Khoom Parameters
ASTM A333 Gr.1; Gr.6 Seamless Steel Tubes thiab yeeb nkab
Khoom Specification
ASTM A333 yog tus qauv specification rau seamless thiab welded steel yeeb nkab tsim los rau cov kev pab cuam cryogenic. Cov kav dej no yog tsim los rau ib puag ncig uas qhov kub thiab txias yuav poob qis thaum tswj lawv cov khoom siv kho tshuab thiab kev ua haujlwm zoo. Cov kev qhia tshwj xeeb suav nrog ntau qib, ntawm qib 1 thiab Qib 6 yog qhov feem ntau siv.

| Sulfur (S) | 0.025 max | 0.025 max |
| Silicon (Si) | 0.10 min | 0.10 min |
| Nickel (Ni) | - | 0.40 max |
Mechanical Properties
Cov khoom siv kho tshuab ntawm ASTM A333 Gr.1 thiab Gr.6 yog tsim los xyuas kom muaj kev ua tau zoo nyob rau hauv qis- qhov kub thiab txias:
| Khoom | Gr.1 | Gr.6 |
| Tensile zog (MPa) | 380 min | 415 nqi |
| Yield zog (MPa) | 205 feeb | 240 feeb |
| Elongation (%) | 30 feeb | 30 feeb |
Lub cev muaj zog
Lub cev lub cev ntawm cov qib no yog qhov tseem ceeb rau lawv daim ntawv thov hauv ntau qhov kev lag luam:
| Khoom | Tus nqi |
| Qhov ceev (g / cm³) | 7.85 |
| Melting Point (zeeg) | 1425-1540 |
| Thermal conductivity (W / m · K) | 50.2 |
Txheej Txheem Kev Ua Haujlwm
Cov txheej txheem kev ua tau zoo ntawm ASTM A333 Gr.1 thiab Gr.6 yog tus cwj pwm los ntawm lawv lub peev xwm los welded thiab tsim:
| Txheej txheem | Kev ua tau zoo |
| Weldability | Zoo |
| Formability | Zoo |
| Machineability | Nruab nrab |
Qib Steel
ASTM A333 Gr.1 thiab Gr.6 yog ob qho tib si siv hauv cov ntawv thov cryogenic. Gr.6 feem ntau yog siv, thaum Gr.1 yog haum rau cov ntawv thov cryogenic qhov twg kub qis dua. Gr.1 kuj pheej yig dua, thaum Gr.6 tau txhim kho cov khoom siv kho tshuab, ua rau nws tsim nyog rau kev thov ntau dua. Ob qib yog siv dav hauv kev lag luam uas muaj kev ntseeg siab thiab kev nyab xeeb yog qhov tseem ceeb.
Daim ntawv thov
Cov seamless steel raj thiab cov kav dej no feem ntau siv hauv:
Kev lag luam roj thiab roj: Rau kev thauj mus los ntawm cov kua thiab roj.
Petrochemical cog: Hauv cov chav ua haujlwm uas qhov kub tsis tshua muaj tshwm sim.
Lub zog tiam: Hauv cov tshuab xav tau cov kav dej ruaj khov thiab txhim khu kev qha.
Cryogenic Applications: Qhov twg cov ntaub ntawv yuav tsum tau ua nyob rau ntawm qhov kub tsis tshua muaj siab.
Cov qhab nia xaiv tau
Thaum ASTM A333 Gr.1 thiab Gr.6 yog cov kev xaiv nrov, lwm qib yuav raug txiav txim siab raws li cov cai tshwj xeeb:
ASTM A 334 Cov khoom siv: Lwm qhov qis -kub steel yeeb nkab specification.
ASTM A106 1: Haum rau siab - qhov kub thiab txias.
ASTM A335 Cov Lus Qhia Tshwj Xeeb: Rau siab - kub thiab siab - kev siv siab.
