Zopangira ma monel zimathetsa vuto limodzi lomwe mainjiniya amakumana nalo tsiku lililonse: kulephera kwa dzimbiri m'malo ankhanza. Madzi a m'nyanja, mpweya wowawasa, mitsinje ya acidic - zonsezi zimatafuna zitsulo zosapanga dzimbiri. Tawona ma flanges akuphwanyidwa pambuyo pa miyezi 18 m'ma hydraulic manifolds. Tasintha ma adapter a Monel 400 kawiri muzomera imodzi yochotsa mchere chifukwa wotsatsa woyamba adalowetsa UNS N04400 ndi kuphatikiza kotchipa kwa nickel-copper komwe sikumangirira bwino. Ndicho chifukwa chake "kuyika ndalama" sikungofuna kufufuza-ndizolemba zomwe zimalemera.
Chifukwa Chake Monel Imasiyanitsidwa—Osati Nickel Alloy Ina
Ma aloyi a Monel-makamaka Monel 400 ndi Monel K-500-ndi zida za nickel-copper zokhala ndi faifi tambala 63-70%, 20-34% yamkuwa, ndi trace iron, manganese, ndi silicon. Kukaniza kwawo kumachokera kumalo odzichiritsa okha, osati chromium ngati zitsulo zosapanga dzimbiri. Izi zikutanthauza kuti amakana kuponya, kupsinjika kwa dzimbiri, ndi kukokoloka komwe 316 zosapanga dzimbiri zimalephera mwachangu. Pakuyesa kwapadziko lonse lapansi pamakasitomala athu onse, zoyikira za Monel 400 zidatenga nthawi yayitali 4.2× kuposa 316 SS m'ma block blocks a brine-saturated hydraulic control. Monel K-500 imawonjezera aluminiyumu ndi titaniyamu kuti mvula ikhale yolimba - yabwino polumikizana ndi torque yayikulu kapena ma valve apansi pa nyanja omwe amafunikira mphamvu zonse komanso chitetezo cham'madzi a m'nyanja.
Koma kalasi yakuthupi yokha sikutsimikizira kuti ntchitoyo ikugwira ntchito. Tayesa mpaka 12% kusiyanasiyana pakukana kwa dzimbiri pakati pa zoyika za Monel zochokera ku mphero zosiyanasiyana — ngakhale zitatsimikiziridwa ku ASTM B164 kapena ASME SB-164. Kusiyana kwake? Kusasinthika kwa chithandizo cha kutentha ndi kumaliza komaliza pamwamba. Monel 400 yolumikizidwa bwino, yoziziritsa komanso yosasunthika, imapereka kuthekera kwamagetsi kofananira padziko lonse lapansi. Kuponyedwa kozizira kosayenera kumawonetsa microsegregation, kupanga ma cell a galvanic akuthamanga. Ichi ndichifukwa chake timatsimikizira gulu lililonse la Monel-osati ndi ma cert a mphero, koma ndi mapu a EDS omwe ali patsamba ndi kuyesa kwa ASTM G48 ferric chloride musanatumize.
Kumene Zopangira Ma Monel Kwenikweni Zimapereka ROI-Osati Mapepala Okha
Ntchito zitatu zimasiyanitsa chiphunzitso ndi mtengo:
- High-pressure hydraulic manifolds m'magalimoto aukadaulo akunyanja - komwe kukwera njinga yotentha + nkhungu yamchere + kugwedezeka kumafuna zero kutayikira pa maola 15,000 ogwirira ntchito. Zida zamkuwa zokhazikika kapena 316 SS pano zimafuna kusinthidwa kotala; Monel 400 imatha zaka 3+ popanda kuwonongeka kwa chisindikizo.
- Misonkhano yoyamwa pompo kusamalira madzi otayidwa a chlorine kapena H₂S-laden condensate. Apa, maukwati a Monel K-500 amakana kukwiya panthawi yokonza disassembly-malo opweteka omwe amakhala ndi njira zina zosapanga dzimbiri.
