III. Daim Ntawv Thov Kev Pab Cuam
Nrog ob qho tib siSiab Zogthiabsiab corrosion tsis kam, E308T1 {-} 1 stainless hlau-cored vuam hlau yog xav tau qhov xav tau rau cov xwm txheej hauv qab no thiab cov khoom siv hauv qab no:
Cov Ntawv Thov Cov Ntawv Sau Npe:
Petrochemical Kev Lag Luam: Vuam ntawm Kis Pipelines thiab Cov Khoom Siv Hluav Taws Xob
Huv - Cov Khoom Siv Qib: Cov Khoom Noj Khoom Siv Khoom Noj Khoom Noj (Xyuas Huv) Kom Zam Cov Hlau ion Kev paug paug)
High - Cov Khoom Siv Siab: Cov Khoom Siv Siab thiab Cov Khoom Siv Chiv
Tshwj xeeb muaj teb: ib pab pawg ntawm nuclear reactors
Tau Tshaj Cov Khoom Siv Hluav Taws Xob: Stainless hlau cov ntaub ntawv xws li 12cr18ni9 (sus 302) thiab 06cr18ni10 (sus 304)
IV. Phau Ntawv Qhia Kev Lag Luam thiab Kev Ceev Faj
1. Npaj ua ntej vuam
Kom huv si tshem impurities xws liRoj stains, xeb, thiab noo nooLos ntawm qhov chaw vuam thiab zawj nyob saum npoo av, thiab txhuam kom txog thaum cov hlau taub hau tau zoo li cov hws thiab cov kab nrib pleb thaum lub sij hawm vuam.
2. Pom zoo vuam tsis
Kev thaiv cov roj: cov pa dej ntshiab yog pom zoo, nrog tus nqi txaus tswj hwm ntawm20-25l / min
Lo -} tawm ntev: tswj tau ntau yam15-25mmkom ntseeg tau tias arc stability
Tswj tam sim no: dav dav rau tag nrho - Txoj haujlwm vuam tuaj yeem hloov kho raws li xav tau. Ntawm lawv, tam sim no rauNtsug Vuam / Nyiaj Siv Ua Haujlwm Vuam yuav tsum raug txo kom 100-140Akom ntseeg tau tias qhov zoo ntawm weld tsim
3. Tseem ceeb ceeb toom
Cov vuam txoj kev vuam, tej yam kev mob, thiab cov lus qhia tshwj xeeb hauv cov khoom piav qhia yog rau kev siv xwb. Ua ntej vuam vuam,Cov txheej txheem tsim nyogYuav tsum ua kom tiav raws li cov yam ntxwv ntawm cov cuab yeej thiab cov kev cai ua haujlwm kom ntseeg tau cov txheej txheem kev sib txuam thiab kev nyab xeeb.
V. Cov Lus Nquag Nug (FAQ)
Q: Puas yog qhov vuam hlau tsim rau high - qhov chaw ib puag ncig?
A: Nws tuaj yeem tiv taus kub ntawm 400℃rau lub sijhawm luv luv; Rau ntev - kev ua haujlwm hauv high- tej yam kev mob siab, nws raug nquahu kom siv vuam hlau nrog siab dua npib (xws li E310T1-1).
Q: Nws puas tuaj yeem hloov er308 cov khoom - tseem ceeb rau cov hlau?
A: Yog. Flux -} cored vuam hlau muaj cov txheej txheem zoo dua, thiab nws yog qhov zoo tshaj plaws, tshwj xeeb} txoj hauj lwm vuam lossis phau ntawv welding scarsios.
Q: Puas yog nws txhawb nqa txhua - txoj hauj lwm vuam?
A: Nws txhawb nqa ncaj vuam, ntsug vuam, kab rov tav vuam, thiab siv thoob plaws vuam; Nco ntsoov tias qhov tam sim no yuav tsum tau tswj hwm ntawm 100-140A thaum lub sijhawm vuam vuam / overhead vuam.
VI. Hom thiab Cov Ntaub Ntawv Kev Lag Luam
Hom Zog: Txij li thaum 1995, Dej hiav txwv vuam tau ua rau muaj kev koom tes hauv lub vuam cov ntaub teb. Nws yog lub tuam txhab Vuam Vuam Vuam Phop thiab cov khoom lag luam hauv Suav teb, muaj peev xwm ruaj khov thiab kev txhawb nqa kev ua haujlwm.
Kev Tso Tawm Zoo: Kev hloov pauv cov txheej txheem xws li kev lag luam wholesale thiab cov nyiaj cheb tau muab kom tau raws li qhov xav tau ntawm ob qho ntawm "siab tus nqi- ua hauj lwm zoo + zoo". Txais tos rau nug thiab yuav khoom.
