UNS C12200yog ib lub lag luam ntshiab tooj liab uas yog phosphorus deoxidized, nrog siab residual phosphorus. Nws tseem hu ua DHP tooj liab. Nws yog dav siv rau kev tsim cov seamless tooj liab dej raj raws li ASTM B88. GNEE's UNS C12200 seamless tooj liab raj yog tsim los rau cov kav dej dav dav thiab kev xa tawm ntawm lwm cov kua dej zoo sib xws.
Tube Hom Raws li Phab Ntsa Thickness
| Hom | Phab ntsa Thickness | Daim ntawv thov |
|---|---|---|
| Hom K | Thickest | Cov dej hauv av hauv av, siab -siab tshuab |
| Hom L | Nruab nrab | Chaw nyob thiab kev lag luam dej kub / dej txias |
| Hom M | thinnest | Tsawg-cov ntawv thov nyob hauv siab |
Kev xaiv hom raj yog txiav txim siab los ntawm cov kua dej sab hauv lossis sab nraud, kev teeb tsa thiab kev pabcuam, thiab cov kev cai hauv zos. Kev sib koom ua ke (soldering, flaring, lossis compression) los yog dabtsi yog khoov kuj tseem cuam tshuam rau kev xaiv.
Qhov zoo ntawm Copper C12200 Tubes rau Cov kav dej
1. Antimicrobial & Antifungal
Tooj liab muaj cov tshuaj tua kab mob ntuj tsim vim tooj liab ions cuam tshuam cov cell membranes thiab DNA ntawm cov kab mob, fungi, thiab lwm yam kab mob, tua lawv zoo. Cov kev tshawb fawb tau pom tias qhov chaw tooj liab tuaj yeem tua ntau dua 99.9% ntawm cov kab mob hauv ob peb teev, suav nrog ntau hom tshuaj tua kab mob - tiv thaiv kab mob. Qhov no ua rau UNS C12200 cov raj tooj liab tshwj xeeb yog qhov zoo rau cov dej haus.
Fungi, xws li pwm, vam meej nyob rau hauv ib puag ncig moist, tab sis tooj liab cov tshuaj tiv thaiv kab mob txuas mus rau cov kab mob no thiab. Cov tooj liab ions tso tawm los ntawm lub raj nplaim inhibit qhov kev loj hlob thiab kev loj hlob ntawm fungi, tiv thaiv pwm tsim hauv cov kav dej.
2. Corrosion Resistance
Kev tiv thaiv corrosion ntawm UNS C12200 tooj liab raj yog ntaus nqi rau tooj liab qhov ruaj khov tshuaj. Nyob rau hauv cov dej feem ntau, txheej tiv thaiv ntawm tooj liab oxide los yog tooj liab carbonate ua rau saum npoo, tiv thaiv corrosion ntxiv. Qhov no ua rau cov raj tooj liab ua tau zoo heev nyob rau hauv ntau qhov chaw dej, suav nrog me ntsis acidic thiab me ntsis alkaline tej yam kev mob.
Hauv UNS C12200, ib qho me me ntawm phosphorus yog ntxiv rau deoxidation, uas txhim kho corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig nrog sulfides los yog lwm yam corrosive agents.
3. Zoo heev lub cev & cov cuab yeej cuab tam

GNEE's UNS C12200 tooj liab raj tuaj yeem tiv taus kev ua haujlwm siab ntawm4.0 MPa ntawm 65 degree(kwv yees li 580 psi ntawm 149℃F). Thaum muab tso rau hauv kev siv, lawv yuav tsis tawg lossis xau, thiab lawv lub neej yuav zoo li lub tsev.
FAQ
Q1: C12200 vs C11000 - Dab tsi yog qhov txawv?
A:C12200 muaj 0.015-0.04% phosphorus rau deoxidation, ua rau nws tiv taus hydrogen embrittlement thaum vuam lossis brazing. C11000 (electrolytic tawv pitch) muaj cov pa oxygen thiab yuav tawg yog welded nyob rau hauv ib tug txo qhov cua. C12200 muaj 85% IACS hluav taws xob conductivity; C11000 muaj 100% IACS. Rau cov kav dej thiab HVAC qhov twg yuav tsum tau brazing, C12200 yog qhov kev xaiv raug. Rau cov ntawv thov hluav taws xob siab uas tsis muaj vuam, C11000 zoo dua.
