Brass Tube
Brass yeeb nkab, ib yam ntawm cov yeeb nkab uas tsis yog-ferrous hlau, yog ib tug nias thiab kos seamless yeeb nkab. Cov yeeb nkab tooj liab muaj cov yam ntxwv ntawm kev ua kom muaj zog thiab tiv taus corrosion, thiab 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. Cov kav dej tooj dag yog cov kav dej zoo tshaj plaws.
Cov yeeb nkab tooj dag muaj cov yam ntxwv ntawm kev ua kom muaj zog thiab tiv taus corrosion, thiab 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. Cov yeeb nkab tooj liab muaj ntau qhov zoo hauv ib qho: nws muaj zog thiab muaj lub zog siab ntawm cov hlau dav dav; Nyob rau tib lub sijhawm, nws yooj yim dua rau khoov, ntswj, tawg thiab tawg dua li cov hlau dav dav, thiab muaj qee yam tsis kam tiv thaiv te heave thiab cuam tshuam. Yog li ntawd, ib zaug cov kav dej tooj liab nyob rau hauv cov khoom siv dej ntawm lub tsev tau teeb tsa, nws muaj kev nyab xeeb thiab txhim khu kev ntseeg siv, thiab txawm tias tsis tas yuav tu thiab tu.
Qhov zoo ntawm cov yeeb nkab tooj dag: Cov yeeb nkab tooj liab yog qhov nyuaj, tsis yooj yim rau corrode, thiab tiv taus qhov kub thiab txias, thiab tuaj yeem siv rau ntau qhov chaw. Hauv kev sib piv, qhov tsis zoo ntawm ntau lwm cov kav dej yog pom tseeb. Piv txwv li, cov kav dej galvanized steel siv hauv tsev yav dhau los yog yooj yim heev rau xeb. Tom qab siv sijhawm luv luv, cov kais dej yuav tig daj thiab cov dej ntws yuav txo qis. Qee cov ntaub ntawv yuav txo tau lawv lub zog sai ntawm qhov kub thiab txias, uas yuav ua rau muaj kev phom sij tsis zoo thaum siv 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.
Brass yeeb nkab: hnyav ib 'meter'=0.02670 * phab ntsa thickness * (sab nraud txoj kab uas hla-phab ntsa thickness)
Cov kav dej tooj liab rau cov khoom siv hluav taws xob, cov kav dej tooj liab rau cov tub yees, cov kav dej muaj zog tooj liab, cov kav dej tiv thaiv corrosion, cov kav dej tooj liab rau kev sib txuas, cov kav dej tooj liab rau cov kav dej, hluav taws xob cua sov tooj liab kav, thiab cov kav dej tooj liab muaj.
Cov kav dej tooj dag yog lub teeb hauv qhov hnyav, muaj cov thermal conductivity zoo, thiab muaj lub zog qis-kub. Lawv feem ntau siv los tsim cov khoom siv hluav taws xob sib pauv (xws li condensers, thiab lwm yam). Lawv kuj tau siv los sib sau cov kav dej kub qis 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 raws li ntsuas cov kav dej rau cov twj paj nruag. Brass tubes muaj zog thiab corrosion-resistant.
Lawv muaj qhov zoo hauv qab no: cov raj tooj liab yog ib qho nyuaj, tsis yooj yim rau corrode, thiab tiv taus qhov kub thiab txias, thiab tuaj yeem siv rau ntau qhov chaw uas tsis yog tooj liab. Piv nrog rau tooj dag, ntau lwm cov kav dej muaj qhov tsis zoo. Piv txwv li, galvanized steel kav, uas tau siv ntau zaus hauv cov tsev nyob yav dhau los, yooj yim heev rau xeb. Tom qab siv sijhawm luv luv, cov teeb meem xws li yellowing ntawm kais dej thiab txo cov dej ntws yuav tshwm sim. Qee cov ntaub ntawv yuav txo tau lawv lub zog sai ntawm qhov kub thiab txias, uas yuav ua rau muaj kev phom sij tsis zoo thaum siv cov kav dej kub. Txawm li cas los xij, vim qhov kub ntawm qhov kub ntawm cov tooj liab, uas yog siab li 1083 degrees, qhov kub ntawm cov dej kub yog qhov cuam tshuam rau cov raj tooj liab. Cov khoom siv tooj dag muaj xws li tooj dag raj rau cov khoom siv hluav taws xob, tooj dag raj rau cov tub yees, cov khoom siv hluav taws xob siab siab, cov hlau tsis muaj zog corrosion, cov raj tooj dag rau kev sib txuas, cov raj tooj liab rau cov dej, hluav taws xob cua sov tooj dag, thiab tooj dag raj rau kev lag luam.
