Brass fittings yog siv dav hauv cov kav dej thiab cov kav dej vim lawv cov kav ntev thiab ntau yam. Txawm li cas los xij, nws yog ib qho tseem ceeb kom nkag siab txog lawv qhov ntsuas kub kom ntseeg tau tias muaj kev nyab xeeb thiab ua haujlwm tau zoo. Nyob rau hauv tsab xov xwm no, peb yuav tham txog qhov kub thiab txias txwv ntawm tooj dag fittings kom meej.
1. Kev ua haujlwm kub siab tshaj plaws
Brass fittings muaj qhov siab tshaj plaws ua haujlwm kub uas yuav tsum tsis txhob tshaj. Qhov siab tshaj plaws kub yuav txawv nyob ntawm seb qhov tshwj xeeb alloy muaj pes tsawg leeg ntawm tooj dag. Feem ntau, cov khoom siv tooj dag tuaj yeem tiv taus qhov kub thiab txias txog li 200-250 degrees Celsius ({1}} degrees Fahrenheit). Nws yog ib qho tseem ceeb los xyuas cov chaw tsim khoom tshwj xeeb lossis sab laj nrog tus kws tshaj lij los txiav txim siab qhov kev ua haujlwm siab tshaj plaws rau koj cov khoom siv tooj dag tshwj xeeb.
2. Thermal Expansion thiab Contraction
Brass fittings, zoo li txhua yam hlau, nthuav thiab cog lus nrog kev hloov pauv hauv qhov kub thiab txias. Qhov no thermal expansion thiab contraction tuaj yeem ua rau muaj kev ntxhov siab ntawm cov fittings yog tias lawv raug kub hnyiab heev. Nws yog ib qho tseem ceeb uas yuav tau xav txog qhov no thaum tsim thiab txhim kho cov kav dej siv tooj dag fittings. Kev tso cai tsim nyog yuav tsum tau ua rau thermal expansion thiab contraction kom tsis txhob muaj qhov xau lossis ua tsis tiav.
3. Kev siv kub-kub
Brass fittings tej zaum yuav tsis haum rau cov ntawv thov kub uas qhov kev khiav hauj lwm kub siab tshaj lawv qhov siab tshaj plaws. Nyob rau hauv tas li ntawd, lwm yam ntaub ntawv xws li stainless hlau los yog tshwj xeeb high-temperature alloys yuav tsum tau xav txog. Cov ntaub ntawv no tau tsim tshwj xeeb los tiv thaiv qhov kub siab dua yam tsis muaj kev cuam tshuam rau kev ncaj ncees ntawm cov kav dej.
4. Kev siv qhov kub thiab txias
Tsis zoo li cov kev txwv kub kub, tooj dag fittings ua tau zoo nyob rau hauv cov kev siv uas tsis kub. Brass muaj cov thermal conductivity zoo, tso cai rau nws tswj nws lub zog thiab kev ncaj ncees ntawm cov qauv txawm nyob rau ntawm qhov kub qis. Qhov no ua rau tooj dag fittings haum rau siv nyob rau hauv dej txias system los yog tub yees daim ntaub ntawv uas tsis tshua muaj kub.
5. Kev xav txog lwm yam
Thaum ntsuas qhov ntsuas kub ntawm cov khoom siv tooj dag, nws yog ib qho tseem ceeb uas yuav tau xav txog lwm yam uas yuav cuam tshuam rau lawv cov kev ua tau zoo. Piv txwv li, lub xub ntiag ntawm corrosive tshuaj, high humidity, los yog ntev raug rau huab cua kub yuav ua rau kom corrosion thiab txo tag nrho cov kub tsis kam ntawm tooj dag fittings. Kev saib xyuas tsis tu ncua, kev rwb thaiv tsev kom zoo, thiab kev xaiv cov khoom tsim nyog yog qhov tseem ceeb los xyuas kom lub neej ntev thiab kev ntseeg siab ntawm cov khoom siv tooj dag hauv txhua daim ntawv thov.
Hauv kev xaus, tooj dag fittings muaj qhov kub thiab txias uas yuav tsum tau xav txog kev nyab xeeb thiab ua haujlwm tau zoo. Kev nkag siab txog qhov siab tshaj plaws ntawm kev ua haujlwm kub, thermal expansion thiab contraction, haum rau cov ntawv thov kub lossis qis qis, thiab lwm yam cuam tshuam rau kev ua haujlwm yog qhov tseem ceeb. Los ntawm kev ua raws li cov lus qhia no thiab kev sab laj cov kws tshaj lij thaum tsim nyog, cov khoom siv tooj dag tuaj yeem siv tau zoo nyob rau hauv lawv cov kev txwv kub hauv ntau cov kav dej thiab cov kav dej.