Q2: C12200 vs C10200 - uas zoo dua?
A:C10200 yog oxygen- tooj liab dawb nrog 99.95% tooj liab yam tsawg kawg nkaus thiab 0.001% oxygen siab tshaj plaws, muab 100% IACS conductivity. Nws yog siv rau siab - lub tshuab nqus tsev hluav taws xob thiab cov ntawv thov hluav taws xob tshwj xeeb. C12200 muaj phosphorus thiab muaj 85% IACS conductivity, tab sis nws raug nqi tsawg dua. Rau cov kav dej, HVAC, thiab kev tsim vaj tsev dav dav, C12200 yog tus qauv kev lag luam. C10200 yog qhov tsis tsim nyog overkill rau cov dej lossis cov tub yees kab.
Q3: ASTM B88 Hom L vs Hom M?
A:Hom L muaj phab ntsa tuab (rau 1/2 "OD: 0.049" phab ntsa tuab) thiab raug ntsuas rau siab dua. Nws yog tus qauv kev xaiv rau thaj chaw thiab kev lag luam cov kab kub thiab dej txias. Hom M muaj cov phab ntsa nyias nyias (1/2 "OD: 0.032" phab ntsa tuab) thiab tau txais kev pom zoo tsuas yog rau cov ntawv thov hauv tsev uas tsis tshua muaj siab. Ntau cov kav dej hauv zos tsis tso cai rau hom M rau dej kub lossis siv hauv av. Hom L muaj kev nyab xeeb dua rau feem ntau txoj haujlwm.
Q4: Hom K tooj liab raj siv rau dab tsi?
A:Hom K muaj cov phab ntsa tuab tshaj plaws (1/2 "OD: 0.065" phab ntsa tuab) thiab yog siv rau hauv cov dej hauv av, kev pabcuam nkag, thiab siab - cov tshuab siab. Nws muab kev tiv thaiv ntxiv tiv thaiv corrosion los ntawm av tej yam kev mob thiab sab nraud loads los ntawm backfill. Hom K kuj tau teev tseg rau cov tshuab tua hluav taws thiab cov kab hluav taws xob kho mob hauv tsev kho mob. Nws raug nqi ntau dua li Hom L tab sis siv sijhawm ntev dua hauv qhov chaw nruj heev.
Q5: Cov raj C12200 puas tuaj yeem siv rau cov dej haus?
A:Yog lawm, C12200 tau pom zoo los ntawm NSF / ANSI 61 rau cov dej haus. Tooj liab lub ntuj tshuaj tua kab mob tua 99.9% ntawm cov kab mob hauv ib teev, suav nrog Legionella thiab E. coli. Tsis zoo li cov kav dej yas, tooj liab tsis tso tshuaj rau hauv dej haus. Txawm li cas los xij, dej nrog pH qis dua 6.5 tuaj yeem ua rau tooj liab rau leach, yuav tsum tau hloov pH lossis kev tswj xyuas corrosion.
Q6: Puas yog C12200 xav tau cov koom haum dielectric nrog cov yeeb nkab steel?
A:Yog lawm. Thaum tooj liab thiab hlau txuas ncaj qha, galvanic corrosion tshwm sim vim tias ob lub hlau muaj qhov sib txawv hluav taws xob. Cov yeeb nkab steel yuav corrode sai, feem ntau hauv 1-2 xyoos. Ib lub koom haum dielectric (yas lossis roj hmab cais tawm) lossis tooj dag haum ntawm tooj liab thiab hlau tiv thaiv cov tshuaj tiv thaiv galvanic. Tsis txhob txuas tooj liab ncaj qha rau galvanized steel lossis hlau dub.
Q7: Cov raj C12200 puas tuaj yeem khoov yam tsis muaj cov cuab yeej tshwj xeeb?
