ASTM A213 Seamless Stainless Boiler Tube yog tsim los siv cov qib austenitic stainless hlau -xws li TP304H, TP316L, thiab TP347H- thiab tau txais kev kho mob thiab kev kho mob passivation. Cov hlab no muaj kev tiv thaiv corrosion zoo heev, muaj peev xwm tiv taus cov teebmeem corrosive ntawm cov xov xwm xws li chav, condensate, thiab flue gas hauv lub tshuab hluav taws xob.
Lub raj yog raug rau precision txias kos duab, ua rau sab nraud txoj kab uas hla ntawm Less tshaj los yog sib npaug rau ± 0.05 hli thiab phab ntsa thickness kam rau ua tsawg dua los yog sib npaug rau ± 10%. Piv nrog rau cov pa roj carbon steel raj-xws li cov ntawv teev tseg hauv ASTM A192 lossis ASTM A210-ASTM A213 stainless hlau tuav lub zog zoo tshaj plaws ntawm qhov kub siab, nrog rau qib TP347H muaj peev xwm tiv taus qhov kub txog li 700 degree.

Cov qhab nia xaiv tau
- Rau supercritical thiab ultra-supercritical thermal power units ua haujlwm ntawm qhov kub ntawm 600℃lossis siab dua, T92 thiab TP317L yog qhov kev xaiv tsim nyog.
- Rau cov pa nruab nrab-kub, nruab nrab-siab thermal fais fab units, T22 thiab TP304 raug pom zoo rau lawv cov nqi zoo heev -effectiveness.
- TP347HFG qhia oxidation- nplai spalling tsis kam nyob rau hauv siab - qhov kub thiab txias (580-620 degree) uas yog deb tshaj li ntawm TP347H, yog li zoo tiv thaiv scale -induced blockages.

FAQ
Q: Qhov ntsuas kub thiab siab npaum li cas yog ASTM A213 seamless stainless hlau boiler raj tsim nyog rau hauv lub zog tsim hluav taws xob?
A: ASTM A213 seamless stainless boiler raj feem ntau yog siv nyob rau hauv lub zog tsim los ntawm -20℃mus rau 800℃thiab 0.1 MPa rau 30 MPa, nyob ntawm seb qib xaiv thiab cov kev pab cuam tej yam kev mob.
Q: Vim li cas TP304 tsis siv, thiab TP304H nyiam dua?
A: TP304 muaj tsawg dua los yog sib npaug rau 0.08% carbon thiab tsis ua kom zoo rau ntev -lub sij hawm siab - kub creep kuj. TP304H tau tswj cov pa roj carbon ntau dua (0.04–0.10%), txhim kho siab - qhov kub thiab txias thiab ua rau nws haum rau chav ua haujlwm siab tshaj ~ 550℃.
Q: Puas yog kev sim hydrostatic thiab tsis yog - kuaj kev puas tsuaj ua ntej xa khoom?
A: Yog. Tag nrho cov raj tau txais 100% hydrostatic testing, nrog rau eddy tam sim no kuaj (ECT) thiab ultrasonic kuaj (UT), kom paub tseeb tias tsis muaj leaks los yog sab hauv tsis xws luag ua ntej xa zaub mov.
