Dec 04, 2025
Dab tsi yog cov khoom ntawm A335 Pipe
ASTM A335 Cov Lus Qhia Tshwj Xeebyog seamless ferritic chromium -molybdenum alloy hlau. ASTM A335 / A335M tus qauv npog ntau qib ferritic alloy steel, suav nrogP1, P2, P5, P5B, P5C, P9, P11, P12, P21, P22, P23, P36, P91 (Hom 1, Hom 2), P92, thiab lwm yam. Cov kav dej muaj ib qhoSab nraud txoj kab uas hla ntawm 21.3 hli mus rau 762 hlithiab aphab ntsa thickness ntau ntawm 2.0 hli mus rau 130 hli, tsim los ua kom tau raws li qhov yuav tsum tau muaj rau ntau haiv neeg siab -cov kav dej kub.
