Kev kho dua tshiab hauv dej yog qhov tseem ceeb tshaj plaws ntawm kev kho kom zoo nkauj hauv tsev, ib yam li tib neeg cov hlab ntsha thiab ntshav, muab txoj sia rau lub tsev. PPR yeeb nkab tsis yog - lom, huv si, thiab muaj lub neej ua haujlwm ntev. Nws raug suav hais tias yog cov yeeb nkab ntsuab thiab txhim khu kev qha los ntawm kev tsim kho dej thiab kev lag luam dej. Vim nws qhov kev ua tau zoo - tus nqi siab, nws tau dhau los ua cov kav dej hauv tsev ntau tshaj plaws.
PPR Pipeline Qhov Zoo Gap Factors
PPR pipeline yog qhov tseeb cov khoom lag luam nrog cov thev naus laus zis ntau lawm. Los ntawm kev xav ntawm cov cuab yeej siv tshuab, tag nrho cov khoom tsim tau zoo ntawm cov tuam txhab lag luam niaj hnub no tsis txawv ntau. Cov laj thawj tseem ceeb uas ua rau muaj qhov tsis zoo yog cov hauv qab no:
1. Cov khoom siv ntau npaum li cas hauv cov khoom
2. Cov khoom siv purity
3. Kev ua haujlwm zoo
4. Lwm qhov chaw ntawm kev ua haujlwm ntxiv
Raws li cov neeg siv khoom, peb yuav tsum paub qhov txawv ntawm cov kav dej PPR zoo li cas? Qhov tseeb, nws tuaj yeem muab piv los ntawm cov lus qhia hauv qab no:
01 Phab ntsa thickness thiab kam rau ua
Cov kav dej Pas dej muaj ob qhov tshwj xeeb ntawm 20 thiab 25. Cov yeeb nkab phab ntsa tuab tsis sib xws hauv kev ua lag luam yog 202.8mm thiab 253.5mm, thiab qee qhov tseem tsawg dua qhov tuab no tom qab ntsuas. , lub neej thiab siab -kub kuj yuav tsis muaj zog. Poly pipes txawv ntawm lwm hom. Cov yeeb nkab specifications yog 203.4mm thiab 254.2mm, uas yog zoo dua li feem ntau hom tam sim no nyob rau hauv lub lag luam.
02 Zoo ntawm cov kav dej thiab fittings
Nyob rau hauv tib txoj kev, qhov hnyav ntawm cov kav dej ntawm tib lub specification, qhov zoo dua qhov compression kuj. Qhov no yog vim cov khoom siv yeeb nkab dej thiab cov yeeb nkab phab ntsa thickness ntawm txhua hom sib txawv. Nyob rau hauv qhov chaw ntawm tib qhov ntev, qhov hnyav dua cov yeeb nkab, qhov kev ntseeg tau zoo dua. Thaum xaiv cov kav dej PPR, koj tuaj yeem xav txiav ib feem ntawm cov kav dej ntawm tib qhov ntev thiab qhov tshwj xeeb rau kev hnyav thiab sib piv.
