ASTM A333 / A333M GR.6 Seamless Steel Pipes piav qhia
A333Gr6 cryogenic hlab yog seamless steel raj tsim rau cov ntawv thov cryogenic, ua raws li ASTM A333 / ASME SA333 cov qauv. Lawv feem ntau yog siv rau hauv cov khoom siv petrochemical (xws li reactors, heat exchangers, thiab separators), natural gas processing, and cryogenic equipment manufacturing in environments range from -45℃to -195℃. Cov ntaub ntawv qib npog ASTM A333Gr1 txog Gr11, nrog rau cov kev qhia tshwj xeeb suav nrog cov kab uas hla ntawm 21.3-762mm thiab phab ntsa thicknesses ntawm 2.0-140mm. Lawv tau tsim los siv kub dov, kos duab txias, lossis cov txheej txheem kub nthuav dav thiab xav tau kev kho cua sov ntawm 900℃~ 930℃thaum xa khoom.

A333 GR6 VS A106 GRB
| Sib piv Aspect | A333 GR.6 | A106 GR.B |
|---|---|---|
| Daim ntawv thov tseem ceeb | Tsawg-kev pabcuam kub (piv txwv li, ib puag ncig cryogenic, LNG nroj tsuag) | High -kev pabcuam kub (xws li, lub zog tsim hluav taws xob, refineries, chav tshuab) |
| Khoom siv | Cov pa roj carbon steel nrog nruj tswj ntawm impurities (S, P) rau kev txhim kho qis -temp toughness; yuav tsum muaj kev ntsuam xyuas | Carbon steel nrog me ntsis siab dua cov ntsiab lus carbon; tsom rau siab -temp lub zog |
| Mechanical Properties | - Tensile zog: 485 MPa (70,000 psi) min - Yield zog: 275 MPa (40,000 psi) min - High ductility ntawm qis temps |
- Tensile zog: 415 MPa (60,000 psi) min (vim nrog tuab) - Yield zog: 240 MPa (35,000 psi) min - Zoo siab - kev ua haujlwm kub |
| Kev xeem yuav tsum tau | Yuav tsum tau kuaj xyuas ntawm -50℃F (-45 degree) lossis txias dua; nruj zoo tswj rau toughness | Tsis tas yuav tsum tau kuaj xyuas; tsom rau kev ntsuas tensile/hardness rau siab -temp kev ncaj ncees |
| Tus nqi cuam tshuam | Feem ntau kim dua vim kev tswj hwm nruj dua thiab kev sim | Tus nqi ntau dua -zoo rau siab -temp apps uas qis -temp perf tsis tseem ceeb |
| Kev lag luam Standards | ASTM A333 / ASME SA333 Cov Lus Qhia | ASTM A106 / ASME SA106 |
| Thaum siv | - Ib puag ncig Arctic - LNG systems - Qhov twg muaj kev cuam tshuam toughness ntawm cryogenic temps yog qhov tseem ceeb |
- Boilers - Kub exchangers - Chav kab - Qhov twg tus nqi- kev ua tau zoo yog qhov tseem ceeb thiab qis -temp perf tsis tas yuav tsum tau |
