Yuav Ua Li Cas Xaiv Txoj Cai Mounting Flange Khoom thiab Gasket rau PTFE Rhaub
Tso lus
Lub PTFE rhaub yog mounted rau lub tank ntawm lub mounting flange. Cov khoom siv flange yuav tsum haum nrog lub tank phab ntsa kom tiv thaiv galvanic corrosion thiab gasket yuav tsum muab khi rau cov txheej txheem dej tsis muaj degradation. "Kev xaiv cov flange thiab cov ntaub ntawv gasket yog qhov tseem ceeb rau kev ncaj ncees thiab kev ua haujlwm ntev -.
Hom Flange Cov Khoom Siv rau PTFE Heaters Daim Ntawv Thov
Cov khoom siv ntawm lub flange mounting yog ib qho tseem ceeb los muab kev cia siab rau kev xau -kev sib txuas dawb ntawm PTFE lub rhaub rau lub tank. Cov ntaub ntawv flange yuav tsum haum nrog cov khoom siv hauv lub tank kom tsis txhob galvanic corrosion thiab tsim kom muaj lub foob kaw ntom ntom. Cov khoom siv dav dav rau flanges yog:
316L Stainless hlau
Feem ntau thiab cov khoom siv thoob ntiaj teb rau mounting flanges yog 316L stainless hlau. Nws muaj qhov zoo corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv chloride - nplua nuj tej yam kev mob, thiab yog li no haum rau ntau yam kev siv. Cov khoom no muaj zog heev thiab ua haujlwm zoo nyob rau hauv qhov kub thiab txias. Qhov no ua rau nws yog ib qho kev xaiv zoo rau feem ntau cov tshuab tank.
Yas Tank Flanges
Rau cov tso tsheb hlau luam ntawm polypropylene (PP), polyvinyl chloride (PVC) lossis polyvinylidene fluoride (PVDF) nws yog ib qho tsim nyog los xaiv cov flange uas ua los ntawm cov yas kom tsis txhob galvanic corrosion. Nyob rau hauv cov xwm txheej no, PTFE-lined steel flange tuaj yeem siv tau, uas muab cov txiaj ntsig zoo ntawm cov khoom siv hlau nrog cov tshuaj tsis haum ntawm PTFE, muab cov ntawv cog lus ruaj khov yam tsis muaj kev sib tw galvanic. Cov flanges no tshwj xeeb tshaj yog muaj txiaj ntsig zoo rau cov chaw ua tshuaj lom neeg uas tso tsheb hlau luam ntawm cov ntaub ntawv yas yog nyob txhua qhov chaw.
Titanium Flange
Titanium flanges yog lwm txoj hauv kev rau cov tshuaj chloride hnyav tshaj plaws xws li dej hiav txwv lossis kev ua haujlwm tshuaj lom neeg heev. Titanium yog ib qho khoom siv zoo rau kev thov kev lag luam vim nws lub zog siab - mus rau - qhov hnyav piv thiab superior corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv muaj chlorides.
Nyob rau hauv kev xyaum, cov khoom ntawm lub mounting flange rau PTFE rhaub daim ntaub ntawv yuav tsum tau xaiv raws li kev tsim kho ntawm lub tank. Corrosion: Siv cov khoom sib txawv tuaj yeem ua rau corrosion uas ua rau lub flange tsis muaj zog thiab tuaj yeem tawg lub foob.
Xaiv cov khoom siv Gasket
Lub gasket tsim cov ntaub ntawv tseem ceeb ntawm PTFE lub rhaub thiab lub tank, tsis txhob xau thiab khaws cia kev ncaj ncees. Cov khoom uas tau xaiv yuav tsum tau sib haum nrog rau da dej chemistry thiab muaj peev xwm tiv taus qhov kub thiab txias. Qee yam ntawm cov khoom siv gasket feem ntau yog:
PTFE Gaskets (khoom los yog hnab ntawv)
PTFE gaskets tiv taus ntau yam tshuaj, yog li lawv tsim nyog rau feem ntau daim ntawv thov xav tau PTFE cua sov. Raws li qhov yuav tsum tau ua, ob qho tib si PTFE gaskets thiab lub hnab ntawv gaskets (nrog rau lub hnab ntawv PTFE nyob ib puag ncig lwm cov khoom) yog siv. PTFE gaskets muaj universal chemical resistance thiab haum rau corrosive los yog siab - daim ntawv thov kub.
