Rau ob qho tib si hauv tsev thiab kev lag luam cov kav dej, xaiv cov khoom siv yeeb nkab zoo yog qhov tseem ceeb rau kev ntsuas tus nqi, kev ua tau zoo, thiab kev ua haujlwm ntev. Ob qhov kev xaiv nrov yog crosslinked polyethylene (PEX) cov kav dej yas thiab cov kav hlau ib txwm siv. Raws li ib tug qub tub rog cov kav dej thiab cov neeg cog lus, Kuv tau teeb tsa mais ntawm PEX thiab cov kav dej steel. Hauv phau ntawv qhia no, Kuv mam li muab piv rau PEX thiab cov yeeb nkab steel thoob plaws yam xws li kev ua haujlwm ntev, kev tiv thaiv corrosion, kev teeb tsa kev sib tw, khov tsis kam, thiab tus nqi mus sij hawm ntev. Kuv lub hom phiaj yog los muab cov kws tshaj lij kev xav tsis txaus ntseeg los pab txiav txim siab seb cov khoom siv twg yuav haum rau koj cov kev xav tau tshwj xeeb ntawm cov kav dej.
PEX Pipe Txheej txheem cej luam
Ua ntej, keeb kwm nrawm ntawm PEX tubing. PEX stands rau cross-linked polyethylene, ib tug tshwj xeeb yas piping feem ntau siv rau cov dej kub thiab txias potable xa nrog rau radiant pem teb cua sov systems. Cov yam ntxwv tseem ceeb muaj xws li:
- Yooj yim rau cov tubing yas tsis siv cov kav dej khov. Withstands khov thiab tiv taus corrosion.
- Yooj yim thawb-haum, compression lossis crimp kev sib txuas. Tsis xav tau gluing lossis torching.
- Yooj yim rau DIY cov tswv tsev rau nruab. Nws tuaj yeem khoov ntawm cov ces kaum, txo cov pob qij txha.
- Ntau hom yog PEX-A, PEX-B, thiab PEX-C nrog qhov sib txawv ntawm qhov kub thiab txias.
- Qhov ntau thiab tsawg ntawm 1/4 "mus rau 2" rau cov ntawv thov nyob. 1/2 "rau 1" yog feem ntau.
- Cia siab tias yuav muaj 50 xyoo ntxiv nrog rau kev teeb tsa kom raug. Kev tu-dawb.
Nrog nws cov kav dej hloov tau yooj yim, kev sib koom ua ke yooj yim, thiab kev tiv thaiv corrosion, PEX tau txais koob meej raws li lwm txoj hauv kev rau cov kav hlau. Tab sis li cas nws tiag tiag piv rau hlau?
Steel Pipe Txheej txheem cej luam
Hlau tau siv rau ntau xyoo hauv kev lag luam thiab cov kav dej hauv tsev. Nws cov yam ntxwv muaj xws li:
- Rigid hlau kav. Ntau cov phab ntsa thicknesses los ntawm lub teeb 1/2 "mus rau hnyav 1" ntxiv rau qhov ntau thiab tsawg coj mus muag.
-Teflon fittings yuav tsum tau threaded, Teflon daim kab xev, thiab wrenched nruj. Labor-intensive pob qij txha.
- Cov khoom siv muaj zog nrog kev ntsuas siab zoo. Nrog kev tsim txom.
- Corrosion muaj peev xwm ua rau xau, txawm tias galvanized thiab stainless hlau tiv thaiv corrosion.
- Qhov ntau thiab tsawg ntawm 1/4 "mus rau ntau ntiv tes.
- Muaj peev xwm kav ntev dua 70 xyoo hauv cov xwm txheej zoo. Outlasts cov tsev.
Nrog nws lub zog tab sis xav tau kev sib txuas, cov hlau tseem nrov hauv kev lag luam kav dej, tab sis cov tswv tsev yuav tsum ntsuas qhov kev sib pauv pauv piv rau PEX yooj yim dua.
