1.Application Case ntawm Monel K500 hauv Nuclear Kev Lag Luam

Monel K500 yog siv los tsim qee qhov chaw ntawm lub tshuab nqus dej siab (PWR) cores, xws litswj rod guide tubesthiabroj sib dhos spacers. Cov Cheebtsam no yuav tsum tiv taus qhov kub thiab txias, siab siab, thiab muaj zog neutron hluav taws xob rau lub sijhawm ntev nyob rau hauv lub reactor coolant ib puag ncig. Cov nag lossis daus- cov qauv tawv ntawm Monel K500 ua kom lub zog siab thiab qhov ruaj khov, thaum nws cov corrosion kuj zoo heev tuaj yeem tiv taus corrosion ntawm boric acid-laden coolant thiab tiv thaiv cov khoom tsis ua hauj lwm los ntawm kev ntxhov siab corrosion cracking (SCC).

Primary Coolant System Valves thiab Fasteners

Lub hauv paus coolant system ntawm nuclear fais fab nroj tsuag yog lub hauv paus ntsiab lus rau lub tshav kub hloov lwm lub tsev, thiab nws cov Cheebtsam yog nyob rau hauv kev pab cuam nyob rau hauv hnyav tej yam kev mob ntawm kub siab (txog 300 degree), siab siab (li 15 MPa) thiab muaj zog corrosion. Monel K500 yog siv los tsimvalve stems, valve discs thiab siab -strength fastenersrau qhov system no. Piv nrog rau cov hlau tsis zoo tib yam, nws muaj kev tiv thaiv zoo dua rau pitting corrosion thiab crevice corrosion nyob rau hauv siab -kub dej, thiab muaj peev xwm tswj tau cov qauv kev ncaj ncees rau lub neej ntev kev pab cuam (feem ntau 40 xyoo los yog ntau tshaj).

Siv cov roj cia Cov Cheebtsam

Siv cov roj sib txuas tom qab ua haujlwm reactor yuav tsum tau muab cia rau hauv cov pas dej da dej rau ntau xyoo kom txias thiab txo cov xov tooj cua. Monel K500 yog siv los uasiv roj cia racksthiabpas dej ua ke hauv kev txhawb nqa cov qauv. Nyob rau hauv lub sij hawm ntev - ib puag ncig immersion ib puag ncig ntawm lub pas dej da dej, nws tuaj yeem tiv thaiv corrosion ntawm chloride ions thiab lwm yam impurities hauv dej, thiab nws lub zog siab tuaj yeem ua rau hnyav hnyav ntawm cov khoom siv roj, tsis txhob khib deformation lossis tawg.

Nuclear khib nyiab kho cov cuab yeej

Hauv cov txheej txheem ntawm kev kho cov khib nyiab nuclear, tshwj xeeb tshaj yog nyob rau hauv kev kho cov kua hluav taws xob pov tseg, Monel K500 yog siv los tsimcorrosion-cov twj tso kua mis, cov kav dej thiab cov khoom siv hluav taws xob. Qhov nruab nrab hauv cov khoom siv no feem ntau muaj cov kua qaub lossis alkaline radioactive daws. Cov hlau tsis kam tiv thaiv cov tshuaj tiv thaiv corrosion thiab hluav taws xob ruaj ntseg tuaj yeem tiv thaiv cov khoom xau ntawm cov khoom siv hluav taws xob thiab ua kom muaj kev nyab xeeb ntawm cov txheej txheem kho.

2. Cov khoom siv ua los ntawm Monel K500 hauv kev lag luam Petrochemical

Cov khoom siv Downhole rau Kev Tshawb Fawb Roj thiab Roj

Nyob rau hauv ntug dej hiav txwv los yog siab - cov roj sulfur thiab roj qhov dej, qhov chaw hauv qab yog qhov muaj kev kub ntxhov, kub siab, thiab cov ntsiab lus siab ntawm hydrogen sulfide (H₂S) thiab chloride ions, uas yog nquag ua rau sulfide stress corrosion cracking (SSCC) thiab pitting corrosion ntawm hlau. Monel K500 yog siv los tsimdownhole kev ruaj ntseg li qub, xyaum me ntsis Cheebtsam, thiab sucker rods. Nws lub zog tensile siab (txog 1100 MPa tom qab kev laus) thiab SSCC zoo heev tuaj yeem tiv taus lub siab thiab corrosion ntawm qhov chaw ib puag ncig, thiab zam cov khoom siv tsis ua haujlwm thiab cov roj thiab cov pa tawm.

Refining thiab Chemical Processing Pl-ants

Hauv cov txheej txheem roj refining xws li hydrodesulfurization thiab hydrocracking, cov tshuaj tiv thaiv nruab nrab muaj hydrogen sulfide, hydrochloric acid, thiab lwm yam corrosive. Monel K500 yog siv los tsimThaum tshav kub kub exchanger raj, reactor internals, thiab catalyst txhawb daim phiaj. Cov hlau tsis kam ua rau siab -kub hydrogen corrosion thiab sulfur corrosion tuaj yeem ua rau lub neej ntev ntawm cov khoom siv. Nyob rau tib lub sijhawm, nws lub zog zoo txhua yam tuaj yeem dais lub siab ntawm cov tshuaj tiv thaiv kab mob thiab kev thauj khoom ntawm cov catalyst.

Corrosion{0}}Resistant Valves thiab Pumps

Li qub thiab cov twj tso kua mis yog cov khoom siv hluav taws xob xa mus rau hauv cov nroj tsuag petrochemical. Rau cov xov xwm uas muaj cov khoom muaj zog corrosive xws li acids, alkalis, thiab ntsev, Monel K500 yog siv los uavalve lub cev, valve cores, twj impellers, thiab ncej tes tsho. Piv nrog cov pa roj carbon steel thiab cov hlau tsis zoo tib yam, nws muaj qhov zoo dua corrosion kuj nyob rau hauv cov kua qaub thiab alkali sib xyaw, thiab nws cov hnav tsis kam tuaj yeem txo qhov kev puas tsuaj ntawm cov khoom los ntawm cov kua nplaum, txo cov kev tu ntau zaus.

Offshore Petrochemical Facilities

Offshore platforms thiab FPSO (Floating Production Storage and Offloading) units yog nyob rau hauv ib puag ncig marine nrog cov av noo siab, cov ntsiab lus ntsev siab, thiab muaj zog corrosiveness. Monel K500 yog siv los tsimcov yeeb nkab txhawb nqa, flange fasteners, thiab seawater cooling system Cheebtsam. Nws tsis kam mus rau seawater corrosion thiab crevice corrosion tuaj yeem tiv thaiv kev xeb ntawm cov khoom siv raug rau hauv hiav txwv ib puag ncig, thiab nws lub zog siab tuaj yeem dais qhov kev vibration thiab load ntawm lub platform nyob rau hauv dej hiav txwv hnyav.

Liquefied Natural Gas (LNG) Cov Khoom Siv Ua Haujlwm

Hauv cov txheej txheem LNG liquefaction thiab khaws cia, qhov kub thiab txias yog qis li -162 degree. Monel K500 yog siv los ualow-kub valve stems thiab fastenersrau LNG nroj tsuag. Nws muaj qhov tsis zoo - kub toughness thiab yuav tsis ua txias brittleness nyob rau hauv ultra- qhov kub thiab txias ib puag ncig. Nyob rau tib lub sijhawm, nws tuaj yeem tiv thaiv corrosion ntawm liquefied natural gas thiab nws cov impurities, ua kom muaj kev nyab xeeb ntawm LNG system.
