Corrugated Graphite Sealing Daim kab xev

1. Core Product Positioning

Corrugated Graphite Sealing Daim kab xev yog tsim los ntawm 99.5% siab -purity flake graphite raws li lub substrate, compounded nrog ib tug kub thiab txias -resistant elastic nplaum (qhov kub siab tshaj ntawm 800 degree), thiab tsim los ntawm cov ntaub ntawv loj - optimized "precision corrugated forming}} + txheej txheem kub {6 nws lub luag haujlwm tseem ceeb yog muab "kev sib khi ruaj khov + kev teeb tsa yooj yim + kev pabcuam ntev" kev daws teeb meem rau cov xwm txheej kev lag luam (cov kav dej, lub li qub, cov reactors) xws li nruab nrab- qis rau nruab nrab- kub (-200℃~ 800℃). Nws hais txog qhov mob ntawm cov kab mob carcinogenic ntawm cov tsoos asbestos gaskets, qhov kub tsis txaus ntawm cov roj hmab gaskets (yuav ua rau kev laus ntawm qhov kub thiab txias 250 degree), thiab kev hloov tsis zoo ntawm cov graphite gaskets. Qeb ntawm TOP 4 cov khoom lag luam loj tshaj plaws nyob rau xyoo 2025 thoob ntiaj teb kev sib khi cov khoom lag luam (19.3% txhua xyoo kev loj hlob tus nqi, nrog petrochemical / dej kho / kev siv tshuab dav dav suav txog 76%; Cov ntaub ntawv Source: Ntiaj Teb Kev Lag Luam Sealing Materials Market Report 2025).

Tsis muaj brittleness los yog tawg ntawm qhov kub thiab txias (10 folds ntawm -200℃tsis tawg) thiab tsis muaj carbonization ntawm nruab nrab - kub, ua rau nws haum rau scenarios xws li pipelines nyob rau hauv frigid sab qaum teb cheeb tsam (-40 degree), zaub mov sterilization khoom (150 degree), thiab chemical reactors (60 ° C). Kev ua haujlwm ntau-txheej xwm sealing tsis ua haujlwm ntawm cov neeg siv khoom qis qis yog txo los ntawm 85%.

Siab -Kev Ua Tau Zoo Sealing & Kev Tiv Thaiv Kev Tawm: Qhov tshwj xeeb "arc-zoo li tus corrugated qauv" (corrugation qhov siab: 0.3-2.5mm, customizable) nce qhov chaw sib cuag ntawm lub sealing nto los ntawm 45%. Tom qab 1,000 qhov nruab nrab-siab siab sealing kev ntsuam xyuas (qhov siab tshaj plaws ntawm 18MPa), tus nqi xau tsawg dua los yog sib npaug rau 8 × 10⁻⁷ Pa·m³ / s, deb tshaj li Tuam Tshoj Tus Txheej Txheem GB / T 4622.3-2021 rau kev sib khi dav dav (tsawg dua lossis sib npaug li 1 ⁵ ³ Pa). Qhov tsim nyog tus nqi ntawm flange sealing rau petrochemical pipelines ncav cuag 99.4%.

Strong Corrosion Resistance & Chemical Compatibility: Tom qab 960 xuab moos ntawm kev sim raus dej (acid-cov ntsiab lus daws nrog pH 2-13, cov kuab tshuaj organic xws li acetone/ethylene glycol), qhov poob qis yog tsawg dua lossis sib npaug li 1.8%, tsis muaj qhov o lossis delamination. Tsim nyog rau kev sib khi cov tshuaj chlorine- muaj cov kav dej khib nyiab hauv kev lag luam kho dej (chlorine corrosion kuj) thiab tsis muaj zog acid-puag xov xwm hauv kev lag luam tshuaj, nws lub neej kev pab cuam txuas ntxiv mus rau 2-3 xyoos, piv rau cov roj hmab gaskets (uas muaj kev tiv thaiv corrosion ntawm 3 lub hlis).

High Adaptability & Yooj Yim Txheej Txheem: Thickness ranges ntawm 0.2-6mm (customizable), nrog rau chav-kub yooj yooj yim enables 300 dabtsi yog khoov voj voog yam tsis muaj kab nrib pleb. Nws tseem tuav ib qho elasticity ntawm 800℃(compression rebound tus nqi ntau dua los yog sib npaug rau 85%). Los ntawm CNC txiav kev sim, ntug flatness tom qab txiav rau hauv qhov ntau thiab tsawg (qhov siab tshaj plaws ntawm 1,500mm) thiab qhov chaw sib khi tsis tu ncua (xws li, elliptical flanges) tsawg dua lossis sib npaug li 0.1 hli. Nws yog sib xws nrog ntau tshaj 96% ntawm kev lag luam sealing nto (flanges, li qub, twj), thiab kev txhim kho kev ua haujlwm yog 55% siab dua li cov tsoos sealing gaskets.

 

 

4. Cov ntawv thov tseem ceeb

Petrochemical Field(35% kev faib ua feem, qhov loj tshaj plaws daim ntawv thov scenario): Corrugated Graphite Sealing daim kab xev yog siv rau sealing crude roj xa mus pipeline flanges (-20℃~ 80 degree) thiab nruab nrab-kub pipelines ntawm catalytic cracking units (300℃~ 500 degree). Raws li kev sim cov ntaub ntawv los ntawm PetroChina Lanzhou Petrochemical, nws tuaj yeem txo cov kav dej xau tsis ua haujlwm ntawm 6.1% mus rau 0.4%, thiab txiav cov nqi kho txhua xyoo ntawm ib chav tsev los ntawm 380,000 RMB. Tsim nyog rau cov kav dej uas muaj leej faj nruab nrab (hydrogen sulfide corrosion resistance), nws sealing kev ntseeg tau ua tau raws li qhov yuav tsum tau ua ntawm kev tsim khoom tas mus li.

Kev Kho Dej Field(22% kev faib ua feem): Siv los ua kev sib khi rau cov twj centrifugal hauv cov chaw kho dej phwj (chaw kub, chlorine- muaj cov dej khib nyiab) thiab cov kav dej flanges hauv cov dej ua haujlwm (-5℃~ 40℃). Nws lub neej kev pab cuam txuas mus rau 2.5 xyoo, piv rau cov roj hmab gaskets (yuav ua rau corrosion thiab kev laus los ntawm cov tshuaj chlorine), thiab qhov nruab nrab sealing hloov lub voj voog ntawm cov khoom siv dej yog txuas ntxiv los ntawm 2 lub hlis mus rau 18 lub hlis.
