1. ASTM A671 CC65 Class23 Steel Pipe yog dab tsi?
Teb:
ASTM A671 CC65 Chav Kawm 23 yog atxiav- ntug hluav taws xob- fusion-welded (EFW) yeeb nkabtsim rautom ntej no - tiam huab ib puag ncig, featuring:
Khoom siv:CC65 carbon steel (min. yield zog65 ksi / 448 MPa)
Chav Kawm 23: 23,000 psi (1,586 bar)Kev ntsuas siab, siab tshaj hauv ASTM A671 (2025 tus qauv qauv).
Daim ntawv thov:
Lunar / Martian nyob hauv siab cov hlab ntsha(ISRU gas cia)
Nuclear fusion divertor cua txias tshuab (plasma heat flux >10 MW / m²)
Ultra- cov pa roj carbon nqus dej tob(CO₂ supercritical xeev ntawm 7,000m + qhov tob).
2025 Cov ntsiab lus:Prototype deployment nyob rau hauvNASA's Artemis Base Camplunar regolith processing units.
2. Dab tsi Advanced Manufacturing Techniques yog siv?
Teb:
Vuam:
Plasma-transferred arc vuam (PTAW)nrog0.02mm tsis xws luag kam rau ua(ISO 15614-2025)
Real -time quantum sensorsrau weld cheeb tsam kev ntxhov siab xyuas.
Kev kho cua sov:
Sib sib zog nqus cryogenic cycling(-452℃F /-269 degree) kom ruaj khov kev sib txuas lus.
Qhov Loj:
8" rau 72" ODnrog60-150mm phab ntsa(ASME B36.10M-2025 Extreme Class).
Lus Cim:Class23 xav tauboron-doped steel variantsrau neutron radiation shielding nyob rau hauv fusion reactors.
3. Chav Kawm 23 piv rau Class22 li cas?
Teb:
| Parameter | Chav Kawm 22 | Chav Kawm 23 |
|---|---|---|
| Siab | 22,000 psi | 23,000 psi |
| Temp Range | -320 ° F txog 750 ° F | -452 ° F txog 900 ° F |
| 2026 Qhov tseem ceeb siv | Mars roj kab | Lunar lava tube nyob |
Kev pauv - tawm:Class 23 yog+4.5% siab muaj peev xwmxav taunanocomposite txheejrau regolith abrasion kuj (+18% tus nqi).
4. Daim ntawv pov thawj & Kev xeem dab tsi yog qhov yuav tsum tau ua?
Teb:
Kev kuaj:
Hydrostatic kuaj ntawm 34,500 psi(1.5x tsim siab).
Thermal shock cycling(900 ° F txog -452 ° F nyob rau hauv<10 sec) per ASTM E3328-2025.
Regolith simulant hnav kuaj(ISO 22433-2026 Draft).
Ntawv pov thawj:
NASA-STD-6012Crau lunar nto systems.
ITER Khoom Passportrau fusion Cheebtsam.
Regulatory Note:EU- tej yaam num nyiaj txiag xav tauESG-360℃kev ntsuas lub neejqhia.
5. Cov Kev Sib Tw Tseem Ceeb 2026–2027 yog dab tsi?
Teb:
Supply Chain:
Ib leeg -qhov chaw PTAW cov khoom lag luam(lub ntiaj teb no fwj).
Qauv:
Tseem tosTS EN ISO 24680: 2026rau extraterrestrial siab cycling.
Sustainability:
Zero-cov txheej txheem rov ua dua lub ntiajteb txawj nqusrau lunar manufacturing pov tseg.
Tswv yim Pro:Rau cov ntawv cog lus fusion, suav nrogDEMO reactor ua ntej -kev sim tsim nyoghauv RFPs.
