Lapho onjiniyela bayacacisa Amabhawudi eMoneli kuma-valve asogwini lolwandle, ama-subsea manifolds, noma amasistimu okucubungula amakhemikhali asezingeni eliphezulu, awathengi izinto zokubopha—aqinisekisa ubuqotho obubaluleke kakhulu. Ukumelana nokugqwala kukodwa akwanele. Ukuzinza kwe-thermal kubalulekile. Ukumelana nokukhula ngaphansi kwezindaba zomthwalo oqhubekayo. Ukungaguquguquki kwe-batch-to-batch emandleni aqinile kanye nesakhiwo sokusanhlamvu kubalulekile. Ngakho-ke ukutholakala kweqiniso imboni yamabhawudi e-monel—hhayi nje umsabalalisi noma isitolo semisebenzi—akuxoxiswana ngaso.
Sibone amaphrojekthi amaningi abambezeleka ngamabhawodi aphumelele ukuhlolwa okubonakalayo kodwa ahluleka ukuhlolwa kwesifutho sikasawoti ngamahora angu-1,200. Abanye baqhekeke ngesikhathi sokuhamba ngebhayisikili elishisayo phakathi kuka--60°C no-450°C—hhayi ngoba ingxubevange ye-Monel ibuthakathaka, kodwa ngenxa yokuphathwa kokushisa okungahambisani noma ukusebenza okubandayo okungafanele kushiye izingcindezi eziyinsalela zingabonwa kwaze kwaba yilapho kuthunyelwa insimu. Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., sishicilela amabhawodi e-Monel 400 kanye ne-Monel K-500 endlini, siqala ngesitoko sebha esiqinisekisiwe se-ASTM B164, bese sisebenzisa isixazululo esilawulwayo sokuhlanganisa kanye nokwenza lukhuni ubudala nge-AMS 5643 ngayinye. Yonke inkatho ithola inhlansi, ukukhishwa kwentambo okuqinile kanye nokukhishwa kwe-hardread ukutholwa kwamaphutha nge-ultrasonic—hhayi nje amasampula okuhlola.
Yini ehlukanisa umuntu onekhono imboni yamabhawudi e-monel kusuka kumnikezeli wempahla? Izinto ezintathu: ukulawulwa kwe-metallurgical, isiyalo sobukhulu, nokuqinisekisa ukusebenza. Okokuqala, i-metallurgy. Ukuqina kwemvula kwe-Monel K-500 kuncike kuzilinganiso ezinembile ze-nickel-aluminium-titanium namawindi ashisayo aqinile. Sihlanganisa izinto ezingavuthiwe nabahlinzeki abaqinisekisiwe, sigcina ukulandeleka okugcwele kokushisa kuze kufike kunombolo yelogi ye-ingot, futhi siqinisekisa impendulo yokuguga ngamakhuphoni aqinile asikwe ku-billet efanayo esetshenziselwa ukukhiqizwa kwebhawudi. Okwesibili, isiyalo sobukhulu. Uchungechunge Lwekilasi 3A kubhawodi ye-Monel ludinga ukubekezelela okuqinile kobubanzi bokuphakama (±0.0015') kunensimbi engagqwali evamile. Izikhungo zethu zokujika ze-CNC ze-5-axis zibamba u-±0.0008' kumadiamitha abalulekile; Ukuqinisekiswa kwe-CMM kufaka phakathi iphutha lokuhola intambo, ukuchezuka kwe-engeli yeflank, kanye nokuphumayo—konke kubikwe nge-ASME B1.13M ngayinye. Okwesithathu, ukuqinisekiswa kokusebenza. Asigcini kumajika e-torque-tension. Kumakhasimende kuwoyela negesi, senza izivivinyo zesevisi ezilingisa: ukucwiliswa kwamahora angu-72 ku-H₂S-saturated brine ku-120°C, okulandelwa ukulayisha okuwubufakazi ukuya ku-90% wamandla esivuno acacisiwe kuyilapho siqapha ukuslip kancane noma ukuphumula.
Abanye bangase baphikise ngokuthi izingxenye ze-Monel ezisekelwe ekulingiseni azikwazi ukufana nezinto ezibonakalayo ezenziwe. Balungile-ngamabhawudi. Kodwa yingakho impela sigwema ukusakaza izibophelelo ze-Monel ngokuphelele. Esikhundleni salokho, sisebenzisa isitokwe sebha efojiwe eshisiwe noma edonswa ngokubanda, bese sifaka ukujika okunembayo, ukugoqa intambo (hhayi ukusika), kanye nokupholishwa ngogesi ongakukhetha ukuze kuthuthukiswe ifilimu yokwenziwa. Ukugingqa uchungechunge kucindezela ukwakheka okusanhlamvu phezulu, okwandisa impilo yokukhathala kufika ku-30% uma kuqhathaniswa nezintambo ezisikiwe. Siqinisekisa lokhu ngokuhlolwa kokukhathala okujikelezayo kwe-ASTM E466 ngayinye, sibika amajika e-S-N emijikelezweni engu-10⁷. Kumajiyometri angajwayelekile—njengamabhawodi e-flange anamalugi aphansi ahlanganisiwe noma amafulethi avimbela ukuzungezisa—sinjiniyela amathuluzi angokwezifiso asendlini, sisusa ukubambezeleka kwezinkampani zangaphandle futhi siqinisekisa ukuthobela kwe-GD&T kusukela kumfuziselo wokuqala kuya ekukhiqizweni okugcwele.
Ukuthembeka akwakhelwa kubhawudi ye-Monel ekuthunyelweni. Yakhelwe ohlelweni ngaphambi kokuthi kundiza i-chip yokuqala. Lokho kusho ukuhlola impahla engenayo nabahlaziyi be-PMI—hhayi nje izitifiketi zokugaya. Ukuhlolwa okungaphakathi kwenqubo ngemva kokuphenduka kanzima, ngemva kokwelashwa kokushisa, ngemva kokugingqa intambo, nangemuva kokuhlanza okokugcina. Ukuhlola okokugcina kuhlanganisa ukuhlolwa kwezinhlayiyana kazibuthe zokulimala okungaphansi komhlaba, ukuqinisekiswa kwe-bake-out ye-hydrogen embrittlement (nge-ASTM F519 ngayinye), kanye nokupakishwa ephepheni le-VCI elinezinkomba zomswakama. Wonke ama-oda athunyelwa ngombiko ogcwele wokuhlola: amakhemikhali, imishini, imiphumela ye-NDT, kanye nedatha enobukhulu egxivizwe ithimba lethu le-QA eliqinisekisiwe le-ISO 9001. Sisebenzela amakhasimende asuka e-Houston kuya e-Hamburg nase-Singapore—hhayi ngama-broker, kodwa ngokubambisana okuqondile kobunjiniyela. Uma amabhawodi ezindlu zakho zephampu ebhekene nomfutho ohlukile we-psi ongu-20,000 kanye nesitimu esigcwele i-chloride, "okwanele" akuyona inketho. Ukunemba akuyona inketho. Ukulandelelwa akuyona inketho. Okuhlangenwe nakho nge-Monel akuyona inketho. Khetha a imboni yamabhawudi e-monel ephatha wonke amabhawodi njengengxenye yesistimu yokusekela ukuphila—ngoba ezimweni eziningi, kunjalo.
