ASME SA213 TP444 Stainless Hlau Seamless Tube Rau Cov Hluav Taws Xob Kub

ASME SA213 TP444 yog Ferritic Stainless Hlau Seamless Yeeb Nkab xws li tshav kub kub, high {} thiab superheaters vim nws zoo corrosion tsis kam. Nws muaj pes tsawg leeg, suav nrog molybdenum, nitrogen, thiab tooj liab, ua rau nws xaiv qhov zoo tshaj plaws rau cov petrochemical, kev ua haujlwm zoo, tshuaj lom neeg ua lag luam. Thaum siv ASME sa213 TP444 seamless stainless hlau yeeb nkab tsim kom tsis txhob muaj qhov tseeb ntawm 370-540℃yuav tsum tau ua raws li lub sijhawm vuam thiab ua haujlwm txias.

 

ASME sa213 Seamless stainless hlau yeeb tuaj yeem raug kho kom tau raws li cov neeg siv khoom tshwj xeeb, thiab kev kho cua sov, kom tau raws li cov ntawv thov kub ntxiv. Feem ntau, ASME SA213 seamless stainless hlau yeeb nkab muaj nyob rau hauv ntau thiab tsawg nyob rau hauv 1/2-nti mus rau 8-nti mus rau tam sim no ASTM, API, thiab ASME Cov Qauv.

Gnee yog cov chaw tsim khoom lag luam thiab cov khoom lag luam ntawm ASTM A213 Seamless kav dej, muaj peev xwm ua ntau yam rau cov cua sov. Cov txheej txheem tsim khoom pib nrog cov xuv nyiaj, uas yog tom qab ntawd muab cov khaub noom txias thiab kos kom tswj qhov ntev thiab thev taus. Tom qab ua haujlwm txias, cov hlau yog cov khoom siv kub ua kom tiav nws cov khoom qub, txhim kho nws qhov siab- kub thiab corrosion tsis kam. Cov kav dej yog li pickled thiab passivated.
