Qee cov ntsiab lus tseem ceeb txog cov yeeb nkab tooj liab
Copper fittings yog cov cuab yeej siv los koom nrog cov kav dej tooj liab, feem ntau yog ua los ntawm tooj liab lossis tooj liab alloy. Hauv qab no, cov chaw tsim khoom 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:
1. Kev xaiv cov khoom siv: Xaiv cov khoom siv tooj liab zoo lossis tooj liab alloy kom ntseeg tau tias qhov sib koom ua ke muaj lub zog zoo, corrosion kuj thiab kav ntev. Cov khoom siv tooj liab muaj xws li tooj liab C12200 ( tooj liab ntshiab), tooj liab C23000 ( tooj dag), thiab lwm yam.
2. Hom kev sib koom ua ke: Xaiv hom kev sib koom ua ke tsim nyog raws li qhov yuav tsum tau ua ntawm kev sib txuas. Cov feem ntau muaj xws li: kev sib txuas ncaj nraim, kev sib txuas txuas ntxiv, kev sib txuas ntawm threaded, clamp joint, thiab lwm yam. Xaiv hom kev sib koom ua ke tsim nyog raws li qhov tshwj xeeb daim ntawv thov scenario ntawm cov yeeb nkab txuas.
3. Loj thiab Dimensions: Nco ntsoov xaiv qhov haum haum loj kom ua tau raws li cov kab uas hla thiab tuab ntawm cov yeeb nkab tooj liab txuas nrog. Ua kom haum lub lumen loj nrog cov khoom siv tooj liab sib txuas kom muaj kev ruaj ntseg thiab airtight kev sib txuas.
4. Txoj kev sib txuas: Siv txoj kev sib txuas tsim nyog, xws li vuam, kev sib txuas flared, threaded kev twb kev txuas, thiab lwm yam. Raws li qhov xav tau tiag tiag thiab daim ntawv thov scenarios, xaiv txoj kev sib txuas tsim nyog thiab xyuas kom meej tias qhov kev sib txuas yog nruj thiab tsis muaj paug.
5. Sealing: Thaum xaiv cov yeeb nkab tooj liab fittings, ua tib zoo saib seb lawv puas tsim los muab kaw. Qee cov pob qij txha muaj sealing gaskets lossis sealant grooves uas muab kev sib khi zoo dua thiab tiv thaiv cov dej thiab roj.
6. Kev txhim kho thiab kho: Thaum lub sij hawm installation, xyuas kom meej tias cov kav dej tooj liab thiab cov pob qij txha muaj kev ruaj ntseg zoo, siv cov cuab yeej tsim nyog thiab txoj hauv kev kom nruj thiab kho. Zam kev puas tsuaj los ntawm kev nruj dhau los yog siv cov cuab yeej tsis raug.
7. Kev tshuaj xyuas thiab kev saib xyuas: Tsis tu ncua xyuas qhov nruj thiab sealing kev ua tau zoo ntawm cov yeeb nkab tooj liab pob qij txha. Yog tias pom qhov xoob lossis xau, kho lossis hloov nws raws sijhawm.
8. Ua raws li cov qauv: Xaiv cov yeeb nkab tooj liab uas ua raws li cov qauv thiab cov kev qhia tshwj xeeb kom ntseeg tau tias lawv ua tau raws li qhov yuav tsum tau ua thiab kev nyab xeeb. Piv txwv li, ANSI/ASME B16.22 (Standard for Copper and Copper Alloy Welded Joint Pipe Fittings).
