1. ** Dab tsi yog asme sa 335 qib P222? **
Asme sa - 335 Qeb P235 Qeb P235 Qeb P235 Qeb P235 Qib P23 yog ib qho yeeb nkab uas tsis muaj tseeb rau qhov siab- kub kev pab. Nws tsim cov kav dej tsim los ntawm cov chromium-molybdenum alloy steel nrog ib tus nominal muaj pes tsawg ntawm 2.25% chromium thiab 1% molybdenum. Cov qib qib no feem ntau siv rau hauv lub zog tiam neeg siv roj, ua kom muaj cov nroj tsuag tsiaj, thiab lwm cov ntawv thov uas muaj kev ntsuas kub thiab ntsuas. Lub "SA" Prefix qhia nws yog ib qho kev paub meej, saws los ntawm lub hauv paus ASTM Txuj (A335) thiab kev sib txuam nrog ntxiv rau kev xav tau (BPVC) yuav tsum tau ua.
2. ** P22 Yeeb Nkab yog dab tsi? **
Cov yeeb nkab p22 yog cov yeeb nkab uas tau ua kom tau raws li cov kev xav tau ntawm cov kev xav tau ntawm cov kev cai tshwj xeeb xws li ASME SA} 335 lossis A335 Qib P22. Nws yog tsim los ntawm cov chromium tshwj xeeb - molybdenum alloy steel (nominal 2.25% rau oxidation thiab nkag mus rau qhov kub thiab txias. P22 pipes are primarily used in critical high-temperature and high-pressure applications, such as steam lines, superheaters, reheaters, and headers in power plants, refineries, and process industries.
3. ** Qib P22 txhais li cas? **
Cov "qib P22" yog hais txog kev sib xyaw ua ke tshwj xeeb thiab teeb tsa cov khoom siv neeg siv hauv A335 / {{{335 specification. Tus "P" sawv rau "yeeb nkab", txawv nws los ntawm cov tub tub (uas yuav siv "T22). Tus lej "22" Keeb kwm sib raug zoo rau Nominal Chromium cov ntsiab lus (kwv yees li 2.25%) thiab cov molybdenum cov ntsiab lus (kwv yees li 1%) hauv alloy. Yog li, qib P22 tshwj xeeb qhia txog qhov qis qis- chromium cov yeeb nkab uas muaj txog 2.25% chromium thiab 1% molybdenum, tsim rau kev pab kub siab.
4. ** Kev ntxhov siab uas tau tso cai rau A335 P22 Yeeb? **
Cov kev ntxhov siab uas tau pub rau A335 P222 yog tsis yog tus nqi tas li; Nws txawv tseem nyob ntawm cov hlau kub. Qhov kev ntxhov siab no tau txhais nyob rau hauv ASME boiler thiab siab vessel code, Tshooj II, cov khoom siv rau kev ntxhov siab ntau tshaj rau cov khoom siv ferrous. Piv txwv li (keeb kwm kev sib piv raws li kev raug BPVC cov ntaub ntawv):
* Ntawm chav sov (100℃f / 38 degree), nws yog kwv yees li, 17.9 ksi (123 MPa) **.
* Thaum 800℃f (427 degree), nws yog kwv yees li ** 7.8 KSI (54 MPA) **.
* Thaum 1000℃f (538 degree), nws yog kwv yees li ** 3.8 ksi (26 MPA) **.
* Thaum 1100℃f (593 degree), nws yog kwv yees li ** 2.0 ksi (14 MPa) **.
* Ntawm 1200℃f (649 degree), nws yog kwv yees li ** 1.1 ksi (7.6 mpa) **.
** CEEB TOOM TSEEM CEEB: ** RAU QHOV TSEEB, koj yuav tsum sab laj qhov tseeb tshaj plaws ntawm ASME BPVC Ntu kev ntxhov siab muaj nuj nqis rau kev tsim tshwj xeeb. Qhov tseem ceeb hloov pauv nrog cov cim kev hloov kho thiab khoom siv cua sov.
5. ** Dab tsi yog TTM A335 khoom siv tshwj xeeb? **
ASTM A335 yog cov hauv paus txheem tshwj xeeb rau kev sib txuas lus rau seamless ferritic alloy {} Cov yeeb nkab steel tsim rau high- kub kev pab. Nws txhais tau cov tshuaj lom neeg muaj pes tsawg leeg, cov tshuaj tiv thaiv lub zog, ua kom muaj zog, p9, P11, P91, thiab lwm yam. ASME Sa - 335 adopts no tl tus qauv tab sis suav nrog cov kev xav tau ntxiv kom nws siv tau rau kev siv hauv asme boiler thiab siab lub siab boiler code kev tsim kho. Cov kav dej ua raws li ASTM A335 feem ntau yog siv hauv cov nroj tsuag hluav taws xob, ua kom zoo nkauj, thiab tshuaj chemical rau cov ntawv thov hnyav / siab.
