Ibikoresho bya Monel bikemura ikibazo kimwe gihoraho abajenjeri bahura nacyo buri munsi: kunanirwa kwangirika mubidukikije. Amazi yo mu nyanja, gaze isharira, inzira ya acide - byose byonona ibyuma bisanzwe bitagira umwanda. Twabonye flanges yacitse nyuma y'amezi 18 muri offshore hydraulic manifolds. Twasimbuye Monel 400 adaptateur inshuro ebyiri muri retrofit imwe yumusemburo wa desalination kuko uwatanze isoko yambere yasimbuye UNS N04400 nivanga rya nikel-umuringa rihendutse ridafite annealing ikwiye. Niyo mpamvu "monel ikwiye" atari ijambo ryishakisha gusa-ni ibisobanuro bitwara uburemere.
Impamvu Monel Yitandukanije-Ntabwo ari Nickel Alloy gusa
Imisemburo ya Monel-cyane cyane Monel 400 na Monel K-500 - ni nikel-umuringa wa nikel hamwe na nikel 63-70%, umuringa 20-34%, hamwe na fer, manganese, na silikoni. Kurwanya kwabo biva murwego rwo kwikiza oxyde, ntabwo ari chromium nkibyuma bitagira umwanda. Ibyo bivuze ko barwanya gutobora, guhangayika kwangirika, hamwe nisuri-kwangirika aho 316 idafite ingese yananiwe vuba. Mubigeragezo-byukuri kwisi kubakiriya bacu, Monel 400 fitingi yamaze 4.2 × kurenza 316 SS mumashanyarazi ya hydraulic igenzura. Monel K-500 yongeramo aluminium na titanium kugirango imvura igwe - nibyiza kubihuza umuriro mwinshi cyangwa ibiti byo mu nyanja bikenera imbaraga n’ubudahangarwa ku gitero cy’amazi yo mu nyanja.
Ariko amanota yibikoresho yonyine ntabwo yemeza imikorere. Twapimye itandukaniro rigera kuri 12% muburyo bwo kurwanya ruswa hagati yimyenda ya Monel ikomoka mu nsyo zitandukanye - niyo byemejwe na ASTM B164 cyangwa ASME SB-164. Itandukaniro? Gushyushya uburyo bwo kuvura no kurangiza hejuru. Igisubizo gikwiye-cyometse kuri Monel 400 ikwiranye, itoraguwe kandi ihindagurika, itanga ubushobozi bumwe bwamashanyarazi hejuru yubuso bwayo. Gukina gukonje bidakwiye byerekana microsegregation, ikora selile ya galvanic iri gutemba. Niyo mpamvu tugenzura buri cyiciro cya Monel-ntabwo dukoresheje urusyo gusa, ahubwo hamwe na mapping ya EDS hamwe na ASTM G48 yipimishije chloride mbere yo koherezwa.
Aho Monel Fittings Mubyukuri Gutanga ROI-Ntabwo ari Impapuro Zihariye
Porogaramu eshatu zitandukanya ibitekerezo nagaciro:
- Umuvuduko ukabije wa hydraulic manifolds mumodoka yubuhanga bwa offshore-aho gusiganwa ku magare yumuriro + umunyu wijimye + kunyeganyega bisaba kumeneka zeru mumasaha 15,000 yo gukora. Umuringa usanzwe cyangwa 316 SS ibikoresho hano bisaba gusimburwa buri gihembwe; Monel 400 imara imyaka 3+ idafite kashe.
- Amateraniro yo kuvoma gutunganya amazi mabi ya chlorine cyangwa H₂S yuzuye kondensate. Hano, Monel K-500 ihuriro ry’amashyirahamwe arwanya guhungabana mugihe cyo kuyisenya - aho ububabare busanzwe hamwe na duplex idafite ubundi buryo.
