PPR (Random Polypropylene Co-polymer) cov kav dej tau siv dav hauv ntau qhov chaw vim lawv cov khoom zoo heev xws li cov tshuaj tiv thaiv siab thiab ua haujlwm ntev. Hauv tsab xov xwm no, peb yuav qhia txog kev tsim thiab kev siv ntawm PPR yeeb nkab txhawb nqa, nrog rau kev tsom mus rau lawv qhov tseem ceeb thiab hom.
Qhov tseem ceeb ntawm cov yeeb nkab txhawb nqa
Kev txhawb nqa cov yeeb nkab kom zoo ua lub luag haujlwm tseem ceeb hauv kev tswj xyuas kev ncaj ncees ntawm PPR cov kav dej. Lawv pab tiv thaiv kev puas tsuaj los ntawm kev co ntau dhau, thermal expansion, lossis kev ntxhov siab vim deformation. Yog tias tsis muaj kev txhawb nqa txaus, cov kav dej yuav sag lossis hloov, ua rau cov dej ntws, txo qis, lossis kev ua haujlwm tsis ua haujlwm. Yog li ntawd, kev tsim thiab kev siv cov yeeb nkab txhawb nqa yuav tsum tau ua tib zoo txiav txim siab thaum txhim kho PPR piping.
Hom Yeeb Nkab Txhawb
Muaj ntau ntau hom kev txhawb nqa yeeb nkab uas tuaj yeem siv hauv PPR cov kav dej, suav nrog:
1. Kev txhawb nqa ruaj khov: Cov no yog cov kev txhawb nqa nruj uas kho tag nrho txoj haujlwm ntawm cov yeeb nkab. Lawv feem ntau yog siv rau ntawm cov ntsiab lus thauj tog rau nkoj, kev hloov hauv kev taw qhia, thiab nyob ze cov khoom sib txuas. Cov kev txhawb nqa ruaj muaj xws li clamps, brackets, thiab hangers.
2. Kev txhawb nqa zawv zawg: Cov no yog cov kev txhawb nqa txav tau uas tso cai rau cov yeeb nkab kom nthuav dav thiab cog lus thermally yam tsis muaj kev ntxhov siab rau lub cev. Lawv feem ntau siv nyob rau hauv kev khiav dej num ntev ntawm cov kav dej kom haum rau kev txav los ntawm kev hloov kub. Kev txhawb nqa zawv zawg muaj xws li cov menyuam hangers thiab swb daim hlau.
3. Kev txhawb nqa tsis sib xws: Cov no yog cov kev txhawb nqa uas tuaj yeem kho lawv qhov siab lossis txoj haujlwm kom suav nrog kev hloov pauv ntawm cov khoom thauj lossis thermal expansion ntawm cov yeeb nkab. Lawv siv qhov twg cov yeeb nkab yuav raug hloov pauv hauv qhov siab lossis qhov chaw thauj khoom hloov lub sijhawm. Kev txhawb nqa sib txawv xws li lub caij nplooj ntoos hlav hangers thiab hydraulic txhawb nqa.
Kev txiav txim siab tsim
Thaum tsim cov yeeb nkab txhawb nqa rau PPR yeeb nkab tshuab, ntau yam yuav tsum tau txiav txim siab, suav nrog qhov siab tshaj plaws tso cai rau cov yeeb nkab kev ntxhov siab, txhawb kev sib nrug, thiab kev thauj khoom. Nws yog ib qho tseem ceeb los xyuas kom meej tias cov kev txhawb nqa tuaj yeem tiv taus cov kab ntsug thiab kab rov tav loads los ntawm cov kav dej thiab cov kua dej thauj. Qhov kev txhawb nqa yuav tsum tau txiav txim siab raws li cov yeeb nkab loj, qhov hnyav, thiab cov yam ntxwv thermal expansion. Tsis tas li ntawd, cov khoom xaiv rau kev txhawb nqa yuav tsum sib haum nrog PPR piping los tiv thaiv corrosion lossis tshuaj lom neeg.
Xaus
PPR yeeb nkab txhawb nqa yog cov khoom tseem ceeb ntawm cov kav dej tsim tau zoo. Kev tsim thiab kev txhawb nqa kom zoo yuav ua kom cov kav dej muaj kev tiv thaiv los ntawm kev puas tsuaj los ntawm kev ntxhov siab ntau dhau, kev co, lossis kev hloov kub. Los ntawm kev xaiv hom kev txhawb nqa uas tsim nyog thiab sib nrug ntawm lawv kom raug, PPR yeeb nkab tshuab tuaj yeem ua tiav qhov kev ua tau zoo thiab ua haujlwm ntev.
