S355 JR Spiral Steel PipeMphamvu ndi Zosiyanasiyana
S355 JR chitoliro chachitsulo chozunguliraamapangidwa pogwiritsa ntchito zipangizo zamakono ndi zitsulo zamtengo wapatali kuti aziphatikiza mphamvu ndi kusinthasintha mu chinthu chimodzi.Mapaipiwa amapangidwa kuti azitha kupirira zovuta kwambiri, zomwe zimawapangitsa kukhala oyenera kugwiritsa ntchito mitundu yosiyanasiyana.Kaya amagwiritsidwa ntchito kunyamula madzi, mafuta kapena gasi, mapaipiwa amapereka ntchito yabwino komanso yolimba.
Mapangidwe amphamvu ndi kukhulupirika kwapangidwe
Chimodzi mwazinthu zodziwika bwino za chitoliro chachitsulo cha S355 JR ndikumanga kwake kolimba, komwe kumatsimikizira kukhulupirika kwadongosolo.Mapaipiwa amakhala ndi zozungulira zozungulira zomwe zimatsimikizira mphamvu yayikulu ndikuchepetsa chiopsezo cha kutayikira kapena kulephera.Mapangidwe apamwambawa amathandiza kuti mapaipi azitha kupirira katundu wolemetsa komanso nyengo yovuta, zomwe zimapangitsa kuti zikhale zoyenera kwa zomangamanga zofunika kwambiri monga milatho, tunnel ndi nyumba zapamwamba.

Kuyesedwa kwa Hydrostatic
Utali uliwonse wa chitoliro uyenera kuyesedwa ndi wopanga ku mphamvu ya hydrostatic yomwe idzapangitse mukhoma wa chitoliro kupsinjika kosachepera 60% ya mphamvu zokolola zosachepera zomwe zafotokozedwa kutentha.Kupanikizika kumatsimikiziridwa ndi equation yotsatirayi:
P=2St/D
Kusiyanasiyana Kololedwa Pakulemera ndi Makulidwe
Utali uliwonse wa chitoliro uyenera kuyezedwa padera ndipo kulemera kwake sikuyenera kupitirira 10% kuposa kapena 5.5% pansi pa kulemera kwake, kuwerengeredwa pogwiritsa ntchito kutalika kwake ndi kulemera kwake pa kutalika kwake.
Kuzungulira kwakunja sikuyenera kusiyanasiyana kupitilira ± 1% kuchokera m'mimba mwake mwadzina
Makulidwe a khoma nthawi iliyonse sayenera kupitirira 12.5% pansi pa makulidwe omwe atchulidwa
Kugonjetsedwa ndi dzimbiri ndi zinthu zachilengedwe
Pantchito iliyonse yomanga, kukhalitsa ndi kudalirika kwa zipangizo ndizofunika kwambiri.Mapaipi achitsulo a S355 JR amapambana pankhaniyi chifukwa amalimbana kwambiri ndi dzimbiri komanso zachilengedwe.Chitsulo chomwe chimagwiritsidwa ntchito popanga chimagwiritsidwa ntchito mwapadera kuti chiwonjezeke kukana kwake, kupanga mapaipi awa oyenera kuyika pamwamba ndi pansi.Kukaniza kumeneku sikungotsimikizira kukhulupirika kwa payipi, komanso kumachepetsa kwambiri ndalama zothandizira kukonza, ndikupangitsa kuti ikhale yotsika mtengo.
Wonjezerani kukhazikika komanso kuyanjana kwachilengedwe
Poyang'anizana ndi nkhawa zapadziko lonse zokhudzana ndi kusintha kwa nyengo komanso kuwonongeka kwa chilengedwe, makampani omangamanga akufunafuna njira zokhazikika.Chithunzi cha S355JRchitoliro chachitsulo chozungulirandi zobwezerezedwanso kwambiri ndipo zimathandiza kuti njira yokhazikikayi.Mapaipiwa akhoza kukonzedwanso ndi kugwiritsidwanso ntchito, kuchepetsa zinyalala ndi kusunga zachilengedwe.Kuphatikiza apo, moyo wawo wautali wautumiki umachepetsa kwambiri kufunika kosinthidwa, ndikuchepetsanso gawo lawo lonse la chilengedwe.
Tsatirani mfundo zabwino kwambiri
Chitoliro chachitsulo cha S355 JR chimapangidwa mosamala motsatira mfundo zokhwima.Izi zimatsimikizira kuti chitoliro chilichonse chimagwira ntchito mosasinthasintha ndikutsatira malamulo ofunikira otetezera.Kaya ndi ntchito zofunika kwambiri monga mapaipi amafuta ndi gasi kapena zomangamanga, mapaipiwa amapereka kudalirika, kudalirika komanso mtendere wamalingaliro kwa mainjiniya, makontrakitala ndi eni mapulojekiti.
Pomaliza
Mwachidule, chitoliro chachitsulo cha S355 JR chakhala gawo lofunikira la zomangamanga zamakono chifukwa champhamvu zake, kusinthasintha komanso magwiridwe antchito onse.Kapangidwe kake kolimba, kukana dzimbiri komanso kutsatira miyezo yapamwamba kumapangitsa kuti ikhale yabwino pantchito zomanga zosiyanasiyana.Kuphatikiza apo, kukhazikika kwawo komanso kuyanjana kwachilengedwe kumawonjezera phindu ndikuthandizira tsogolo lobiriwira.Pamene tikupitiriza kuchitira umboni kupita patsogolo kwa ntchito yomanga, zikuwonekeratu kuti chitoliro chachitsulo cha S355 JR chidzapitiriza kugwira ntchito yofunika kwambiri pakupanga dziko lomwe tikukhalamo.
