Cov yeeb nkab fittings yog cov khoom tseem ceeb hauv cov kav dej thiab kev thauj cov kua tsheb, thiab xaiv cov khoom zoo yog qhov tseem ceeb rau kev ua tau ntev thiab kev ua tau zoo. Ntawm cov khoom siv feem ntau yog PVC (polyvinyl chloride), PE (Polyethylene), thiab PPR (polypropylene random random copolymer). Txhua ntawm cov ntaub ntawv no muaj cov khoom uas sib txawv uas ua rau lawv haum rau cov ntawv thov tshwj xeeb. Kab lus no piv rau cov yam ntxwv ua kom zoo ntawm PVC, PE, thiab PPR yeeb nkab fittings los ntawm ntau qhov kev xav.
1. Cov Khoom Siv Khoom Siv thiab Tshuaj Lom Zem
PVC cov yeeb nkab fittings paub txog lawv cov tshuaj zoo heev thiab nruj. Lawv tau dav siv nyob rau hauv kev ua kua, dej, thiab ua haujlwm siv tshuaj lom neeg vim lawv lub peev xwm tiv taus cov kua qaub, alkalis, thiab ntsev. PE fittings, tshwj xeeb yog HDPE, muab kev cuam tshuam zoo heev thiab hloov tau yooj yim, uas ua rau lawv haum rau hauv av dej thiab roj pipelines. PPRings, ntawm qhov tod tes, muaj kev phom sij heev rau kev siv tshuaj lom thiab kub thiab txias rau cov dej sov thiab txias dua.
2. Qhov kub thiab qhov siab ua tau zoo
PPRictings outperform ob txhais tau PVC thiab PE nyob rau high - qhov chaw ib puag ncig. Lawv tuaj yeem tiv tauj qhov chaw tas mus li ntawm 95℃thiab tswj kev ua ncaj ncees nyob rau hauv high} kev faib dej kub thiab kev lag luam kub kub. PVC fittings, thaum muaj zog ntawm chav sov, zoo li ua brittle ntawm tsawg kub thiab muag thaum nce kub. PE fittings muaj qhov qis qis - kub ua tau tab sis yog tsis haum rau high- qhov kev thov kub piv rau PPR.
3. Kev teeb tsa thiab cov txheej txheem sib tham
PVC Fittings feem ntau siv cov kuab tshuaj vuam rau kev sib txuas, uas tsim kev sib txuas tas mus li tab sis yuav tsum tau qhov cua nyob ruaj khov thiab yuav tsum tau ua kom dav dav thiab yuav tsum tau ua kom dav dav thiab yuav tsum tau qhov kev tawm tsam kom zoo thiab yuav tsum tau ua kom dav dav thiab yuav tsum tau qhov cua nyob rau hauv kev teeb tsa. PE fittings feem ntau koom nrog siv pob tw fusion lossis kev siv hluav taws xob, muab cov pob qij txha ruaj thiab tso cov khoom siv tshwj xeeb. PPR fittings siv kev ntsuas fusion thaum tshav Fusion Rusion thiab ntev thiab ntev}}}} kav sib txuas nrog kev pheej hmoo ntawm qhov tsis muaj kev phom sij tsawg. Ntawm peb, PPR kev teeb tsa feem ntau qhuas rau lawv txoj kev ua tau zoo thiab kev ntseeg tau hauv ob qho chaw nyob thiab cov dej kav dej.
4. Lub Neej thiab Kev Pab Cuam Xwm
Hais txog lub sijhawm ntev, pPR fittings muaj cov haujlwm zoo dua nrog kev pabcuam lub neej ntawm ntau dua 50 xyoo raws li kev ua haujlwm. PE fittings tseem muaj ntev - sij hawm kev ntseeg tau, tshwj xeeb yog nyob rau hauv saj zawg zog thiab faus. PVC fittings, thaum ntev {{{}}}} kav hauv ntau cov chaw, tuaj yeem txwv nyob rau hauv UV kis lossis nrog rov ua dua tshiab cycling. Yog li ntawd, rau cov ntawv thov uas xav tau ntev- lub sij hawm ruaj khov thiab kev tu tsawg, PP thiab PE zoo dua li PVC.
5. Kev cuam tshuam ib puag ncig thiab kev nyab xeeb
PPR thiab PE fittings raug suav tias yog ntau tus phooj ywg zoo thiab muaj kev nyab xeeb rau kev haus dej. Lawv muaj kev ywj pheej ntawm cov hlau hnyav thiab cov yas qhwv thiab tsis txhob ua kom muaj kev phom sij. PVC, thaum rov ua dua tshiab, tuaj yeem muaj cov tshuaj ntxiv ntxiv xws li cov tshuaj chlorine thiab stabilizers uas tau hais cov kev txhawj xeeb nyob rau qee cov ntawv thov uas rhiab. Los ntawm cov kev ruaj khov thiab kev noj qab haus huv xam pom, pPr fittings sawv tawm ntawm lawv cov tsis} pakuv, tsw ib puag ncig thaum kev tsim khoom thiab siv.

PVC, PE, thiab PPR yeeb nkab txhua qhov tseem ceeb txoj haujlwm hauv cov khoom thauj hauv dej, tab sis lawv lub nra tau yog nyob ntawm qhov kev xav tau ntawm peb tes num. PVC muaj tus nqi -} kev daws teeb meem rau cov tsis muaj zog, thaum muaj kev sib xyaw nyob rau hauv dej kub, high {} h siab} pa taws. Nkag siab txog qhov ua tau zoo thiab kev txwv pab cov khoom lag luam engineers thiab cov neeg cog lus tau muab kev txiav txim siab txhim khu kev qha thiab muaj txiaj ntsig piping daws teeb meem.
