C122 {{0 0 yog ib qho siab-phosphorus distension thiab 0.015% {}. 040% {4}} Nws yog dav siv nyob rau hauv kev tsim khoom piping, cua sov, cua txias (hvac) tshuab thiab ua rau vuam muag lossis raug rau kev siv vuam.
Cov hauv qab no yog qhov ntsuas ntau seem:
1. Hom thiab Txuj Ci
ASTM Txuj Ci: C12200 (ASTM B152 \/ B133), Categorized Deagphorus deoxidized Tooj Liab (DHP tooj liab), sib raug rau tsis ua tiav No. C12200.
Kev Ntsuas Txoj Kev: TP2 (GB \/ T {1}}}, phosphorus cov ntsiab lus {2} {4}}. 040%).
Kev sib piv thoob ntiaj teb:
EN: CU-DHP (EN 1652, phosphorus cov ntsiab lus ntsuag {2}}. 013% {4}}. 050%);
JIS: C122 {{{0 (0.015% -0. 040% phosphorus cov ntsiab lus);
DIN: CU-DHP (DIN 17650).
2. Tshuaj lom neeg sib xyaw
Cov ntsiab lus piav qhia ntau yam
Tooj liab (Cu) ntau dua los yog sib npaug rau 99.85% MATRIX, hom hluav taws xob \/ thermal conductivity
Phosphorus (p) 0. 015% -0. 040% muaj zog deoxidization, txhim kho hydrogen embrittlement thiab corrosion tsis kam
Oxygen (O) tsawg dua lossis sib npaug ntawm 0. 007% seem oxygen yog txo ntxiv kom tsis txhob muaj thaj tsam nplej.
Lwm cov impurities tsawg dua los yog sib npaug rau 0. 15% (piv txwv li kev tswj hwm nruj me ntsis kom ntseeg tau tias cov khoom siv.
3. Cov khoom tseem ceeb
Corrosion Kuj:
Anti-dezincification corrosion (dej hiav txwv ib puag ncig corrosion yog 50% qis dua tooj liab);
Kev ntxhov siab corrosion cracking (SCC) tsis kam yog muaj zog heev, haum rau kev kub siab xa xov siab.
Conductivity:
Annealed State: Loj dua los yog sib npaug rau 96% IACS (Phosphorus muaj cov txiaj ntsig tswj hwm ntawm kev ua haujlwm);
Txias ua haujlwm lub xeev: Kev tsim txom tsawg dua los ntawm kwv yees li 3% {2}}% (tseem tuav ntau dua lossis sib npaug ntawm 92% IRCS).
Kev Ua Tau Zoo:
Txias zog rolled deformation tus nqi txog li 70% tsis muaj kev tawg, haum rau kev sib sib zog nqus thiab cov yeeb nkab dabtsi yog khoov;
Zoo heev Vuam kev ua tiav (Brazing, Tig Vuam tsis muaj kev kho kom zoo ntxiv).
Cov Khoom Siv Neeg Kho Tshuab:
Annealed State: tensile zog 220-260 mpa mpa, elongation ntau dua los yog sib npaug rau 35%;
Lub xeev nyuaj: tensile zog 400-480 mpa mpa mpa mpa kom ntau dua lossis sib npaug rau 60%).
4. Sib piv nrog cov tooj zoo sib xws phosphorus tooj liab (C12200 VS C11700)
Cov yam ntxwv C12200 (Astm High Phosphorus) C11700 (ASTM cov pa phosphorus)
Phosphorus cov ntsiab lus {{{{{4 {}}}}. 015% {} {6}}. 040% (tib yam)
Cov pa oxygen seem tsawg dua los yog sib npaug rau {{0}}}}}}}}}}}.} Tsawg dua los yog sib npaug 0.005%
Corrosion Kuj Zoo Tshaj Plaws (Siab Phosphorus inhibits Cov Hmoov nplej Conrosion) zoo
Cov ntawv thov neeg raug cia siab tias cov kav dej tsis zoo, roj li qub tsev vov tsev, cua sov compressaigh pa luam
5. Thaj chaw ntawm daim ntawv thov
Cov Tshuab Luam Nruab:
Tsev cov kav dej kub thiab dej txias (ASTM B88 qauv, siab tsis kam ntau dua lossis sib npaug rau 2.5 MPA);
Ship seawater cooling pipes (salt spray corrosion resistance life>20 xyoo).
Cua sov, dim pa thiab cua txias (HVAC):
Tub yees thauj tub rog (freon corrosion tsis kam);
Kev ua kom sov hloov ua haujlwm raj (kev ua tau zoo tshaj plaws crazing).
Tshuaj lom neeg tshuaj:
Natural Roj Siab Txo Valve Lub Cev (tiv taus hydrogen sulfide corrosion);
Geothermal zoo casing casing (tiv taus rau corrosion los ntawm cov dej kub siab geothermal).
Hniav Engineering:
Antique tooj liab vuas (nto oxidation kev kho mob uas qhia tau cov txiaj ntsig ntsuab ntsuab);
Kos duab Casting Qhov Chaw (siab phosphorus txhawm rau txhim kho fluing fluacity).