Tus nqi sib piv: PEX vs Steel
Ib qho tseem ceeb hauv kev xaiv cov yeeb nkab yog tus nqi, ntawm ob qho tib si cov ntaub ntawv thiab kev ua haujlwm:
PEX:
- Pheej yig polyethylene tubing, feem ntau qis dua $ 1 ib ko taw.
- Tus nqi qis fittings zoo li crimp rings rau kev sib txuas. Ua tiav cov pob qij txha tuaj yeem qis dua $ 5.
- Tsis tas yuav muaj cov cuab yeej tshwj xeeb. Nruab nrog yooj yim crimper, cutter, thiab expander.
- Yooj yim rau nruab. Yooj yim txiav thiab nrawm nrawm.
- DIY-phooj ywg installation ntxiv txo cov nqi zog.
Hlau:
- Tsawg carbon steel kav ib leeg yog $1-$5 ib ko taw, raws li txoj kab uas hla thiab hlau ua lag luam.
- Fittings, txiv mis, thiab couplings ntxiv rau cov nqi khoom.
- Kev sib koom ua ke, Teflon daim kab xev, thiab wrenches xav tau rau kev teeb tsa.
- Yooj yim rau xov, de-burr, huv, thiab sib dhos threaded pob qij txha.
- Kev txhim kho yuav tsum muaj kev lag luam paub txog kev sib txuas thiab kev sib koom ua ke steel yeeb nkab.
Zuag qhia tag nrho, PEX piping systems tuaj yeem raug nqi 50 feem pua lossis tsawg dua li cov hlau sib piv. Tab sis rau qhov loj dua txoj kab uas hla tsis tshua muaj siab ua lag luam qhov twg steel nqi ib ko taw poob, cov khoom siv nqi sib txawv nqaim. Txawm li cas los xij, PEX khaws cov kev txuag nyiaj ua haujlwm tseem ceeb. Thaum cov hlau hnyav yog qhov zoo tagnrho rau qee qhov kev siv, PEX tsim nyog rau kev txiav txim siab rau nws tus nqi pheej yig.
Kev sib piv: PEX vs Steel
Tshaj li cov nqi raw, cov khoom ua tau zoo kuj cuam tshuam rau kev xaiv cov khoom:
PEX:
- Saj zawg zog tubing simplifies routing los ntawm framing thiab joists vs steel.
- Tsis muaj hluav taws kub. Steel threading thiab jointer compound muaj qhov qhib nplaim taws.
- Tau yooj yim yuav retrofitted rau hauv cov kav dej uas twb muaj lawm.
- Cov dej ntws qis dua li cov hlau tsis muaj zog. Minimizes suab tsis txaus siab.
- Qhov ntsuas kub siab tshaj 200 ° F. Haum rau kev xa dej kub.
- Muaj peev xwm tiv taus siab txog 200psi @ 73 degree F. Siab tawg siab dua thaum kub.
Hlau:
- Rigid yeeb nkab nrog threaded fittings xav tau kev npaj rau lem thiab routing.
- Cov ntaub ntawv pov thawj thaum raug kaw thiab txhawb nqa.
- Withstands tshaj 300 degree F. Siv rau chav kab thiab cua sov.
- Kev ntsuas siab siab tshaj 300psi rau lub sijhawm 40 steel.
- Thick steel deadens suab thiab txo cov dej rauj vibrations.
PEX muab kev yooj yim dua thiab kev teeb tsa rau DIYers, thaum cov hlau haum rau cov ntawv thov kev lag luam siab / siab. Yuav tsum tau txiav txim siab qhov ua tau zoo tshaj plaws.
Installation Sib piv: PEX vs Steel
Yooj yim thiab ceev ntawm kev teeb tsa kuj cuam tshuam cov khoom ntsuas:
PEX:
- Tsis muaj kev txawj tshwj xeeb lossis cov cuab yeej xav tau. Txiav tubing thiab txuas fittings.
