1. ASTM A671 CJP115 Chav Kawm 10 yog dab tsi?
Ib qho specification rauhluav taws xob-fusion-welded (EFW) steel kavtsim rauqis- kub thiab siab - kev pabcuam siab.
CJP 115: Qhia txog chemistry (carbon steel) thiab kev ntsuam xyuas cuam tshuam ntawm-115 ° F (-82 ° C).
Chav Kawm 10: Hydrostatic xeem siab ntawm1,000 psi (6.9 MPa).
2. Cov khoom tseem ceeb?
Qib: Sib piv rau API 5L Qib B, tab sis ua kom zoo rau cov xwm txheej cryogenic.
Lub zogKev tawm tswv yim ntau dua lossis sib npaug ntawm 35 ksi (240 MPa), Tensile: 60–85 ksi (415–585 MPa).
Impact Test: Charpy V-ntiv tes yuav tsum tau ntawm-115℃Flos xyuas kom meej brittle puas kuj.
Kev kho cua sov: Normalized rau txhim kho toughness.
3. Cov ntawv thov zoo li cas?
Siv hauv:
LNG cov kav dejthiab cia systems.
Arctic roj / rojinfrastructure.
Cryogenic txheej txheem piping(piv txwv li, ethylene, ammonia).
4. Kev tsim khoom xav tau?
Vuam: Ob npaug -welded seams nrog100% radiographykev tshuaj xyuas.
Chemistry: Tsawg sulfur / phosphorus (max 0.025% txhua) txhawm rau tiv thaiv kev tawg.
Kev sim: Hydrostatic + kev ntsuam xyuas cuam tshuam ntxiv.
5. Nws txawv li cas ntawm Chav Kawm 12?
Chav Kawm 10muaj qis hydrostatic siab (1,000 psi vs. Class 12's 1,200 psi).
Ob leeg sib koom ib yamCJP 115chemistry / cuam tshuam cov cai.
