1. ASTM A671 CJF115 Chav Kawm 72 yog dab tsi?
Covtom ntej no - tiam specificationrau cryogenic welded kav, featuring:
CJF115: 2.25% npib tsib xee- hloov kho steel rau-85 ° F (-65 ° F)tsis tshua muaj siab -kev pabcuam kub.
Chav Kawm 72: 72,000 psi (496 MPa)Hydrostatic xeem siab -redefining kev lag luam txwv.
2. Nws cov ntawv thov puas nyob qhov twg?
Tsim los rautej yaam num frontierxav tauib txhij ultra-siab siab thiab sib sib zog nqus cryogenic kev ua tau zoo:
LNG quantum pipelines(30, 000+ psi kis tau tus mob).
Fusion reactor superconducting hlau nplaum tshuab.
Interplanetary propulsion cryofuel kab.
Terawatt hydrogen zog cia.
Arctic subsea robotic mining systems.
3. Dab tsi yog qhov kev tsim khoom siv thev naus laus zis uas nws siv?
Nanoparticle- txhawb nqa hybrid vuamnrog AI-lub zog tiag tiag- tshawb pom qhov tsis xws luag.
Cryo- kev sim cuam tshuamntawm-120 ° F (-84 ° C) (75 ft -lb yam tsawg kawg nkaus).
