A Tooj Liab Teeyog cov yeeb nkab haum zoo li tsab ntawv "T," siv los txuas rau hauv lub cav tooj liab lossis cov roj liab, thiab yooj yim, thiab yooj yim ntawm kev teeb tsa hauv ntau yam Kev Siv .
| Ntiag tug |
Cov txiaj ntsig / Cov Cwj Pwm |
| Lub zog tensile |
200-250 mpa (rau tus tooj liab zoo nkauj); siab dua nyob rau hauv alloys (e {{{2} g}, tooj dag lossis tooj daj lossis tooj daj lossis tooj to} mpa. |
| Paib lub zog |
70-100 mpa (tooj liab), nyob ntawm temper (annealed vs. nyuaj-kos). |
| Elongation thaum so |
20-40% (Kev ua kom siab siab tso cai rau khoov thiab shaping yam tsis muaj kev tawg) . |
| Kev nyuaj |
50-80 HB (Brinell hardness rau annealed tooj liab); nce nrog kev ua haujlwm txias lossis siv . |
| Siab Ntsuam |
Feem ntau ntsuas rau 1, {000}}}}} {} psi (Haum rau feem ntau ntawm cov khoom siv thiab kev lag luam lag luam). |
| Ductility / mallabability |
Zoo heev; tuaj yeem siv cov yas, brazed, lossis mechanically koom ua yam tsis muaj fracturing . |
Feem ntau cov tooj liab Tees rau cov raj xa dej yog tsim los ntawmNtshiv dawb huv (CU ntau dua los yog sib npaug rau 99.5%)lossis tshwj xeeb tooj liab alloys, nyob ntawm daim ntawv thov:
Ntshiab Tooj (E {{{0} g .}}}}}, Astm B88 Tooj Liab)
Muaj pes tsawg: Cu ntau dua lossis sib npaug rau 99 . 9%}}}}}}}!
Tooj liab alloys (muaj ntau yam nyob rau hauv Tees Tshwj Xeeb)
Tooj dag (tooj liab-zinc alloy): CU (60-90%), ZN (10-440%); yuav suav nrog txhuas (rau machinity) lossis tin (rau corrosion tsis kam) .
Bronze (tooj liab-tin alloy): CU (80-95%), SN (5-20%); yuav suav nrog txhuas, npib tsib xee, lossis phosphorus rau txhim kho lub zog .
Tooj liab Tees yog siv nyob rau ntau qhov kev lag luam rau kev faib cov kua thiab cov ceg:
Txuas Txuas Cov Khoom Siv Dej (E {. g {}}}}}}}}
Roj Pipelines (nkev lossis cov khoom siv) nyob rau hauv cov vaj tse thiab cov vaj tse ua lag luam .
Cov cua sov lub tshuab (dej kub lossis dej chav dej) hauv cov kab tawg, cov rwj, thiab convectors .
Lub tshuab txias txias (txias kab hauv cov chav ua cua txias) .
Tshuaj lom neeg cov nroj tsuag (rau cov kua tsis muaj ntshav thauj) .
Khoom noj khoom haus thiab dej haus hauv kev lag luam (vim tooj liab lub kev nyiam huv thiab tsis muaj tshuaj lom) .
Cov ntawv thov marine (ntsev ua haujlwm tsis txaus ntseeg hauv cov kav dej tuam av nkoj) .
Sprinkler cov tshuab, qhov chaw uas tooj liab kev ntseeg siab thiab corrosion tsis kam yog tseem ceeb .
