1. Cua txias cov yeeb nkab tooj liab tuaj yeem ntsia tau qhib, kev teeb tsa tsaus, pom zoo rau kev teeb tsa tsaus. Cov laj thawj tseem ceeb: 1) cov kav dej tooj liab tau nruab rau hauv qhov qhib, hauv qee qhov chaw ib puag ncig yuav tsim tooj liab ntsuab rau sab nrauv ntawm cov yeeb nkab tooj liab, cuam tshuam rau kev zoo nkauj; 2) Cov khoom siv ntawm cov yeeb nkab tooj liab yog mos, xws li qhib nteg, cov kav dej tooj liab yuav raug rub, nce toj, dai, nplawm, kov thiab lwm yam, ua rau deformation ntawm cov yeeb nkab tooj liab, uas ua rau cov dej xau.
2. Lub cev thiab riser yuav tsum tau muab zais rau hauv qab nthab, lub qhov dej, cov yeeb nkab qhov; ceg yeeb nkab yuav tsum tau muab tso rau hauv av leveling txheej, zoo nkauj phab ntsa los yog yeeb nkab zawj txiav raws phab ntsa. Cov kav dej tso rau hauv cov yeeb nkab zawj, cov yeeb nkab txoj kab uas hla yuav tsum tsis txhob siab dua DN25 (Ceeb toom: lub teb chaws architectural standard design drawings teem rau DN20), thiab yuav tsum tau siv rau yas-coated tooj liab yeeb nkab, zawj tooj liab yeeb nkab yuav tsum tau tsau ntsuas.
3. Riser yuav tsum tau npaj rau hauv cov dej siv cov khoom siv huv huv lossis cov khoom siv nyob ze. Cov vaj tse yuav tsum tau tsim rau hauv lub nplhaib-zoo li cov yeeb nkab network.
4. Tsis txhob muaj kev ywj pheej los yog dej me me ntawm cov kav dej ntev ntev ntawm lub cev. Xws li ib qho kev npaj yuav ua rau ib feem ntawm lub raj xa dej rau lub sijhawm ntev nyob rau hauv qhov dej ntws tsis tu ncua lossis ib nrab-stagnant flow xeev, yooj yim ua rau corrosion ntawm lub raj xa dej.
5. Txhawm rau zam los yog txo qis galvanic corrosion, hauv cov kav dej tooj liab, tsis txhob txuas cov pa roj carbon zoo tib yam. Yog tias muaj, rwb thaiv tsev yuav tsum tau ua ntawm kev sib txuas. Copper flange thiab steel flange kev twb kev txuas, cov khoom uas tsis yog tooj liab zawj connectors ntawm lub zawj, yuav tsum nyob rau hauv nws kev sib cuag nrog cov khoom siv tooj liab, coj cov kev ntsuas tsim nyog rau kev tiv thaiv corrosion. Pom zoo piping system tag nrho siv tooj liab (xws li tooj liab li qub thiab tooj liab alloy txhawb qhov chaw, thiab lwm yam). Electrochemical corrosion ntawm hlau feem ntau yog vim muaj CO2, SO2, NH2, O2 thiab lwm yam khoom nyob rau hauv cov huab cua, thiab muaj plua plav, corrosion thiab nti ntawm cov kav dej. Thiab cov khoom siv hlau sib txawv muaj qhov sib txawv, cov tshuaj muaj pes tsawg leeg thiab cov koom haum sab hauv ntawm cov khoom sib txawv. Thaum muaj cov tshuaj electrolyte rau ntawm qhov chaw sib cuag, cov hlau atoms feem ntau poob electrons thiab oxidized thiab corroded. Lus Cim: Qhov kev ntsuas no feem ntau yog los tiv thaiv galvanic corrosion ntawm carbon steel sab. Copper sab ntawm lub electrode muaj peev xwm ntawm tooj liab tsis yooj yim rau plam electrons, yog li nws tsis yooj yim rau corrode.
6. Ntshav tooj liab yeeb nkab yuav tsum tsis txhob muab nchuav rau hauv cov pob zeb muaj zog. Ntxiv rau qhov nyuaj brazing thiab clamping hom kev sib txuas ntawm cov yeeb nkab tooj liab, qhov seem ntawm txoj kev txuas cov yeeb nkab tooj liab yuav tsum tsis txhob muab zais rau hauv cov phab ntsa groove lossis hauv av txaj. Kev tsim kho cov txheej txheem kev tsim vaj tsev, kev ua haujlwm ntau zaus, kev tsim kho thiab zais kev tsim kho zoo saib xyuas, cov yeeb nkab siab sim nyuaj, yog tias cov yeeb nkab tau faus rau hauv cov khoom siv ntxiv, ib zaug cov yeeb nkab phab ntsa tawg, kho cov teeb meem. Yog li ntawd, cov kev cai ntawm cov kav dej tooj liab yuav tsum tsis txhob muab nchuav rau hauv cov pob zeb uas muaj zog, cov slabs, kab.
7. faus tooj liab yeeb nkab yuav tsum yog yas-coated tooj liab yeeb nkab. Vim yog cov kav dej tooj liab rau cov yeeb nkab uas muaj phab ntsa nyias, tso ncaj qha rau hauv cov khoom siv rov qab, pom zoo kom siv cov yas-coated tooj liab yeeb nkab, kom tsis txhob muaj av corrosion ntawm cov yeeb nkab tooj liab acid los yog alkali corrosion los yog cov khoom tawv ntawm cov kav dej los ntawm cov neeg kho tshuab. kev puas tsuaj. Qhov faus qhov tob ntawm faus tooj liab yeeb nkab yuav tsum tau txiav txim siab los ntawm nws cov load sab saud. Hauv cov cheeb tsam txias, sab saum toj ntawm cov yeeb nkab yuav tsum nyob hauv qab kab Frost.
8. Nyob rau hauv lub tsev yeeb nkab yuav tsum tau muab tso rau kab rov tav los yog ntsug dabtsi yog khoov rau hauv lub tsev. Copper yeeb nkab thermal expansion system, khoov rau hauv tsev, tuaj yeem tshem tawm qhov kev ntxhov siab los ntawm kev nthuav dav ntawm cov kav dej.
9. Cov kav dej hauv pem teb, cov phab ntsa thauj khoom, yuav tsum muaj lub casing. Kev teeb tsa lub casing hauv pem teb, qhov qis kawg yuav tsum tau yaug nrog hauv pem teb, sab saum toj yuav tsum yog 20 ~ 50mm saum toj no hauv pem teb. installation ntawm casing nyob rau hauv lub phab ntsa, qhov kawg ntawm cov hniav nto thiab tiaj tus.
10. chav dej, chav ua noj thiab lwm yam dej faib ceg, nyob rau hauv lub tsev hauv pem teb matting los yog phab ntsa grooves yuav siv tau nyob rau hauv parallel, series faib dej distributor. Tsis pub tshem tawm fittings nyob rau hauv cov dej distributor yeeb nkab. Yas-coated tooj liab yeeb nkab yog haum. Piv nrog rau cov kev faib dej ib txwm muaj, cov dej faib dej faib cov kev pab cuam muaj cov hydraulic zoo, txhim kho cov dej ruaj ntseg, kev tsim kho thiab kev teeb tsa yooj yim, tab sis nyob rau hauv cov dej distributor yuav tsum tau muab tso rau ntawm qhov tso tawm valve.
