ASTM A671 CJP 115 Chav Kawm 22 Hlau Yeeb Nkab

1. ASTM A671 CJP115 Chav Kawm 22 yog dab tsi?

Covtom ntej no - tiam ultra- siab - kev ua tau zooEFW yeeb nkab rau huab cua txias:

CJP115++: Advanced chemistry (C Tsawg dua lossis sib npaug 0.22%, Mn 1.20-1.50% + Ni 0.40-0.80% + microalloying)

Chav Kawm 22: 2,200 psi (15.2 MPa) hydrostatic siab(New kev lag luam qab nthab)

Kev tawg: Ua ntej kom ua tiav-175 ° F (-115 ° C) kev pabcuam kubntawm chav kawm siab no

2. Kev nce qib tseem ceeb ntawm kev siv tshuab?

Ua kom muaj zog:

Tawm tswv yim: Ntau dua lossis sib npaug rau 40 ksi (275 MPa)

Tensile: 70-95 ksi (485-655 MPa)

Unmatched toughness:

Charpy V-ntsis:Min 30 ft-lb (41 J) ntawm -175℃F

Accelerated txias + temperingKev kho cua sov

Corrosion kuj: Ntxiv Cr 0.30-0.60% rau qaub kev pab cuam compatibility

3. Txiav - daim ntawv thov ntug?

Tom ntej no -gen LNG mega - tsheb ciav hlau(10+ MTPA muaj peev xwm)

Polar subsea gas pipelinesnrog HP / HT cov cai

Ua kua hydrogen / helium thaujrau qhov chaw infrastructure

Quantum suav suav cryogenic faib tshuab

4. Kev tsim kho tshiab?

Vuam:

AI-zoo laser-arc hybrid EFWnrog lub sijhawm tiag tiag - kuaj pom qhov tsis raug

100% automated phased-array UT + DR tshuaj xyuas

Khoom siv:

Ultra{0}} hlau huv(S Tsawg dua lossis sib npaug rau 0.005%, P Tsawg dua lossis sib npaug rau 0.010%)

ASTM A841 TMCP phaj nrog nano- nag lossis daus khov

Kev sim:

Cryo-Kev kuaj qaug zog(-175℃F txog +150℃F caij tsheb kauj vab)

Advanced CTOD/ECA validationRaws li BS 7910: 2025

5. Kev sib tw zoo?
