Liquefied natural gas (LNG), uas nws lub ntsiab tseem ceeb yog methane, yog ib qho zoo, huv si, muaj txiaj ntsig thiab yooj yim "cov roj ntsuab", uas yog suav tias yog lub zog fossil huv tshaj plaws hauv ntiaj teb thiab yog ib lub zog tseem ceeb tshaj plaws ntawm 21st. xyoo pua.
9% npib tsib xee hlau yog ib hom uas tsis tshua muaj carbon quenched thiab tempered steel, muaj 9% npib tsib xee keeb, nrog nws zoo heev weldability, tsis tshua muaj nqi, siab zog thiab zoo heev -196 ° C ultra-low kub toughness thiab lwm yam zoo tau ua lub ntsiab. quab yuam nyob rau hauv kev tsim kho ntawm loj-scale LNG cia tank. Peb tau cog lus los tsim cov khoom siv high-end welding consumables thiab muab kev txhawb nqa vuam consumables thiab vuam kev daws teeb meem rau 9% npib tsib xee steel vuam consumables raws li cov khoom lag luam zoo.
"Hais cov mos lwj" - dab tsi ua rau peb cov khoom siv welding sawv tawm
Raws li ob lub siab ntawm lub ntiaj teb lub zog thiab ib puag ncig teeb meem, LNG kev lag luam hauv tsev thiab txawv teb chaws tseem nce ntxiv. Lub ultra-low kub cia tej yam kev mob ntawm LNG yog ib qho nyuaj heev rau cov khoom siv thiab vuam consumables. Rau lub sijhawm ntev, 9% ntawm cov khoom siv vuam siv rau cov nickel steel tau monopolized los ntawm cov khoom siv vuam txawv teb chaws. Txhawm rau txhawm rau rhuav tshem cov cuab yeej siv txawv teb chaws thiab ua tau raws li cov kev xav tau ntawm LNG kev lag luam hauv zos, peb tau ua tus thawj coj hauv kev ua tiav 9% npib tsib xee steel sib piv cov khoom siv thiab vuam txheej txheem, thiab sawv tawm hauv cov neeg coob coob nrog cov khoom zoo, pab pawg kws tshaj lij. thiab kev pabcuam siab thiab xav tau.
Muaj ntau yam kev txhawb nqa vuam consumables thiab vuam txheej txheem yog tsim
Txhua yam catering rau kev lag luam xav tau
Peb tau tsim thiab tsim kom muaj ntau yam zoo, 9% nickel steel sib piv cov khoom siv thiab cov txheej txheem vuam, suav nrog cov electrodes, submerged arc xov hlau thiab flux ua ke, flux-cored xov hlau rau txoj hauj lwm vuam, thiab argon arc vuam hlau. Cov khoom lag luam no muaj qhov zoo tshaj plaws weldability thiab mechanical zog, thiab CTOD thiab poob qhov ntsuas qhov ntsuas tau zoo heev, cov ntsiab lus ntawm cov khoom tshwj xeeb tau qhia hauv cov lus hauv qab no.
Tag nrho ntau yam ntawm 9% nickel steel welding consumables cov ntsiab lus

| Electrode rods | GEN-CM6 | AWS A5.11/A5.11M ENiCrMo-6 GB/T 13814 TIAB SA 6620 | Txoj hauj lwm tag nrho weldability yog qhov zoo heev, qhov kev tso nyiaj tso tawm yog siab, thiab qhov porosity ntawm cov yeeb yaj kiab tag nrho yog qhov tsawg heev. |
| GEN-CM6 (YH) | AWS A5.11/A5.11M ENiCrMo-6 GB/T 13814 TIAB SA 6620 | Tshwj xeeb rau nyiaj siv ua haujlwm vuam, zoo heev porosity kuj thiab tawg tsis kam ntawm nyiaj siv ua haujlwm vuam | |
| SAW + Flux | GWN-CM4 + GXN-600 | AWS A5.14/A5.14M ENiCrMo-4 GB/T 15620 ib 6276 | Tsim thiab tsim rau lub tiaj thiab kab rov tav vuam, qhov flux efficiency siab thiab qhov zoo yog ruaj khov |
| Flux kab hlau | GFN-CM3 | AWS A5.34/A5.34M ENiCrMo3T1-4 | Weldability zoo heev, zoo tawg kuj thiab zoo heev porosity kuj nyob rau hauv tag nrho cov hauj lwm |
| GTAW wire | GTN-CM3 GTN-CM4 | AWS A5.14/A5.14M ENiCrMo-3 / ENiCrMo-4 GB/T 15620 SIB 6625/SNi6276 | Cov hlau molten muaj fluidity zoo, zoo operability thiab zoo heev weld zoo |
"Ob qho nyuaj thiab mos" - tawv zoo, txaus siab rau kev pab
Peb lub tuam txhab cov khoom siv vuam tau tiv thaiv kev sim ntawm kev ua lag luam nrog cov khoom siv vuam zoo heev, thiab yog thawj zaug tau txais patented vuam consumables technology ntawm 9% npib tsib xee steel hauv Suav teb. Rov qab los ntawm R & D muaj zog, pab neeg ua haujlwm thiab kev pabcuam, peb pab cov neeg siv khoom kom ua tiav qhov zoo tshaj plaws 9% nickel steel tov.
Invention patent thiab siv tswv yim
"Ua kev lag luam, tawg txhua qhov chaw" - ua pov thawj lub zog nrog kev ua tau zoo
Peb tau txhawb nqa lub zos ntawm cov khoom siv vuam siv rau 9% nickel-steel LNG cia tso tsheb hlau luam. Txij li xyoo 2016, Jingqun's 9% nickel steel vuam khoom siv tau zoo siv rau LNG marine tso tsheb hlau luam thiab ua tiav cov txiaj ntsig zoo heev. Tom qab ntawd, nws tau tshwm sim nyob rau hauv ob 50,000 cubic meter bimetallic LNG av tank tej yaam num nyob rau hauv Changchun nyob rau hauv 2021, thiab successive txhawb thiab thov nyob rau hauv lub 200,000 cubic meter loj LNG av tank project.
