1. ** Dab tsi yog astm 138 khoom? **
ASTM A178 yog qhov tshwj xeeb rau ** hluav taws xob {}} {}}}}} manganese steel boiler thiab tus supertheat voos **. Cov raj no feem ntau siv nyob rau hauv ** Rauv phab ntsa, boilers, thiab superheaters * Qhov twg muaj qhov hloov cua sov. Qib nyoog tseem ceeb nyob rau hauv cov kev qhia no suav nrog A178 qib A (Carbon {{manganese steel), thiab qib carbon}} manganese hlau).
2. ** Dab tsi yog ASTM rau CS yeeb nkab? **
Muaj ** tsis muaj ib qho ANTM qauv ** rau txhua tus neeg hlau (CS) yeeb nkab. Tus qauv tsim nyog nyob ntawm qhov ** Xav siv, kev pabcuam, thiab kev tsim qauv **. Hom thiab tseem ceeb Astm cov qauv rau cov yeeb nkab steel muaj xws li:
* ** A53: ** XEEM Seamless thiab Welded Dub thiab Kub- dipped galvanized steel yeeb thiab cov qib (ib txwm muaj: a, b).
* ** A106: ** Npog Seamless Cov Hlau Yeeb Nkab Rau Siab- Cov Kawm Kub (Cov Qib Ib: A, B, C).
* ** A333: ** XEEM Seamless thiab Welded Carbon thiab Alloy Steel Yeeb Nkab Rau Tsawg-}} kub kev pab.
* ** A134 & A135: ** Npog hluav taws xob - fusion (arc) {welded steel yeeb nkab loj tshaj plaws nps 16 thiab tshaj saud.
* ** A139: ** Npog hluav taws xob - fusion (arc) {2 {welded steel yeeb nkab nps 4 thiab tshaj.
* ** A252: ** Npog cov yeeb nkab welded thiab seamless steel hlau piles.
* ** A589: ** DOV NPOG DEAMLESS thiab Welded Carbon Steel Yeeb Rau Dej Zoo.
* ** A795: ** Npog dub thiab kub- dipped galvanized welded thiab seamless steel yeeb nkab welrinkler cov tshuab hluav taws xob.
3. ** Qib kawm yog qib CS Seamless yeeb nkab? **
Carbon Steel seamless yeeb nkab los ntawm ** ntau qib **, txhais los ntawm cov qauv ATM tshwj xeeb nws ua tau. Cov qhab nia feem ntau rau General siab thiab siab - kub kev pab yog:
* ** ASTM A53 Qib A53 Qib B: ** Siv dav rau cov ntawv thov General siab, tshuab, thiab siv cov qauv teeb tsa.
* ** ASTM A106 Qib B: ** Feem ntau cov qib rau seamless yeeb nkab hauv high {1} cov nroj tsuag kub (piv txwv li cov khoom siv hluav taws xob, ua kom cov piping). Lwm qib zoo li A106 Qib A (lub zog qis) thiab qib C (siab dua) kuj muaj.
* ** AVTM A333 Qib 6: ** Siv rau Seamless Yeeb Yeeb Yam Yuav Tsum Muaj Kev Cuam Tshuam Cov Khaub Ncaws Zoo ntawm Tsawg Kub.
4. ** Dab tsi yog qhov sib txawv ntawm qib A thiab qib B Carbon Steel? **
(Tshwj xeeb piv cov qhab nia zoo li ASTM A53 / A106 GR A VS Gr B)
* ** Lub zog: ** Qib B muaj ** ntau dua qhov tsis tshua muaj zog thiab tawm lub zog dua qib A. Qhov no ua rau qib B cov pa dej muaj zog dua thiab muaj peev xwm tiv thaiv ntau dua.
* ** QIB TSHUAJ: ** Qib B feem ntau tso cai rau me ntsis cov pa roj carbon (c) thiab manganese (mn) ** cov ntsiab lus dua qib A. Qhov no pab nws lub zog dua.
* ** Tus nqi / muaj: ** Qib B yog tus ** feem ntau siv thiab npaj txhij ** qib rau cov ntawv thov siab. Qeb A yog qhov tsawg dua thiab qee zaum kim dua vim muaj kev xav tau qis dua, txawm tias muaj peev xwm muaj cov nqi qis me me.
* ** Daim ntawv thov: ** Qib b yog qhov kev xaiv rau kev xaiv siab rau cov kav dej siab ** cov tshuab vim nws lub zog siab dua. Qeb ib qho yuav siv tau qhov twg qis zog yog tau los yog rau cov ntawv thov kev siv.
5. ** Dab tsi yog cs b steel qib? **
"CS B" feem ntau yog hais txog ** ASTM A106 Qib B ** lossis ** ASTM A53 Qib B **.
* Nws kos npe rau ** Carbon steel yeeb nkab ntsib cov cai ntawm qib b ** nyob rau hauv cov qauv ASTM.
* ** ASTM A106 qib b ** yog cov kev tshwj xeeb tshaj plaws rau ** Seamless Cov Kev Pab Cuam Steel siv rau hauv cov nroj tsuag hluav taws xob, cov txheej txheem ntawm cov nroj tsuag hluav taws xob, cov nroj tsuag). Nws muaj kev sib npaug ntawm lub zog, weldability, thiab formability.
* ** ASTM A53 Qib B ** npo ob ** Thaum seamless yeeb nkab tau muab rau A53 Gr B, nws muaj qhov zoo sib xws (txawm hais tias tsis zoo tib yam) cov khoom rau A106 Gr B Yeeb.
* Hauv essence, "feem ntau B" feem ntau txhais tau tias yog ob qho yeeb nkab roj teeb lub siab **, feem ntau cuam tshuam kev kub siab {}} rated yeeb nkab haum rau kev pabcuam.
