Mu gawo lomwe likusintha nthawi zonse la uinjiniya wa zomangamanga, kuphatikiza ukadaulo wamakono kwasintha kwambiri, makamaka pankhani yokonza mapaipi. Pamene mizinda ikukula ndipo kufunika kwa nyumba zolimba kukuwonjezeka, kusankha zinthu zoyenera ndikofunikira kwambiri kuti ntchito zomanga zipambane komanso zikhale zokhalitsa. Pakati pa zosankha zosiyanasiyana zomwe zilipo, chitoliro chozungulira cha arc (SSAW pipe) chakhala chisankho chomwe chimakondedwa, ndi zabwino zake zambiri zomwe zikukonzanso mawonekedwe a chitukuko cha zomangamanga.
Kufunika kwakuyika mapaipiPa ntchito yomanga sitingathe kuipitirira muyeso. Ndi maziko a nyumba zambiri, zomwe zimathandiza kuti pakhale kupirira mavuto a chilengedwe komanso zofunikira pa kunyamula katundu. M'zaka zaposachedwapa, kuyambitsidwa kwa njira zamakono zopangira zinthu kwapangitsa kuti pakhale chitoliro cha SSAW, chomwe chimapangidwa pogwiritsa ntchito njira yapadera yolumikizirana ndi waya. Njirayi sikuti imangowonjezera mphamvu ndi kulimba kwa chitolirocho, komanso imalola kusinthasintha kwakukulu pakupanga ndi kugwiritsa ntchito.
Chimodzi mwa ubwino waukulu wa chitoliro cha SSAW ndi kuthekera kwake kupirira zovuta zambiri, zomwe zimapangitsa kuti chikhale choyenera kugwiritsidwa ntchito m'njira zosiyanasiyana. Kapangidwe kake kozungulira kamapereka weld yopitilira, kuchepetsa kwambiri chiopsezo cha kulephera pansi pa katundu wolemera. Izi ndizofunikira kwambiri pamapulojekiti a zomangamanga komwe chitetezo ndi kudalirika ndizofunikira kwambiri. Kuphatikiza apo, chitoliro cha SSAW chimadziwika chifukwa cha kukana dzimbiri, komwe kumawonjezera moyo wa ntchito ya kapangidwe kake, zomwe pamapeto pake zimapangitsa kuti ndalama zisungidwe kwa nthawi yayitali.
Fakitaleyi, yomwe ili ku Cangzhou, m'chigawo cha Hebei, yakhala patsogolo popanga mapaipi apamwamba kwambiri opangidwa ndi spiral submerged arc weld kuyambira pomwe idakhazikitsidwa mu 1993. Fakitaleyi ili ndi malo okwana 350,000 sikweya mita, ili ndi katundu wokwana RMB 680 miliyoni, ndipo imagwiritsa ntchito antchito aluso pafupifupi 680. Zomangamanga zolimbazi zimathandiza kampaniyo kukwaniritsa zosowa zomwe zikukula zamakampani omanga nyumba pomwe ikusunga miyezo yokhwima yowongolera khalidwe.
Pamene ukadaulo wamakono ukupitirira kupita patsogolo, njira yopangira zinthuChitoliro cha SSAWkwakhala kopita patsogolo kwambiri. Zatsopano monga kuwotcherera kodziyimira pawokha komanso njira zowunikira zapamwamba zimaonetsetsa kuti chitoliro chilichonse chikukwaniritsa miyezo yapamwamba kwambiri yaubwino ndi magwiridwe antchito. Kudzipereka kumeneku pakuchita bwino sikungowonjezera mbiri ya kampaniyo, komanso kumabweretsa chidaliro kwa mainjiniya ndi makontrakitala omwe amadalira zipangizozi pa ntchito zawo.
Kuphatikiza apo, momwe zipangizo zomangira zimakhudzira chilengedwe ndi nkhani yomwe ikukulirakulira masiku ano. Chitoliro cha SSAW chimapangidwa poganizira za kukhazikika kwa zinthu, pogwiritsa ntchito njira zosagwiritsa ntchito mphamvu zambiri komanso zinthu zomwe zingabwezeretsedwenso. Izi zikugwirizana ndi kukakamiza kwapadziko lonse lapansi kuti pakhale njira zomangira zobiriwira, zomwe zimapangitsa kuti ikhale njira yokongola yogwiritsira ntchito mapulojekiti osawononga chilengedwe.
Pomaliza, kuphatikiza ukadaulo wamakono m'mapaipi, makamaka pogwiritsa ntchito mapaipi a SSAW, kukusintha ukadaulo wa zomangamanga. Mapaipi awa amapereka zabwino monga mphamvu, kulimba, komanso kukhazikika, zomwe zimapangitsa kuti akhale chisankho chabwino kwambiri kwa mainjiniya ndi makontrakitala. Pamene makampaniwa akupitilizabe kusintha, n'zoonekeratu kuti tsogolo la chitukuko cha zomangamanga lidzakhudzidwa kwambiri ndi zatsopano muukadaulo wa mapaipi. Ndi makampani ngati Cangzhou omwe akutsogolera, mwayi wopanga nyumba zolimba komanso zokhazikika ndi wopanda malire.
