Ua ib hom dej khoom siv tshiab, PPR yeeb nkab muaj kev zoo dua. Nws tuaj yeem siv ob qho tib si raws li cov yeeb nkab thiab raws li cov dej xa dej kub. Nws ua kab mob tsis zoo, hnyav, siab-resistant thiab corrosion-resistant. Hom khoom nce. Kuj tsim rau cov kav dej kub, cov kav dej ntshiab huv. Qhov nruab nrab ntawm lub PPR raj siv lub tshuab kub ntxhov, thiab lub raj muaj fused ua ke, yog li thaum lub qhov ntsuas qhov kev ntsuas siab dhau, tus PPR raj yuav tsis teev.
PP-R xa cov khoom fittings yog tsim los ntawm cov ntaub ntawv zoo, thiab kev ua tau zoo ntawm cov khoom ua tau raws lossis tshaj cov qauv thoob tebchaws GB / T18742. Nws kuj muaj cov nram qab no tshwj xeeb tsim thiab txheej txheem zoo:
● Kev siv txoj hlua khi loj rau txoj kev tsim muaj peev xwm ua rau txo cov yub dej hammer thiab tiv thaiv tub raj xo.
● 45 degree chamfer tsim ua vuam yooj yim dua.
