Qhov txawv ntawm PEX thiab PERT yeeb nkab yog dab tsi?
Thaum nws los txog rau cov kav dej niaj hnub no, PEX thiab PERT kav dej tau dhau los ua ob hom kav dej uas siv ntau tshaj plaws. Ob lub kav dej hloov tau yooj yim thiab yooj yim rau nruab, tab sis lawv muaj qee qhov sib txawv tseem ceeb uas cuam tshuam rau lawv cov ntawv thov, kav ntev, thiab tag nrho cov nqi.
PEX Pipe yog dab tsi?
PEX, lub npe hu ua cross-linked polyethylene, yog ib hom yas tubing uas feem ntau siv rau cov kav dej kub thiab dej txias. PEX tubing yog hloov tau nrog ib tug du thiab nruam sab hauv nto, ua rau nws yooj yim rau nruab thiab ua hauj lwm nrog.
PEX muaj nyob rau hauv ntau qhov ntau thiab tsawg, nrog rau feem ntau yog 1/2 nti, 3/4 nti, thiab 1 nti. PEX piping yog xim-coded, nrog liab tubing feem ntau siv rau cov dej kub thiab xiav tubing rau dej txias.
PEX tubing tuaj yeem koom nrog ntau yam kev sib txuas, suav nrog crimp, clamp, thawb-haum, thiab compression fittings, ua kom yooj yim rau kev siv ntau yam kev siv.PEX tubing yog qhov ruaj khov thiab tuaj yeem kav ntev txog 50 xyoo.
PERT Pipe yog dab tsi?
PERT, lub npe hu ua polyethylene tsa kub, yog lwm hom yas tubing uas yog siv rau cov kav dej. PERT tubing kuj hloov tau nrog lub ntsej muag sab hauv, tab sis nws muaj kev tiv thaiv ntau dua rau cua sov.
PERT tubing tuaj nyob rau hauv ntau qhov ntau thiab tsawg, suav nrog 1/2 nti, 3/4 nti, thiab 1 nti, thiab yog xim-coded, nrog liab tubing siv rau dej kub thiab xiav tubing siv rau cov dej txias.
PERT tubing tuaj yeem koom nrog hauv pob tw-fusion, electrofusion, lossis compression fittings, ua kom muaj ntau yam hauv cov kav dej.PERT tubing tseem muaj zog heev thiab tuaj yeem kav ntev txog 50 xyoo.
Qhov txawv ntawm PEX thiab PERT yeeb nkab yog dab tsi?
Thaum PEX thiab PERT cov kav dej muaj ntau qhov sib xws, muaj qee qhov sib txawv tseem ceeb uas muab lawv sib nrug:
1. Kub Resistance:
Ib qho ntawm qhov sib txawv tseem ceeb ntawm PEX thiab PERT kav yog lawv qhov kub thiab txias. Thaum PEX tuaj yeem tiv taus qhov kub txog li 200 degree F (93 degree), PERT muaj kev tiv thaiv ntau dua rau cov cua sov thiab tuaj yeem tiv taus kub txog 180 degree F (82 degree).
Qhov no ua rau PEX tsim nyog rau cov ntawv thov uas muaj qhov kub thiab txias, xws li hauv cov tshuab cua sov. Ntawm qhov tod tes, PERT yog qhov tsim nyog rau cov ntawv thov uas qhov kub tsis siab dhau, xws li hauv cov kav dej txias.
2. Kev ntsuas siab:
Lwm qhov sib txawv tseem ceeb ntawm PEX thiab PERT kav yog lawv qhov kev ntsuas siab. PEX cov kav dej muaj qhov ntsuas siab dua piv rau PERT kav dej.
PEX piping tuaj yeem tuav txog 80 psi ntawm 200 degree F (93 degree), thaum PERT piping tuaj yeem tuav txog 45 psi ntawm 180 degree F (82 degree). Qhov no ua rau PEX tsim nyog rau cov ntawv thov siab, xws li hauv cov dej kub cua sov.
3. Tus nqi:
PEX thiab PERT kav kuj txawv ntawm lawv cov nqi. PEX tubing feem ntau kim dua PERT tubing.
Qhov sib txawv ntawm tus nqi yog vim cov txheej txheem tsim khoom siv los tsim cov kav dej no. PEX tubing yog tsim los siv cov txheej txheem sib txuas, uas cuam tshuam nrog kev kho cov polymer nrog tshuaj lom neeg lossis hluav taws xob los tsim kom muaj zog molecular bond. PERT, ntawm qhov tod tes, yog tsim los siv ib txheej txheej extrusion, uas yooj yim dua thiab tsis tshua kim.
4. Yooj yim ntawm installation:
Ob leeg PEX thiab PERT kav yog ib qho yooj yim rau nruab, tab sis PEX tubing muaj qhov zoo dua thaum nws los txog rau kev yooj yim ntawm kev teeb tsa.
PEX piping yog qhov hloov tau yooj yim, ua kom yooj yim rau kev ua haujlwm nyob ib ncig ntawm qhov chaw nruj thiab cov ces kaum. Nws tseem tuaj yeem khoov yam tsis tas yuav tsum tau fittings. PERT tubing tsis tshua muaj kev hloov pauv thiab yuav tsum muaj kev sib txuas ntau dua los mus ncig ntawm qhov chaw nruj lossis tig.
Xaus
PEX thiab PERT kav yog ob hom yas tubing feem ntau siv hauv cov kav dej. Thaum lawv muaj ntau qhov sib xws xws li kev yooj yim thiab yooj yim ntawm kev teeb tsa, lawv sib txawv ntawm qhov kub thiab txias, kev ntsuas siab, tus nqi, thiab kev yooj yim ntawm kev teeb tsa.
PEX piping yog qhov tsim nyog rau cov dej kub thiab cov ntawv siv siab, thaum PERT tubing yog qhov tsim nyog rau cov dej txias thiab cov ntawv siv nrog qhov kub thiab txias. Kev xaiv ntawm ob lub kav dej no kawg yog nyob ntawm qhov xav tau tshwj xeeb ntawm cov kav dej thiab cov peev nyiaj.
