Cov ntsiab lus PEX yeeb nkab thiab PEX raj tau siv sib hloov, txawm li cas los xij qee cov tuam txhab lag luam paub qhov txawv ntawm ob los ntawm kev tsim khoom mus rau qhov sib txawv sab hauv / sab nraud. Piv txwv li, PEX yeeb nkab yuav raug tsim los rau IPS-ID (hlau yeeb nkab loj, nyob rau hauv txoj kab uas hla tswj) qhov ntau thiab tsawg nrog cov thickness sib txawv kom tau raws li qhov yuav tsum tau muaj siab, thaum PEX raj yuav raug tsim rau CTS-OD (tooj liab tubing loj, sab nraud txoj kab uas hla tswj) qhov ntau thiab tsawg. , feem ntau nrog tus qauv thickness ntawm SDR-9 (tus qauv dimension piv).
PEX raj tsim rau CTS-OD qhov ntau thiab tsawg yog qhov ntau, nrog rau qhov ntau thiab tsawg suav nrog 3/8", 1/2", 5/8", 3/4&] quot; thiab 1". Hauv lub vev xaib no,"PEX tube" hais txog cov khoom siv CTS-OD no.
Ua ntej extrusion, HDPE tuaj yeem ua xim los tsim cov kav dej muaj xim. Hom PEX yeeb nkab xim yog" ntuj" (dawb thiab ntshiab, tsis muaj xim), dawb, dub, liab thiab xiav. Liab thiab xiav yog siv los pab cov kav dej thiab cov tswv tsev paub qhov txawv ntawm cov kav dej kub thiab dej txias. Yuav muaj cov cim rau sab nraud ntawm cov yeeb nkab kom pom cov qauv twg nws ua tau.
Thaum lub sij hawm tsim khoom, PEX raug mob ntawm reels rau kev khaws cia thiab kev thauj mus los. Ib qho 1/2-nti PEX ncej tuaj yeem tuav 1,200 ko taw ntawm tubing.
