1. Dab tsi yog cov ntawv thov tseem ceeb rau galvanized round kav kav?
Cov tseem ceeb ntawm galvanized round round referance, ua rau lawv dav siv nyob rau hauv cov ntawv thov uas muaj dej nyob ntev nrog dej, huab cua, lossis ib puag ncig huab cua.
Hauv kev ua haujlwm ntawm kev ua haujlwm: siv ua cov hluav taws kub hoses, cov kav dej nag, kav dej sov, thiab conduit rau cov qauv steel.
Nyob rau hauv cov chaw tsim khoom hauv nroog
Hauv kev ua liaj ua teb: siv raws li kev ua haujlwm rau cov tsev ntsuab thiab cov kav dej rau kev ua liaj ua teb.
Hauv kev lag luam lag luam: Siv raws li cov kav dej rau cov kua roj (xws li cov kua dej ntshiab) thiab cov qauv kev txhawb nqa kav rau cov khoom siv tshuab.
2. Dab tsi yog qhov sib txawv ntawm Galvanized cov kav dej? Dab tsi yog qhov sib txawv?
Galvanized round pipes yog mas categorized raws li kub {{} {{{1} {{1} {1}- sib txawv yog cov txheej txheem galvanizing thiab corrosion tsis kam.
3. Kuv yuav txheeb xyuas qhov "specifications" ntawm galvanized round pas dej? Piv txwv li, ua li cas "DN100" thiab "φ114 × 4" sawv cev? Muaj ob txoj hauv kev los cim cov specifications ntawm galvanized round round pas dej. Nws yog ib qho tseem ceeb kom paub qhov txawv ntawm "Nominal Dev" thiab "qhov loj me":
DN (Nominal Dev): Qhov no yog "ib qho loj me" ntawm cov yeeb nkab, npaj rau tsim thiab xaiv lub hom phiaj. Nws tsis ncaj qha ncaj qha rau sab nraud lossis sab hauv lub taub. Piv txwv li, "DN100" qhia tias yog cov yeeb nkab nrog cov kabinal ntawm 100 hli, uas feem ntau sib raug rau qhov tseeb ntawm lub cheeb ntawm 114mm (qhov no yuav sib txawv me ntsis ntawm cov qauv sib txawv).
Φ (sab nraud inch × phab ntsa tuab): qhov no yog qhov "ntawm cov yeeb nkab loj" ntawm cov yeeb nkab thiab yog qhov tseeb dua. Piv txwv li, "φ114 × 4" qhia txog qhov sab nraud ntawm 114mm, thiab "4" sawv cev rau ib phab ntsa tuab ntawm 4mm. Sab hauv txoj kab uas hla tuaj yeem suav tau siv cov qauv: sab nraud ntawm lub taub dej (piv txwv li
Thaum kev yuav khoom, cov cav teeb hluav taws xob feem ntau siv "dn"; Txawm li cas los xij, thaum tshawb xyuas qhov ntev ntev, siv "txoj kab uas hla × phab ntsa tuab."
4. Kuv tuaj yeem txiav txim dab tsi zoo ntawm galvanized hloov yeeb nkab? Dab tsi yog cov ntsiab lus tseem ceeb kom nrhiav?
Qhov zoo tuaj yeem raug txiav txim siv peb txoj kev yooj yim: "Saib, coj mus rhaub, thiab kuaj," tsom mus rau cov yeeb nkab zinc thiab cov yeeb nkab steel:
Saib ntawm zinc txheej: high -}} Zoo galvanized palvanizing me ntsis, tev, dub, lossis khawb av loj. Tsawg {- Cov kav dej zoo yog qhov muaj cov chaw uas tsis muaj zinc txheej ("kis hlau hlau), uas tuaj yeem ua rau xeb.
Coj mus rhaub zinc txheej: Siv rab rauj me me rau maj mam coj mus rhaub cov yeeb nkab phab ntsa. Siab -} Cov kav dej zoo muaj cov khoom muaj zog zinc nplaum thiab yuav tsis poob tom qab tapping. Yog hais tias lub zinc txheej nrov nrov tawm tom qab tapping, nws qhia tau ib qho kev sib khi ua tsis muaj zog thiab kev tsis zoo.
Ntsuas qhov ntev thiab phab ntsa thickness: siv tus caliper ntsuas cov taub sab nraud thiab phab ntsa tuab. Siab -} Cov kav dej zoo muaj qhov yuam kev me me (phab ntsa tuab sib txawv feem ntau yog tsawg dua lossis sib npaug rau 0.5 hli). Tsawg - Cov kav dej zoo yuav muaj "Phab ntsa tuab" (cim 4 hli tab sis tsuas yog 3.5mm) 7}} bearing. Tshawb xyuas cov txuj ci: Nug cov khoom muag los muab cov lus qhia ntaub ntawv (piv txwv li, Q235b yog ib qho siab- zoo walks cov khoom). Cov khoom lag luam tiag yuav raug sau npe nrog cov qauv tsim khoom (piv txwv li, GB / T 3091 - welded steel kav rau kev thauj khoom qis dua ").
5. Yuav ua li cas ceev faj yuav tsum tau coj thaum siv galvanized round round kav? Lawv puas xeb?
Galvanized round kav yog tsis "rustproof." Kev siv tsis raug thiab kev txij nkawm tuaj yeem ua rau lawv lifespan. Ob lub ntsiab lus tseem ceeb kom nco ntsoov:
Zam kev ua kom tsis txhob ua rau lub zinc txheej zinc: kom tsis txhob khawb qhov chaw nrog cov cuab yeej ntse. Yog hais tias cov txheej zinc puas tsuaj, sai sai theej tawm anti - xeb pleev xim (tshwj xeeb ntawm cov pob qij txha (tshwj xeeb ntawm cov xeb ntawm kis.
Ua tib zoo saib ib puag ncig ua haujlwm: txawm hais tias corrosion {{free} tiv taus (xws li kev muaj zog txheej (xws li corrode ntawm zinc txheej. Xaiv ib qho corrosion ntau - Cov khoom tiv thaiv (piv txwv li, hlau stainless). Thaum siv sab nraum zoov, tsis tu ncua ntxuav cov hmoov av thiab nce cov dej kom txuas ntxiv nws lifespan.
