1. ASTM A671 CJF115 Class 70 yog dab tsi?
Covqhov kawg - qibspecification rau hluav taws xob-fusion-welded kav, sib txuas:
CJF115: 2.25% nickel- alloyed carbon steel rau-75 ° F (-60 ° C)kev pabcuam cryogenic.
Chav Kawm 70: 70,000 psi (483 MPa)Hydrostatic xeem siab -qib siab tshaj hauv ASTM A671.
2. Nws tsuas yog xa mus rau qhov twg?
Raudaim ntawv thov ciam tebxav tauib txhij siab siab thiab cryogenic kev ua tau zoo:
LNG megaprojects(piv txwv li, 20,000 psi offshore kis tau tus mob)
Nuclear fusion reactor cryogenic ntim
Mars lub hom phiaj cryofuel systems
Tom ntej no -gen hydrogen pipelines(15, 000+ psi)
Sib sib zog nqus- hiav txwv mining umbilicalshauv cheeb tsam polar.
3. Dab tsi yog nws txoj kev tsim khoom zoo?
AI-zoo laser-arc hybrid vuamnrog 100% phased-array UT + AI defect detection.
Extended Charpy xeemntawm-112 ° F (-80 ° C) (60 ft -lb yam tsawg kawg nkaus).
Nanostructured Q&T txheej txheemrau grain refinement.
Hardness txwv: 175 HWB(nrog PWHT blockchain validation).
Digital ntxaibrau tag nrho lifecycle taug qab.
4. Certified mechanical zog?
TensileUa haujlwm siab: 95-120 ksi (655-827 MPa)
Yield: Ntau dua lossis sib npaug rau 65 ksi (448 MPa)
Elongation: Ntau dua lossis sib npaug li 20% (siab -cov ntawv thov kev nyuaj siab)
Fracture toughness: CTOD Ntau dua lossis sib npaug ntawm 0.25mm ntawm -60℃.
5. Chav kawm 70 zoo li chav kawm 63 li cas?
11% siab dua(70k vs . 63k psi).
20% tawv duacuam tshuam tsis kam (60 vs . 50 ft-lb).
Ua ntej yuav tsum taunanoscale microstructure tsom xam.