A:Tsuas yog tias lub raj yog annealed (mos temper). Hard drawn C12200 raj yuav tawg los yog kink yog khoov yam tsis muaj annealing ua ntej. Rau thaj chaw khoov ntawm cov tooj liab mos, siv lub tes tsho bender lossis khoov lub caij nplooj ntoos hlav. Yam tsawg kawg khoov vojvoog rau cov tooj liab yog feem ntau 4-6 npaug ntawm txoj kab uas hla. Rau kev khoov nruj, sau lub raj nrog xuab zeb lossis siv lub mandrel bender los tiv thaiv kev sib tsoo.
Q8: Yuav ua li cas solder C12200 tooj liab raj kom raug?
A:Ntxuav lub raj kawg thiab haum rau hauv nrog txhuam los yog daim ntaub emery kom txog thaum ci. Siv flux rau ob qhov chaw. Sib sau ua ke thiab ua kom sov nrog lub teeb kom txog rau thaum cov npuas flux. Siv cov hlau lead-dawb solder rau qhov sib koom ua ke; Kev ua capillary yuav rub nws mus. Siv cov hlau lead -dawb solder (95% tin / 5% antimony lossis tin-silver) rau cov tshuab dej haus raws li Txoj Cai Dej Haus Zoo.
Q9: Dab tsi ua rau pinhole leaks hauv C12200 cov kav dej?
A:Pinhole leaks feem ntau yog tshwm sim los ntawm formicary corrosion, uas tshwm sim thaum tooj liab reacts nrog organic acids los ntawm decomposed ntoo, adhesives, los yog tu cov khoom. Lwm yam ua rau muaj xws li dej txhoj puab heev (pH qis dua 6.5, cov tshuaj chloride siab, lossis cov pa oxygen siab) thiab kev siv hluav taws xob tsis zoo. Txhawm rau tiv thaiv cov pinholes, tswj cov dej pH ntawm 6.5-8.5 thiab tsis txhob tso cov dej ntws tawm hauv cov pob qij txha.
Q10: C12200 raj lifespan hauv cov kav dej?
A:Hauv cov dej hauv nroog ib txwm muaj (pH 6.5-8.5, hardness nruab nrab), C12200 tooj liab raj kav 50-70 xyoo rau cov kab dej hauv tsev. Rau qhov zoo-tswj kaw-kawg hydronic cua sov tshuab, lifespan feem ntau tshaj 80 xyoo. Tooj tooj tiv thaiv oxide txheej txuas ntxiv hloov kho kom ntev li ntev tau dej chemistry tseem ruaj khov. Cov dej tsis zoo lossis kev teeb tsa tsis raug tuaj yeem txo lub neej mus rau 10-20 xyoo.
Q11: C12200 cov raj puas tuaj yeem khov thiab tawg?
A:Yog lawm. Thaum cov dej khov hauv lub raj tooj liab, nws nthuav dav li ntawm 9% thiab ua kom muaj siab txog li 40,000 psi, deb tshaj lub raj lub zog tawg. Lub raj yuav sib cais, feem ntau raws txoj kab ncaj nraim. Tsis zoo li cov yeeb nkab yas (PEX), tooj liab tsis tuaj yeem nthuav dav kom haum rau dej khov. Txhawm rau tiv thaiv kom tsis txhob khov, insulate cov kav dej hauv qhov chaw tsis muaj cua sov, tso cai rau cov faucets kom poob thaum huab cua txias, lossis siv cov ntaub nplaum kub.
Q12: DHP tooj liab yog dab tsi?
A:DHP sawv cev rau "Deoxidized High Phosphorus." Nws yog tib yam khoom siv raws li UNS C12200. Cov ntsiab lus phosphorus (0.015-0.04%) tshem tawm cov pa oxygen thaum yaj thiab txhim kho corrosion kuj. DHP yog lub npe nrov rau C12200 hauv European thiab Esxias kev lag luam. Yog tias koj pom DHP tooj liab raj, nws yog sib npaug rau ASTM B88 C12200 thiab tuaj yeem siv sib hloov.
