Ob Phosphorus -Deoxidized Coppers
Copper tubing yog dav siv thoob plaws HVAC, kav dej, tub yees, thiab cov kua dej ua haujlwm. Thaum ob qho tib si TP1 thiab TP2 yog phosphorus -deoxidized tooj liab raj, lawv ua haujlwm sib txawv raws li cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab cov yam ntxwv ua haujlwm.
Kev sib piv tshuaj lom neeg
Ob qib muaj tooj liab ntxiv rau nyiaj tsawg kawg yog 99.9 feem pua thiab cov pa oxygen ntawm 0.01 feem pua siab tshaj plaws. Thawj qhov sib txawv yog cov ntsiab lus phosphorus: TP1, C12000, muaj 0.004 txog 0.012 feem pua, thaum TP2, C12200, muaj 0.015 txog 0.040 feem pua. Lwm yam impurities yog nruj tswj ntawm 0.1 feem pua tag nrho rau ob qho tib si.
Mechanical Properties Sib piv
TP1 muaj lub zog tensile ntawm 215 mus rau 345 MPa thiab tawm los ntawm 60 mus rau 300 MPa nyob ntawm qhov kub thiab txias, nrog elongation ntawm 25 mus rau 45 feem pua ntaus. TP2 muaj lub zog tensile ntawm 210 mus rau 340 MPa thiab tawm los ntawm 55 mus rau 295 MPa nrog elongation ntawm 25 mus rau 40 feem pua ntawm cov annealed. TP1 feem ntau muaj qhov zoo dua me ntsis ductility, thaum ob qho tib si muaj zog qaug zog rau kev siv zog siab.
Lub cev thiab kev ua haujlwm zoo
TP1 muaj hluav taws xob conductivity ntawm 85 feem pua IACS thiab thermal conductivity ntawm 350 W ib meter ib Kelvin. TP2 muaj txog 80 feem pua IACS thiab 330 W ib meter ib Kelvin. Brazability thiab weldability yog zoo heev rau TP1 thiab zoo heev rau TP2, vim hais tias cov phosphorus cov ntsiab lus siab dua pab capillary txaus thaum brazing. Ob leeg muaj kev tiv thaiv corrosion zoo heev thiab txias khoov kev ua tau zoo nyob rau hauv cov mob annealed.
Daim ntawv qhia kev
Xaiv TP1 rau cov cua kub exchanger raj, tub yees thiab ACR raj, hydraulic thiab pneumatic kab, roj thiab roj kab, thiab hluav taws xob busbars qhov twg conductivity thiab qaug zog kuj tseem ceeb. Xaiv TP2 rau cov kav dej kav dej, HVAC cov kab tub yees nrog cov brazing dav, thiab cov kav dej kho mob uas muaj kev ntseeg siab yog qhov tseem ceeb. Rau cov ntawv thov uas xav tau qhov sib npaug ntawm kev coj ua thiab kev sib koom ua ke, ob qho tib si yuav raug txiav txim siab thiab qhov kev xaiv zaum kawg dictated los ntawm tus nqi thiab muaj.
Cov qauv
Ob qib yog them raws li ASTM B75 rau seamless raj, B88 rau raj dej, B280 rau ACR raj, EN 12735-1, JIS H3300, thiab NSF / ANSI 61 rau haus dej systems.
