1. ASTM A671 CC60 Class 42 yog dab tsi?
Txhais: High -kev ua tau zoo hluav taws xob- fusion-welded (EFW) yeeb nkab tsim los rauheev-siab thiab qis- qhov kev pabcuam kub, ua tau raws li kev nruj kev lag luam thiab lub zog sector xav tau.
Cov ntsiab lus tseem ceeb:
Yield zog: 60 ksi (414 MPa) ntawm-20 ° F (-29 ° C).
Kev ntsuas siab: 40,000 psi (2,758 bar)(Qeb 42).
Khoom siv: Carbon steel nrogultra{0}}siab toughness(Charpy V-notch Ntau dua lossis sib npaug li 50 ft-lb ntawm-50 ° F / -45 ° C).
2. Qhov twg nws feem ntau siv?
Roj & Roj:
Ultra{0}} cov kav dej tob (>8,000m).
Siab -cov pa roj txhaj tshuab(HP / HT reservoirs).
Kev lag luam:
Supercritical CO₂ thaujnyob rau hauv advanced zog voj voog.
Nuclear fusion reactor coolant loops(tsis yog-xov tooj cua zones).
3. Cov Khoom Siv & Cov Khoom Siv Xeem
| Khoom | Kev xav tau | Test Standard (ASTM) |
|---|---|---|
| Hydrostatic Test | 1.5x tsim siab (60,000 psi) | A671 Tshooj 12 |
| Charpy Impact | Ntau dua lossis sib npaug li 50 ft-lb (68 J) ntawm-50 ° F (-45 ° F) | A673 (Pab pawg 4+) |
| NDT | Phaseed -array UT + digital radiography | E2704 / E1032 |
4. Kev tsim khoom & Kev lees paub zoo
Txheej txheem:
Laser -hybrid vuamnrog AI-lub zog tiag tiag- tshawb pom qhov tsis xws luag.
Quench & temper + PWHT(yuav tsum tau rau txhua thicknesses).
Daim ntawv pov thawj:
Ua raws liASME B31.3 Chav Kawm 4, API 5L PSL4X UAS, thiabTS EN ISO 3183: 2030.
NACE MR0175 Level VII (sour service with H₂S >100 ppm).
5. Kev txwv kev ua haujlwm & kev ua raws cai
Qhov kub thiab txias: -50 ° F txog 1,100 ° F (-45 ° F txog 593 ° F).
Max Siab: Tsawg dua lossis sib npaug rau 40,000 psi (2,758 bar).
Cov qauv tseem ceeb:
TS EN ISO 3183: 2030(Ultra-siab- cov kav dej siab).
