ASTM A671 CJF115 Chav Kawm 62 yog dab tsi?
Qhov kev qhia tshwj xeeb no txhais qhov siab tshaj plaws - qib hluav taws xob- fusion-welded steel yeeb nkab hauv A671 series, featuring:
2.25% nickel alloy muaj pes tsawg leeg (CJF115)
Cryogenic kev pabcuam muaj peev xwm mus txog -75℃F (-60 degree)
Chav Kawm 62 qhia txog 62,000 psi (427 MPa) hydrostatic test siab
Txhim kho cov kev xav tau dhau ntawm Chav Kawm 61 rau cov ntawv thov tseem ceeb
--Cov ntawv thov tseem ceeb yog dab tsi?
Ultra-high pressure LNG transportation systems (>600 psi ua haujlwm siab)
Tom ntej no - tiam hydrogen cia thiab tsheb thauj mus los infrastructure
Nuclear fusion reactor cryogenic ntim tshuab
Sib sib zog nqus- hiav txwv mining thiab cov cuab yeej tshawb nrhiav Arctic
Tshwj xeeb aerospace cryogenic roj systems
--Qhov kev tsim kho kom zoo dua yog dab tsi?
Triple -welded kev tsim kho (hauv paus, sau, thiab hla dhau) nrog 100% automated UT/RT
Extended Charpy V-kev ntsuas ntsuas ntawm -100℃F (-73 degree) rau kev nyab xeeb
Khoos phis tawj - tswj quenching thiab tempering txheej txheem
Hardness txwv rau 185 HBW siab tshaj plaws nrog PWHT cov ntaub ntawv
Tag nrho traceability los ntawm raw khoom mus rau cov khoom kawg
--Cov khoom siv tshuab dab tsi yuav tsum tau lees paub?
Tensile zog: 85-110 ksi (586-758 MPa)
Yield zog: Ntau dua los yog sib npaug rau 55 ksi (379 MPa)
Elongation: Ntau dua lossis sib npaug li 20% hauv 2 ntiv tes
Impact toughness: 35 ft -lb yam tsawg kawg nkaus ntawm -60 degree
Fracture toughness (CTOD) kuaj rau cov ntawv thov tseem ceeb
--Class 62 txawv li cas ntawm cov chav kawm dhau los?
3.3% kev ntsuas siab dua li Chav Kawm 61 (62k vs 61k psi)
17% tougher tej yam yuav tsum tau (35 vs 30 ft-lb)
Ntxiv CTOD Kev Tshawb Fawb Txog Kev Kho Mob
Kev tswj cov tshuaj muaj pes tsawg leeg nruj dua
Yuav tsum tau thib peb-kev tshuaj xyuas rau txhua qhov ntau lawm
