Xa iinjineli zichaza Iibholithi zeMoneli kwiivalvu zaselunxwemeni, i-subsea manifolds, okanye iinkqubo zokusetyenzwa kweekhemikhali ezinobushushu obuphezulu, azithengi izinto zokuqhobosha-zikhusela ubuthunywa obubalulekileyo. Ukumelana nokubola kukodwa akwanele. Imiba yozinzo lwe-Thermal. Ukuxhathisa kokukhula phantsi kwemiba yomthwalo ozinzileyo. I-Batch-to-batch consistency kumandla okuqina kunye nokwakheka kweenkozo. Yiyo loo nto ukukhangela kwinyani iibholiti zeebholiti zemoneli—hayi nje umsasazi okanye ivenkile yemisebenzi—akuxoxiswana ngayo.
Siye sabona iiprojekthi ezininzi zilibazisekile ngeebholiti eziphumelele uhlolo olubonakalayo kodwa zasilela kuvavanyo lwesitshizi setyuwa kwiiyure eziyi-1,200. Abanye baqhekeka ngexesha lokuhamba ngebhayisikile ye-thermal phakathi kwe -60 ° C kunye + 450 ° C-kungekhona ngenxa yokuba i-alloy ye-Monel ibuthathaka, kodwa ngenxa yokuba unyango lobushushu obungahambelaniyo okanye ukubanda okungafanelekanga kokusebenza kushiye iingcinezelo ezishiyekileyo zingabonakali de ukuthunyelwa kwentsimi. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Sisebenza ngomatshini iMonel 400 kunye neMonel K-500 iibholithi endlwini, ukuqala ngesitokhwe sebha eqinisekisiweyo ye-ASTM B164, emva koko sisebenzise isisombululo esilawulwayo se-annealing kunye nokuqina kweminyaka ngokwe-AMS 5643. Iqashiso ngalinye lifumana i-spark, i-threadness ephuma kwi-spark kunye ne-hardreaded ephuma kwi-spark, kunye ne-hardreaded emission emission. ukufunyaniswa kwesiphene se-ultrasonic-hayi nje isampula yokuhlola.
Yintoni eyahlula umntu okwaziyo iibholiti zeebholiti zemoneli kumthengisi wempahla yorhwebo? Izinto ezintathu: ulawulo lwe-metallurgical, i-dimensional discipline, kunye nokuqinisekiswa kokusebenza. Okokuqala, i-metallurgy. Ukuqina kwemvula ye-Monel K-500 kuxhomekeke kwi-nickel-aluminiyam-titanium ratios echanekileyo kunye neefestile eziqinileyo zokushisa. Sisebenzisana nomthombo wemathiriyeli ekrwada kunye nababoneleli abaqinisekisiweyo, sigcina ukulandeleka kobushushu obugcweleyo ukuya kwinombolo yelogi ye-ingot, kwaye siqinisekise impendulo yokwaluphala ngamakhuphoni athambileyo asikwe kwibillet efanayo esetyenziselwa ukuveliswa kwebholithi. Okwesibini, ukuqeqeshwa komgangatho. Umsonto weKlasi 3A kwibholiti ye-Monel ufuna ukunyamezelwa kwedayamitha yepitch engqongqo (± 0.0015') kunentsimbi eqhelekileyo engenasici. Amaziko ethu okuguqula i-CNC ye-5-axis abambe i-± 0.0008 'kwi-diameter ebalulekileyo; Ukuqinisekiswa kwe-CMM kubandakanya impazamo yokukhokela intambo, ukuphambuka kwe-angle yeflank, kunye nokuphuma-zonke zixelwe nge-ASME B1.13M. Okwesithathu, ukuqinisekiswa kokusebenza. Asimi kwiigophe zetorque-tension. Kubathengi kwi-oyile kunye negesi, senza iimvavanyo zenkonzo efanisiweyo: ukucwiliswa kweeyure ze-72 kwi-H₂S-saturated brine kwi-120 ° C, kulandelwa ubungqina bokulayisha kwi-90% yamandla esivuno esichaziweyo ngelixa ubeka iliso kwi-microslip okanye ukuphumla.
Abanye banokuxoxa ukuba izinto ezisekwe kwiMonel azikwazi ukuhambelana nezinto ezenziweyo. Bachanekile-kwiibholiti. Kodwa yiyo loo nto kanye sithintela ukuphosa iziqhoboshi zeMonel ngokupheleleyo. Endaweni yoko, sisebenzisa isitokhwe sebha esishushu okanye esitsalwa ngokubanda, emva koko sisebenzise ukujika okuchanekileyo, ukuqengqeleka komsonto (hayi ukusika), kunye ne-electropolishing ekhethwayo yokuphucula ifilimu. Ukuqengqeleka komsonto kucinezela ukwakheka kweenkozo kumphezulu, kwandisa ubomi bokudinwa ukuya kuthi ga kwi-30% xa kuthelekiswa nemisonto esikiweyo. Siqinisekisa oku ngokuvavanya ukukhathala okujikelezayo-beam nganye nge-ASTM E466, ukunika ingxelo ye-S-N i-curves kwi-10⁷ cycles. Kwiijiyometri ezingekho mgangathweni-ezifana neebholiti zeflange ezinezigubu ezidityanisiweyo zokumisa okanye iiflethi ezichasene nokujikeleza-sinobunjineli bezixhobo zesiko ngaphakathi endlwini, sisusa ukulibaziseka komntu wesithathu kunye nokuqinisekisa ukuthotyelwa kwe-GD&T ukusuka kwiprototype yokuqala ukuya kwimveliso epheleleyo.
Ukuthembeka akwakhelwa kwibholiti yeMonel ekuthunyelweni. Yakhelwe kwinkqubo ngaphambi kokuba i-chip yokuqala ibhabha. Oko kuthetha ukuhlolwa kwezinto ezingenayo kunye nabahlalutyi be-PMI-kungekhona nje ii-certs ze-mill. Ukuhlolwa kwenkqubo emva kokuguquka okukrakra, emva kokunyangwa kobushushu, emva kokuqengqeleka kwentambo, nasemva kokucoca okokugqibela. Ukuhlolwa kokugqibela kubandakanya ukuvavanywa kwamasuntswana amagnetic kwiziphene ezingaphantsi komhlaba, ukuqinisekiswa kwe-hydrogen embrittlement bake-out (nge-ASTM F519 nganye), kunye nokupakishwa kwiphepha leVCI elinezalathi zokufuma. Yonke iodolo ithunyelwa ngengxelo epheleleyo yovavanyo: ikhemistri, oomatshini, iziphumo ze-NDT, kunye nedatha elinganayo egxininiswe liqela lethu le-QA eqinisekisiweyo ye-ISO 9001. Sisebenzela abathengi abasuka eHouston ukuya eHamburg naseSingapore-hayi ngabarhwebi, kodwa ngentsebenziswano yobunjineli ngokuthe ngqo. Xa iibholiti zakho zempompo zezindlu zijongene ne-20,000 ye-psi yokwahlukana koxinzelelo kunye ne-chloride-laden steam, "ilungile ngokwaneleyo" ayikho inketho. Ukuchaneka akukhethi. Ukulandeleka akunyanzelekanga. Amava ngeMonel ayikhethi. Khetha a iibholiti zeebholiti zemoneli ephatha yonke ibholiti njengenxalenye kwinkqubo yokuxhasa ubomi-kuba kwiimeko ezininzi, kunjalo.
