Kev tsim hluav taws xob thiab kev tsim boiler
Kev kub siab lub nkoj thiab cia tank fabrication
Cov cuab yeej siv xws li:
Reactors thiab separators
Kub exchangers
Spherical tanks thiab roj & roj cia tank
Boilers thiab lwm yam siab - khaws cov khoom
Cov yam ntxwv ua haujlwm
SA612 steel phaj muaj:
Lub zog tensile siab thiab lub zog tawm los rau siab - kev pabcuam kabmob
Zoo elongation thiab notch toughness, haum rau qis -kub ua haujlwm
Cov khoom siv ruaj khov tom qab normalization
Weldability zoo raws li ASME - cov txheej txheem vuam tsim nyog
Microalloyed muaj pes tsawg leeg (xws li tswj Nb, V, Ti) rau grain refinement thiab toughness
Cov khoom no ua rau SA612 haum rau ntev -lub sijhawm, kev nyab xeeb- cov cuab yeej siv siab.
Cov ntsiab lus ntawm SA602 Steel Phaj
Daim ntawv thov teb
SA602 tsis yog qib steel lossis cov khoom siv. Hauv feem ntau cov ntsiab lus, SA602 yog hais txog cov khoom siv hluav taws xob, xws li SA602A, qis -faiv fab VHF monolithic ob- sib npaug sib tov uas nquag siv hauv:
RF thiab kev sib txuas lus systems
Tsawg- lub xov tooj cua txais xov tooj cua
Roj teeb - cov khoom siv hluav taws xob siv hluav taws xob
Cov yam ntxwv ua haujlwm
Noj SA602A ua piv txwv, nws cov yam ntxwv tseem ceeb suav nrog:
Kev siv hluav taws xob tsawg heev
Cov suab nrov zoo heev
Muaj peev xwm ua haujlwm siab
Zoo nce, rhiab heev, thiab teeb liab stability
Cov yam ntxwv no tsis muaj feem cuam tshuam nrog cov txheej txheem lossis siab -cov ntawv thov.

SA612 thiab SA602 yog qhov sib txawv thiab yuav tsum tsis txhob muab piv rau cov khoom sib npaug.
SA612 yog lub siab lub nkoj steel phaj tsim los rau cov neeg kho tshuab lub zog thiab kev nyab xeeb nyob rau hauv siab, thaum SA602 yog hais txog cov khoom siv hluav taws xob siv hauv kev teeb tsa thiab kev sib txuas lus.
Thaum xaiv cov khoom siv lossis cov khoom siv, nws yog ib qho tseem ceeb uas yuav tsum tau txheeb xyuas tus qauv thiab daim ntawv thov kom tsis txhob muaj kev ua yuam kev thiab kev yuav khoom.
1. Dab tsi yog SA612 steel phaj?
SA612 steel phaj yog ib tug tua carbon-manganese-silicon (C-Mn-Si) siab hlab ntsha hlau ua raws li ASME SA612 / SA612M thiab ASTM A612 / A612M cov qauv.
Nws yog tsim rau welded siab hlab ntsha ua hauj lwm nyob rau hauv nruab nrab thiab qis kub, yuav tsum tau muaj zog thiab txhim khu kev qha toughness.
2. Dab tsi yog qhov kev thov kub ntawm SA612?
SA612 steel phaj yog haum rau nruab nrab thiab qis - qhov kev pab cuam kub, thiab kev ntsuam xyuas feem ntau ua ntawm -40℃.
Qhov no ua rau SA612 tsim nyog rau cov hlab ntsha siab raug:
Lub caij ntuj sov kub
Pib- nce thiab kaw qhov cua sov caij tsheb kauj vab
Nruab nrab-siab, tsis yog{1}}cryogenic ib puag ncig
3. Dab tsi yog qhov tuab ntawm SA612 steel phaj?
Raws li ASTM A612 / A612M thiab ASME SA612 / SA612M:
Txheem siab tshaj plaws thickness: tsawg dua los yog sib npaug li 25 hli (1 nti)
Hauv kev tsim khoom, SA612 daim hlau tuaj yeem muab rau hauv:
