PEX Yeeb Nkab Qhia:
Khoom siv:
PEX (cross-linked polyethylene) yog ib hom yas uas paub txog nws cov kav ntev, yoog raws, thiab tiv thaiv corrosion. Nws yog tsim los ntawm cov txheej txheem uas cuam tshuam nrog kev sib txuas ntawm polyethylene molecules, uas txhim kho nws lub zog thiab kev ua haujlwm.
Hom PEX Pipes:
Muaj peb yam tseem ceeb ntawm cov kav dej PEX: PEX-A, PEX-B, thiab PEX-C, txhua tus muaj nws tus kheej txoj kev tsim khoom thiab cov yam ntxwv. PEX-A paub txog nws qhov kev hloov pauv zoo tshaj plaws, PEX-B yog tus nqi tsim nyog thiab yooj yim rau kev ua haujlwm nrog, thaum PEX-C muaj qhov sib npaug ntawm qhov yooj yim thiab pheej yig.
Keeb kwm:
PEX piping yog thawj zaug hauv xyoo 1960 uas yog lwm txoj hauv kev rau cov khoom siv xws li tooj liab thiab PVC rau cov kav dej thiab cua sov. Nws pib siv yog nyob rau hauv radiant pem teb cua sov tshuab, qhov twg nws yooj yim thiab yooj yim ntawm installation yog tshwj xeeb tshaj yog zoo. Tau ntau xyoo, PEX tau txais kev lees paub thoob plaws hauv kev tsim kho kev lag luam vim nws cov txiaj ntsig ntau.
Qauv:
PEX cov kav dej yog tsim los ua kom tau raws li ntau yam kev lag luam qauv los xyuas kom meej qhov zoo thiab kev ua tau zoo sib xws. Cov qauv siv rau PEX piping suav nrog ASTM F876 rau PEX tubing siv hauv cov kav dej thiab ASTM F877 rau PEX tubing npaj rau cov cua kub cua sov. Kev ua raws li cov qauv no pab tau lees tias cov kav dej PEX ua tau raws li cov kev cai tshwj xeeb hais txog yam xws li kev ntsuas siab, kub tsis kam, thiab tshuaj lom neeg sib xyaw.
Daim ntawv thov:
PEX piping yog siv dav hauv kev tsim kho vaj tse thiab kev lag luam rau ntau yam kev siv, suav nrog:
Cov kav dej: PEX cov kav dej feem ntau yog siv rau kev faib dej hauv cov tsev vim lawv tsis kam tiv thaiv corrosion thiab scale buildup.
Radiant cua sov tshuab: PEX tubing yog qhov kev xaiv nrov rau cov cua sov hauv pem teb vim nws qhov yooj yim thiab thermal efficiency.
Snow melting systems: PEX cov kav dej kuj tseem siv tau rau hauv cov txheej txheem daus daus kom cov kev tsav tsheb thiab cov kev taug kev kom tsis txhob muaj daus thiab dej khov.
HVAC systems: PEX piping yog tsim rau hydronic cua sov thiab cua txias tshuab, muab kev ua tau zoo thiab kav ntev.
Qhov zoo ntawm PEX Yeeb Nkab:
Flexibility:
PEX yeeb nkab yog hloov tau yooj yim, tso cai rau kev yooj yim installation nyob ib ncig ntawm cov ces kaum thiab obstacles yam tsis tas yuav tsum tau ntxiv fittings. Qhov kev hloov pauv no txo qhov kev pheej hmoo ntawm kev xau thiab ua kom yooj yim rau cov txheej txheem kav dej.
Corrosion Resistance:
Tsis zoo li cov kav hlau xws li tooj liab, PEX yeeb nkab tiv taus corrosion, scaling, thiab pitting. Cov cuab yeej no ua rau lub neej ntev ntawm cov kav dej thiab ua kom cov dej zoo nyob hauv siab.
Thermal Expansion:
PEX yeeb nkab tuaj yeem nthuav dav thiab cog lus nrog qhov kub thiab txias, txo qhov kev pheej hmoo ntawm cov kav dej tawg hauv qhov txias txias. Qhov kev nthuav dav thermal no ua rau PEX zoo tagnrho rau kev siv huab cua txias.
