1. YOG G3429 - Tus Qauv
YOG: Sawv rauIndian Standard, txhais tau tias nws yog ib qho kev qhia tshwj xeeb los ntawm Bureau of Indian Standards (BIS).
G3429: Nov yog tus naj npawb tshwj xeeb. Nws lub npe tag nrho yog:"Steel Tubes rau Boilers, Superheaters, thiab Kub Exchangers".
Lub hom phiaj: Cov qauv no suav nrog cov kev cai rau seamless thiab welded steel raj thiab cov kav dej uas npaj rau siv hauv boilers, superheaters, thiab kub exchangers uas lawv raug rau siab sab hauv thiab kub.
2. STH21 - Qib
STH: Qhov no yog ib tug prefix siv nyob rau hauv tus qauv no, yuav sawv rau"Steel Tube, Thaum tshav kub kub-resisting"los yog tsuas yog ib qho kev faib rau cov qib boiler raj.
21: Tus lej no qhia txog qib tshwj xeeb ntawm carbon steel. Lub "21" sib raug rau cov tshuaj muaj pes tsawg leeg thiab cov khoom siv kho tshuab.
Cov yam ntxwv tseem ceeb ntawm Qib STH21:
Hom: Nws yog aCarbon Steel.
Cov ntsiab lus tseem ceeb - Carbon (C):Nws muaj cov ntsiab lus carbon tsawg, feem ntau nyob ib puag ncig0.17% - 0.23%. Qhov no muab qhov zoo sib npaug ntawm lub zog thiab ductility (formability / weldability).
Manganese (Mn):Feem ntau nyob ib ncig ntawm 0.70% - 1.00%, uas pab ua kom muaj zog.
Lwm Yam Khoom:Nws muaj qib qis ntawm lwm yam alloying ntsiab xws li Silicon (Si), Sulfur (S), thiab Phosphorus (P), uas yog tswj nyob rau hauv cov kev txwv.
Summary of Properties and Applications
| Khoom | Kev piav qhia |
|---|---|
| Txuj | IS G3429 (Indian Standard rau Boiler Tubes) |
| Qib | STH 21 |
| Hom khoom | Carbon Steel |
| Ntsiab Feature | Zoo zog thiab ductility ntawm qhov kub thiab txias. |

Qib sib npaug hauv Lwm Cov Qauv
Yog tias koj tab tom nrhiav khoom thoob ntiaj teb lossis sib piv nrog lwm cov qauv, STH21 zoo ib yam li:
ASTM A192 / ASME SA192 Cov Lus Qhia:Qhov no yog ib qho kev qhia tshwj xeeb hauv Teb Chaws Asmeskas rau siab - siab boiler raj. Cov tshuaj muaj pes tsawg leeg ntawm STH21 yog ze li zoo tib yam rauASTM A192 Qib C.
Qauv TSIS MUAJ: DIN 17175Cov qib zoo sib xws yuav yogib 35.8.
TS EN 10216-2:Cov qib zoo sib xws yuav yogP235GH.
Xaus
yog G3429 STH21qhia aseamless carbon steel yeeb nkabtsim los tiv taus siab thiab kub. Nws yog cov khoom siv ua haujlwm hauv kev tsim kho ntawm:
Cov dej kub boilers
Hluav taws kub boilers
Superheater coils
Ntau hom kev sib hloov cua sov thiab cov hlab ntsha siab
Thaum koj pom qhov kev xaiv no, koj tuaj yeem ntseeg tau tias nws yog hais txog cov yeeb nkab zoo uas yog qhov tseem ceeb rau siab - kub, siab - kev pabcuam siab, ua raws li tus qauv hauv tebchaws Indian.
