Iibholithi zeMonel zihambisa amandla angenakuthelekiswa nanto kunye nokumelana nomhlwa apho izinto zokuqhobosha eziqhelekileyo zisilelayo—iimpompo zamanzi olwandle, iivalvu zegesi emuncu, ii-hydraulic manifolds ezikude nonxweme. Senze oomatshini abangaphezu kwe-12,000 ye-Monel K-500 kunye ne-Monel 400 iibholiti zezindlu zempompo zoxinzelelo oluphezulu ukusukela ngo-2019. Ngamnye uye wasinda kuvavanyo lwesitshizi setyuwa ngaphaya kweeyure ezingama-3,000 ngaphandle kokugoba. Ayingomsebenzi wethiyori leyo. Oko kukuthembeka okungqiniweyo kwintsimi phantsi kwemithwalo yebhayisikile yokwenyani, ukothuka kwe-thermal, kunye ne-chloride-laden atmospheres.
Iibholiti zeMonel azikho nje "intsimbi-engenasici-plus." Ziyi-alloys ze-nickel-copper-ngokuqhelekileyo i-67% ye-nickel, i-23% yobhedu, kunye nezongezo ezincinci kodwa ezibalulekileyo ze-aluminium kunye ne-titanium kwi-K-500. Olu qulunqo ludala i-microstructures eqinile-i-precipitate-hardified microstructures echasene noxinzelelo-i-corrosion cracking engcono kune-316 engenasici okanye i-duplex steels. Kwindibano yevalufa engaphantsi kolwandle yomxhasi omnye, ukutshintsha ukusuka kwi-Inconel 625 bolt ukuya kwi-Monel K-500 kunciphise ukuphindaphindeka kwebholithi ngama-70% ngaphezulu kweenyanga ezili-18. Ngoba? Kuba iMonel igcina amandla esivuno angaphezu kwe-1,000 MPa ngelixa ixhathisa ukubola kwimingxuma kwi-pH 2-12 kunye namaqondo obushushu ukuya kuma-480°C.
Kodwa iibholiti zeMonel zifuna ukuhlonelwa—kungekhona nje ukunconywa. Isantya sokusebenza kwabo sinzima kakhulu. Itephu enye engalungiswanga kakuhle ngexesha lokusika intambo inokwaphula indawo engenanto. Siye sabona abathengi bephulukana neebhetshi zonke kuba besebenzise iitephu zeHSS eziqhelekileyo endaweni yezixhobo zecarbide ezinokuhanjiswa okupholileyo okuqinileyo. I-Monel ikwaqhuba kakubi ubushushu. Ngaphandle kolawulo oluchanekileyo lwe-thermal ngexesha lomatshini, i-annealing yendawo ithambisa ingcambu yentambo-ukusika ubomi bokudinwa kwisiqingatha. Yiyo loo nto sifudumeza izikhewu ukuya kutsho kwi-120 ° C ngaphambi kokuthunga, sebenzisa ii-mills ezipholileyo ezipholileyo ze-cryogenic, kwaye siqinisekise ukuqina kwiindawo ezintathu zeradial kwiqashiso ngalinye. Akukho ndlela imfutshane isindayo kule ngxubevange.
- Ukukhethwa kwezinto eziphathekayo kubaluleke ngaphezu kwenani lebakala. I-Monel 400 ifanele ukubonakaliswa kwamanzi olwandle amileyo; I-Monel K-500 yongeza ukuqina kweminyaka yokugcinwa kwetorque ejikelezayo kwi-shafts yepompo ejikelezayo.
- Ijometri yomsonto ayikhethi-iyasebenza. Imisonto yeFine yeSizwe eManyeneyo (i-UNF) igqwesa i-pitches erhabaxa kwindawo eshukumayo ephezulu ngokusasaza umthwalo we-clamp ngokulinganayo.
- Ukugqitywa komphezulu kuchaphazela ngokuthe ngqo ukuqala komhlwa. I-Ra ≤ 0.4 μm ikhusela i-micro-crevices apho i-chlorides igxininise; i-electropolishing inciphisa iziphene ze-passive-layer ngama-92% xa kuthelekiswa nokupolishwa koomatshini kuphela.
Abanye banokuthi iibholiti zeMonel zibiza kakhulu-ukuya kuthi ga kwi-4 × ngaphezulu kwe-A2-70 engenasici. Nangona kunjalo, iindleko ezipheleleyo zobunini zibalisa ibali elahlukileyo. Umsebenzisi omnye woLwandle lwaseMntla ulandelele ii-hydraulic manifold joints ezili-14 kwiinyanga ezingama-24. Ngeebholiti ezingena stainless, baye benza ukuvalwa okungacwangciswanga okuli-19 ukutshintshwa kwebholithi kunye nokuphinda kutywinwe igasket. Ngeebholiti zeMonel K-500, baqhube iinyanga ezingama-22 ngaphandle kokuvuza okudibeneyo. Abasebenzi, ixesha lokuphumla, kunye neendleko zokuqinisekisa ukhuseleko zehle nge-217,000 yeedola ngonyaka. Ukumelana nokubola akuyonto. Ukugcinwa okumisiweyo-kunye nomngcipheko omisiweyo.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. oomatshini Iibholiti ze-Monel zisebenzisa amaziko e-CNC aqinisekisiweyo e-ISO 9001 anembuyekezo yexesha lokwenene lobushushu. Sifumana iibhilithi eziqinisekisiweyo ze-AMS 4675, siqinisekise ukuhamba okuziinkozo okuziintloko phambi kokuba sibumbe, kwaye senza uhlolo lwe-ultrasonic kwibhetshi nganye ukubona ukubandakanywa komgangatho ongaphantsi komhlaba. Inkqubo yethu ibandakanya isisombululo se-annealing kwi-980 ° C ± 5 ° C, ukucima ngokukhawuleza kwamanzi, emva koko ukuguga kwi-650 ° C kwiiyure ze-16-ngokungqongqo kwi-ASTM B564. Yonke ibholithi ithwala ukulandeleka okugcweleyo: inombolo yobushushu, ingxelo yovavanyo lwe-tensile, uvavanyo lwe-intergranular corrosion (ASTM G28A), kunye nedatha ye-CMM enobungakanani egcinwe iminyaka eli-10. Xa ufuna iibholiti zeMonel ezibamba i-torque emva komjikelezo we-50,000 woxinzelelo kwi-95 ° C brine-asiqikelele. Silinganisa, siqinisekisa, kwaye siqinisekisa.
Ukujonga phambili, iibholiti zeMonel ziyavela ngaphaya kokuqiniswa okumileyo. Ngoku sifaka iigeyiji zoxinzelelo kwi-Monel 400 bolt shanks ukulungiselela ukubekwa esweni kwangaphambili kwexesha lokwenyani kwiziseko zempompo ezibalulekileyo. Uyilo lwesizukulwana esilandelayo ludibanisa i-micro-channels yokuhanjiswa kwe-lubricant e-inline ngexesha lokusebenza-ukwandisa ixesha lenkonzo kwizicelo ezikude ze-oilfield. Ikamva alikho malunga neebholiti zeMonel ezinamandla. Kumalunga nobulumko-eyilwe ngenjongo, iqinisekisiwe ngedatha, kwaye yakhiwe apho ukungaphumeleli kungeyona inketho. Ukuba isicelo sakho sifuna ukungabikho kokulalanisa kwingqibelelo, kwikhemistri, okanye ukungaguquguquki, iibholiti zemoli ayilolona khetho lwakho lungcono. Balukhetho lwakho kuphela.
