Loj txoj kab uas hla flange raws li ib tug ntau flange, vim hais tias nws yuav siv tau rau ntau yam sib txawv lub sij hawm thiab qhov zoo ntawm cov nyhuv zoo los ntawm kev lag luam hlub, cov khoom yog dav siv nyob rau hauv machinery thiab tshuaj kev lag luam thiab lwm yam industries, cia DHDZ flange manufacturers qhia lub hauv paus ntsiab lus ntawm kev sib dhos thiab kev tsim kho los tiv thaiv corrosion.

I. Kev sib dhos txoj cai thiab cov cai ntawm txoj kab uas hla loj flanges
1. Thaum sib sau ua ke ib khub ntawm flanges, lub qhov ntsia liaj qhov rooj ntawm lub mounting flanges yuav tsum tau ua raws li cov ntsia liaj qhov rooj qhov sib thooj rau cov flanges ruaj khov thiab sib npaug rau cov flanges ruaj khov.Qhov sib txawv yuav tsum tsis txhob ntau tshaj 1.5 thiab 2 hli ntawm lub cheeb ntawm lub flanges.
2. Tshawb xyuas thiab kho qhov flange txoj hauj lwm los ntawm sab laug thiab txoj kev taw qhia nrog 90 square feet, thiab ua tiav qhov chaw vuam thiab kho qhov loj txoj kab uas hla flange los ntawm qhov thib peb thiab plaub taw tes tom qab qhov chaw vuam.
3. Thaum xaiv qhov sib txuam flanges ntawm cov khoom siv los yog lub valve sib dhos, yuav tsum tau saib xyuas seb cov flanges ntawm cov khoom qub lossis lub valve sib dhos yog tib yam li cov khoom siv hauv cov kav dej.
4. Thaum sib dhos tiaj-welded flanges, cov yeeb nkab kawg yuav tsum tau muab tso rau 2/3 ntawm lub thickness ntawm lub puab txoj kab uas hla ntawm lub flange, thiab ces pom weld lub flange rau cov yeeb nkab.Rau cov yeeb nkab kab rov tav, qhov chaw weld los ntawm saum toj no, tom qab ntawd xyuas qhov kev ntsuas flange los ntawm cov lus qhia sib txawv nrog 90 square feet kom qhov chaw sib khi yog perpendicular mus rau nruab nrab ntawm cov yeeb nkab, tom qab ntawd qhov chaw weld hauv qab qhov chaw.
5. Ua ntej sib dhos lub flange, ntxuav lub flange nto, tshwj xeeb tshaj yog cov sealing nto.

Ob, cov txheej txheem kev ua haujlwm thiab cov yam ntxwv ntawm txoj kab uas hla loj flange los tiv thaiv corrosion
Sealing corrosion inhibitor rau flange clearance filling ntawm txoj kab uas hla loj.Muab daim ntawv (pob tshab) daim kab xev rau ntawm ntug flange kom tiv thaiv lub flange los ntawm kev qias neeg thaum txhaj tshuaj tiv thaiv corrosion;foob ​​thiab sau flange clearance nrog corrosion inhibitor los xyuas kom meej flange clearance yog sau nrog sealing corrosion inhibitor.
Tom qab sau qhov sib txawv ntawm flange nrog corrosion inhibitor, siv lub putty scraper los polish lub nto du raws lub voj voog ncig, kom qhov sib txawv thiab flange ntug hauv tib lub dav hlau.Tshem tawm ob sab ntawm daim kab xev.
Yog tias koj siv flange anticorrosion cream, koj yuav tsum siv rab riam los txiav cov flange anticorrosion cream rau hauv nqaim strips, thiab tom qab ntawd raws li qhov dav ntawm flange qhov sib txawv, ncaj qha sau cov flange kis ntawm tes.Nias thaum sau.
Clearance thiab kho nto ntawm txoj kab uas hla loj flange.Tshem tawm cov xeb ntawm lub flange clearance thiab screws nrog ib tug txhuam;Ntxuav flange clearance nrog compressed cua;Yog tias siv tshuaj tshem tawm, tshuaj xyuas seb cov tshuaj tshem tawm puas yuav cuam tshuam rau flange foob.
Yog tias tsis ntseeg, nws raug nquahu kom tsis txhob siv cov txheej txheem tshuaj;So flange nto nrog ntawv xuab zeb lossis paj rwb xov kom ua tau raws li tus qauv ST2.
