Dab tsi yog cov khoom siv tawv rau cov roj carbon steel pob li qub

Carbon Steel Pob Valve Khoom Siv Khoom Siv Khoom Siv Khoom Siv thiab Kev Siv
I. HARD Alloy
Khoom Siv Khoom
Hard Alloy (xws li tungsten carbide) yog cov khoom siv ntawm carbon steel lossis sab saud, ntau dua lossis sib npaug zos rau cov scenes nruab nrab.
Ua los ntawm cov txheej txheem kub siab thiab cov txheej txheem siab siab, nws tuaj yeem tiv thaiv ib qho kub thiab txias ntau txog li 425 degree thiab ruaj khov nyob rau hauv roj av thiab tshuaj chemical.
Ii. Stainless hlau
Muaj cov xwm txheej muaj feem xyuam
Stainless hlau (xws li 304/316) feem ntau siv rau cov ntsaws ruaj ruaj me me thiab nruab nrab ntawm cov roj carbon me, thiab yog qhov haum rau dej, chav thiab qaug zog corrosive.
Hlau-rau-hlau sealing yog tiav los ntawm precision machining machining, nrog cov dej xau qis thiab kev txij nkawm ntev dua.
III. Alloy Steel
Kev kub siab thiab kub siab hloov tau
Alloy Steel (xws li WC6, WC9) txhim kho cov pa hluav taws xob siab los ntawm kev siv cov khoom siv chromium thiab molybdenum, thiab tuaj yeem tsim nyog rau cov chav dej siab hauv cov tshuab hluav taws xob kub.
Deg plating los yog kev kho cua sov tuaj yeem txuas ntxiv lub neej ntawm lub neej thiab txo cov oxidation poob siab.
4. Nickel-based alloys
Tsis tshua muaj neeg muaj ib puag ncig
Nickel-based alloys (xws li hastelloy) tau siv nyob rau hauv cov khoom siv acid
Txoj kev pheej hmoo ntawm lub suab tsis ua hauj lwm yuav poob qis hauv cov khoom siv tshuaj lom neeg lossis cov dej hiav txwv dej hiav txwv.
5. Xaiv cov lus pom zoo
Cov kev ua haujlwm ua haujlwm: cemented carbide lossis stainless hlau yog nyiam, coj mus rau hauv tus account ob qho kev ua tau zoo thiab raug nqi; Kev kub siab / particle-muaj tshaj tawm: alloy steel lossis cemented carbide yog ntau ruaj thiab xav tau los ua ke nrog lub cev kev kho cua sov; Muaj kev daws teeb meem: Nickel-booed alloy yog cov kev daws teeb meem zoo tshaj plaws, tab sis cov kev ua lag luam dav dav yuav tsum tau ntsuas.
