** 1. Dab tsi yog ASTM A213 khoom siv? **
ASTM A213 qhia txog cov neeg siv hluav taws xob uas tsis sib xws boiles, thiab cov kev pab kub kub uas tsim rau kev pabcuam kub. Cov qib kawm muaj xws li T11, T22, T91 (Ferritic), thiab TPTP36 (Austenitic). Cov hlab yog siv nyob rau hauv ib puag ncig uas xav tau corrosion tsis kam, siab lub zog, thiab durability nyob rau hauv siab kub thiab pressures.
** 2. Dab tsi yog qhov kev pheej hmoo ntawm ASTM A213? **
Kev thev xim ASTM A213 yaj xws li:
- ** Sab nraum lub taub (OD): ** Feem ntau 0. 5% ntawm tsab cai OD lossis {}. 010 nti (saib qhov twg yog dua).
- ** Phab ntsa tuab: ** Feem ntau ± 10% ntawm Nominal Thickness.
- ** Ntev: ** ± 1\/8 nti rau qhov ntev tsawg dua lossis sib npaug rau 20 feet, lossis pom zoo ntawm tus xa khoom thiab yuav khoom.
- ** Ruralness: ** Sib txawv los ntawm qhov loj me (piv txwv li, 0. 001 nti ib nti ntev).
Ntev ua kom muaj kev zam rau ntawm lub raj ntev thiab qib; Xa mus rau tus qauv rau cov lus qhia tshwj xeeb.
** 3. Dab tsi yog qhov sib txawv ntawm Astm A335 thiab A213? **
- ** SHTM A213: ** XAIV SEAMLESS ** RAU BOILERS ** RAU BOILERS, superheaters, thiab kev hloov pauv kub.
- ** SHTM A335: ** Qhia tawm seamless ferritic alloy-steel ** rau kev pab kub (piv txwv li, cov tshuab raj).
Qhov sib txawv tseem ceeb:
- ** Daim ntawv thov: ** QUBES (A213) thiab cov kav dej (A335).
- ** KAWM: ** A213 siv "qib (piv txwv li T11), thaum A335 siv" qib P "(piv txwv li, P11).
- ** Cov qauv seem: ** Cov raj muaj cov qauv stricterd od \/ kev ua siab ntev yuav tsum muaj rau cov ntawv thov kub-hloov cua sov.
** 4. Dab tsi yog qhov sib txawv ntawm Astm A213 thiab A269? **
- ** ASTM A213: ** Seamless Alloy-Hlau (Ferritic \/ Austenitic) Hles rau Kev Pabcuam Kub Kub.
- ** ASTM A269: ** RETODED ** WELDED THIAB DEAMLESS ** AUSTENITIC COV NTAUB NTAWV COLLOSION-RESIONS (TSIS TXAUS SIAB RAU QHOV CUA LI CAS).
Qhov sib txawv tseem ceeb:
- ** Cov ntaub ntawv tau hais tias: ** A213 suav nrog cov hlau nplaum alloy; A269 tsom rau cov hlau tsis muaj roj.
- ** Kev tsim khoom: ** A269 tso cai welded leeg; A213 yog seamless nkaus xwb.
- ** Daim ntawv thov: ** A213 rau boilers \/ tshav kub hloov; A269 rau qis-kub, kev xeb ib puag ncig.
** 5. Dab tsi yog qhov sib txawv ntawm Astm thiab Ams specs? **
- ** ASTM (American Society rau kev sim thiab cov qauv): ** Cov khoom lag luam dav rau cov khoom, cov khoom lag luam, thiab cov tshuab nyob thoob plaws (kev tsim kho, thiab lwm yam). Tsom rau kev ua tau zoo, kev nyab xeeb, thiab xwm yeem.
- ** Ams (Aerospace Cov Khoom Siv Tshwj Xeeb): ** Ib qho ntawm SAE (SAE International) cov qauv tshwj xeeb rau Aerospace. Xws li txoj kev nruj yuav tsum tau rau cov ntaub ntawv (cov hlau, cov tshuaj sib xyaw, sib xyaw) siv hauv kev ua kom muaj kev sib xyaw \/ chaw, kev sim siab, kev sim tshuaj, thiab huab.
** Qhov sib txawv tseem ceeb: ** ASTM yog dav dav-lub hom phiaj, thaum Ams yog tshwj xeeb rau Aerospace nrog kev tswj hwm kev hloov kho thiab siab dua.
