Taw qhia
Kab lus no piav qhia vim li cas C12000 yog phosphorus -deoxidized tooj liab. C12000 yog DLP qib ntawm phosphorus-deoxidized tooj liab, qhov twg DLP sawv cev rau deoxidized tsawg phosphorus. Nws yog cov khoom siv rau cov raj dej tooj liab, ACR raj thiab cov raj xa hluav taws xob vim tias cov phosphorus tshem tawm cov pa tawm ntawm cov yaj thiab ua rau cov hlau muaj kev ruaj ntseg rau braze, weld thiab ci-anneal.
Kev sib xyaw thiab Qib Identity
C12000 muaj tsawg kawg yog 99.90 feem pua tooj liab nrog phosphorus residual ntawm 0.004 txog 0.012 feem pua. Nws yog ib qho tseem ceeb kom paub qhov txawv ntawm DLP los ntawm DHP: DHP qib C12200 yog siab dua phosphorus ntau ntawm 0.015 mus rau 0.040 feem pua thiab ib tug me ntsis conductivity ntawm 85 feem pua IACS, thaum C12000 DLP khaws cia roughly 90 mus rau 95 feem pua IACS. Suav sib npaug ntawm cov khoom qis-phosphorus yog TP1, thiab qhov siab dua -phosphorus khoom yog TP2, nrog rau ob qho tib si txhais hauv GB/T 5231.
Yog vim li cas phosphorus ntxiv
Phosphorus ua raws li deoxidizer thaum yaj. Nws ua ke nrog cov pa oxygen hauv cov yaj kom cov hlau cam tsis muaj cuprous oxide. Yog tias tsis muaj oxide nyob rau ntawm cov ciam teb, cov tooj liab tsis tuaj yeem raug kev txom nyem hydrogen embrittlement thaum lub sij hawm brazing los yog vuam, uas yog vim li cas deoxidized qib yuav tsum tau koom nrog cov raj hauv cov kav dej, cua txias thiab kev sib hloov cua sov.
| Khoom | C12000 DLP | C12200 DHP |
|---|---|---|
| Phosphorus | 0.004 - 0.012% | 0.015 - 0.040% |
| Kev coj ua | 90 - 95% IACS | Txog 85% IACS |
| tooj liab min | 99.90% | 99.90% |
| Suav qib | TP 1 | TP 2 |
Cov cuab yeej thiab tus cwj pwm ua haujlwm
DLP tooj liab raj muaj cov thermal conductivity zoo, siab ductility, thiab zoo heev khoov, flaring thiab nthuav tus cwj pwm, uas tso cai rau txhim khu kev qha swaged thiab brazed pob qij txha. Nws yog tsim nyob rau hauv kos tempers nrog lub zog nyob ntawm seb lub℃ntawm txias ua hauj lwm, thiab nws teb kwv yees rau annealing. Cov khoom siv kuj muaj kev tiv thaiv corrosion zoo hauv dej tshiab, dej hiav txwv thiab ntau yam tshuaj lom neeg.
Daim ntawv thov
Cov kev siv feem ntau yog cov kav dej kav dej, boiler thiab condenser tubing, ACR raj rau tub yees thiab cua txias, roj txias, cua kub exchanger raj thiab dav engineering raj. Cov qib yog muaj raws li lub raj ncaj thiab coil, thiab nws tau them los ntawm ASTM B75, B88, B280 thiab B68 raws li cov khoom lag luam.
Kev lees paub thiab kev yuav khoom
Paub meej txog phosphorus ntau, conductivity, temper thiab qhov ntev ntawm qhov kev txiav txim, thiab xyuas cov ntawv pov thawj zeb tawm tsam tus qauv tsim nyog. Rau cov ntawv thov siab, tshawb xyuas qhov yuav tsum tau kuaj hydrostatic thiab lub raj tso cai ua ntej txais.
