1. ** Dab tsi yog astm A234 WP22 khoom siv? **
** ASTM A234 WP22 ** Yog ** chromium-molybdenum alloy steel hlau ** siv rau cov pob tw-vuam yeeb nkab-vuam, Tees, lub kaus mom). Nws muaj kwv yees li ntawm ** 2.25% chromium thiab 1% molybdenum **, muab cov khoom siv txhim kho thiab txhim kho corrosion (txog ~ 593 degree \/ 1100 degree f). Nws yog qhov ua kom zoo, tempered, lossis annealed rau kev ua kom zoo microstructure thiab yog feem ntau siv nyob rau hauv qhov kev siv kub-siab \/ lub siab zoo li cov nroj tsuag hluav taws xob thiab cov khoom siv hluav taws xob zoo li cov nroj tsuag hluav taws xob.
2. ** Dab tsi yog sa 234 wpb khoom? **
** SA 234 wpb ** yog ** carbon steel ** Khoom siv cov khoom siv nyob rau hauv Asme boiler thiab siab}} ASME version ntawm ASTM A234). "WPB" Tus Tsim "Welded Fittings ntawm Qib B Carbon Hlau **. Nws muaj qhov tsawg kawg tensile lub zog ntawm 415 mpa (60 ksi) thiab paib lub zog ntawm 240 mpa (35 ksi). WPB fittings yog siv nyob rau hauv kev ntsuas kub-nruab nrab (txog ~ 343 degree \/ 650 degree f) rau cov ntawv thov, thiab cov txheej txheem kev lag luam.
3. ** Dab tsi yog WP22? **
** WP22 ** yog ** yog ** Cov Kev Tsim Cov Khoom Siv ** Raws li ATTM A234 \/ ASME SA234. Tus "** WP **" qhia tias:
- ** w ** {=} weldable fittings.
- ** P ** {= qhov kev pab siab.
- ** 22 ** {=} Alloy alloy Composition: ** 2.25% chromium thiab 1% molybdenum ** (zoo ib yam li istm A335 P22 Yeeb).
Nws yog siv rau fittings xav tau creep lub zog thiab oxidation tiv taus ntawm cov kub.
4. ** Dab tsi yog SA 234 code? **
** SA 234 ** YOG ** ASME BOILER THIAB SIAB RAU LUB HLAU CODE ** BEEDPARTLART ** ASTM A234 **. Nws qhia txog cov tseev kom muaj rau carbon thiab alloy hlau pob tw-vuam fittings siv hauv siab nruab. SA 234 tus qauv ASTTM A234 cov qauv tab sis suav nrog cov cai lij choj uas muaj kev sib koom ua ke thiab muaj cov ntawv thov ua haujlwm (piv txwv li, boilers, siab cov hlab).
5. ** Dab tsi yog WP hauv fittings? **
Hauv cov qauv fittings (piv txwv li, Astm A234 \/ ASME SA234), ** "WP" ** Sawv rau:
- ** w ** {{=}} ** Weldable ** (Haum rau Vuam).
- ** P ** {{=}} siab muaj ** Ntu.
Cov Suffix (piv txwv li, ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** **
- ** ** WPB **: Cov hlau roj carbon (qib b).
- ** WP11 \/ WP22 \/ WP91 **: chromium-molybdenum alloy cov qib.
Piv txwv li: ** WP22 ** {= weldable, siab-siab-siab haum tau los ntawm 2.25cr {{mo steel.
