Cov pa roj carbon steel flangesyog dav siv nyob rau hauv daim ntawv thov niaj hnub, nrog rau kev siv loj thiab ceev ceev. Yog li ntawd, kev saib xyuas tsis tu ncua ntawm cov pa roj carbon steel flanges yuav tsum muaj qee cov cai tswj xyuas cov pa roj carbon steel flanges kom zoo li sai tau thiab txhim kho kev ua haujlwm zoo. Cia kuv qhia rau koj txog kev saib xyuas tsim nyog rau kev ua haujlwm ruaj khov ntawmstainless hlauthiab carbon steel flanges.
1. Ua ntej siv, ntxuav cov yeeb nkab thiab cov dej ntws tawm ntawm lub valve lub cev nrog cov dej huv kom tsis txhob muaj cov hlau seem thiab lwm cov khib nyiab nkag mus rau hauv cov kab noj hniav hauv lub valve.
2. Thaum cov pa roj carbon steel flange raug kaw, qee qhov nruab nrab tseem nyob hauv lub cev valve thiab nws kuj muaj qee qhov siab. Ua ntej overhauling cov pa roj carbon steel flange, kaw lub kaw-off valve nyob rau hauv pem hauv ntej ntawm carbon steel flange, qhib cov pa roj carbon steel flange yuav tsum tau overhauled, thiab kiag li tso lub sab hauv siab ntawm lub valve lub cev. Nyob rau hauv cov ntaub ntawv ntawm hluav taws xob carbon steel flange los yog pneumatic pob valve, lub hwj chim thiab cua mov yuav tsum tau txiav ua ntej.
3. Feem ntau,PTFEyog siv los ua cov khoom sib khi rau mos sealing carbon steel flange, thiab sealing nto ntawm nyuaj sealing pob valve yog ua los ntawm hlau surfacing. Yog tias tsim nyog los ntxuav cov yeeb nkab pob valve, yuav tsum tau saib xyuas kom tsis txhob muaj cov pa tawm vim kev puas tsuaj rau lub nplhaib sealing thaum lub sij hawm disassembly.
4. Thaum disassembling cov carbon steel flange, cov bolts thiab ceev ntawm lub flange yuav tsum tau kho ua ntej, thiab ces tag nrho cov txiv ntseej yuav tsum tau nruj me ntsis thiab ruaj khov. Yog hais tias ib tus neeg raug yuam kom kho ua ntej lwm cov txiv ntoo raug kho, lub gasket nto yuav puas los yog tawg vim qhov tsis sib xws ntawm lub ntsej muag flange, uas ua rau muaj qhov nruab nrab los ntawm valve flange pob tw.
5. Yog tias lub valve raug ntxuav, cov kuab tshuaj siv yuav tsum tsis txhob cuam tshuam nrog cov khoom yuav tsum tau ntxuav thiab tsis corrode. Yog tias nws yog ib qho tshwj xeeb carbon steel flange rau roj, nws tuaj yeem ntxuav nrog roj av. Lwm qhov chaw tuaj yeem ntxuav nrog dej rov qab. Thaum lub sij hawm ntxuav, cov plua plav seem, roj thiab lwm yam txuas yuav tsum tau muab ntxuav kom huv. Yog tias lawv tsis tuaj yeem ntxuav nrog dej huv, lawv tuaj yeem ntxuav nrog cawv thiab lwm yam tshuaj ntxuav tes yam tsis muaj kev puas tsuaj rau lub cev thiab qhov chaw. Tom qab ntxuav, tos tus neeg saib xyuas kom volatilize ua ntej sib dhos.
6. Yog tias pom muaj cov pa me me ntawm cov ntim khoom thaum siv, lub valve qws txiv ntoo tuaj yeem raug nruj me ntsis kom txog thaum cov dej ntws tawm. Tsis txhob nroo ntxiv.
Tsis tas li ntawd, yog tias cov pa roj carbon steel flange muab tso rau sab nraum zoov lub sijhawm ntev, yog tias tsis muaj kev ntsuas dej tsis zoo thiab tsis muaj dej noo, nws yuav ua rau corrosion ntawm qee lub valve lub cev thiab cov khoom siv. Txhawm rau kom muaj kev ruaj ntseg ntawm cov pa roj carbon steel flange, qhov kev sim yuav tsum tau ua ua ntej siv.
