BS4504 CODE101 Phaj Flange rau Vuam DN50 PN16
Qhov kev txiav txim no yog los ntawm peb cov neeg siv khoom tshiab hauv teb chaws Africa thiab yog kev txiav txim siab, DN50, PN16 BS4504 CODE 101 Phaj flange rau vuam, Qhov ntau yog 1000 daim. Tom qab peb qhov kev soj ntsuam zoo thiab thib peb -kev kuaj xyuas tog, tam sim no peb tab tom ntim khoom thiab tos cov khoom xa tuaj.
Nyob rau tib lub sijhawm, peb cov neeg siv khoom African txaus siab heev rau qhov zoo ntawm peb cov khoom thiab npaj ua tiav cov kev txiav txim tom ntej tom ntej. Peb yuav txuas ntxiv xyuas kom zoo thiab muaj nuj nqis ntawm peb cov xaj.
BS4504 yog cov txheej txheem tshwj xeeb rau flange tsim thiab tsim khoom hauv British Standard, dav siv hauv cov kav dej txuas rau cov kav dej, li qub, twj tso kua mis, thiab lwm yam khoom siv, kom ntseeg tau tias kev sib khi thiab cov qauv tsim muaj zog.
Cov qauv no feem ntau qhia txog qhov loj me, qhov ntsuas siab, cov khoom siv, thiab txoj kev sib txuas ntawm flanges, thiab siv tau rau kev lag luam xws li roj av, tshuaj, dej kho, thiab hluav taws xob. Cov hom muaj xws li:
Vuam Neck Flange
Slip ntawm Phaj Flange
Qhov muag tsis pom flange
Qhov (socket) Weld Flange
Nws cov qib siab raug, xws li PN10, PN16, PN40, thiab lwm yam, sawv cev rau qhov siab tshaj plaws ua haujlwm siab ntawm qhov kub thiab txias. Piv txwv li, BS4504 PN10 yuav tsum muaj peev xwm tiv taus qhov siab ntawm 10 bar ntawm 120℃thiab muaj lub neej nkees nkees thiab lub zog nplaum, tshwj xeeb tshaj yog nyob rau txawv teb chaws engineering tej yaam num uas yuav tsum tau muaj kev ua tau zoo sib xws.
Qee cov tuam txhab lag luam tseem muab cov pob qij txha txuas ntxiv (tseem hu ua cov kev sib txuas muag muag lossis cov pob qij txha txuas ntxiv) uas ua raws li BS4504 cov qauv. Cov khoom no tsis yog tsuas yog yuav tsum tau flange loj sib piv, tab sis kuj tseem raug soj ntsuam nruj nruj (Ntau dua lossis sib npaug ntawm 6 kN / m) thiab 2000 lub voj voog ntawm kev qaug zog kom ua tau raws li qhov ntev - lub sijhawm ua haujlwm ruaj khov
Cov khoom siv rau BS4504 flanges nyob ntawm qhov kev ua haujlwm (xws li kub, siab, thiab corrosiveness ntawm qhov nruab nrab), feem ntau yog npog peb pawg: carbon steel, alloy steel, thiab stainless hlau, kom muaj zog txaus, corrosion kuj, thiab sealing kev ntseeg siab nyob rau hauv ntau yam kev lag luam ib puag ncig.
Cov khoom siv sib xws thiab cov qauv sib xws yog raws li hauv qab no:
Carbon Steel
Haum rau qhov kub thiab txias, nruab nrab thiab tsis tshua muaj siab ib puag ncig, nrog tus nqi qis thiab cov khoom siv zoo. Cov qib uas muaj xws li:
Q235, 20 #, A105 (muaj feem xyuam rau cov kav dej dav dav)
Q345, 16Mn (lub zog siab dua, haum rau cov xwm txheej uas xav tau siab dua)
Hlau alloy
Siv nyob rau hauv qhov kub thiab txias, kub siab los yog tshwj xeeb mechanical kev xav tau, xws li petrochemical, fais fab thiab lwm yam lag luam. Cov khoom siv xws li:
F11, F22, F91 (muaj chromium thiab molybdenum ntsiab, tiv taus kub creep)
A182 F5a, F9, F12 (raws li ASTM cov qauv, feem ntau siv nyob rau hauv siab -kub chav tshuab)
Stainless hlau
Muaj kev tiv thaiv corrosion zoo heev thiab tsim nyog rau cov kua qaub thiab alkaline xov xwm lossis ib puag ncig huv. Cov qauv muaj xws li:
F304 / F304L, F316 / F316L (universal stainless hlau, qhov twg L nruab nrab yog cov pa roj carbon tsawg thiab muaj zog tiv thaiv intergranular corrosion)
1Cr18Ni9Ti, 0Cr18Ni9Ti (cov qib hauv tsev, sib haum rau Asmeskas tus qauv 321, muaj cov titanium stabilization cov ntsiab lus, tsim nyog rau kev ua haujlwm yam tsis muaj annealing tom qab vuam)
