Daim ntawv thov
Roj & Roj Kev Lag Luam
Qhov zoo tshaj plaws rau kev tsim cov txheej txheem tseem ceeb xws li cov reactors, cov hlab ntsha siab, cov khoom siv hluav taws xob, thiab cov khoom sib cais siv hauv cov roj refining, roj ua, thiab cov dej ntws tawm. Nws xa cov kev ua tau zoo tiv thaiv qhov kub thiab txias, hloov pauv hloov pauv, thiab cov roj qaub corrosion, ua kom lub sijhawm ntev - kev nyab xeeb kev ua haujlwm hauv thaj chaw hnyav thiab qhov chaw ua kom zoo.
Kev ua tshuaj lom neeg
Ib qho khoom siv zoo tshaj plaws rau kev tsim khoom siv ua haujlwm nrog kev tuav cov tshuaj hnyav thiab corrosive, xws li tshuaj reactors, kaw cia tank, thiab hloov chaw. Nws muaj zog corrosion kuj thiab cov qauv kev ruaj ntseg tiv thaiv cov khoom degradation, txawm tias thaum raug acidic, alkaline, lossis oxidizing media nyob rau hauv kev ua haujlwm tas li.
Lub zog tiam
Dav siv nyob rau hauv thermal fais fab chaw nres tsheb rau qhov tseem ceeb heev - qhov kub thiab txias Cheebtsam xws li industrial boilers, tshav kub rov qab chav generators (HRSG), chav turbine casings, thiab chav headers. Nws tiv taus huab cua kub caij tsheb kauj vab thiab siab - qhov chaw siab ntawm chav dej, tswj kev nkag tau zoo heev thiab lub zog txhua yam los txhawb kev tsim hluav taws xob tsis cuam tshuam.
Petrochemical cog
Tshwj xeeb tsim nyog rau kev tsim cov khoom hnyav- lub nkoj siab siab thiab siab - cov txheej txheem cov kav dej kub tau koom nrog hauv kev tsim cov khoom siv petrochemical feedstocks, polymers, thiab cov tshuaj tshwj xeeb. Nws ua tau zoo nyob rau hauv kev tiv thaiv kev sib koom ua ke ntawm kev kub siab, kev kub siab, thiab corrosive hydrocarbon sib tov ib yam ntawm cov txheej txheem petrochemical.
General Industrial
Siv nyob rau hauv fabrication ntawm high-kub industrial ducting, hnyav- lub luag hauj lwm yeeb nkab clamps, thiab load- bearing structural Cheebtsam deployed nyob rau hauv xav tau kev khiav hauj lwm tej yam kev mob (xws li, metallurgical smelting, cement ntau lawm, thiab pov tseg incineration). Nws zoo formability thiab weldability kuj ua rau nws muaj ntau yam kev xaiv rau kev cai muaj khoom siv uas yuav tsum tau ua kom sov thiab corrosion kuj.
Yog tias koj muaj qhov yuav tsum tau ua rau SA 387 Qib 22 Chav Kawm 2, peb zoo siab tos txais koj qhov kev nug. GNEE tuav cov khoom lag luam loj uas feem ntau siv cov qib siab zog steel rau koj xaiv.Rau cov ncauj lus kom ntxaws txhua yam khoom, tshuaj lom neeg muaj pes tsawg leeg, thiab cov ntaub ntawv kev, nrog rau cov qauv dawb, thov hu rau peb lub Hoobkas tam sim ntawd. Peb muab cov nqi sib tw, ruaj khov zoo, thiab kev pabcuam tshaj lij. Email: beam@gneesteelgroup.com.
1.Dab tsi yog SA 387 Qib 22 Chav Kawm 2 sib npaug?
SA 387 Qib 22 Chav Kawm 2 yog chromium-molybdenum alloy steel rau siab-kub siab cov hlab ntsha, nrog cov sib npaug thoob ntiaj teb tseem ceeb yog EN/DIN 10CrMo9-10, BS 622-515B, thiab JIS SCMV4, txhua yam muab cov roj zoo sib xws, kev siv tshuaj lom neeg thiab kev tiv thaiv corrosion.
2. Puas yog SA 387 Qib 22 Chav Kawm 2 sib npaug rau SA 387 Qib 22 Chav Kawm 1?
Tsis yog, SA 387 Qib 22 Chav Kawm 2 tsis sib npaug rau Chav Kawm 1; lawv sib koom tib yam tshuaj muaj pes tsawg leeg tab sis muaj cov khoom sib txawv, nrog rau Chav Kawm 2 muaj zog tensile thiab tawm los ntau zog (515-690 MPa tensile, 310 MPa tawm los) piv rau Chav Kawm 1 (415-585 MPa tensile, 205 MPa tawm los). Ob chav kawm muaj tib qhov elongation (18% hauv 50mm) thiab txo qhov cheeb tsam (45%), tab sis Chav Kawm 2 muaj lub zog zoo tshaj plaws rau kev thov cov ntawv thov kub.
