** 1. Dab tsi yog qhov sib txawv ntawm cov yeeb nkab steel thiab lub galvanized steel yeeb nkab? **
* ** Cov yeeb nkab steel: ** Qhov no yog liab qab cov yeeb nkab steel hlau nrog tsis muaj txheej tshwj xeeb. Nws yog qhov ua rau muaj xeb thiab xeb thaum raug cov dej noo lossis oxygen rau saum huab cua lossis dej.
* ** GRANVANIZED STEEL YEE: ** Qhov no yog cov yeeb nkab steel hlau uas tau muab tso nrog ib txheej ntawm zinc. Qhov kev tiv thaiv zinc no ua rau muaj kev tiv thaiv kev tiv thaiv thiab muab zinc corrodes (zinc corrodes (cov tuab sich hauv qab) los tiv thaiv cov hlau hauv qab los ntawm xeb. Cov txheej txheem Galvanization yog ib txwm ua los ntawm kub- ntsw cov yeeb nkab rau hauv Molten Zinc.
** 2. Kuv yuav paub tau li cas yog tias kuv muaj galvanized steel kav? **
* ** Kev tshuaj xyuas kev pom: ** Saib rau tus yam ntxwv ua pov thawj, crystalline - Zoo li qauv hu ua "Tsiaj." Cov xim feem ntau yog matte grey lossis silvery {2 {grey} grey.
* ** PEM TSAM (ua tib zoo): ** maj mam khawb ib thaj chaw tsis muaj peev xwm. Hauv qab cov grey / nyiaj saum npoo av, koj yuav tsum pom ci, ci iab silm. Yog tias koj pom npub, txho tsaus grey lossis reddish - xim av (xeb), nws zoo li cov hlau lossis xeb galvanized.
* ** MOTERET TEST: ** Ob qho tib si sib xws thiab cov hlau galvanized yog sib nqus. Yog tias cov hlau nplaum hlau nplaum muaj zog, nws yog cov hlau (tog twg los tsis tu ncua lossis galvanized). Yog tias nws tsis lo, nws yog cov tooj liab, yas (PVC / CPVC), lossis PEX.
* ** Saib cov fittings: ** galvanized cov yeeb nkab xov thiab fittings kuj muaj tib lub zinc txheej thiab tus yam ntxwv grey / nyiaj tsos.
* ** Hnub nyoog ntawm lub tsev: ** Yog tias koj lub tsev tau tsim ua ntej xyoo 1960 2}}}}} pakuv (tsis yog tooj liab hlau (tsis txhob tooj liab hlau heev galvanized.
* ** Txiav tawm sab nraud (rhuav tshem): ** Yog tias koj txiav cov yeeb nkab, cov roj av sab hauv, tshwm sim} grey thaum cov kav dej tshiab yuav ua rau xeb tsim hauv).
** 3. Dab tsi yog qhov tsis zoo ntawm Galanized steel kav? **
* ** QIB Corrosion thiab xeb tsim tsa: ** Tshaj lawm ntau xyoo, zinc txheej sab hauv cov yeeb nkab hluav taws xob, thiab cov kab hauv qab steel xeb. Qhov no xeb accumulates, nqaim nqaim cov yeeb nkab lub inner iner ("nplai" tsim tau dej siab thiab ntws.
* ** Muaj peev xwm rau cov dej xau: ** Raws li xeb kev ua siab sab hauv, nws tuaj yeem tsim cov pob hluav taws xob tsis sib xws thiab cov ntoo tawg lossis cov raj tawg, tshwj xeeb ntawm cov pob qij txha, tshwj xeeb tshaj yog ntawm pob qij txha thiab fittings.
* ** Cov teeb meem dej zoo: ** Ruste flues tuaj yeem sib tsoo xoob, ua rau cov dej xim av lossis xim liab. Cov kav dej siab tshaj plaws galvanized cov kav dej yuav muaj txhuas nyob hauv cov txheej txheem zinc
* ** LOJ LAB NTAWD: ** Thaum zinc txuas ntxiv lub neej, galvanized kav dej feem ntau kawg 40-70 xyoo (muaj tsawg dua li tooj liab lossis yas.
* ** Kev ua haujlwm nyuaj: ** TXIAV THIAB xov qub, xeb galvanized flavanized yog qhov nyuaj. Txuas nws txoj kev ntseeg siab rau cov ntaub ntawv tshiab (zoo li tooj liab lossis yas) yuav tsum tau hloov cov fittings tshwj xeeb.
* ** NTXIV Kev txhuam hniav ntxiv: ** Cov ntxhib sab hauv qhov chaw tshwm sim los ntawm cov dej ntws tsis kam mus rau cov dej ntws ntau dua li cov luam dej zoo li tooj liab lossis yas.
** 4. Yog galvanized steel yeeb nkab ok rau dej? **
* ** Yog siv: ** Yog, Galvanized steel yeeb nkab yog cov qauv khoom siv rau ntau xyoo (haus) cov kab / twv (DWV) hauv tsev thiab vaj tse.
* ** Qhov kev pom zoo niaj hnub - feem ntau tsis pom zoo: **
* ** Rau tshiab Installations: ** Nws yog ** tsis pom zoo ** rau cov dej tso dej tshiab, tshwj xeeb cov dej haus. Cov ntaub ntawv niaj hnub zoo li tooj liab, Pex, lossis CPVC yog qhov xav tau vim yog lub neej ntev dua, cov kev pheej hmoo smoother, thiab txo qis kev pheej hmoo.
* ** Rau cov kab ke tam sim no: ** Ntau lub tsev qub qub tseem muaj ua haujlwm galvanized kav dej. Thaum nws * muaj peev xwm * Cov khoom siv tsis zoo (txo cov dej ntws, tshwj xeeb tau ua kom muaj cov dej tsis huv, tshwj xeeb yog rau cov dej haus, thaum ua tau lossis thaum muaj teeb meem tshwm sim. Nws yog feem ntau suav hais tias tsis muaj cai rau cov dej tshiab.
** 5. Yuav galvanized steel xeb hauv dej? **
* ** Yog, nws thiaj li nws yuav xeb hauv dej. ** Zinc txheej muab kev tiv thaiv zoo heev * thaum xub thawj *. Txawm li cas los xij, sijhawm dhau sijhawm (feem ntau xyoo corrodes kev txi thiab maj mam hnav, tshwj xeeb yog nyob rau thaj chaw uas muaj kev txhoj puab heev (acidic lossis nyuaj) dej. Thaum cov zinc yog depleted nyob rau hauv me me, lub pib siv cov hlau yog tshwm sim rau dej thiab oxygen thiab yuav pib xeb. Internal xeb tsim yog qhov tseem tsis ua hauj lwm hom ntawm galvanized dej kav dej. Thaum lub zinc coating ho rustays qeeb piv rau cov hlau liab qab, nws tsis tiv thaiv nws tas mus li thaum tas li.
