Ukufakwa kwe-Monel kufuna okungaphezulu nje kokuchasana nokugqwala-zifuna uzinzo lwe-dimensional phantsi kwebhayisikile ye-thermal, imfezeko ye-microstructural emva kwe-welding, kunye nobomi bokudinwa obuqikelelweyo kwiisekethe eziphezulu zoxinzelelo lwe-hydraulic. Xa ivalve yokutofa kwamanzi olwandle ingaphumeleli kwi-3,200 psi, kunqabile ukuba i-alloy grade ibe nephutha. Ifanelekile: ubunzulu becala leflange, ukugqitywa komphezulu kwigxalaba lokutywina, ukuhambelana kobulukhuni bendawo echatshazelwe bubushushu kwiiyunithi ezingama-500 zemveliso. Kulapho kuyinyaniso ifektri yokufaka imali iyazahlula-kungekhona ngokucaphula i-ASTM B164, kodwa ngokulawula ukuhamba okuziinkozo ngexesha lokutshisa okutshisayo, ukuqinisekisa ukuxhathisa kwe-intergranular corrosion kunye ne-ASTM G28 Indlela ye-A kwiqashiso ngalinye, kunye nokubamba ukunyamezela kwe-± 0.005 mm kwi-threaded engagement length ngaphandle kokuncama amandla okuqina.
Siye sabona abathengi betshintshela abanikezeli ngezihlandlo ezintathu ngaphambi kokuba baqonde unobangela wengcambu yayingekho i-Monel 400 vs. Monel K-500-yayiyi-machining engahambelaniyo yokucoca i-coolant ekhokelela kwi-micro-pitting kwiindawo zokutywinwa koxinzelelo. EQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Sisebenza ngomatshini izifakelo zeMonel hayi “njengenxalenye yentsimbi engaqhelekanga,” kodwa njengonxibelelwano olusebenzayo phakathi koxinzelelo lwenkqubo kunye nokuhlaselwa kokusingqongileyo. Iiseli zethu ze-CNC zisebenza ngokungaphazamiseki kwiiyure ze-72 kwi-Monel 400 i-elbow flanged-kuba isicwangciso sethu se-toolpath sibala amazinga obunzima bomsebenzi 2.3 × ngaphezulu kune-stainless 316, kunye nenkqubo yethu ye-CMM ihlola umkhondo we-thermal drift ngexesha langempela, kungekhona nje ngaphambi nangemva komjikelezo.
Ukudityaniswa ngokuthe nkqo akulolizwi elithetha apha-yindlela esiqinisekisa ngayo ukuba abanye bavavanya ntoni kuphela xa kuhlolwa okokugqibela. Sakha izindlu zempompo ye-Monel zisebenzisa iimolds zotyalo-mali kunye ne-ceramic shell formulations eqinisekisiweyo ye-nickel-copper alloys, emva koko senze isisombululo se-annealing kwi-1,175 ° C ± 5 ° C kunye nokucinywa kwe-nitrogen-purged ukutshixa kwi-austenite efanayo. Akukho ndlu yokuphosa yomntu wesithathu. Akukho mahluko kwibhetshi ukuya kwibhetshi kwisithuba sengalo yedendrite. Xa ukhankanya i-AMS 4953 Monel K-500 yokudibanisa i-actuator ye-subsea, ufumana amanani okushisa anokulandeleka, iingxelo zovavanyo eziqinisekisiweyo ze-intergranular corrosion nganye nge-ASTM G28A, kunye nemisonto echongiweyo eqinisekisiweyo nge-optical thread profilometry-hayi nje ukuhamba / akukho-hamba iigeji. Yiyo loo nto amaqela obunjineli avela kubenzi be-offshore rig eNorway kunye nee-OEMs zehydraulic eTexas zisithumelela imizobo ye-GD&T-enzima enonyamezelo olungqongqo kwiimpawu ezininzi zedatum-kwaye silindele ukuvunywa kwenqaku lokuqala phakathi kweentsuku ezili-12 zokusebenza.
