### 1. Dab tsi yog cov pa roj carbon steel?
Cov pa roj carbon ntau yog ib hom tshuaj carbon nrog cov ntsiab lus roj carbon monoxide xws li 0.60% txog 1.0%. Qhov no cov ntsiab lus carbon siab no ua rau nws nyuaj thiab muaj zog, tab sis nws tseem txo nws lub zog, ua nws nkig ntau thiab haum rau vuam. Cov pa roj carbon ntau yog feem ntau siv rau cov ntawv thov uas muaj kev tawv tawv, xws li hauv cov cuab yeej, siab} lub zog xov hlau, thiab tuaj. Nws tsis yog feem ntau siv rau cov tshuab luam ntawv.
### 2. Dab tsi yog cov yeeb nkab roj carbon hlau siv rau?
Cov yeeb nkab steel yog ib qho ntawm cov khoom siv dav siv rau cov dej sib txuas, roj av, thiab slurries thoob plaws ntau yam lag luam. Nws thawj cov kev siv suav nrog:
* ** Cov roj thiab roj kev lag luam: ** Rau kev sib sau, kis tau, xa khoom, thiab xa xov tuaj, ob leeg onshore thiab sab caj dab.
* ** Cov nroj tsuag fais fab: ** Rau kev thauj cov chav, condensate, thiab cov khoom qab zib.
* ** Daim ntawv thov kev tsim kho tshiab: ** Raws li scaffolding thiab rau cov qauv kev txhawb nqa hauv cov tuam tsev.
* ** DEJ thiab dej phwj dej: ** Rau cov dej hauv nroog thiab dej khib nyiab.
* ** Kev lag luam Industrial: ** Hauv cov nroj tsuag tshuaj lom neeg, ua kom zoo dua thiab tsim chaw tsim khoom kom txav cov kua dej thiab huab cua.
### 3. Dab tsi yog qib yog cov yeeb nkab roj carbon hlau?
Cov pa roj carbon cov hlau tuaj hauv ob peb qib tau hais los ntawm cov koom haum qauv zoo li ASTM (American Society rau kev sim thiab cov ntaub ntawv). Cov qhab nia feem ntau rau kev pabcuam dav dav thiab siab -} sov daim ntawv thov yog:
* ** ASTM A106 Qib B: ** Qhov no yog feem ntau ntawm cov qib rau siab-} pa taws thiab cov txheej txheem kev lag luam). Nws muaj lub kaum ntau dua thiab tawm zog tshaj qhov qib A.
* ** ASTM A53 Qib A53 Qib B: ** Cov ntawv thov siab ntau thiab kev siv zog, nrog rau Chav, dej, thiab huab cua. Nws zoo ib yam li A106 B tab sis tseem muaj raws li ERW (hluav taws xob tiv thaiv welded) yeeb nkab.
Lwm qib kawm suav nrog ANTM A106 qib A (qis dua C (qib API zoo li qib B thiab X42-X80 rau roj thiab roj kev kis thiab siv roj.
### 4. Yuav ua li cas CS cov yeeb nkab txhais tau?
** CS cov yeeb nkab ** yog ib qho lus luv rau ** cov yeeb nkab steel roj steel **. Nws yog ib lo lus dav dav siv los paub qhov txawv kav hlau thiab carbon los ntawm cov ntaub ntawv xws li stainless hlau (SS), HDPE), lossis tooj liab.
### 5. Dab tsi yog qhov sib txawv ntawm CS thiab SS PIPES?
Qhov tseem ceeb ntawm cov roj carbon steel (cs) thiab stainless hlau thiab stainless hlau (SS) nyob hauv lawv cov tshuaj muaj pes tsawg leeg tshuaj thiab, yog li, lawv cov peev txheej.
* ** COLDOSITION THIAB Corrosion Kuj: ** CS feem ntau cov hlau thiab carbon, uas ua rau nws raug rau xeb thiab xeb thaum dej noo thiab huab cua. SS muaj tsawg kawg ntawm 10.5% chromium, uas ua rau ib txheej heavitive, ua rau nws tiv taus corrosion thiab staining.
* ** Lub zog thiab hardness: ** Feem ntau, carbon hlau yuav muaj zog thiab nyuaj dua qee qib ntawm stainless hlau, tshwj xeeb tshaj yog nyob rau hauv nws cov cua sov {0}- Kho cov ntawv.
* ** Tus nqi: ** Carbon Steel yog tsawg dua li kav hlau tsis kim heev, ua rau nws xaiv lub neej ntawd, tsis yog kev txhawj xeeb tseem ceeb.
* ** Daim ntaub ntawv: ** CS yog siv rau cov qauv, thiab kev siv cov khoom siv tsis yog corrosive (piv txwv li cov roj av, roj, dej). SS SS nyob qhov twg corrosion tsis kam thiab kev tu neeg yog qhov tseem ceeb, xws li hauv kev ua lag luam tshuaj, khoom noj thiab dej haus, chaw kho mob marine.
* ** Pom zoo: ** CS muaj qhov tsaus ntuj, Matte tsos thiab yuav xeb yog tias tsis yog suav, thaum ss feem ntau ci, thiab tswj nws cov ntsej muag.
