Cov qib qis-kub carbon steel yeeb nkab qib suav nrogTom ntej: ASTM A333 Gr.1, A333 Gr.3, A333 Gr.6, uas sawv cev rau cov khoom siv sib txawv thiab cov kev ua haujlwm tsis zoo kom ua tau raws li ntau yam tsawg - qhov yuav tsum tau siv kub. Piv txwv li,ASTM A333 Gr.6tuav zoo toughness thiab lub zog ntawm qhov kub tsis tshua muaj siab, ua rau nws tsim nyog rau kev thauj mus los hauv cov kav dej hauv qhov chaw txias txias.
Tsis tas li ntawd, cov qauv hauv tsev rau qis -kub carbon steel kav suav nrogQ345B/C/D/E, 09MnD, 09MnNiD, 16MnDG, uas tseem tuaj yeem ua tau zoo heev hauv qhov chaw qis - qhov kub thiab txias thiab tau siv dav hauv kev lag luam petrochemical thiab tub yees.
Cov yam ntxwv tseem ceeb ntawm ASTM A333 Qib
ASTM A333 Gr.6: A npib tsib xee -dawb low-kub steel nrog nplua-grained ferrite microstructure, feem ntau xa hauv normalized lossis normalized + tempered mob .
ASTM A333 Gr.3: Zoo ib yam li Gr.6 tab sis nrog cov tshuaj sib txawv me ntsis, kuj tsim nyog rau kev siv cryogenic.
ASTM A333 Gr.1: Ib qho dav dav - hom phiaj qib rau qis- kev pabcuam kub nrog cov kev xav tau yooj yim.
Cov qauv hauv tsev (GB / T)
09 MnNiD/16 MnDG: Ntimnpib tsib xee (Ni)txhawm rau txhim kho qis -kub toughness, zoo tagnrho rauLNG cia tanksthiabcryogenic pipelines.
Q345 Series (B/C/D/E): Muab cov qib sib txawv ntawm qis - qhov kub thiab txias cuam tshuam kev ua haujlwm, nrogQ345Eyog qhov haum tshaj plaws rau cov xwm txheej txias heev.
Daim ntawv thov
ASTM A333 Cov khoom lag luam: Siv hauvLNG cov nroj tsuag, tub yees tshuab, thiab cov kav dej cryogenic.
Cov Qib Hauv Tsev (09MnNiD, 16MnDG): Applied nyob rau hauvcov khoom siv petrochemical, qis- cov hlab ntsha siab, thiab khaws cia cryogenic
