ppr cov kav dej kub thiab txias S5, S4, S3.2, S2.5, S2 sawv cev rau tsib tus qauv, thiab cov kabmob siab ntawm txhua tus qauv sib txawv. ppr yog ib hom kav dej kub thiab txias, uas tau muab faib ua tsib series: S5, S4, S3.2, S2.5, thiab S2. Lub siab ntawm cov tsib series no yog 1.25MPA, 1.6MPA, 2MPA, 2.5MPA thiab 3.2MPA feem. , qhov loj dua tus nqi, qhov zoo dua lub siab bearing muaj peev xwm. Hauv kev tsim kho tam sim no, PPR cov kav dej tau pib siv dav, vim tias piv nrog cov kav hlau cam khwb cia lossis cov kav dej cement, PPR muaj zog ntau dua -txuag thiab tus phooj ywg ib puag ncig, thiab muaj kev tiv thaiv corrosion, uas ua rau muaj kev pabcuam ntau dua. lub neej. Tsis tas li ntawd, cov phab ntsa sab hauv ntawm PPR cov kav dej kub thiab dej txias Nws tsis yooj yim rau cov dej ntws tawm, thiab nws yooj yim heev los ntxuav thiab tswj, yog li nws nrov dua li cov kav dej ib txwm muaj.
Txawm li cas los xij, kuj tseem muaj qee qhov kev xav tau rau kev tsim thiab kev teeb tsa ntawm PPR cov kav dej kub. Nws yog tsim los ntawm PP-R kav dej thiab cov yeeb nkab fittings. Cov yeeb nkab fittings no yuav tsum ua kom tau raws li kev nyiam huv ntawm GB / T17219 tus qauv kom ua tiav tsib yam tshuaj lom. Thaum xaiv cov khoom, nws tus nqi pH yuav tsum tau tswj ntawm 1 thiab 14, thiab cov kua qaub thiab alkali yuav tsum tiv taus corrosion. Qhov thib ob, cov kav dej ntawm PPR cov kav dej kub thiab dej txias yuav tsum zoo ib yam thiab du, vim tias cov phab ntsa ntawm cov yeeb nkab tsis sib xws yuav ua rau cov dej ntws tsis zoo, yog li cov kav dej yuav sib sau rau ntawm phab ntsa ntawm cov yeeb nkab, thiab qhov smoother sab hauv. phab ntsa yog, qhov tsawg dua qhov kev vibration thiab suab nrov ntawm cov yeeb nkab dej yuav yog. Thaum kawg, kev teeb tsa ntawm PPR cov kav dej tsis tuaj yeem raug tawm sab nraud ntawm lub tsev, vim tias qhov kub ntawm cov phab ntsa sab hauv ntawm cov kav dej tsis sib xws, thiab qhov raug sab nraud tuaj yeem yooj yim ua rau cov kav dej tawg.
S yog lub cim ntawm lub raj series, qhov tsawg dua tus lej ua raws li S, qhov ntau dua phab ntsa thickness. Vim yog cov txiaj ntsig zoo no, cov kav dej PPR tau siv dav hauv cov tsev loj. Kev tsim cov kav dej zoo li no muab kev yooj yim zoo rau kev ua haujlwm ntawm cov kav dej hauv tsev, cov pa hauv nroog thiab kev thauj mus los ntawm cov kua dej.
