Txheej txheem cej luam ntawm cov yeeb nkab hlau alloy

Cov Yeeb Nkab Hlau Alloy yog siv rau hauv cov ntawv thov uas xav tau cov khoom tiv taus corrosion nruab nrab nrog kev ruaj khov zoo thiab tus nqi pheej yig. Hais yooj yim, cov yeeb nkab alloy yog qhov nyiam dua hauv cov cheeb tsam uas cov yeeb nkab carbon yuav tsis ua haujlwm. Muaj ob chav kawm ntawm cov hlau alloy - cov hlau alloy siab thiab cov hlau alloy qis. Cov yeeb nkab uas tsim cov hlau alloy qis muaj cov ntsiab lus alloying uas ntau dua 5%. Thaum cov ntsiab lus alloying ntawm cov hlau alloy siab yuav ntau ntawm 5% txog li 50%. Zoo ib yam li feem ntau cov hlau alloy lub peev xwm ua haujlwm siab ntawm Cov Yeeb Nkab Hlau Alloy Seamless yog li 20% siab dua li cov yeeb nkab welded. Yog li hauv cov ntawv thov uas muaj kev ua haujlwm siab dua ua qhov yuav tsum tau ua ua ntej, kev siv cov yeeb nkab seamless yog qhov tsim nyog. Txawm hais tias muaj zog dua li cov yeeb nkab welded, tus nqi yog siab dua. Ntxiv mus, qhov kev pheej hmoo ntawm kev xeb intergranular ntawm thaj chaw kub cuam tshuam weld yog ntau dua hauv cov khoom welded. Qhov sib txawv pom ntawm Cov Yeeb Nkab Hlau Alloy Welded thiab cov khoom seamless yog qhov latitudinal seam raws qhov ntev ntawm cov yeeb nkab. Txawm li cas los xij, niaj hnub no, nrog kev nce qib hauv thev naus laus zis, qhov sib txuas ntawm Alloy Steel ERW Pipe tuaj yeem txo qis ntau los ntawm kev kho qhov chaw, xws li nws tseem tsis pom rau tib neeg lub qhov muag.
