FAQ
Q1: Dab tsi yog qhov txawv ntawm ASTM B88 Hom K thiab Hom L tooj liab raj?
A:Hom K tooj liab raj muaj phab ntsa tuab dua li Hom L. Rau 1/2 "tube, Hom K phab ntsa tuab yog 0.049" thaum Hom L yog 0.040". Hom K yog siv rau cov dej hauv av hauv av thiab siab - cov tshuab siab vim tias nws tiv thaiv kev puas tsuaj sab nraud zoo dua. Hom L yog tus qauv rau sab hauv tsev thiab kev lag luam kav dej. Hom K tus nqi ntau dua li 2.
Q2: Dab tsi yog qhov txawv ntawm ASTM B88 Hom L thiab Hom M tooj liab raj?
A:Hom L tooj liab raj muaj phab ntsa tuab dua li Hom M. Rau 1/2 "tube, Hom L phab ntsa yog 0.040" thaum Type M phab ntsa tsuas yog 0.028". Hom L yog ntsuas rau siab dua thiab tau pom zoo rau cov dej kub thiab dej txias hauv txhua qhov kav dej. Hom M yog thinner thiab tsuas yog tso cai rau qis - siab siab tso cai rau ntau qhov chaw nyob hauv dej. kab.
Q3: Dab tsi yog cov xim xim rau ASTM B88 Hom K, L, thiab M tooj liab raj?
A:Hom K tooj liab raj yog cim nrog ntsuab xim code. Hom L tooj liab raj yog cim nrog xiav xim code. Hom M tooj liab raj yog cim nrog liab xim code. Cov cim xim no tau luam tawm raws qhov ntev ntawm lub raj rau kev txheeb xyuas yooj yim ntawm qhov chaw ua haujlwm. Cov neeg cog lus tuaj yeem txheeb xyuas lub raj hom los ntawm kev saib cov xim kab txaij yam tsis ntsuas phab ntsa tuab.
Q4: ASTM B88 Hom M tooj liab raj puas siv tau rau cov kab dej kub?
A:Nws nyob ntawm cov kav dej hauv zos. Qee cov lej tso cai rau hom M tooj liab raj rau cov kab dej kub hauv tsev vim tias kev ua haujlwm siab tsawg (40-80 psi). Txawm li cas los xij, ntau qhov chaw txiav txim siab thiab cov kws paub txog cov kav dej pom zoo rau Hom L rau cov dej kub vim tias Hom M cov phab ntsa nyias nyias muaj qhov cuam tshuam rau pitting corrosion thiab yaig dhau sijhawm. Rau cov tsev lag luam lossis cov tshuab kub siab (siab dua 140℃F), Hom L yog qhov pom zoo.
Q5: Dab tsi yog qhov txawv ntawm C10200, C12000, thiab C12200 rau ASTM B88 tooj liab raj?
A:C10200 yog oxygen- tooj liab dawb (99.95% Cu), siv rau cov ntawv tshwj xeeb. C12000 muaj phosphorus tsawg (0.004-0.012%), muab qee qhov deoxidation tab sis txwv weldability. C12200 muaj phosphorus ntau dua (0.015-0.040%), muab tag nrho deoxidation thiab zoo heev brazing / vuam zog. Rau cov kav dej uas yuav tsum tau brazing, C12200 yog tus qauv xaiv. C12000 tsis tshua muaj rau kev siv cov raj dej.
Q6: Kub O60 txhais li cas rau ASTM B88 tooj liab raj?
A:O60 yog ib qho mos mos annealed temper rau ASTM B88 tooj liab raj. Lub raj yog rhuab kom tsawg kawg yog 600℃F thiab txias maj mam, uas tshem tawm cov kev ntxhov siab sab hauv thiab ua rau lub raj muaj zog heev. O60 raj tuaj yeem khoov tau yooj yim thiab flared ntawm tes siv cov cuab yeej yooj yim. Nws muaj nyob rau hauv ob qho tib si ncaj lengths thiab coils. O60 yog qhov kub siab tshaj plaws rau cov kav dej tooj liab vim tias qhov chaw khoov feem ntau xav tau thaum lub sijhawm teeb tsa.
Q7: Npaum H58 txhais li cas rau ASTM B88 tooj liab raj?
A:H58 yog ib qho nyuaj kos rau ASTM B88 tooj liab raj. Lub raj yog txias ua hauj lwm (kos) thiab tsis annealed, yog li nws tuav lub zog siab (tsawg kawg 36 ksi tensile zog vs . 30 ksi rau annealed). H58 raj yog ncaj thiab nruj, siv rau ntev ncaj khiav qhov twg khoov tsis tas yuav tsum tau. H58 tsis tuaj yeem khoov yam tsis muaj kev tawg tshwj tsis yog tias nws yog annealed ua ntej. Nws feem ntau yog siv rau cov khoom siv loj hauv cov tsev lag luam.
Q8: Dab tsi yog qhov tawg siab ntawm ASTM B88 Hom L 1/2" tooj liab raj?
A:Rau 1/2 "Type L tooj liab raj (0.040" phab ntsa thickness), qhov tawg siab ntawm chav tsev kub yog kwv yees li 2,800-3,000 psi. Kev nyab xeeb ua haujlwm siab yog derated rau 1/4 ntawm qhov tawg siab, lossis txog 700-750 psi. Rau cov dej kub ntawm 180℃F, txo kev ua haujlwm siab los ntawm 15-20% vim tooj liab lub zog txo qis ntawm qhov kub siab. Cov dej nyob hauv tsev siab yog 40-80 psi, zoo nyob rau hauv kev txwv tsis pub muaj kev nyab xeeb.
Q9: Vim li cas ASTM B88 tso cai C10200, C12000, thiab C12200 rau tooj liab raj?
A:ASTM B88 tso cai rau ntau qib tooj liab vim tias cov ntawv thov sib txawv muaj cov cai sib txawv. C10200 (oxygen- pub dawb) yog rau tshwj xeeb siab - conductivity lossis siab - lub tshuab nqus tsev. C12000 (tsawg phosphorus) yog qib qub tseem muaj nyob hauv qee cov khoom muag. C12200 (tus qauv phosphorus{10}}deoxidized) yog feem ntau vim nws tiv thaiv hydrogen embrittlement thaum lub sij hawm brazing. Rau feem ntau cov kav dej ua haujlwm, C12200 yog qhov pom zoo thiab feem ntau muaj qib.
Q10: Dab tsi yog qhov hnyav ntawm ASTM B88 Hom L 1 "copper raj ib ko taw?
A:ASTM B88 Hom L 1 "copper raj muaj phab ntsa tuab ntawm 0.050" thiab hnyav kwv yees li 0.655 phaus ib ko taw. Rau tus qauv 20-foot ntev, lub raj hnyav txog 13.1 phaus. Qhov hnyav no muaj txiaj ntsig zoo rau kev suav cov nqi thauj khoom thiab txiav txim siab qhov sib nrug. Rau kev sib piv, Hom K 1 "tube hnyav 0.839 lb / ft (hnyav), thiab Hom M 1" raj hnyav 0.465 lb / ft (teeb).
