Ntau tus neeg muas zaub nug tib lo lus nug thaum xaiv cov hlau rau boilers thiab cov hlab ntsha siab: Dab tsi qib ntawm cov hlau puas boiler phaj tiag tiag?
Hauv kev muaj tiag, "boiler steel phaj" tsis yog lub ntsiab lus dav dav tab sis hais txog cov phaj tshwj xeeb uas tsim los rau siab- cov khoom siv bearing, poob rau hauv cov hlab ntsha siab steel qib qeb. Hom steel phaj no yuav tsum ua kom tau raws li qhov yuav tsum tau ua kom muaj zog, toughness, weldability, thiab tsis kam mus rau qhov kub thiab txias. Ntawm ntau cov qib boiler steel phaj,A516 Gr . 70stands raws li cov feem ntau lug siv thiab tsis tu ncua txhim khu kev qha thawj cov ntaub ntawv, ua hauj lwm raws li peb lub tuam txhab cov khoom tseem ceeb. Yog hais tias koj xav tau no steel phaj, thov koj xav tias dawb rautiv tauj peb txhua lub sijhawm.
I. Dab tsi ntawm cov hlau yog A516 Gr.70?
A516 Gr.70 yog cov pa roj carbon steel phaj rau nruab nrab - thiab qis -kub siab cov hlab ntsha raws li American ASME / ASTM cov qauv. Nws yog ib qho tshwj xeeb 70-qib lub zog steel rau boilers thiab cov hlab ntsha siab.
Nws qhov sib txawv tseem ceeb ntawm cov phiaj hlau zoo tib yam yog nyob rau hauv nws qhov tshwj xeeb tsim rau boilers thiab cov hlab ntsha siab. Nws muaj ntau dua purity, superior cuam tshuam toughness, thiab ruaj khov weldability, kom ntseeg tau ntev -lub sij hawm ua hauj lwm zoo nyob rau hauv lub siab thiab kub tej yam kev mob.
Qauv:ASTM A516 / ASME SA516
Khoom siv:Siab- zoo carbon structural steel (carbon-manganese steel)
Qib Qib:Gr.70 (Tensile Zog Ntau dua lossis sib npaug rau 485MPa)
Daim ntawv thov:Nruab nrab-tsis kub, siab-cov kabmob, cov qauv welded
II. Vim li cas A516 Gr. 70 haum rau Boiler Steel Phaj?
Raws li cov khoom siv dav dav rau boilers thiab cov hlab ntsha siab, A516 Gr. 70 muaj qhov zoo sib xws:
Lub zog nruab nrab rau kev ntseeg siab siab ua haujlwm
Nrog lub zog tensile ntawm 485-620 MPa, A516 Gr. 70 steel daim hlau ua tau raws li qhov yuav tsum tau muaj siab rau feem ntau nruab nrab- thiab qis-siab boilers, chav nruas, thiab cua sov exchangers.
01
Zoo heev Low-Tsub Toughness, Resistant rau Brittle Fracture
Nws tuav tau zoo toughness ntawm -46 degree, ua rau nws haum rau qis kub cia tank thiab boiler auxiliary khoom.
02
Superior Weldability
Lub A516 Gr. 70 steel daim hlau muab los ntawm peb lub tuam txhab tau txais kev tswj hwm cov ntsiab lus ntawm carbon. Lawv ua kom muaj kev ua haujlwm txias thiab kub ua haujlwm zoo thiab weldability, txo qhov kev pheej hmoo tawg thiab txo cov nqi ua haujlwm.
03
Siab -Qhov kub thiab txias
Haum rau qhov nruab nrab -kub boiler tej yam kev mob, nws tswj microstructure ruaj khov thiab muaj kev nyab xeeb siab thaum lub sij hawm ua haujlwm ntev -.
04
Internationally lees paub thiab dav txais
A516 Gr. 70 yog qib thoob ntiaj teb hauv kev lag luam boiler thiab siab hlab ntsha, feem ntau siv rau hauv ob qho tib si xa tawm thiab cov khoom siv txawv teb chaws.
05
III. Nyob rau hauv lub Boilers/Pressure Vessels A516 Gr70 feem ntau siv?
Boiler drums, boiler plhaub, chav generators
Siab Cheebtsam rau nruab nrab- thiab qis-siab boilers, fais fab mov boilers
Thaum tshav kub kub exchangers, reactors, separators
Liquefied petroleum gas (LPG) cia tanks, kheej kheej tanks, tshuaj cia tanks
IV. Cov ntsiab lus
Boiler steel phaj yog tshwj xeeb siab-cov khoom siv rau cov hlab ntsha siab. Ntawm lawv, A516 Gr70 sawv ua qhov sib npaug thiab dav siv Qib 70 carbon steel phaj raws li Asmeskas tus qauv. Nws ua ke lub zog, toughness, weldability, thiab siab -kub tsis kam, ua rau nws yog ib qho tseem ceeb ntawm cov khoom siv boiler thiab siab hlab ntsha.
Peb tshwj xeeb xyoo - puag ncig hauv A516 Gr.70 steel daim hlau, muab cov lus qhia dav dav thiab zoo ib yam uas ua tau raws li cov qauv kev lag luam sib txawv rau boilers thiab cov hlab ntsha siab. Peb muab cov ntaub ntawv pov thawj txhim khu kev qha rau kev ua haujlwm ruaj ntseg thiab txhim khu kev qha.Tiv tauj peb txhua lub sijhawm!
