Kev faib tawm thiab kev siv cov kav dej

Cov kav dej feem ntau raug faib ua peb pawg raws li qhov loj me: cov khoom siv, cov txheej txheem tsim khoom, thiab kev siv. Cov kav dej hlau sib txawv muaj qhov sib txawv tseem ceeb hauv kev ua tau zoo thiab cov xwm txheej siv tau. Cov kev faib tshwj xeeb yog raws li nram no:
Los ntawm cov khoom siv
Qhov no yog txoj kev faib tawm yooj yim tshaj plaws, txiav txim siab qhov kev ua tau zoo ntawm cov yeeb nkab hlau.
Cov Kav Hlau Cam Khwb
Cov Kav Hlau Grey Cast: Nws yooj yim tawg thiab tsis ruaj khov, tab sis pheej yig. Yav dhau los, lawv tau siv dav rau kev muab dej thiab dej ntws rau pej xeem, thiab kev ywg dej rau kev ua liaj ua teb, tab sis tam sim no maj mam hloov los ntawm cov kav hlau ductile.
Cov Kav Hlau Uas Muaj Qhov: Lub zog ntawm cov hlau cam khwb cia tau txhim kho los ntawm kev kho spheroidization. Lawv lub zog ze rau cov kav hlau, thiab lawv muaj kev tiv thaiv corrosion thiab kev sib tsoo zoo. Lawv yog cov khoom siv yeeb nkab tseem ceeb rau cov kav dej nag hauv nroog thiab cov kav dej phwj thiab cov kav dej xa dej tseem ceeb.
Cov Kav Hlau Uas Muaj Peev Xwm Ua Tau: Feem ntau hu ua "cov kav hlau uas muaj peev xwm ua tau," lawv yog cov mos mos thiab yooj yim rau kev ua, feem ntau yog siv rau kev ua cov khoom siv yeeb nkab (lub luj tshib, tees), es tsis yog rau kev xa dej / roj mus deb.
Cov Kav Hlau
Ua los ntawm hlau, lawv lub zog thiab kev tawv tawv zoo dua li cov kav dej hlau cam khwb cia, nrog ntau hom sub-hom:
Cov Kav Hlau Carbon: Ua los ntawm cov hlau carbon, lawv pheej yig thiab siv dav rau kev muab dej thiab dej ntws, hloov pauv cua sov, thiab kev thauj mus los ntawm cov kua dej hauv kev lag luam dav dav.
Cov Yeeb Nkab Hlau Alloy: Muaj cov khoom sib xyaw xws li chromium, molybdenum, thiab nickel, lawv tiv taus qhov kub siab, siab siab, thiab xeb, thiab siv rau hauv kev lag luam tshuaj lom neeg, fais fab, thiab roj av (xws li kev thauj cov pa kub siab thiab cov xov xwm corrosive).
Cov Kav Hlau Tsis Xeb: Muaj ≥10.5% chromium, lawv muaj kev tiv thaiv xeb zoo heev thiab siv rau hauv kev ua zaub mov, tshuaj, thiab dej hiav txwv desalination, qhov twg xav tau kev huv huv lossis kev tiv thaiv xeb siab.
Los ntawm Cov Txheej Txheem Tsim Khoom
Qhov no feem ntau siv rau cov kav hlau; cov txheej txheem sib txawv cuam tshuam ncaj qha rau lub peev xwm dais siab thiab cov xwm txheej siv tau ntawm cov kav dej.
Cov Kav Hlau Tsis Muaj Qhov Txuas
Yog tsis muaj cov seams vuam, lawv muaj lub zog tag nrho thiab muaj peev xwm tuav tau siab, thiab muab faib ua cov kav hlau kub dov seamless thiab cov kav hlau txias kos seamless:
Cov kav hlau tsis muaj qhov kub dov: Txoj kab uas hla loj dua thiab phab ntsa tuab dua, siv rau kev thauj mus los ntawm cov kua dej siab thiab cov khoom siv kho tshuab;
Cov kav hlau tsis muaj qhov txias: Qhov tseeb siab thiab du nto, siv rau cov twj paj nruag precision, cov tshuab hydraulic, thiab lwm yam. Cov Kav Hlau Welded
Ua los ntawm kev vuam cov hlau phaj lossis cov strips, lawv pheej yig dua li cov kav hlau seamless thiab muab faib ua ob pawg:
Cov kav hlau uas vuam ncaj: Cov kav hlau uas vuam ncaj, thiab lub cheeb ntawm cov kav dej me me. Lawv siv rau kev muab dej thiab dej ntws uas muaj siab qis, cov kav dej roj, thiab cov kav dej conduit;
Cov kav hlau uas vuam ua los ntawm cov kauv: Cov kauv vuam yog cov kauv zoo li tus kauv, nrog lub cheeb loj (txog li ntau tshaj 3 meters), thiab ruaj khov zoo. Lawv siv rau cov kav dej roj hauv nroog thiab cov kav dej loj hauv cov chaw kho dej phwj tuaj.
Kev faib tawm los ntawm kev siv
Muab faib ua pawg raws li qhov xwm txheej ntawm daim ntawv thov thiab cov ntaub ntawv xa tawm, muab qhov tshwj xeeb dua:
Cov kav dej hlau rau kev muab dej thiab kev ntws dej: xws li cov kav dej hlau ductile, cov kav dej ntws hlau uas muaj PVC, thiab cov kav dej carbon steel;
Cov kav hlau rau kev xa roj: xws li cov kav hlau galvanized welded thiab cov kav hlau kauv (yuav tsum tau kho kom tsis txhob xeb);
Cov kav hlau rau cua sov: xws li cov kav hlau uas tiv taus cua sov thiab cov kav hlau uas muaj rwb thaiv tsev (nrog ib txheej rwb thaiv tsev sab nraud);
Cov kav hlau lag luam: xws li cov kav hlau sib xyaw uas tiv taus xeb rau kev siv tshuaj lom neeg thiab cov kav hlau siab tsis muaj qhov txuas rau kev siv roj av.