- Amavuta ya gazi yo gutera inshinge, cyane cyane ibipimo bya methanol cyangwa ingese zibuza imiyoboro. Monel 400 ibikoresho byo guhunika bigumana ubunyangamugayo kuri -40 ° C kugeza kuri + 120 ° C, birinda kuvunika kuvunika cyangwa gukonja gukonje bigaragara muri bronzes zimwe na nikel-aluminium.
Ntabwo dusaba Monel kumurongo wamazi ufite ibyago bike cyangwa sisitemu yo mu kirere. Birakabije-kandi bihenze. Ariko aho gutsindwa bisobanura gutinda, ibyago byumutekano, cyangwa kurekura ibidukikije, ikiguzi-kumasaha-yo-kwizerwa kigabanuka cyane.
Niki Cyakora Monel Ihuza Mubyukuri-Kurenga Kode ya Alloy
Monel ikwiranye ntabwo yananiwe guhitamo ibintu - ahubwo biva mubikorwa byo kubura. Turakurikirana imizi ine isubirwamo mumasoko agaruka:
- Ingingo ya geometrie idahuye. Igipimo gisanzwe cya 60 ° V-kanda isiga micro-amarira ahinduka urubuga rwo gutangiriraho. Dukoresha kanda-yubutaka ifite 3 ° inguni zubutabazi hamwe ningingo ya nyuma yo gutunganya imashini-yoroheje annealing.
- Guhuza Galvanic: Bolting Monel 400 flanges kumashanyarazi ya karubone idafite akato ka dielectric itumira kwangirika kwihuse kuri interineti. Turerekana gasketi zidatwara kandi zikoresha ibikoresho byamaboko - ntabwo ari inyongera.
- Kwandura hejuru: Ibice by'icyuma biva mubikoresho bisangiwe byinjijwe hejuru ya Monel, kubora no gutesha agaciro imiterere ya firime. Utugingo ngengabuzima twa CNC dukoresha Monel-gusa-nta kwanduzanya hamwe n'ibice by'ibyuma bitagira umwanda.
- Uturere twangirika: Monel irasudwa, ariko guhitamo kwuzuza bidakwiye cyangwa kugenzura ubushyuhe bwa interpass bituma imvura igwa hagati ya karbide. Kubikoresho byo gusudira Monel, dukoresha ERNiCu-7 yuzuza hamwe na 150 ° C max interpass temp hamwe no gutoragura nyuma yo gusudira.
Ibi ntabwo ari impungenge. Ni amasomo yavuye mu mirima 217 yoherejwe hakurya y'inyanja y'Amajyaruguru, uruganda rutunganya Aziya yo mu majyepfo y'uburasirazuba bwa Aziya, hamwe na sitasiyo za pompe zo mu nyanja ya Amerika.
Guhitamo Utanga-Iyo "Yemejwe" Ntabwo bihagije
Umucuruzi wese arashobora kohereza ASTM B164 yemewe na Monel. Bake barashobora kwerekana uburinganire buringaniye mubunini, gukurikira ubushyuhe bwo kuvura ubushyuhe kuri buri gice, cyangwa kwemeza imikorere ya ruswa kuri chimie yawe yihariye. Muri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Dufata umusaruro ukwiranye na monel nka sisitemu ifunze-gufunga: ibikoresho fatizo biva mu byemezo bibiri (urusyo + mu nzu OES), CNC ikora imashini ikurikirana ubushyuhe bwigihe, hamwe nubugenzuzi bwa nyuma dukoresheje umunyu-spray + electrochemic impedance spectroscopy. Buri cyiciro gitwara ibisobanuro byuzuye: nimero yo gushonga, itariki yo guhimba, umugozi uteganijwe wa anneal, raporo ya CMM, hamwe namakuru yikizamini cya ruswa. Nta na kimwe kidasanzwe.
Kwizerwa ntabwo byubatswe. Yubatswe mubikorwa-buri gihe. Mugihe ubutaha bukomeye hydraulic manifold ikeneye ibikoresho bya Monel bitazagutangaza mugitangira, reba kera datasheet. Reba kugenzura inyuma yicyemezo.
