Kev cuam tshuam cov hmoov txhuas hauv UK cov dej haus tseem yog ib qho kev txhawj xeeb, raws li kev sim tsis ntev los no pom 14 ntawm 81 lub tsev kawm ntawv uas muaj cov hlau lead ntau dua 50 µg / L - tsib npaug ntawm qhov siab tshaj plaws tau pom zoo. UKCA-certified, tsis muaj txhuastooj dag tee fittingspab tiv thaiv cov kev pheej hmoo zoo li no, txhawb kev noj qab haus huv rau pej xeem thiab cov qauv kev cai nruj rau kev nyab xeeb ntawm cov dej.
Ntsiab Cai
- Lead-free UKCA-certified brass tee fittings tiv thaiv kev phom sij ntawm cov hmoov txhuas hauv cov dej haus, tiv thaiv kev noj qab haus huv tshwj xeeb rau cov menyuam yaus thiab cov poj niam cev xeeb tub.
- Brass tee fittings xyuas kom muaj zog, kev sib txuas ntawm cov kav dej hauv cov kav dej, thiab cov qauv tsis muaj hlau lead muaj cov kav ntev, kev nyab xeeb, thiab cov txiaj ntsig ib puag ncig.
- UKCA daim ntawv pov thawj lav fittings ua tau raws li UK nruj kev nyab xeeb thiab cov qauv zoo, pab cov tuam ntxhab thiab cov kav dej ua raws li cov cai thiab txhawb nqa dej nyab xeeb.
Vim li cas Lead-Free, UKCA-Certified Brass Tee Fittings Matter
Kev noj qab haus huv txaus ntshai ntawm cov hmoov txhuas hauv cov dej haus
Kev kis kab mob txhuas hauv cov dej haus ua rau muaj kev hem thawj rau kev noj qab haus huv, tshwj xeeb tshaj yog rau cov neeg tsis muaj zog xws li menyuam yaus thiab cov poj niam cev xeeb tub. Cov kev tshawb fawb tshawb fawb tau pom tias txawm tias cov hlau lead raug qis tuaj yeem ua rau muaj kev phom sij loj.
- Cov menyuam yaus uas raug coj mus rau tej zaum yuav ntsib kev puas hlwb thiab kev txawj ntse, suav nrog kev txo qis IQ, kev tsis txaus siab, kev kawm tsis taus, thiab teeb meem kev coj cwj pwm.
- Cov neeg laus ntsib kev pheej hmoo siab ntawm kev kub siab, lub raum puas, kab mob plawv, thiab cov teeb meem kev loj hlob.
- Cov poj niam cev xeeb tub uas raug cov dej tsis muaj hmoov txhuas muaj feem ntau dua ntawm kev nchuav menyuam, yug ntxov ntxov, thiab kev loj hlob ntawm lawv cov menyuam.
- Kev raug mob ntev, txawm tias qhov qis qis, tuaj yeem ua rau muaj kev noj qab haus huv mus ntev rau txhua pawg hnub nyoog.
Lub Koom Haum Saib Xyuas Kev Noj Qab Haus Huv (World Health Organization) thiab US Environmental Protection Agency tau teeb tsa cov qib siab tshaj plaws uas tso cai rau cov hmoov lead hauv cov dej haus (0.01 mg / L thiab 0.015 mg / L, ntsig txog) vim cov kev pheej hmoo no. Cov kev tshawb fawb, xws li ib qho ua nyob rau hauv Hamburg, lub teb chaws Yelemees, pom muaj kev sib raug zoo ntawm cov hlau lead hauv cov dej kais dej thiab cov ntshav lead hauv cov ntshav siab. Cov kev cuam tshuam zoo li dej ntws los yog hloov mus rau cov dej hauv lub raj mis ua rau txo qis cov hmoov lead hauv cov ntshav. Cov kev tshawb pom no qhia txog qhov tseem ceeb ntawm kev tshem tawm cov khoom siv lead ua hauv dej los tiv thaiv pej xeem kev noj qab haus huv.
Qhov tseem ceeb ntawm Brass Tee Fittings hauv Dej Systems
Brass Tee Fittings ua lub luag haujlwm tseem ceeb hauv ob qho tib si hauv tsev thiab kev lag luam xa dej.
- Brass, alloy ntawm tooj liab thiab zinc, muaj kev tiv thaiv zoo corrosion thiab malleability, ua rau nws zoo tagnrho rau kev siv kav dej.
- Cov fittings no ruaj ntseg txuas cov kav dej, tso cai rau kev hloov pauv ntawm cov khoom sib txawv ntawm cov yeeb nkab thiab ua rau cov kav dej sib txawv.
- Brass tee fittings tswj cov dej ntws, tswj kev ncaj ncees nyob rau hauv kev kub siab thiab kub, thiab muab cov ntsaws ruaj ruaj, xau-pov thawj.
- Lawv durability thiab corrosion kuj ua rau lub neej ntev ntawm cov kav dej, txo kev tu thiab hloov cov kev xav tau.
- Lub union tee variant tso cai rau yooj yim disassembly thiab reassembly, yooj yim txij nkawm yam tsis cuam tshuam rau tag nrho cov system.
- Brass tee fittings kuj tseem siv tau, txhawb kev ruaj ntseg ib puag ncig.
Los ntawm kev ua kom ntseeg tau kev sib txuas thiab kev ua haujlwm ntawm lub cev, cov fittings no pab tiv thaiv kom tsis txhob muaj kab mob thiab kis kab mob, uas yog qhov tseem ceeb rau kev tswj xyuas dej kom zoo thiab kev nyab xeeb.
