ASTM A694 yog qib American steel
ASTM A694 Forgings rau Carbon thiab Alloy Steel Yeeb Nkab Flanges, Fittings, Valves thiab Parts rau Cov Khoom Siv Hluav Taws Xob
A694 muaj tag nrho ntawm F42 F46 F48 F50 F52 F56 F60 F65F70
A694 yog qib steel hauv Tebchaws Meskas, thiab nws cov tshuaj muaj pes tsawg leeg yog ze rau Q345D hauv Suav teb. Q345D yuav tsum tau ua raws li cov txheej txheem kev kho cua sov nruj ua ntej ncav cuag cov khoom siv kho tshuab ntawm A694 F60.
Tsis tas li ntawd, ASTM A694 Gr.F60 kuj yog cov khoom siv hlau tsis tshua muaj hlau siv rau cov yeeb nkab fittings nyob rau hauv siab thiab kub siab, yog li nws tseem hu ua A694 F60 high pressure fittings.
Cov khoom siv no feem ntau yog siv rau kev sib txuas ntawm cov kav dej siab hauv cov roj, cov nkev thiab tshuaj lom neeg kev lag luam, thiab muaj zog tensile siab thiab corrosion kuj.
Raws li rau lub hardness ntau ntawmASTM A694 Gr. F60tsis muaj qhov tshwj xeeb hardness yuav tsum tau. Lub hardness nyob ntawm cov kev kho cua sov tshwj xeeb thiab cov khoom siv. Feem ntau, qhov nyuaj ntawm A694 F60 cov khoom raug kuaj raws li Brinell hardness (HB) lossis Rockwell hardness (HRC). Tus nqi hardness yuav txawv raws li cov tshuaj muaj pes tsawg leeg, kev kho cua sov thiab kev tsim cov khoom siv.
Siv lub pob tw weld flange ntawm A694 F60 ua piv txwv los piav qhia:
A694 F60taub qab vuam flangetsis yooj yim rau deform, muaj zoo sealing thiab yog dav siv. Nws muaj feem xyuam rau cov kav dej uas muaj kev kub ntxhov loj lossis kub hloov pauv lossis kub siab, siab siab thiab qis kub pipelines. Nws feem ntau yog siv rau kev sib txuas ntawm cov kav dej thiab cov li qub nrog PN siab dua 2.5MPa; Nws kuj yog siv rau hauv cov kav xa dej xa khoom kim, flammable thiab explosive media. Nws muaj lub neej ua haujlwm ntev. Raws li cov ntaub ntawv kuaj corrosion, nws lub neej kev pabcuam tuaj yeem ncav cuag 100 xyoo thiab tsis tshua xav tau kev saib xyuas. Yog li ntawd, nws qhov kev ua tau zoo-tus nqi piv yog qhov zoo heev, nws cov nqi khiav lag luam hauv lub neej qis, thiab nws cov txiaj ntsig kev lag luam tseem ceeb.
A694 F60 pob tw vuam flange yog tus cwj pwm los ntawm kev txhim khu kev qha thiab kev nyab xeeb, kev tsim kho yooj yim thiab nrawm, kev ua haujlwm zoo thiab kev tiv thaiv ib puag ncig, kev poob siab me me, muaj zog ua haujlwm sib raug zoo, ob qho tib si qhib thiab zais kev teeb tsa, tsis muaj kev txuas ntxiv thiab kev saib xyuas, kev lag luam zoo dua, thiab dav siv ntau yam. Nws muaj feem xyuam rau pej xeem cov dej tsis tshua muaj siab kis tau tus mob xws li dej txias thiab kub, dej haus ncaj qha, cua sov, cua txias, tiv thaiv hluav taws, roj, thiab lwm yam, nrog rau cov tshuaj, dej haus, khoom noj khoom haus uas tsis tshua muaj siab kis tau tus mob nyob rau hauv tshuaj lom neeg kev lag luam thiab lwm yam kev lag luam.