Ib qho qauv zoo yog cov khoom PTFE rau cov kua corrosive heev thiab lub hnab ntawv gaskets thaum xav tau kev txhawb nqa tshuab ntxiv, tshwj xeeb tshaj yog nyob rau hauv kev siv hluav taws xob lossis kev siv siab.
Viton Gasket
Viton yog resistant rau acids thiab kub kub; tsim nyog siv rau hauv cov ntawv thov uas muaj cov kua qaub acidic. Viton yog elastic thiab seals zoo tab sis tsis zoo rau cov tshuaj caustic muaj zog vim nws tuaj yeem ua rau qhov chaw nyob ntawd. Viton yog dav siv rau kev siv tshuaj lom neeg hauv cov kua qaub tab sis yuav tsum tau zam hauv cov hauv paus muaj zog.
EPDM Roj Hmab Gasket
EPDM (Ethylene Propylene Diene Monomer) gaskets yog siv dav hauv cov dej kub, chav dej thiab dej cawv. EPDM tiv taus qhov kub thiab txias heev. Txawm li cas los xij, EPDM gaskets swell nyob rau hauv muaj cov roj thiab cov kuab tshuaj thiab yog li tsis qhia rau siv nrog lawv.
Lub gasket yog ib qho pheej yig tsis tau yog lub foob tseem ceeb uas tseem ceeb rau kev xau- ua haujlwm dawb. Kev zam kom tsis txhob muaj kev puas tsuaj ntxov ntxov thiab tsis ua haujlwm yog qhov tseem ceeb thiab nyob ntawm kev xaiv cov khoom tsim nyog xav txog kev ua dej da dej thiab kev ua haujlwm kub.
Technical Aspects ntawm Flange thiab Gasket Xaiv
Cov txheej txheem txheej txheem yuav tsum tau hais thaum txiav txim siab lub mounting flange thiab gasket cov ntaub ntawv:
Flange Standards: Flange tsim thiab ntsia liaj qhov rooj qauv yog tsim los ntawm ANSI, DIN thiab JIS. Nws yog ib qho tseem ceeb uas cov flange bolt qauv phim lub tank nozzle kom lav zoo installation thiab sealing.
Gasket Compression Set: Lub gasket yuav tsum muaj peev xwm tswj tau lub foob ruaj khov thaum lub sij hawm tsis muaj compression teeb. Compression set thiab tshuaj tiv thaiv cov ntaub ntawv feem ntau yog muaj los ntawm cov neeg tsim khoom gasket thiab yuav tsum tau txiav txim siab hauv cov khoom xaiv.

Cov ntsiab lus
Lub gasket thiab mounting flange yog ib qho tseem ceeb ntawm cov pa tawm -dawb, corrosion resistant installation ntawm PTFE rhaub. Kev saib xyuas kom zoo rau cov khoom flange compatibility nrog lub tank tsim thiab ceev faj xaiv cov khoom siv gasket raws li da dej chemistry thiab qhov kub thiab txias yuav ua rau muaj kev txhim khu kev qha thaum lub neej ntawm lub rhaub. Cov ntaub ntawv gasket thiab flange yuav tsum tau tsim los tiv thaiv cov tshuaj lom neeg ib puag ncig nrog rau cov khoom siv kho tshuab kom tsim tau lub sijhawm ntev, txij nkawm dawb foob. Ntxiv mus, lub rhaub yog ib feem ntawm lub system loj thiab tag nrho cov interfaces yuav tsum tau tsim rau compatibility nyob rau hauv thiaj li yuav ua kom lub system ruaj khov thiab kev ua tau zoo.