Cov txiaj ntsig ntawm Lead-Free Brass Tee Fittings
Lead-free tooj dag tee fittings muaj ntau qhov zoo dua li cov tsoos tooj dag fittings uas yuav muaj txhuas.
- Kev nyab xeeb: Cov fittings no tshem tawm txoj kev pheej hmoo ntawm cov hlau lead lom los ntawm kev tiv thaiv cov hmoov lead lom los ntawm cov dej haus, yog li tiv thaiv tib neeg kev noj qab haus huv.
- Durability: Cov hlau tsis muaj hlau lead ua kom muaj kev tiv thaiv corrosion thiab yaig, ua kom muaj kev ua haujlwm ntev ntev hauv kev xav tau dej hauv ib puag ncig.
- Environmental Friendliness: Los ntawm kev zam kom tsis txhob muaj kev phom sij cuam tshuam nrog cov hlau lead, cov fittings no txo cov kev cuam tshuam ib puag ncig thiab txhawb cov hom phiaj kev ruaj ntseg.
- Kev Tswj Xyuas Kev Ua Raws Cai: Cov hlau lead-dawb tooj dag tee fittings ua tau raws li kev cai lij choj, xws li Txoj Cai Txo Cov Lead hauv Dej Haus, uas txwv cov ntsiab lus tsis pub ntau tshaj 0.25% los ntawm qhov hnyav hauv qhov chaw ntub dej. Qhov kev ua raws cai no yog qhov tseem ceeb rau kev tsim kho tshiab thiab kho dua tshiab.
- Cov txiaj ntsig kev noj qab haus huv zoo dua: Kev txo qis cov hmoov lead hauv cov kab dej txhawb nqa tag nrho cov zej zog kev noj qab haus huv thiab kev nyab xeeb.
Cov kev tshawb fawb tsis ntev los no qhia tau hais tias txawm tias fittings ua lag luam raws li tsis muaj txhuas tuaj yeem tso tawm me me ntawm cov hlau lead, tshwj xeeb tshaj yog tom qab kev teeb tsa xws li txiav lossis polishing. Txawm li cas los xij, UKCA-certified, tsis muaj hlau lead-dawb tooj dag tee fittings raug kuaj nruj thiab tswj kom zoo, txo qhov kev pheej hmoo no thiab ua kom cov qauv siab tshaj plaws ntawm kev nyab xeeb dej. Cov khoom muaj ntawv pov thawj no tseem muaj kev ua tau zoo dua qub thiab kev lees paub ntev dua piv rau lwm qhov tsis muaj ntawv pov thawj, muab kev thaj yeeb nyab xeeb rau ob qho tib si installers thiab cov neeg siv kawg.
Kev ua raws cai, ntawv pov thawj, thiab kev hloov pauv rau Brass Tee Fittings
Nkag siab txog UKCA Certification thiab Nws Qhov Tseem Ceeb

Cov Kev Cai thiab Cov Qauv Tseem Ceeb (UKCA, NSF/ANSI/CAN 372, BSEN1254-1, EU/UK Cov Lus Qhia)
Ntau cov kev cai thiab cov qauv ua kom muaj kev nyab xeeb thiab zoo ntawm cov dej haus fittings. Txoj Cai 4 ntawm Kev Siv Dej (Dej Fittings) Txoj Cai 1999 yuav tsum muaj cov fittings los tiv thaiv kev sib kis thiab siv tsis raug. Cov khoom yuav tsum tsis txhob tso cov tshuaj phem thiab yuav tsum ua raws li British Standards los yog pom zoo specifications. Cov ntaub ntawv pov thawj zoo li WRAS, KIWA, thiab NSF kuaj thiab muab ntawv pov thawj cov khoom, muab kev lees paub tias Brass Tee Fittings tswj dej zoo. Cov qauv xws li NSF / ANSI / CAN 372 thiab BSEN1254-1 tau teeb tsa cov kev txwv nruj rau cov ntsiab lus txhuas thiab kev ua haujlwm txhua yam.
Daim ntawv pov thawj, Kev Ntsuas, thiab Kev Tswj Xyuas Zoo (nrog rau XRF Kev Ntsuam Xyuas)
Cov neeg tsim khoom siv cov txheej txheem ntsuas qib siab los txheeb xyuas cov ntsiab lus txhuas hauv Brass Tee Fittings. Kev tsom xam X-ray fluorescence (XRF) yog cov txheej txheem tseem ceeb uas tsis muaj kev puas tsuaj. Nws muab cov txiaj ntsig sai, raug rau cov ntsiab lus muaj pes tsawg leeg, suav nrog qib txhuas. Handheld XRF analyzers tso cai rau kev txheeb xyuas ntawm qhov chaw thaum lub sijhawm tsim khoom, txhawb kev ruaj ntseg zoo. Lwm txoj hauv kev suav nrog kev tshuaj xyuas qhov muag rau qhov chaw tsis xws luag thiab kev sim tshuab rau lub zog. Tshuaj ntsuam xyuas, xws li ntub chemistry, muab cov ncauj lus kom ntxaws txog kev puas tsuaj. Cov txheej txheem no ua kom cov fittings ua tau raws li cov qauv kev cai thiab tsis ua rau muaj kev phom sij rau kev noj qab haus huv.
Hloov Cov Kev Sib Tw thiab Kev daws teeb meem rau cov neeg tsim khoom thiab cov kav dej
Cov neeg tsim khoom ntsib ntau qhov teeb meem thaum hloov mus rau tsis muaj txhuas, UKCA-certified Brass Tee Fittings:
