FRP Flange
Kev piav qhia txog khoom
FRP (Fiberglass Reinforced Plastic) flanges yog cov khoom sib txuas zoo li lub nplhaib siv los koom cov kav dej, cov qhov dej, cov twj tso kua mis, lossis lwm yam khoom siv los tsim kom muaj cov kav dej tiav. Lawv yog ua los ntawm cov khoom sib xyaw ua ke uas muaj cov iav fibers ua cov khoom siv txhawb nqa thiab cov khoom siv hluavtaws ua lub matrix. Lawv yog tsim los ntawm kev siv cov txheej txheem xws li molding, tes lay-up, lossis filament winding.
Cov yam ntxwv ntawm cov khoom
Ua tsaug rau lawv cov khoom sib xyaw tshwj xeeb, FRP flanges muaj cov txiaj ntsig zoo dua li cov hlau flanges ib txwm muaj:
- Kev Tiv Thaiv Kev Xeb Zoo Kawg Nkaus: Qhov tshwj xeeb tshaj plaws ntawm FRP flanges yog lawv lub peev xwm los tiv thaiv kev xeb los ntawm ntau yam tshuaj lom neeg, suav nrog cov kua qaub, alkalis, ntsev, thiab cov kuab tshuaj organic. Qhov no ua rau lawv siv dav hauv cov chaw uas cov kua dej corrosive raug thauj mus los, xws li hauv cov tshuaj lom neeg, roj av, metallurgy, fais fab, tshuaj, thiab zaub mov lag luam.
- Lub teeb yuag thiab muaj zog heev: Qhov ceev ntawm FRP feem ntau tsuas yog 1/4 txog 1/5 ntawm cov hlau, tab sis nws lub zog tuaj yeem sib piv tau. Qhov no ua rau lawv yooj yim dua rau kev thauj mus los thiab teeb tsa, thiab nws txo qhov hnyav tag nrho ntawm cov kav dej.
- Kev Rwb Thaiv Hluav Taws Xob Zoo: FRP yog cov khoom siv uas tsis ua rau muaj hluav taws xob, muab cov flanges FRP zoo heev rau kev rwb thaiv hluav taws xob. Qhov no tseem ceeb heev rau hauv cov chaw tshwj xeeb kom tiv thaiv kev xeb hluav taws xob.
- Kev Tsim Qauv Siab: Los ntawm kev kho cov qauv resin thiab kev npaj ntawm cov iav fibers, FRP flanges tuaj yeem ua raws li qhov xav tau tshwj xeeb rau qhov kub, siab, thiab kev tiv thaiv corrosion.
- Tus Nqi Txij Nkawm Tsawg: FRP flanges tsis xeb lossis nplai, ua rau lub neej ua haujlwm ntev thiab txo cov nqi txij nkawm thiab hloov pauv.
Hom Khoom
Raws li lawv cov txheej txheem tsim khoom thiab cov qauv, FRP flanges tuaj yeem faib ua ntau hom:
- Ib Daim (Kev Sib Koom Ua Ke): Hom no yog tsim los ua ib chav nrog lub cev yeeb nkab, muab cov qauv nruj uas haum rau cov ntawv thov qis mus rau nruab nrab.
- Flange Xoob (Lap Joint Flange): Muaj ib lub nplhaib flange xoob, tig tau ywj pheej thiab ib qho kawg ruaj khov ntawm cov yeeb nkab. Tus qauv no ua rau kev teeb tsa yooj yim, tshwj xeeb tshaj yog hauv kev sib txuas ntau lub ntsiab lus.
- Dig Muag Flange (Flange Dawb/Lub Npog Kawg): Siv los kaw qhov kawg ntawm cov yeeb nkab, feem ntau yog rau kev tshuaj xyuas cov kav dej lossis khaws cia qhov sib txuas.
- Lub Qhov (Socket Flange): Cov yeeb nkab raug ntxig rau hauv lub flange sab hauv thiab txuas ruaj khov los ntawm kev sib txuas nplaum lossis cov txheej txheem winding, kom ntseeg tau tias muaj kev ua haujlwm zoo sealing.
