Qhov zoo ntawm PPR kav
PPR pipelines tau loj hlob nyob rau hauv qhov chaw nyob rau hauv lub xyoo. Vim lawv cov txiaj ntsig zoo, cov kav dej no tau siv ntau yam kev siv. Nyeem rau kom pom cov txiaj ntsig loj tshaj ntawm PPR fittings:
1. Resistant rau kub thiab txias
Ib qho ntawm cov laj thawj rau qhov muaj koob npe ntawm cov kav dej PPR yog tias lawv tiv taus cua sov thiab txias. Thaum koj siv PPR yeeb nkab, koj tuaj yeem tau txais kev tso siab ntawm kev teeb tsa yooj yim hauv lub caij txias. Tsis tas li ntawd, PPR cov raj muaj cua sov ua tsaug rau lawv cov thermal conductivity tsawg. Qhov tseem ceeb tshaj plaws, PPR piping tuaj yeem tiv taus qhov hnyav thiab siab ntawm cov dej kub vapor.
2. Kev tu cev tsis muaj tshuaj lom
PPR yeeb nkab tau paub tias muaj kev nyab xeeb vim nws tsis muaj tshuaj lom. Yog li ntawd, nws yog cov yeeb nkab zoo tshaj plaws los siv thaum muab dej ntshiab vim nws yuav tsis ua rau muaj kuab paug. Dab tsi ntxiv, PPR yeeb nkab haum rau tib neeg lub cev thiab ib puag ncig.
3. Kev tiv thaiv kev noj qab haus huv thiab ib puag ncig
Thaum koj siv cov kav dej PPR, koj tsis tas yuav xav txog kev yuav cov kav dej txhua lub sijhawm sai sai. PPR kav dej tuaj yeem tiv taus qhov kub thiab txias thiab yuav tsis tawg nrog kev xa dej. Koj kuj tsis tas txhawj txog cov kav dej xau.
4. Abrasion Resistance
Cov khoom tawv tuaj yeem ua rau cov yeeb nkab hnav. Txawm li cas los xij, thaum koj siv PPR tubing, koj tsis tas yuav txhawj xeeb txog kev hloov pauv vim tias cov khoom nyuaj yuav tsis ua rau PPR tubing. Lub sij hawm yuav tsum tau rau nruab PPR kav kuj yog luv heev. Tsis tas li ntawd, nws yog resistant rau electrolysis.
