ASTM A350 LF2 pob valve yog ib qhoAsmeskas tus qauv qis-kub forged steel pob valvenrog lub forged steel lub cev uas tswj cov dej ntws los ntawm kev tig pob. Nws tuav cov khoom siv zoo heev thiab kev sib khi ua haujlwm nyob rau hauv qhov tsis tshua muaj siab - qhov kub thiab txias, ua kom ntseeg tau kev ua haujlwm hauv cov tshuab cryogenic.
Cov yam ntxwv tseem ceeb:
Tsawg-Qhov Kub Adaptability
Ua los ntawm kev kho tshwj xeeb forged steel, nws tuav txhua yam thiab sealing kev ua tau zoo nyob rau hauv ultra- kub qis (-196℃rau -150 degreelos yog lwm yam kev teev tseg).
Siab zog & Hardness
Lub cev lub cev thiab cov khoom siv sab hauv yog forged los ntawm cov khoom xws liStainless hlau (304, 316), kom muaj zog txaus, hardness, thiab corrosion kuj.
Sealing Performance zoo heev
Feem ntau sivPEEK lossis lwm yam tsawg-kub- cov ntaub ntawv sealing uas tsis muaj zog, muab superior siab thiab cryogenic kuj rau txhim khu kev qha sealing.
Extended Stem Design
Features ibncua qiatxhawm rau tiv thaiv kom khov ntawm cov qia ntim hauv qhov kub thiab txias, ua kom muaj kev ua haujlwm zoo.
Lub valve no zoo tagnrho rauDaim ntawv thov cryogenichauv kev lag luam xws liroj & roj, LNG, thiab tshuaj ua haujlwm, qhov twg kev nyab xeeb thiab kav ntev yog qhov tseem ceeb.

ASTM A350 qib LF2 khoom yog dab tsi?
ASTM A350 LF2yog alow-kub forged steel khoomhauv qabAsmeskas cov qauv, poob rau hauv qeb ntawmcarbon thiab qis- alloy steel forgings. Nws yog feem ntau siv rau kev sib txuas hauvqis-cov kav dej kub, cov hlab ntsha siab, thiab cov khoom siv.
Khoom yam ntxwv
Tsawg-Kev Ua Haujlwm Kub: Haum rau ib puag ncig xws li-46℃rau -101 degree,s nrogLF 2feem ntau yog siv rau-46 degreethiabLF3rau qhov kub tsis txias ntau dua (-101 degree).
Daim ntawv thov: Siv hauvlow-kub piping systemsthoob plaws kev lag luam xws liroj & roj, petrochemical, nkoj tsim, thiab aerospace.
Dab tsi yog qhov txawv ntawm ASTM A350 LF2 thiab A105?
A105 yog US tus qauv carbon steel forging, adhering rauASTM A105 / A105M-2010 (Carbon Steel Forgings rau Piping Cheebtsam). Raws li tus qauv no tsuas yog ib hom carbon steel forging, A105 yog ib qib zoo ntawm forged carbon hlau.
LF2 yog US tus qauv qis-kub steel forging, ua raws liASTM A350 / A350M-2018 Cov Lus Qhia Tshwj Xeeb. Nws belongs rau qeb ntawmcarbon thiab qis- alloy steel forgings rau piping Cheebtsam uas yuav tsum tau notch toughness kuaj.
Cov Lus Cim Tseem Ceeb:
A105 yog ib qho dav dav -lub hom phiaj carbon steel forging rau tus qauv- qhov kub thiab txias.
LF 2yog qhov qis -kub variant (nrogLF3rau txawm tias qhov kub thiab txias) tsim los tswj cov tawv nqaij hauv qhov chaw cryogenic.
Ob leeg tau siv dav hauv cov kav dej, tab sis LF2 tshwj xeeb yog xaiv rau qis - qhov kev pabcuam kub (xws li LNG, tub yees).
