1. Xaiv txoj kev sib txuas tsim nyog raws li txoj kab uas hla thiab cov xwm txheej tshwj xeeb ntawm cov yeeb nkab.
①Welding: Kev teeb tsa yuav pib thaum lub sijhawm tsim nyog raws li kev ua tiav ntawm qhov chaw. Txhim kho cov brackets ua ntej, kos ib daim duab kos raws li qhov loj me, thiab prefabricate cov kav dej kom txo qis fittings thiab vuam cov pob qij txha tuag ntawm cov kav dej. Cov kav dej yuav tsum ncaj nraim ua ntej, thiab qhov qhib yuav tsum raug kaw thaum lub installation cuam tshuam. Yog hais tias tus tsim yuav tsum tau casing, lub casing yuav tsum tau ntxiv thaum lub installation txheej txheem. Raws li qhov yuav tsum tau ua ntawm tus tsim thiab cov cuab yeej siv, cia lub interface, kaw nws, thiab npaj rau cov kauj ruam tom ntej ntawm kev sim. Kev ntxhov siab ua haujlwm.
②Threaded kev twb kev txuas: Cov yeeb nkab threads yog ua tiav siv lub tshuab threading. Kev ceev threading tuaj yeem siv rau 1/2 "-3/4" kav. Tom qab threading, cov yeeb nkab qhib yuav tsum tau ntxuav thiab ua kom du. Cov xov tawg thiab cov xov uas ploj lawm yuav tsum tsis pub tshaj 10% ntawm tag nrho cov xov. Qhov kev sib txuas yuav tsum ruaj khov, tsis muaj qhov cuam tshuam lint ntawm lub hauv paus. Cov xov raug nthuav tawm ntawm cov hauv paus hniav yuav tsum tsis txhob ntau tshaj 2-3 buckles, thiab qhov cuam tshuam ntawm cov xov yuav tsum zoo tiv thaiv corrosion.
③Flange kev twb kev txuas: Flange kev twb kev txuas yuav tsum tau nyob rau hauv kev sib txuas ntawm cov kav dej thiab li qub. Flanges tuaj yeem muab faib ua welding flanges, taub qab vuam flanges, thiab lwm yam. Cov flanges yog ua los ntawm cov khoom tiav. Cov kab nruab nrab ntawm flange thiab cov yeeb nkab yog perpendicular, thiab cov yeeb nkab qhib yuav tsum tsis txhob protrude los ntawm flange sealing nto. Cov bolts uas fasten lub flange yuav tsum tau txhuam nrog lubricating roj ua ntej siv. Lawv yuav tsum tau symmetrically hla thiab nruj hauv 2-3 zaug. Qhov ntev ntawm cov ntsia hlau yuav tsum tsis pub tshaj 1/2 ntawm cov ntsia hlau taub. Cov txiv ntseej yuav tsum nyob rau tib sab. Lub flange gasket yuav tsum tsis txhob protrude rau hauv cov yeeb nkab. , yuav tsum tsis muaj inclined ncoo los yog ntau tshaj ob lub ncoo nyob rau hauv nruab nrab ntawm lub flange.

2. Anti-corrosion: Cov kav dej uas raug galvanized yuav tsum tau pleev xim nrog ob lub tsho tiv no ntawm cov hmoov nyiaj, thiab cov kav dej zais galvanized yuav tsum tau pleev xim nrog ob lub tsho ntawm asphalt.

3. Ua ntej tso thiab txhim kho cov kav dej, cov av hauv tsev yuav tsum tau ntxuav kom tsis txhob vuam slag thiab lwm yam khib nyiab los ntawm cov kav dej. Cov kav dej tau nruab yuav tsum tau muab qhwv thiab kaw.

4. Tom qab kev tsim kho tiav lawm, tag nrho cov txheej txheem yuav tsum tau kuaj xyuas hydrostatic siab. Lub siab ntawm cov dej hauv tsev yog 0.6mpa. Yog tias qhov poob siab tsis tshaj 20kpa hauv tsib feeb, nws tsim nyog.
