Corrosion-resistant thiab high-temperature resistant tooj liab raj rau kev xa cov kua dej

Tube tooj liab kuj hu ua liab tooj liab raj.Ib hom yeeb nkab uas tsis yog-ferrous hlau, uas yog nias thiab kos seamless yeeb nkab.Cov yeeb nkab tooj liab muaj cov yam ntxwv ntawm cov hluav taws xob zoo thiab thermal conductivity.Nws yog cov khoom siv tseem ceeb rau cov khoom siv hluav taws xob thiab cov cua sov-dissipating ntawm cov khoom siv hluav taws xob.Nws tau dhau los ua thawj qhov kev xaiv rau cov neeg cog lus niaj hnub los txhim kho cov kav dej, cua sov thiab cua txias kav hauv txhua lub tsev lag luam hauv tsev.Cov kav dej tooj liab muaj zog tiv thaiv corrosion, tsis yooj yim rau oxidize, thiab tsis yooj yim rau chemically react nrog qee cov kua tshuaj, thiab yooj yim rau khoov thiab zoo li.

Cov kav dej tooj liab yog qhov sib dua ntawm qhov hnyav, muaj cov thermal conductivity zoo, thiab muaj lub zog siab ntawm qhov kub thiab txias.Feem ntau siv hauv kev tsim cov khoom siv hluav taws xob sib pauv (xws li condensers, thiab lwm yam).Nws kuj yog siv los sib sau ua ke cryogenic pipelines hauv cov khoom siv oxygen.Cov kav dej tooj liab uas muaj cov kab me me feem ntau yog siv los thauj cov kua uas muaj zog (xws li lub tshuab lubrication, roj siab tshuab, thiab lwm yam) thiab cov raj ntsuas siab rau cov twj paj nruag.

Cim npe

Cov kav dej tooj liab tiv taus qhov kub thiab txias thiab tuaj yeem siv rau ntau qhov chaw.Piv nrog rau qhov no, qhov tsis txaus ntawm ntau lwm cov kav dej yog pom tseeb.Piv txwv li, cov kav dej galvanized steel siv nyob rau hauv cov tsev nyob yav dhau los yog yooj yim heev rau xeb.Yog tias lawv tsis siv sijhawm ntev, yuav muaj teeb meem xws li yellowing ntawm cov kais dej thiab cov dej me me.Kuj tseem muaj qee cov ntaub ntawv uas nws lub zog yuav txo qis ntawm qhov kub thiab txias, uas yuav ua rau muaj kev phom sij tsis zoo thaum siv hauv cov kav dej kub.Lub melting point ntawm tooj liab yog siab li 1083 degrees Celsius, thiab qhov kub ntawm cov dej kub system yog negligible rau tooj liab kav.Archaeologists nrhiav tau ib tug tooj liab kav dej 4,500 xyoo dhau los nyob rau hauv lub Egyptian pyramids, uas yog tseem siv niaj hnub no.

Khoom nta

1) Siv cov txheej txheem nruam nruam thiab dov ntau lawm, siab purity, zoo qauv, tsis tshua muaj oxygen cov ntsiab lus.

2) Tsis muaj pores, trachoma, porosity, nrog zoo thermal conductivity, processability, ductility, corrosion kuj thiab huab cua tsis kam.

3) Yooj yim rau weld thiab braze.

4) Cov khoom lag luam muaj kev ruaj khov zoo, kev kub siab ua haujlwm, siab elongation, thiab kev huv siab, ua tau raws li qhov xav tau ntawm kev huv siab ntawm cov khoom siv tub yees tsis muaj fluorine.
