Nkhani - Ductile Iron Pipe: Mainstay of Modern Pipeline Systems

Ductile Iron Pipe, amapangidwa ndi chitsulo chosungunula monga maziko. Asanathire, magnesium kapena osowa lapansi magnesiamu ndi zina spheroidizing zitsulo amawonjezeredwa chitsulo chosungunula kuti spheroidize graphite, ndiyeno chitoliro amapangidwa mwa mndandanda wa njira zovuta. Kupadera kwa chitsulo cha ductile ndikuti ma graphite ambiri kapena onse amakhala ozungulira, ndipo mawonekedwe ake amawongolera kwambiri magwiridwe antchito a zinthuzo. Pambuyo annealing, kapangidwe metallographic waBlack Iron chubundi ferrite kuphatikiza pearlite pang'ono, ndipo mawonekedwe amakina ndi abwino. .

Mbiri yachitukuko chaDuctile Iron Tubendizodzaza ndi zatsopano komanso zopambana. Chakumapeto kwa zaka za m'ma 1980 ndi koyambirira kwa zaka za m'ma 1990, poyang'anizana ndi kutsekeka kwaukadaulo waukadaulo wopanga chitoliro chakunja kwa centrifugal ductile ndi mikhalidwe yovuta ya chilolezo, 2672nd Factory ya Chinese People's Liberation Army (m'malo mwa Xinxing Casting Pipe) molimba mtima adagwira ntchito yofufuza paokha ndi chitukuko. Mu 1993, woyamba centrifugal ductile chitsulo chitoliro ku China bwinobwino adagulung'undisa pa mzere kupanga, chosonyeza kuti dziko langa lakwaniritsa analumpha kuchokera zikande m'munda uno, ndipo zinatenga zaka zisanu ndi zitatu kumaliza ndondomeko chitukuko cha zaka 40 za mayiko Western. Masiku ano, Xinxing kuponyera chitoliro chapanga mu dziko ndi amphamvu kwambiri centrifugal ductile chitsulo chitoliro wopanga, ndipo nawonso mu chiphunzitso cha mfundo dziko kuponyedwa chitoliro, mosalekeza kulimbikitsa chitukuko cha makampani ductile chitsulo chitoliro.

Mapaipi a Iron Ductile Ali ndi Makhalidwe Osiyanasiyana

1. Mphamvu Zapamwamba ndi Kulimba Kwabwino: Mipope yachitsulo imakhala ndi mphamvu zambiri, ndipo mphamvu zawo zimakhala bwino kwambiri poyerekeza ndi mapaipi achitsulo oponyedwa. Chifukwa graphite imagawidwa mozungulira, kugawanika kwa matrix kumachepa, zomwe zimapangitsa kuti chitolirocho chisaphwanyike pamene chikanikizidwa kwambiri ndi mphamvu. Nthawi yomweyo, ilinso ndi kulimba kwabwino, yokhala ndi elongation yopitilira 10%, ndipo imatha kutengera kutsika kwapansi, kusuntha kwa nthaka ndi zina zambiri. Sizosavuta kuonongeka ndi mapindikidwe, zomwe zimakulitsa kudalirika kwa ntchito ya netiweki ya chitoliro

2. Kukaniza Kwamphamvu kwa Kuwonongeka: Kudzera m'njira zosiyanasiyana zothana ndi dzimbiri, monga zokutira utoto wa phula, matope a simenti, zokutira phula la malasha, epoxy ceramic lining, zokutira simenti ya aluminate, zokutira simenti ya sulfate ndi zokutira za polyurethane, mapaipi achitsulo a ductile amatha kukana dzimbiri kuchokera kuzinthu zosiyanasiyana. Kaya imagwiritsidwa ntchito kunyamula gasi, madzi apampopi, kapena kutayira zimbudzi, imatha kukhalabe yokhazikika m'malo osiyanasiyana ovuta, kukulitsa moyo wautumiki wa mapaipi, ndikuchepetsa mtengo wokonza. .
3. Kusindikiza Kwabwino: Pakamwa pa chitoliro kutengera mawonekedwe osinthika, omwe amatha kuzolowera kusamutsidwa ndi kupindika mkati mwamitundu ina, kupanga mawonekedwe abwino osindikizira pagawo lolumikizira chitoliro, ndikuletsa kutayikira kwamadzimadzi. Panthawi imodzimodziyo, njira yopangira chitoliro chapamwamba kwambiri imatsimikizira kulondola kofanana kwa socket, kupititsa patsogolo ntchito yosindikiza, ndikuonetsetsa kuti kayendedwe ka mapaipi kakuyenda bwino. .
4. Kuyika kosavuta: Poyerekeza ndi mapaipi ena, kulemera kwa mapaipi achitsulo a ductile ndi ochepa, ndipo njira yoyikapo ndiyosavuta. Mawonekedwe ake osinthika amathandizira ogwira ntchito yomanga kuti agwire ntchito yolumikizira, kuchepetsa nthawi yoyika komanso mphamvu yantchito. Pamalo omangapo, kuyika mapaipi kumatha kumalizidwa mwachangu popanda zida zovuta komanso akatswiri amisiri, zomwe zimafupikitsa kwambiri kuzungulira kwa polojekiti ndikuwongolera magwiridwe antchito. .
5. Good Antifreeze Magwiridwe: M'madera ozizira, ntchito ya antifreeze yamapaipi ndiyofunikira. Mipope yachitsulo imakhala ndi mlingo wina wa antifreeze. Malingana ngati sikuli malo ovuta kwambiri, sipadzakhala ming'alu yozizira ndi kuphulika. Izi zimapangitsa kuti azigwiritsidwa ntchito kwambiri popereka madzi, kutentha ndi machitidwe ena a mapaipi m'madera ozizira akumpoto, kupereka ntchito zodalirika kwa okhalamo ndi mabizinesi. .

Ductile Iron Water Pipezakhala zofunika komanso zofunika chitoliro zinthu zamakono zomangamanga zomangamanga ndi makhalidwe awo abwino ntchito. Kuchokera pakupereka madzi a m’tauni ndi kukhetsa madzi kupita ku mpweya wa gasi, kuchokera ku mafakitale kupita ku ntchito zosungira madzi, mapaipi achitsulo a ductile amagwira ntchito yofunika kwambiri m’madera osiyanasiyana ndipo athandiza kwambiri kuonetsetsa kuti anthu ali ndi moyo wabwino komanso kulimbikitsa chitukuko cha zachuma. Ndi kupita patsogolo kosalekeza komanso luso laukadaulo, magwiridwe antchito a mapaipi achitsulo a ductile adzapitilirabe bwino, ndipo kuchuluka kwa ntchito kudzakulitsidwanso. Adzapitirizabe kuwala pomanga zomangamanga m'tsogolomu. .
