Taw qhia:
Pex (hla-txuas polyethylene) cov yeeb nkab fittings tau dav siv nyob rau hauv cov kav dej vim lawv qhov yooj yim, thiab tus nqi ua haujlwm zoo. Nkag siab ntawm phab ntsa qauv thiab lub zog ntawm PeX cov yeeb nkab fittings yog qhov tseem ceeb rau kev txhim khu kev txhim khu kev qha thiab muaj kev nyab xeeb plhaw. Kab lus no muab kev tshawb xyuas ntawm phab ntsa sib dhos thiab lub zog ntawm PeX cov yeeb nkab fittings, qhia qhov tseem ceeb uas ua rau lawv cov kev ua tau zoo thiab ntseeg tau.
1. Phab ntsa qauv ntawm PeX cov yeeb nkab fittings:
Lub phab ntsa qauv ntawm PeX cov yeeb nkab fitts plays lub luag haujlwm tseem ceeb hauv lawv lub zog tag nrho thiab lub zog. PeX fittings feem ntau muaj ob txheej: ib txheej sab nraud ua los ntawm cov polyethylene (HDPE) thiab sab hauv txheej txheem polyethylene (Pex). Tus HDPE txheej muab cov txheej txheem kev txhawb nqa thiab tiv thaiv cov kab peb los ntawm cov hluav taws xob sab nraud xws li UV hluav taws xob, tshuaj lom neeg, thiab kev puas tsuaj rau lub cev. Qhov no dual-txheej kev tsim kho kom muaj kev ncua ntev thiab muaj kev ruaj ntseg ntawm PeX cov yeeb nkab fittings.
2. Hla kev sib txuas cov txheej txheem thiab lub zog ua tiav:
Kev sib tw hla yog cov txheej txheem tseem ceeb hauv kev tsim cov PeX cov yeeb nkab fittings, vim nws ua rau lawv lub zog thiab kev hloov pauv thiab kub hloov pauv. Pex cov yeeb nkab fittings yog hla txuas siv ntau txoj hauv kev, suav nrog peroxide thiab electron nqaj irradiation. Cov txheej txheem no tsim cov kev sib txuas lus muaj zog ntawm cov ntaub pua av polymer, ua rau muaj cov khoom zoo dua qub. Hla-txuas PEX cov yeeb nkab fittings nthuav qhia zoo heev rau kev ntxhov siab, nkag, thiab deformation, kom ntseeg tau ntev ntev thiab kev ntseeg tau.
3. Qhov xwm txheej cuam tshuam rau lub zog:
Ntau yam cuam tshuam rau lub zog ntawm cov cox cov yeeb nkab fittings. Qhov zoo ntawm cov ntaub ntawv raw siv, qib kev hla kev sib txuas, thiab kev tsim khoom txhua txoj haujlwm ua si tseem ceeb. Cov kev sib txuas siab dua cov qauv hluav taws xob feem ntau ua rau muaj zog PeX fittings. Ib qho ntxiv, cov qauv tsim thiab cov duab ntawm cov fittings, xws li phab ntsa tuab thiab duab, kuj cuam tshuam lawv lub zog. Cov chaw tsim khoom ua raws cov qauv kev lag luam thiab yauv ua kom paub tseeb tias PeX tus yeeb nkab fittings ua raws li cov ntawv thov yuav tsum muaj zog rau cov khoom siv plumbing sib txawv.
4. Kuaj thiab ntawv pov thawj:
Txhawm rau kom muaj kev cia siab thiab kev nyab xeeb ntawm PeX cov yeeb nkab fittings, cov chaw tsim khoom kawm lawv cov txheej txheem kev ntsuas nruj thiab cov txheej txheem pov thawj. Ntau lub koom haum tseem ceeb hauv ntiaj teb, xws li ASTM International thiab ISO (cov txheej txheem thoob ntiaj teb rau kev ntsuas, ruaj khov, thiab kev ua haujlwm ntawm Pex fittings. Cov kev ntsuas no suav nrog kev sim tawg tawg, hydrostatic siab sim, thiab kev ntsuas ntev ntev. Los ntawm adhering rau cov qauv no thiab tau txais cov ntawv pov thawj, cov tuam txhab ua rau lawv cov kev cog lus los ua cov yeeb nkab cov yeeb nkab zoo.
5. Thov kev saib xyuas:
Thaum xaiv thiab txhim kho Pex cov yeeb nkab fittings, nws yog qhov tseem ceeb kom xav txog cov kev cai thov tshwj xeeb thiab ib puag ncig. Yam khoom xws li kub, siab, tshuaj lom neeg raug mob, thiab kev nyuaj siab yuav tsum tau soj ntsuam kom meej meej kom muaj cov fittings. Cov tswv yim tsim nyog, suav nrog txoj kev sib txuas ua ke tsim nyog, yog qhov tseem ceeb rau kev tswj hwm cov txheej txheem kev ncaj ncees thiab kev ua tau zoo ntawm cov kav dej ntawm PEX.
Xaus:
Lub phab ntsa qauv thiab lub zog ntawm PeX cov yeeb nkab fittings yog qhov tseem ceeb hauv kev txhim khu kev txhim khu kev qha thiab ruaj khov. Los ntawm cov txheej txheej dual, hla kev sib txuas ua cov txheej txheem, thiab kev tsim qauv ua rau cov neeg lag luam PEX, ua kom zoo tshaj plaws lub zog thiab kev tawm tsam rau ntau qhov chaw ib puag ncig. Los ntawm kev txiav txim siab cov cai yuav tsum tau ua thiab ua raws li cov kev coj ua kom zoo, cov neeg siv tuaj yeem ua kom zoo tshaj plaws thiab kev ua haujlwm ntev ntawm Pex Plhuab cov tshuab.
