Qee cov ntsiab lus tseem ceeb txog cov yeeb nkab tooj liab
Cov kav dej tooj liab thiab cov khoom siv tooj liab feem ntau yog siv hauv cov kav dej, cua sov thiab cov kav dej. Hauv qab no, cov tuam ntxhab ntawm cov yeeb nkab tooj liab txuas ceev, cov kav dej tooj liab thiab cov kav dej tooj liab yuav tham txog qee cov ntsiab lus tseem ceeb ntawm cov yeeb nkab tooj liab fittings:
1. Kev xaiv cov khoom siv: Kev xaiv cov khoom siv tooj liab yog qhov tseem ceeb heev. Cov kav dej tooj liab feem ntau yog ua los ntawm ntau qib tooj liab xws li Copper Tube Hom K, Hom L lossis Hom M. Qhov kev xaiv tshwj xeeb yog nyob ntawm lub hom phiaj thiab qhov xav tau ntawm cov yeeb nkab.
2. Cov qauv kev tsim khoom: Cov kav dej tooj liab thiab cov yeeb nkab tooj liab yuav tsum ua raws li cov qauv tsim khoom, xws li ASTM B88 (seamless copper pipe), ASTM B280 (welded copper pipe), ASTM B75 (tooj liab fittings), thiab lwm yam. Xyuas kom meej tias cov khoom yuav khoom ua tau raws li cov qauv tsim nyog los xyuas kom meej qhov zoo thiab kev ua tau zoo.
3. Kev ceev faj txog kev txhim kho: Thaum txhim kho cov kav dej tooj liab thiab cov yeeb nkab tooj liab fittings, xyuas kom cov kev txiav thiab kev sib koom ua haujlwm yog qhov tseeb thiab meej los tiv thaiv cov dej los yog lwm yam teeb meem. Siv cov cuab yeej tshaj lij thiab cov txheej txheem los txiav, koom thiab vuam.
4. Anti-corrosion: Txawm hais tias tooj liab muaj qhov zoo corrosion kuj, corrosion kuj tseem tuaj yeem tshwm sim nyob rau hauv qee qhov xwm txheej, xws li raug rau acidic lossis alkaline ib puag ncig. Nyob rau hauv cov ntaub ntawv no, yuav tsum tau ntxiv kev tiv thaiv corrosion, xws li siv cov txheej tshwj xeeb los yog ntxiv cov ntaub ntawv tsis.
5. Kev tu thiab tu: Txheeb xyuas cov kav dej tooj liab thiab cov kav dej tooj liab tsis tu ncua kom paub tseeb tias tsis muaj qhov xau lossis puas. Thaum ntxuav cov kav tooj liab, siv cov tshuaj ntxuav thiab cov cuab yeej tsim nyog thiab tsis txhob siv cov tshuaj ntxuav tes uas acidic lossis alkaline dhau lawm.
6. Thermal expansion thiab contraction: tooj liab yuav nthuav dav thiab cog lus thaum kub hloov, yog li qhov no yuav tsum tau xav txog thaum tsim thiab txhim kho cov kav dej kom tsis txhob muaj kev ntxhov siab ntau dhau ntawm cov kav dej.
7. Dej zoo: Cov dej zoo cuam tshuam rau corrosion kuj ntawm cov kav dej tooj liab. Yog tias cov dej tsis zoo muaj ntau yam tshuaj los yog impurities, kev ntsuas dej yuav tsum tau txiav txim siab los tiv thaiv cov kav dej tooj liab.
8. Kev tiv thaiv ib puag ncig: tooj liab yog cov khoom siv rov ua dua tshiab, yog li thaum muab cov kav tooj liab thiab cov fittings pov tseg, cov khoom siv rov ua dua tshiab thiab kev kho mob tsim nyog yuav tsum tau ua kom txo qis kev cuam tshuam ib puag ncig.