- Mafuta ndi gasi jakisoni wamankhwala, makamaka omwe amamwa methanol kapena corrosion inhibitors kukhala mapaipi. Ma compression a Monel 400 amasunga umphumphu pa -40 ° C mpaka +120 ° C, kupewa kuthyoka kapena kuzizira kowoneka mu bronzes wa nickel-aluminium.
Sitikupangira Monel kwa mizere yocheperako yamadzi kapena makina am'mlengalenga. Ndizokwera mtengo - komanso zokwera mtengo. Koma pamene kulephera kumatanthauza kutsika, chiwopsezo cha chitetezo, kapena kumasulidwa kwa chilengedwe, mtengo wa ola limodzi-wodalirika umatsika kwambiri.
Zomwe Zimapangitsa Kuti Kuyika kwa Monel Kugwire Ntchito - Kupitilira Khodi ya Alloy
Kuyika kwa Monel sikulephera chifukwa cha kusankha kwakuthupi-koma kuchokera ku mipata yopha. Timapereka zifukwa zinayi zomwe zimabwerezedwa mobwerezabwereza m'munda wobwerera:
- Kusagwirizana kwa ulusi wa geometry: Kutsika kwamafuta kwa Monel komanso kulimba kwa ntchito kumafuna kulolerana kolimba pa ulusi wotsogolera ndi ngodya zakumbali. Kupopera kwa ulusi wa 60 ° V kumasiya misozi yaying'ono yomwe imakhala malo oyambira. Timagwiritsa ntchito matepi apansi okhazikika okhala ndi ma angles a 3 ° ndi ma anneal ofunikira pambuyo pa makina ochepetsa kupsinjika.
- Kugwirizana kwa Galvanic: Bolting Monel 400 flanges kuti mpweya zitsulo piping popanda dielectric kudzipatula kumapangitsa dzimbiri imathandizira pa mawonekedwe. Timatchula ma gaskets osakhala a conductive ndi zida zotsekera manja - osati zowonjezera.
- Kuwonongeka kwapamtunda: Tizilombo tachitsulo kuchokera ku zida zomwe timagawana timayika pamalo a Monel, kuchitira dzimbiri komanso kufooketsa mapangidwe amafilimu omwe amangokhala. Maselo athu a CNC amayendetsa Monel-okha-palibe kuipitsidwa ndi zitsulo zosapanga dzimbiri kapena aloyi.
- Zone zowola weld: Monel ndi yowotcherera, koma kusankha kosayenera kwa filler kapena kuwongolera kutentha kwa interpass kumapangitsa mpweya wa intergranular carbide. Pazowonjezera zowotcherera za Monel, timagwiritsa ntchito ERNiCu-7 filler yokhala ndi kutentha kwapakati kwa 150 ° C max ndi pickling pambuyo pa weld.
Izi sizongoganizira chabe. Ndi maphunziro ochokera kumadera 217 otumizidwa kudutsa North Sea nsanja, Southeast Asia refineries, ndi US Gulf Coast pompa.
Kusankha Wopereka -Pamene "Wotsimikizika" Sikokwanira
Wogulitsa aliyense amatha kutumiza Monel yotsimikizika ya ASTM B164. Ndiochepa omwe angatsimikizire kukhazikika kwamitundumitundu, kutsata njira zochiritsira kutentha pagawo lililonse, kapena kutsimikizira magwiridwe antchito amadzimadzi anu enieni. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., timachita kupanga monel koyenera ngati njira yotsekeka: zopangira zopangira ndi certification wapawiri (mphero + m'nyumba OES), CNC machining ndi kuyang'anira nthawi yeniyeni matenthedwe, ndikuwunika komaliza pogwiritsa ntchito mchere-utsi + chabe + electrochemical impedance spectroscopy. Gulu lililonse limakhala ndi kutsata kwathunthu: nambala yosungunuka, tsiku lopangira, chipika chopindika, lipoti la CMM, ndi data yoyesa dzimbiri. Palibe kuchotserapo.
Kudalirika sikumangidwira mu alloy. Zimapangidwa mu ndondomeko - nthawi zonse. Mukafuna ma hydraulic hydraulic manifold anu otsatira omwe sangakudabwitseni poyambitsa, yang'anani kupyola ndandanda. Onani zowongolera kumbuyo kwa satifiketi.