Abanye bathi iifektri zokufaka imali kufuneka zibeke phambili iindleko zempahla ekrwada kunolawulo lwenkqubo. Kodwa ixabiso le-Monel alikho kumxholo we-nickel-kukungabikho kwe-chloride-induced stress corrosion cracking kwi-85 ° C yenkonzo yamanzi olwandle. Sifumana i-Monel 400 billets eziqinisekisiweyo ezinesulfure eqinisekisiweyo ≤0.001% kunye ne-oksijini ≤0.002%, ngenxa yokuba i-sulfure ephakamileyo yenza i-eutectics ephantsi yokunyibilika eqala iinyembezi ezishushu ngexesha lokutshisa okutshisa; ioksijini engaphezulu ikhuthaza iintambo ze-oxide eziye zibe ziindawo zokuqalisa ukuqhekeka phantsi komthwalo webhayisikile. Yonke ikhoyili engenayo ijongana ne-spark emission spectroscopy kunye novavanyo lokuntywiliselwa kwe-ultrasonic ngaphambi kokuba ikhululwe kwimveliso. Asizamkeli "ii-certs ze-mill" - siqinisekisa i-chemistry, ubukhulu bengqolowa (ASTM E112), kunye neempawu zoomatshini ngokwethu. Ukuba isicelo sakho sidinga ubulukhuni be-HAZ obungaphantsi kwe-35 HRC emva kwe-welding ye-orbital, siyafaneleka iinkqubo zethu ze-weld kunye novavanyo olunqamlekileyo kunye novavanyo lokugoba-kungekhona nje ukuxutywa kwe-macro-etching.
Ukusebenza kwehlabathi lokwenyani kuqala ngempendulo yokwenziwa-kungekhona emva kokucaphula, kodwa ngexesha lokuphonononga umzobo. Xa umxhasi wasithumelela i-Monel K-500 ejikelezayo edityanisiweyo ene-0.002 mm iyonke i-ruout spec kubuso obuyi-220 mm ububanzi, siye saphawula umngcipheko woyilo lokusila kwaye sacebisa inkqubo enamanqanaba amabini: ilitye lokusila + elirhabaxa + lokudambisa uxinzelelo + ukugqiba ukucola kwiispindle ezithwele umoya. Olo tshintsho lwehlise izinga lokulahlwa ukusuka kwi-18% ukuya kwi-0.7% kwiiyunithi ezingama-300. Sizinzise le ngcinga kuyo yonke iprojekthi: Ukutolika kwe-GD&T akuyothiyori-imalunga nokwazi ukuba ukunyamezelana kwesikhundla kufuna iphini yesiko le-gage okanye umlinganiselo wolungelelwaniso olusekwe kumbono. Ukusetyenziswa kwe-Monel kwi-oilfield fracturing manifolds, sihlala songeza i-passivation yesibini kwi-citric acid nge-ASTM A967 ukususa ukungcoliswa kwentsimbi yamahhala kwi-machining-emva koko uqinisekise ngovavanyo lwe-sulfate yethusi nge-ASTM A380. Awuyi kufumana elo nyathelo kwiicaphulo ezininzi. Uya kuyifumana kwingxelo yethu yokuhlola inqaku lokuqala.
A ifektri yokufaka imali ufumana ukuthenjwa hayi ngokudwelisa izatifikethi, kodwa ngokuthumela iindawo ezisinda kwimijikelo engama-20,000 kuvavanyo olukhawulezileyo lwenkungu yetyuwa ngaphandle kokugoba-kunye nokubhala yonke i-microhardness yokufunda ecaleni kwe-weld interface. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ihambisa oko kufana ngokusebenzisa isinyithi esilawulwayo, i-metrology egxininisiweyo, kunye nenkqubo yoluleko lwezero-compromise. Ukuba icandelo lakho elilandelayo leMonel kufuneka lisebenze apho ukungaphumeleli kuthetha ixesha lokuphumla, umngcipheko wokhuseleko, okanye ukukhululwa kokusingqongileyo-qala ngokuphononongwa kokwenziwa kwezinto, hayi ukuthelekisa ixabiso.
