Chitoliro cholumikizidwa mozungulira chimapangidwa popinda chingwe chachitsulo cha chitsulo chopangidwa ndi mpweya wochepa kapena chitsulo chopangidwa ndi mpweya wochepa kukhala chitoliro chopanda kanthu malinga ndi ngodya inayake ya helix (yotchedwa ngodya yopangira), kenako nkulumikiza zolumikizira za chitoliro. Chimatha kupanga mapaipi achitsulo akuluakulu kuchokera ku zingwe zopapatiza zachitsulo.

(1) mapaipi achitsulo okhala ndi mainchesi osiyanasiyana amatha kupangidwa pogwiritsa ntchito chitsulo chozungulira chokhala ndi m'lifupi womwewo, makamaka mapaipi achitsulo okhala ndi mainchesi akulu amatha kupangidwa ndi chitsulo chopapatiza chozungulira.
(2) Pansi pa kupanikizika komweko, mphamvu ya weld yozungulira ndi yaying'ono kuposa ya weld yowongoka, yomwe ndi 75% ~ 90% ya mphamvu ya chitoliro chowongoka, kotero imatha kupirira kupsinjika kwakukulu. Poyerekeza ndi chitoliro chowongoka chowongoka chokhala ndi mainchesi ofanana akunja, makulidwe a khoma amatha kuchepetsedwa ndi 10% ~ 25% pansi pa kupsinjika komweko.
(3) Miyeso yake ndi yolondola, nthawi zambiri kulekerera kwa m'mimba mwake kumakhala kochepera 0.12%, kupotoka kumakhala kochepera 1/2000, ndipo kupendekera kwake kumakhala kochepera 1%, kotero njira zoyezera kukula ndi kuwongola nthawi zambiri sizingatchulidwe.
(4) Kupanga kosalekeza n'kotheka. M'malingaliro, mapaipi achitsulo aatali kwambiri amatha kupangidwa. Kutayika kwa mutu ndi mchira wodulidwa ndi kochepa, ndipo kuchuluka kwa kugwiritsa ntchito chitsulo kumatha kuwonjezeredwa ndi 6% ~ 8%. (5) Poyerekeza ndi chitoliro chowongoka cholumikizidwa, chimasinthasintha pogwira ntchito, ndipo chimakhala chosavuta kusintha mitundu ndikusintha.
(6) Kulemera kochepa kwa zida ndi ndalama zochepa zoyambira. Zitha kupangidwa kukhala mayunitsi oyenda ngati thireyila kuti apange mapaipi olumikizidwa mwachindunji pamalo omangira mapaipi.
(7) N'zosavuta kuzindikira makina ndi zochita zokha.
Chitoliro cholumikizidwa ndi spiral chimagwiritsidwa ntchito makamaka mu uinjiniya wa madzi apampopi, makampani opanga mafuta, makampani opanga mankhwala, makampani opanga magetsi, ulimi wothirira ndi zomangamanga m'mizinda ku China. Chimagwiritsidwa ntchito poyendetsa madzi: kupereka madzi ndi ngalande. Poyendetsa gasi: gasi wa malasha, nthunzi ndi gasi wamafuta osungunuka. Chimagwiritsidwa ntchito ngati kapangidwe kake: chimagwiritsidwa ntchito ngati chitoliro choyendetsera milu ndi mlatho; mapaipi a doko, misewu ndi nyumba zomangira, ndi zina zotero.
Kugwiritsa ntchito
Monga makampani otsogola mumakampani opanga zinthu zachitsulo ku China, malonda achitsulo ndi zinthu zamtundu wa "Zana la bizinesi yabwino", makampani ogulitsa zitsulo ku China, "Mabizinesi 100 apamwamba kwambiri ku Shanghai". Shanghai Zhanzhi industry Group Co., Ltd., (yofupikitsidwa ku Zhanzhi Group) imatenga "Umphumphu, Kuchita Zinthu Mwanzeru, Kupanga Zinthu Mwatsopano, Kupambana" ngati mfundo yokhayo yogwirira ntchito, nthawi zonse imapitiliza kuyika zofuna za makasitomala pamalo oyamba.
