Vim li cas C12200 Dominates Kub thiab Txias Piping
C12200 yog phosphorus deoxidized tooj liab uas muaj 99.90% yam tsawg kawg nkaus tooj liab ntxiv rau nyiaj thiab 0.015 - 0.040 % phosphorus. Nws paub nyob rau hauv lub npe hu ua Cu-DHP hauv EN, CW024A hauv DIN CEN/TS 13388, C12200 hauv UNS, C106 hauv BS thiab TP2 hauv GB/T 5231. Cov ntsiab lus phosphorus deoxidizes cov yaj, yog li cov hlau tsis muaj residual oxidation thiab cuproem oxide. cuam tshuam rau lub suab tawv tawv thaum nws yog brazed los yog annealed nyob rau hauv ib tug txo qhov cua.
Kev sib xyaw ua ke ntawm cov thermal conductivity, siab hluav taws xob conductivity, corrosion kuj thiab yooj yim fabrication piav qhia vim li cas tooj liab raj tau dhau los ua tus qauv xaiv rau cov kav dej, cua sov thiab cua txias circuits nyob rau hauv cov tsev nyob thiab cov lag luam. Cov yeeb nkab tooj liab muaj lub zog siab, khoov thiab flares yam tsis muaj kev tawg, thiab ua kom nws txoj kev ntseeg ruaj khov nyob rau hauv cov te thiab cuam tshuam kev thauj khoom, yog li kev teeb tsa uas raug tsim yuav tsum tau ua tib zoo saib xyuas nws lub neej.

Lub raj dej yog txiav txim siab rau ASTM B88, uas txhais tau hais tias peb chav phab ntsa tuab siv thoob plaws hauv kev lag luam: hom K nrog cov phab ntsa hnyav tshaj plaws, hom L nrog cov phab ntsa nruab nrab thiab hom M nrog cov phab ntsa lightest. Rau ib nrab nti nominal raj cov phab ntsa siv yog li 0.049 rau hom K, 0.040 rau hom L thiab 0.028 rau hom M, yog li peb hom yog xaiv los ntawm lub siab thiab faus neeg mob ntau dua li txoj kab uas hla ib leeg. Cov ntaub ntawv ntsig txog suav nrog ASTM B75 / B75M rau seamless tooj liab raj, ASTM B42 rau seamless tooj liab yeeb nkab nyob rau hauv tus qauv qhov ntau thiab tsawg, ASTM B111 thiab ASME SB111 rau condenser thiab kub exchanger raj, ASTM B395 thiab ASTM B359 rau U-bend bar, 8 thiab fin. GB / T 1527 thiab JIS H3300 suav nrog Suav thiab Nyij Pooj sib npaug, thiab EN 1057 qhia cov raj tooj liab rau cov dej thiab roj hauv kev huv thiab cua sov hauv cov tempers R220, R250 thiab R290.
Lub cev thiab kev pabcuam
Cov txiaj ntsig zoo yog qhov ntom ntawm 8.94 g / cm³, melting point ntawm 1083 degree, hluav taws xob conductivity tsawg kawg yog 85% IACS, thermal conductivity ntawm txog 390 W / (m·K), coefficient ntawm thermal expansion ntawm roughly 17 x 10⁻⁶ ib K thiab ib qho qauv ntawm 71 G. Kub ua hauj lwm yog ua los ntawm 760 thiab 871 degree. Cov hlau ua kom muaj txiaj ntsig zoo los ntawm qhov kub thiab txias mus txog qhov kev txwv ntawm fittings thiab cov ntaub ntawv sib koom ua ke, uas yog vim li cas tib lub raj siv dej txias, dej kub hauv tsev thiab tsis tshua muaj siab chav condensate.
Vim hais tias C12200 yog deoxidized, nws yog tsim rau annealing, brazing thiab welding, tab sis lub raj sib dhos yuav tsum tseem yuav tsum tau koom nrog cov txheej txheem kom raug kom tsis txhob muaj cua sov nyob ib ncig ntawm cov hlau kub. Qhov twg lub raj yog khoov, lub annealed temper yog xaiv; qhov twg txhav lossis kev txhawb nqa qhov sib txawv, siv lub zog rub lub raj.
Qhov ntau thiab tsawg, daim ntawv thov thiab kev tswj kom zoo
Sab nraud txoj kab uas hla yog muab los ntawm 6 hli mus rau 260 hli nyob rau hauv qhov ntau thiab tsawg ntawm cov raj dej, nrog rau cov pob zeb dav dav ntawm 2 hli mus rau 914 hli thiab phab ntsa thickness ntawm 0.2 hli mus rau 120 hli rau cov seem tshwj xeeb. Lengths ntawm 1 m, 2 m, 3 m thiab 6 m yog tuav, coils muaj rau me me diameters, thiab txiav lengths yog tsim los rau kos duab. Cov ntawv thov suav nrog kev faib dej kub thiab dej txias hauv tsev, cua sov hydronic thiab cua txias, cov kav dej, kev kho mob roj, cov kab dej, cov tub yees thiab cua txias, condensers, evaporators, hnub ci thermal circuits, earthing conductors thiab cov khoom siv tiv thaiv corrosion xws li xov hlau, cables, conductive screws thiab cov ntim tshuaj.
Kev tshuaj xyuas suav nrog kev tshuaj xyuas tshuaj los ntawm spectrometer, tensile thiab hardness test, grain loj checks ntawm annealed raj, seem thiab phab ntsa thickness pov thawj, eddy tam sim no xeem, thiab hydrostatic siab kuaj qhov yuav tsum tau. Tube kawg yog deburred, nto yog tswj rau oxidation thiab huv si, thiab txhua lub tshav kub yog xa mus nrog ib tug zeb xeem daim ntawv pov thawj hais txog cov muaj pes tsawg leeg thiab txhua yam tshwm sim. Export packing siv yas zaj duab xis nrog ntoo rooj plaub los yog hlau -stripped bundles los tiv thaiv lub raj los ntawm hiav txwv, rail thiab huab cua thauj.
Cov lus nug nquag
Q: C12200 txhais li cas?
A: C12200 yog UNS lub npe rau phosphorus deoxidized siab phosphorus tooj liab, hu ua Cu-DHP hauv EN, CW024A hauv DIN CEN / TS 13388 thiab TP2 hauv GB / T 5231, nrog 99.90 % yam tsawg kawg nkaus {{7} tooj liab} ntxiv rau nyiaj.

Q: C12200 lub raj puas tuaj yeem welded?
A: Yog. Vim hais tias cov tooj liab yog deoxidized tag nrho nws tuaj yeem welded, brazed thiab soldered yam tsis muaj hydrogen embrittlement txaus ntshai ntawm tawv pitch tooj liab, tab sis cov pob qij txha yuav tsum ua raws li cov txheej txheem tsim nyog.
Q: Puas yog lub raj dej tooj liab corrode hauv dej txhoj puab heev?
A: Copper resists corrosion nyob rau hauv feem ntau potable dej thiab tsim ib tug tiv thaiv nto zaj duab xis. Tsis tshua muaj pH, siab chloride lossis siab khiav ceev yuav tsum tau tshuaj xyuas tiv thaiv lub raj phab ntsa tuab ua ntej xaiv.
Q: Daim ntawv pov thawj thiab ntim khoom yog dab tsi?
A: Txhua lub tshav kub tuaj nrog daim ntawv pov thawj zeb xeem npog cov tshuaj muaj pes tsawg leeg thiab cov khoom siv tshuab. Packing yog yas zaj duab xis nrog ntoo rooj los yog strapped bundles, haum rau hiav txwv, huab cua thiab courier shipping.
