudubuza zingapo, mzerewo umakulungidwa pang'onopang'ono kupanga chubu chozungulira chopanda kanthu ndi mpata wotseguka. Kusintha kuchepetsa kuchuluka kwa wodzigudubuza extrusion kulamulira kuwotcherera kusiyana pakati 1-3mm, ndi kupanga malekezero onse a kuwotcherera olowa kuwotcherera.

Kusiyana pakati pa ozungulira zitsulo chitoliro ndi mwatsatanetsatane zitsulo chitoliro
Mipope yachitsulo yozungulira imatha kugawidwa m'magulu awiri molingana ndi njira zopangira: spiral ndi seamed. Mipope yachitsulo yosoka imatchedwa mipope yachitsulo yowongoka. Mapaipi achitsulo ozungulira amatha kugawidwa m'mapaipi osasunthika otentha otenthedwa, mapaipi okokedwa ozizira, mapaipi achitsulo olondola, mapaipi owonjezera ndi kutentha, mapaipi ozungulira ozizira, ndi mapaipi otuluka molingana ndi njira zopangira. Mapaipi achitsulo ozungulira amapangidwa ndi chitsulo chamtengo wapatali cha carbon kapena alloy steel ndipo amatha kugawidwa m'magulu otentha komanso ozizira (wokoka). Mbali yaikulu ya ozungulira zitsulo chitoliro ndi kuti alibe kuwotcherera seams ndipo akhoza kupirira mavuto aakulu.

Zogulitsa zimatha kukhala zaukali kwambiri ngati zida zotayidwa kapena zozizira. Mapaipi achitsulo amagawidwa m'mapaipi otenthetsera ng'anjo, ma welded (kukana welded) mapaipi, ndi ma welded arc welded mapaipi chifukwa cha njira zawo zowotcherera. Chifukwa cha njira zawo zowotcherera zosiyanasiyana, amagawidwa kukhala mipope yowongoka ya msoko ndi mipope yowotcherera yozungulira. Iwo amagawidwa mu mipope wozungulira welded chifukwa mapeto akalumikidzidwa ndi zooneka welded mapaipi ndi wapadera woboola pakati (mabwalo, lathyathyathya, etc.) welded mapaipi.

Mapaipi achitsulo amapangidwa ndi mbale zachitsulo zokulungidwa mu mawonekedwe a tubular ndi kuwotcherera ndi matako kapena seams ozungulira. Pankhani ya njira kupanga, iwo anawagawa mipope zitsulo okhotakhota kwa otsika-anzanu mayendedwe madzimadzi, ozungulira msoko magetsi welded mipope zitsulo, molunjika koyilo welded mipope zitsulo, mipope magetsi welded, etc. Spiral zitsulo mipope angagwiritsidwe ntchito mapaipi madzi pneumatic ndi mapaipi gasi m'mafakitale osiyanasiyana. Kuwotcherera angagwiritsidwe ntchito mipope madzi, mapaipi mpweya, Kutentha mapaipi, mipope magetsi, etc.

Mipope yachitsulo yolondola ndi zinthu zomwe zawonekera m'zaka zaposachedwa. Iwo makamaka ndi kulolerana okhwima ndi roughness pa dzenje lamkati ndi miyeso yakunja khoma. Chitoliro chachitsulo cholondola ndi chitoliro chachitsulo chapamwamba kwambiri chomwe chakonzedwa ndi kujambula kozizira kapena kugudubuza kotentha. Chifukwa palibe wosanjikiza wa okusayidi pamakoma amkati ndi akunja a mipope yabwino yachitsulo, palibe kutayikira pansi pa kupsinjika kwakukulu, kulondola kwambiri, kuwala kwakukulu, palibe mapindikidwe opindika ozizira, palibe ming'alu yowotcha ndi kuwotcha, etc., imagwiritsidwa ntchito kwambiri kupanga zinthu zopangidwa ndi pneumatic kapena hydraulic, monga masilindala kapena silinda ya Mafuta.
