Brief kev taw qhia
Ductile hlau yeeb nkab yog ib hom cam khwb cia hlau yeeb nkab.Nyob rau hauv cov nqe lus ntawm qhov zoo, spheroidization qib ntawm cam khwb cia hlau yeeb nkab yuav tsum tau tswj mus rau 1-3 qib (spheroidization tus nqi> 80%), yog li cov neeg kho tshuab khoom ntawm cov khoom nws tus kheej tau zoo dua, nrog rau cov xwm ntawm hlau thiab cov khoom. cov khoom steel.Lub metallographic qauv ntawm lub annealed ductile hlau yeeb nkab yog ferrite ntxiv rau ib qho me me ntawm pearlite.Nws muaj cov khoom siv zoo, zoo heev corrosion kuj, zoo ductility, zoo sealing nyhuv, yooj yim installation, thiab yog tsuas yog siv rau cov dej, roj, kis tau tus mob, thiab lwm yam nyob rau hauv lub nroog, industrial thiab mining lag luam.
Ib qho nyiaj ntawm spherical graphite yog faib rau ntawm ferrite thiab pearlite matrix.Raws li qhov sib txawv nominal txoj kab uas hla thiab yuav tsum tau rau elongation, qhov feem ntawm ferrite thiab pearlite nyob rau hauv lub matrix qauv yog txawv.Qhov kev faib ua feem ntawm pearlite nrog me me txoj kab uas hla feem ntau tsis ntau tshaj 20%, thiab qhov loj ntawm txoj kab uas hla yog feem ntau tswj ntawm li 25%.
Pkev ua tau zoo ntawm dcev ucile
Cov yeeb nkab hlau yog ib hom cam khwb cia hlau, uas yog cov hlau alloy, carbon thiab silicon.Graphite nyob rau hauv spheroidal graphite cam khwb cia hlau muaj nyob rau hauv daim ntawv ntawm spheroidal graphite.Feem ntau, qhov loj ntawm graphite yog 6-7, thiab spheroidization qib ntawm cam khwb cia yeeb nkab yuav tsum tau tswj kom 1-3 (spheroidization tus nqi ≥ 80%) nyob rau hauv cov nqe lus ntawm zoo.Yog li ntawd, cov khoom siv ntawm cov khoom siv nws tus kheej tau zoo dua qub, nrog rau cov xwm txheej ntawm cov hlau thiab cov khoom ntawm cov hlau.Cov qauv metallographic ntawm cov yeeb nkab annealed ductile hlau yog ferrite ntxiv rau ib qho me me ntawm pearlite, thiab nws cov khoom siv tau zoo.
Cov yeeb nkab hlau yog feem ntau hu ua centrifugal ductile hlau yeeb nkab.Nws muaj cov yam ntxwv ntawm hlau, kev ua tau zoo ntawm cov hlau, zoo heev corrosion kuj, zoo ductility, zoo sealing nyhuv, yooj yim installation, thiab yog tsuas yog siv rau cov dej, roj, kis tau tus mob, thiab lwm yam nyob rau hauv lub nroog, industrial thiab mining qhauj.Nws yog thawj qhov kev xaiv ntawm cov kav dej xa dej nrog cov nqi siab.Piv nrog PE yeeb nkab, lub sij hawm installation ntawm ductile hlau yeeb nkab yog yooj yim dua thiab sai dua PE yeeb nkab, thiab sab hauv thiab sab nraud bearing siab yog zoo dua tom qab installation;Los ntawm qhov kev xav ntawm airtightness thiab corrosion kuj, lub airtightness ntawm spheroidal graphite yeeb nkab tom qab installation yog zoo dua, thiab corrosion kuj tseem tuaj yeem txhim kho los ntawm ntau yam kev tiv thaiv corrosion;Los ntawm qhov kev ua haujlwm hydraulic ntawm qhov pom, vim hais tias cov ntsiab lus ntawm cov yeeb nkab hlau feem ntau yog hais txog lub puab kab uas hla, qhov tshwj xeeb ntawm PE yeeb nkab feem ntau yog hais txog sab nraud, vim hais tias nyob rau hauv tib lub ntsiab lus, cov yeeb nkab hlau tuaj yeem ua tiav ntau dua;Los ntawm qhov kev xav ntawm kev txhim kho thiab kev saib xyuas cov nqi, cov yeeb nkab hlau yeeb nkab muaj cov nqi zoo dua.Sab hauv phab ntsa yog txau nrog zinc, cement mortar anti-corrosion cov ntaub ntawv, thiab lwm yam.

Cov lus qhia xaiv ntawm dcev ucile
1. Kev xaiv cov kav hlau kav hlau yuav tsum yog raws li cov xwm txheej tshwj xeeb ntawm qhov chaw tso, thiab cov ntawv sib txuas ntawm cov kav dej ncaj thiab cov fittings yuav tsum raug xaiv.
2. Lub nplhaib roj hmab feem ntau yog ua los ntawm NBR, SBR, EPDM thiab lwm yam ntaub ntawv.
3. Kev xaiv txheej txheej: xaiv cov txheej tsim nyog raws li cov txheej txheem sab hauv thiab sab nraud thaum siv.Cov txheej txheem sab hauv uas twb muaj lawm yog epoxy resin, polyurethane txheej sab hauv thiab sab nraud, PE zaj duab xis txheej thiab lwm yam khoom tshiab ntawm cov yeeb nkab hlau, thiab nws cov kev ua tau zoo yuav tsum tau nkag siab meej thaum xaiv.
Qhov zoo thiab qhov tsis zoo ntawm dcev ucile
Aua dvant
Cov kav dej hlau siv tau siv hauv cov kav dej nruab nrab thiab tsis tshua muaj siab (feem ntau siv qis dua 6MPa).Cov kav hlau kav dej muaj kev nyab xeeb thiab txhim khu kev qha, kev puas tsuaj tsawg, kev tsim kho yooj yim thiab ceev ceev, thiab zoo heev corrosion kuj.Txoj kev tsim tshiab "Yandun" series pipeline tuaj yeem siv rau kev tsim kho tsis muaj trench thiab dav siv hauv kev tsim cov kav dej hla dej, txoj kev thiab vaj tse.Lub "Saizin" series pipeline siv tshwj xeeb zinc aluminium alloy sab nraud txau txheej txheem los txhim kho corrosion kuj ntawm cov kav dej ob peb zaug, thiab siv dav hauv kev tsim kho cov av corrosive.
Dyog qhov zoo
Feem ntau, nws tsis yog siv nyob rau hauv high-pressure yeeb nkab network (siab dua 6MPa).Vim tias cov yeeb nkab lub cev hnyav heev, cov tshuab yuav tsum tau siv thaum lub sijhawm teeb tsa.Nyob rau hauv cov ntaub ntawv ntawm cov dej ntws tom qab kev ntsuam xyuas siab, tag nrho cov kav dej yuav tsum tau khawb tawm, cov kav dej yuav tsum tau nqa mus rau qhov siab uas lawv tuaj yeem muab tso rau hauv cov clamps, thiab cov clamps yuav tsum tau muab ntsia kom tiv thaiv cov dej tawm.