- Yooj yim installation nrog yooj yim thawb-haum lossis crimp kev sib txuas.
- Flexibility tso cai rau routing los ntawm framing nrog tsawg txiav.
- Kev sib txuas tsawg dua li cov hlau vim yog khoov ntawm cov ces kaum.
- Nthuav cov cuab yeej tsim kev ruaj ntseg, txhim khu kev qha pob qij txha. Tsis xav tau threading.
Hlau:
- Piping txuj ci tsim nyog rau kev txiav, deburring, threading, thiab sib dhos.
- Yooj yim, kev npaj yuav tsum tau ua ua ntej sib dhos threaded pob qij txha.
- Hlau yuav tsum tau annealed nrog torches rau khoov. Cov kav dej txwv tsis pub nyob nruj.
- Kev sib txuas ntawm threaded yuav tsum ncaj ncaj thiab ua kom zoo kom tsis txhob xau.
- Kev sib koom ua ke thiab Teflon daim kab xev foob xov, tab sis ua kom muaj kev ntxhov siab yuav tsum tau ntxuav.
Rau cov novice DIYers lossis ib tus neeg muaj txiaj ntsig kev teeb tsa yooj yim, PEX muab qhov kev kawm qis dua. Flexible tubing thiab thawb-fittings ua kom muaj kev sib txuas nrawm yam tsis muaj qhov sib txuas lossis cov khoom siv threading. PEX teeb tsa hauv ib feem ntawm lub sijhawm.
Txawm li cas los xij, kev tsim cov khoom siv hlau tau tso cai rau cov kav dej ua lag luam muaj zog heev. Kev sib tsoo-pov thawj threaded kev sib txuas tuaj yeem ua rau ntau tiam neeg yog tias ua tau zoo. Qhov kub thiab txias siab tsis muaj kev txhawj xeeb. Qhov kev cia siab no ua rau cov hlau zoo tagnrho rau kev lag luam hnyav.
Kev sib piv kev saib xyuas: PEX vs Steel
Kev saib xyuas tsis tu ncua sib txawv ntawm cov khoom siv:
PEX:
- Tsis xav tau kev saib xyuas. Tsis corrode los yog scale buildup nyob rau lub sij hawm.
- Cov dej xau yuav tsum tau kho tsis zoo. Nws kav 50 xyoo ntxiv yam tsis muaj teeb meem.
- Flexible tubing yog khov-resistant. Withstands khov-thaw cycles.
Hlau:
- Corrosion muaj peev xwm ua rau qhov kawg pinhole to, nyob ntawm cov dej chemistry. Galvanized thiab stainless hlau tiv thaiv corrosion zoo dua li cov pa roj carbon steel thiab cam khwb cia hlau kav yog tias ntsia tau zoo.
- Periodic repainting ntawm faus steel kab xav tau los tiv thaiv corrosion.
- Muaj peev xwm kav ntev heev - tshaj 70 xyoo kev pab cuam lub neej.
- Cov kav dej txhav tawg yog tias dej khov. Rwb thaiv tsev thiab cua sov tracing yog xav tau nyob rau hauv cov huab cua txias.
Yog tias tau teeb tsa kom raug siv cov lus qhia chaw tsim khoom, PEX yuav tsum tsis muaj kev saib xyuas txuas ntxiv tshwj tsis yog kev hloov kho / valve hloov ntau xyoo dhau los. Cov hlau yuav tsum tau xaiv, ntsia, thiab tswj raws li cov qauv kom ua kom muaj kev tiv thaiv corrosion raws li ib puag ncig xws li av pH, dej pH, thiab kub. Tab sis cov hlau tuav kom zoo tuaj yeem ua haujlwm tau zoo rau lub neej.
Kev siv zoo tshaj plaws: PEX vs Steel
Raws li cov xwm txheej saum toj no, cov kev siv zoo tshaj plaws ua raws li:
