Vim li cas malleable steel yeeb nkab fittings muaj nplaum pwm thiab succulent tsis xws luag?

Txhawm rau kom ua tau raws li qhov qub thiab raug siv, tsis yog tsuas yog yuav tsum tau ua qhov zoo ntawm cov yeeb nkab fittings, tab sis kuj yuav tsum muaj qee yam kev ua haujlwm thaum siv. Piv txwv li, cov kav hlau steel yuav tsum tau ntxuav kom huv si ua ntej nkag mus rau hauv lub tank. Qhov tseeb, tsis yog tsuas yog yuav tsum tau ntxuav cov yeeb nkab steel ua ntej nkag mus rau hauv lub tank cia, tab sis nws kuj tsis tsim nyog thiab tsis tsim nyog los ntxuav cov yeeb nkab steel ua ntej nkag mus rau hauv lub tank. Qhov no yog vim tias yuav muaj ntau cov hmoov tshauv ntab hauv cov yeeb nkab malleable steel fittings, thiab qee cov hmoov tshauv ntab yuav nyob rau hauv cov yeeb nkab fittings. Yog tias nws tsis tau ntxuav, nws yuav nkag mus rau hauv lub thoob plating tank, uas yuav tsis tsuas yog ua phem rau cov tshuaj plating, tab sis kuj cuam tshuam rau qhov zoo ntawm txheej.

Malleable steel yeeb nkab fittings, feem ntau hu ua malleable cam khwb cia hlau, yog cam khwb cia rau hauv dawb hlau castings thiab ces malleable thiab annealed. Lub graphite nyob rau hauv lub malleable cam khwb cia hlau ntawm malleable steel yeeb nkab fittings yog nyob rau hauv daim ntawv ntawm flocculents, uas muaj tsawg splitting nyhuv ntawm lub matrix, yog li nws cov cuab yeej cuab tam yog siab dua li ntawm grey cam khwb cia hlau, thiab nws plasticity thiab toughness yog zoo dua, tab sis. malleable cam khwb cia hlau tsis tuaj yeem forged. Cov qauv matrix ntawm malleable cam khwb cia hlau yog txawv, thiab nws cov kev ua tau zoo kuj txawv. Ntawm lawv, lub plawv dub malleable cam khwb cia hlau muaj ntau dua plasticity thiab toughness, thaum pearlitic malleable cam khwb cia hlau muaj zog dua, hardness thiab hnav tsis kam.

Raws li ib qho tseem ceeb haum siv nyob rau hauv cov kav dej, malleable steel yeeb nkab fittings feem ntau nyob rau hauv kev sib cuag nrog dej thiab huab cua, yog li lawv cov corrosion kuj tseem ceeb heev. Malleable steel yeeb nkab fittings feem ntau galvanized rau saum npoo ntawm cov khoom siv los tiv thaiv xeb. Ntawm lawv, galvanizing muab faib ua ob hom: kub galvanizing thiab txias galvanizing.

Distinguished los ntawm cov tsos, vim lub uniformity ntawm lub txias-dip galvanized txheej, nws nto yog ze rau cov khoom ntxhib, thiab muaj qhov tshwj xeeb nto unevenness ntawm cov khoom ntxhib, uas zoo nkaus li du thiab ci. Vim muaj qhov tshwm sim ntawm kev tiv thaiv hluav taws xob, qhov chaw txias-galvanized feem ntau tsis muaj galvanized txheej sab hauv (tshwj tsis yog cov txheej txheem tshwj xeeb galvanized). Txawm li cas los xij, vim tias cov txheej txheem kub-dip galvanized yog qhov lig thiab cov kua dej ntawm cov zinc tsis zoo, cov zinc txheej ntawm qhov kub-dip galvanized yeeb nkab fittings yog tuab heev, thiab vim tias qhov kub-dip galvanized nto. txheej yuav raug oxidized los tsim ib txheej tiv thaiv dawb, xim feem ntau tsaus dua. , thiab qhov smoothness yog deb tsawg tshaj li cov khoom txias plating.

Tseem muaj qee cov tuam txhab lag luam uas siv qee qhov ungalvanized dub qhov chaw los tshuaj tsuag txheej nyiaj hmoov xim rau saum npoo thiab muag lawv li galvanized yeeb nkab fittings. Txoj kev ntawm qhov txawv kuj yog qhov yooj yim heev. Thaum ob lub yeeb nkab fittings yog khob rau ib leeg, cov xim nyiaj hmoov xim ntawm cov yeeb nkab fittings yuav poob. Tsis tas li ntawd, nyob rau hauv cov nqe lus ntawm cov xim, yog hais tias cov nyiaj hmoov xim yeeb nkab fittings tsis poob tawm, cov xim txheej yog ci heev, thaum lub txias-galvanized yeeb nkab fittings yog tsaus thiab ci, thiab feem ntau tsis muaj galvanized txheej sab hauv, thaum lub Kub-dip galvanized yeeb nkab fittings yuav tsaus tom qab lub sijhawm. Tshauv.
