ASTM B423 / B423Myog tus qauv kev tshwj xeeb rau"Seamless yeeb nkab thiab raj"Ua los ntawm ib qho nickel tshwj xeeb - hlau {}} chromium {}} molybdenum {}} tooj liab alloy.
Cov qauv no tau mob siab rau ib qho, zoo heev alloy: tsis yog n08825, N08221, NEX} {{{{}}} ua haujlwm rau cov kev pabcuam corrosive.
Tus qauv ua rau cov tshuaj lom neeg muaj pes tsawg leeg, qhov ntev dua, kev ua kom ntev, thiab kuaj cov kav dej seamless thiab cov leeg ua los ntawm cov alloy no.

Cov khoom lag luam
1. Tsis yog N08825 (Alloy 825) -} Cov khoom siv ua haujlwm ntau yam
Qhov no yog thawj alloy rau uas ASTM B423 tau tsim. Nws yog titanium - Stabivized Austenitic Nickel {}}} chromium alloy.
Vim li cas nws tau siv:Nws cov ntawv sib luag heev muab kev tiv thaiv zoo heev rau ntau qhov kev xeb ib puag ncig.
Corrosion Kuj:
Txo cov kua qaub:Tsis kam sulfuric thiab phosphoric acids vim mo thiab CU.
Oxidizing acids:Tsis kam ua nitric vim yog cov ntsiab lus siab.
Chlorides:Cov ntsiab lus Ni cov ntsiab lus muab kev tiv thaiv rau chloride kev ntxhov siab corrosion (SCC).
Cov Ntawv Thov:Kev Lag Luam Kev Lag Luam Kev Lag Luam, Pickling Tso Tsheb Hlau Luam Thiab Cov Khoom Siv Roj Thiab Roj Tubing, Phosphoric Acid Evaporators, Nuclear Roj reprocessor.
2. Uncal N08221 (Alloy 22) {{{{}} Cov niaj hnub, weldable awor
Qhov no alloy yog ib qho dual -} nb) kev hloov kho ntawm alloy 825, tsim qauv los daws nws cov kev txwv thaum vuam thiab cov ntaub thaiv.
Vim li cas nws tau siv:Txhawm rau muab tib yam zoo tib yam corrosion tsis kam raws li 825 tab sis nrog superior tiv taus rausiab zoo(Qhov tsim ntawm chromium carbides ntawm cov ciaj ciam av thaum vuam, uas depletes chromium thiab txo corrosion tsis kam).
Cov ntsiab lus tseem ceeb:Lub ob txhaislilization ob leeg ua kom zoo dua cov qauv kev ruaj ntseg tom qab raug cov kev xaiv kub (piv txwv li kev xaiv hluav taws xob lossis kev xaiv tau zoo tshaj plaws rau cov ntawv fab tshiab thiab welded qauv.
Cov Ntawv Thov:Tib yam li N08825, tab sis tshwj xeeb xaiv rau kev tsim kho tshiab uas vuam tshuaj ntau heev {1} welded kev hloov hluav taws xob, FGD system duas.
3. Tsis yog N06845 (Alloy 945) - Lub siab- lub zog tshwj xeeb
Qhov no alloy yog siv tshuaj ua kom tiav kom ua tiav lub zog siab heev thaum tswj cov khoom lag luam zoo corrosion.
Vim li cas nws tau siv:Rau cov ntawv thov uas ob qho tib si zoo siab corrosion tsis kam thiabHeev Heev Cov Tshuab Zog Heevyuav tsum tau.
Cov ntsiab lus tseem ceeb:Nws tuaj yeem yogdaus tawv tawv tawv(hnub nyoog) tom qab tov aneging. Nyob rau hauv lub hnub nyoog muaj zog, nws tuaj yeem ua tiav cov txiaj ntsig zoo tshaj li ob npaug ntawm N08825 lossis N08221 hauv lawv Annealed State.
Cov Ntawv Thov:
Roj & Roj:Siab - muaj zog downhole lub zog tubular, tubing hanging, cov khoom noj ua ke, thiab cov khoom siv routea rau hauv cov kev pab qaub.
Aerospace:Siab - lub zog Cheebtsam uas yuav tsum tiv thaiv corrosion.
High - Cov txheej txheem siab:Qhov twg phab ntsa thickness xav tau txo qis qis thaum tswj cov khoom lag luam siab.
