High Residual Phosphorus UNS C12200 yog dab tsi?
C12200 tooj liab, tseem hu ua alloy 122 deoxidized siab -phosphorus (DHP) tooj liab, yog ib qho ntawm ntau cov hlau tsis muaj hlau uas peb muab ntawm no ntawm GNEE. Raws li lub npe qhia, qhov kev lag luam ntshiab tooj liab tau dhau los ua phosphorus deoxidation los txhim kho nws cov khoom siv. Tshwj xeeb tshaj yog, cov phosphorus residual cov txheej txheem tawm tom qab ua rau C12200 zoo tagnrho rau hnyav- daim ntawv thov, qiv nws nce corrosion kuj thiab compatibility nrog vuam thiab brazing txheej txheem. Tsis tas li ntawd, cov khoom siv tsis yog hluav taws xob heev lossis ua rau hydrogen embrittlement.
Qhov "High Residual Phosphorus" txhais li cas?
Yuav kom nkag siab txog C12200, koj yuav tsum paub me ntsis txog kev ua tooj liab li cas. Thaum tooj liab yog refined thiab cam khwb cia, oxygen tuaj yeem nkag rau hauv cov khoom. Rau feem ntau cov ntawv thov hluav taws xob, qhov ntawd tsis yog qhov teeb meem loj. Tab sis rau lub raj thiab cov yeeb nkab uas yuav welded los yog brazed, oxygen yog ib qho teeb meem. Nws tuaj yeem ua rau embrittlement thaum raug hydrogen thaum lub sij hawm koom nrog- tshwm sim hu ua "hydrogen embrittlement."
Deoxidized tooj liab daws qhov no los ntawm kev ntxiv me me ntawm phosphorus thaum ua. Cov phosphorus reacts nrog cov pa oxygen ntxiv, zoo "tu" cov tooj liab ua ntej nws tsim rau hauv raj. Qhov "siab residual" txhais tau hais tias ib qho me me ntawm phosphorus tseem nyob hauv cov khoom kawg, feem ntau ntawm 0.015% thiab 0.040%. Qhov seem phosphorus yog dab tsi muab C12200 nws qhov zoo sib xws hauv kev tsim.

Dab tsi yog Cov Txheej Txheem Tempers thiab Muaj Cov Ntawv?
C12200 tooj liab raj feem ntau muaj nyob rau hauv kos (nyuaj) thiab annealed (mos) tempers. Qhov kev xaiv yog nyob ntawm koj txoj kev teeb tsa:
Annealed (mos) temper: Muab nyob rau hauv coils. Qhov no yog qhov koj siv rau kev khiav ntev uas koj yuav tsum tau khoov lub raj ncig ntawm qhov thaiv. Feem ntau hauv cov kav dej hauv vaj tse, cov cua kub cua sov, thiab cov tub yees kab.
Drawn (nyuaj) temper: Muab nyob rau hauv ncaj lengths. Siv rau kev lag luam piping tshuab qhov twg lub raj yog ntsia ncaj nraim nrog fittings ntawm kev hloov hauv kev coj.
Tshaj lub raj, C12200 kuj muaj raws li cov yeeb nkab (hauv cov phab ntsa hnyav dua rau kev siv siab), fittings, thiab kev cai- cov khoom tsim. Yog tias koj ua haujlwm nrog cov chaw tsim khoom lag luam uas ua kev cai tooj liab fabrication - khoov, headers, manifolds -C12200 feem ntau yog cov khoom siv vim nws welds thiab brazes kom huv si.
FAQ
Puas yog C12200 tib yam li DHP tooj liab?
Yog lawm. DHP sawv cev rau Deoxidized High Residual Phosphorus, uas yog raws nraim li UNS C12200 yog. Koj yuav pom ob nqe lus siv sib pauv hauv cov lus qhia tshwj xeeb thiab cov ntaub ntawv cov khoom lag luam.
C12200 puas tuaj yeem welded, lossis yog brazing tib txoj kev xaiv?
C12200 tuaj yeem welded, tab sis brazing thiab soldering yog ntau dua. Yog tias koj xav tau welded tooj liab, C12200 tuaj yeem TIG welded nrog txoj cai muab tub lim hlau. Txawm li cas los xij, rau feem ntau cov ntawv thov, brazing nrog phosphorus - tooj liab lossis nyiaj -brazing alloy yog tus qauv kev sib koom ua ke.
Cov ntsiab lus phosphorus puas cuam tshuam rau thermal conductivity?
Me ntsis. C12200 muaj marginally qis thermal conductivity tshaj cov qib tooj liab ntshiab xws li C11000, tab sis qhov sib txawv yog negligible rau cov kav dej, HVAC, thiab cov ntawv siv hluav taws xob. Koj yuav tsis pom muaj kev cuam tshuam txog kev ua haujlwm hauv tiag tiag - ntiaj teb kev teeb tsa.
Puas yog C12200 kim dua li cov qauv tooj liab?
Feem ntau, C12200 yog tus qauv. Nws yog qhov koj yuav pom ntawm lub txee ntawm cov khoom siv feem ntau. Yog tias muaj dab tsi, cov qib tshwj xeeb xws li C10200 tseem kim dua. Rau cov kav dej ib txwm thiab HVAC ua haujlwm, C12200 yog lub hauv paus, tsis yog kev hloov kho hwm.
Dab tsi yog qhov siab tshaj plaws ua haujlwm kub rau C12200 raj?
Hauv kev siv cov kav dej siab, qhov tso cai ua haujlwm siab txo qis thaum kub nce. Rau feem ntau cov kev pabcuam hauv tsev, C12200 yog qhov tsim nyog txog li ntawm 250℃F rau kev pabcuam txuas ntxiv. Rau siab dua - kub daim ntawv thov xws li chav dej lossis siab - siab boilers, koj yuav tsum sab laj nrog cov txheej txheem siab piping code thiab xav txog phab ntsa thickness raws li.
