Flange e kholo ea bophara e le flange e tloaelehileng, hobane e ka sebelisoa liketsahalong tse fapaneng tse fapaneng le melemo ea phello e ntle ke indasteri e ratoang, sehlahisoa se sebelisoa haholo indastering ea mechine le lik'hemik'hale le liindasteri tse ling, lumella baetsi ba DHDZ flange ho hlahisa litlhoko tsa molao-motheo oa kopano le kaho ea anti-corrosion.

I. Molao-motheo oa kopano le litlhoko tsa li-flange tse kholo tsa bophara
1. Ha u bokella li-flanges tse peli, likoti tsa bolt tsa li-flange tse ntseng li phahama li lokela ho lumellana le likoti tsa bolt tse lumellanang le li-flange tse tsitsitseng le tse tšoanang le li-flange tse tsitsitseng.Phapang ha ea lokela ho ba kholo ho feta 1.5 le 2mm ea bophara bo ka ntle ba flanges.
2. Sheba le ho lokisa boemo ba flange ho tloha ka lehlakoreng le letšehali le ka ho le letona ka maoto a lisekoere tse 90, 'me u qete ho tjheseletsa sebaka le ho lokisa bophara bo boholo ba flange ka ntlha ea boraro le ea bone ka mor'a ho cheseletsa matheba.
3. Ha ho khethoa li-flange tse ts'oanang tsa lisebelisoa kapa kopano ea li-valve, tlhokomelo e lokela ho nkoa ho bona hore na li-flange tsa thepa ea pele kapa kopano ea li-valve li tšoana le tse sebelisoang phapeng.
4. Ha ho bokelloa li-flange tse nang le li-flange tse nang le li-flange, qetellong ea phala e lokela ho kenngoa ka 2/3 ea bophara ba bophara bo ka hare ba flange, ebe o bona letheba la weld ho phala.Bakeng sa peipi e tšekaletseng, beha weld ho tloha holimo, ebe u sheba boemo ba flange ho tloha mahlakoreng a fapaneng ka maoto a lisekoere a 90 e le hore bokaholimo bo tiisehe ho ea bohareng ba phala, ebe u bona weld ka tlase ho letheba.
5. Pele o kopanya flange, hloekisa holim'a flange, haholo-holo sebaka sa ho tiisa.

Ea bobeli, ts'ebetso ea ts'ebetso le litšoaneleho tsa kaho ea anti-corrosion ea bophara bo boholo
Ho tiisa corrosion inhibitor bakeng sa ho tlatsa flange clearance ea bophara bo boholo.Beha pampiri (e pepeneneng) theipi ka lehlakoreng la flange ho thibela hore flange e se ke ea silafala ha e kenya corrosion inhibitor;Koahela 'me u tlatse tumello ea flange ka corrosion inhibitor ho netefatsa hore flange clearance e tlatsitsoe ka sealing corrosion inhibitor.
Ka mor'a ho tlatsa lekhalo la flange ka corrosion inhibitor, sebelisa putty scraper ho bentša bokaholimo bo boreleli ho latela tataiso ea circumferential, e le hore lekhalo le moeli oa flange sefofaneng se le seng.Khaola mahlakore ka bobeli a tepi.
Haeba u sebelisa flange anticorrosion tranelate, u lokela ho sebelisa thipa ho khaola flange anticorrosion tranelate ka e hlobolisa moqotetsane, 'me joale ho ea ka bophara ba flange lekhalo, ka ho toba tlatsa flange lekhalo ka letsoho.Tobetsa fatše ha o tlatsa.
Ho hlaka le ho phekola ka holim'a flange e kholo ea bophara.Tlosa mafome holim'a tumello ea flange le li-screws ka borashe;Hloekisa flange ka moea o hatelitsoeng;Haeba ho sebelisoa lik'hemik'hale, hlahloba hore na ho tlosa lik'hemik'hale ho tla ama flange seal.
Haeba u belaella, ho kgothaletswa hore o se ke wa sebelisa mekhoa ea lik'hemik'hale;Hlakola bokaholimo ka sandpaper kapa khoele ea k'hothone ho fihlela maemo a ST2.
