Applied nyob rau hauv Boiler Systems ntawm Thermal Fais Fab Cog rau Gas Ducts thiab Cua Preheaters
Tsis ntev los no, Gnee ua tiav kev tsim khoom, tshuaj xyuas, thiab xa khoom ntawm 200 tons ntawmSPA-H weathering steel daim hlau, uas tau raug xa tawm mus rau United Arab Emirates.
Cov ntaub ntawv yuav raug siv nyob rau hauv lub thermal fais fab nroj tsuag boiler system, feem ntau yog rau fabrication ntawm Gas Ducts thiab Cua Preheaters, uas yog ib qho tseem ceeb Cheebtsam raug rau siab - kub flue gas ib puag ncig.
Qhov project no sawv cev rau ib qho kev siv cov huab cua steel hauv lub tshuab hluav taws xob boiler, qhov twg cov ntaub ntawv yuav tsum tau ua kom ntseeg tau nyob rau hauv qhov kub thiab txias, corrosive flue gas, thiab ntev - lub sij hawm sab nraum zoov raug.
Qhov zoo ntawm SPA-H Weathering Steel hauv Kev Siv Hluav Taws Xob Boiler
SPA-H yog lub siab -kev ua tau zoo huab cua cov qauv hlau tsim los muab kev tiv thaiv zoo rau atmospheric corrosion. Nyob rau hauv thermal fais fab nroj tsuag, Cheebtsam xws li gas ducts thiab cua preheaters yog tsis tu ncua mus rau:
- High -kub flue gas flow
- Sulfur- muaj cov pa roj thiab hmoov av
- Condensation corrosion tshwm sim los ntawm kub hloov pauv
By alloying elements such as Cu, Cr, and Ni, SPA-H forms a stable and dense protective oxide layer on the steel surface, significantly slowing corrosion compared with ordinary carbon steel. Qhov no ua rau SPA-H tshwj xeeb tshaj yog haum rau boiler system qauv, muab:
- Extended kev pab cuam lub neej
- Txo cov nqi tu thiab kho dua tshiab
- Txhim khu kev ua tau zoo rau cov qauv welded loj ua haujlwm nyob rau lub sijhawm ntev
Cov neeg siv khoom keeb kwm yav dhau thiab cov txheej txheem xaiv cov khoom
Tus neeg siv khoom yog lub chaw tsim khoom hluav taws xob hauv zos thiab cov khoom siv tsim khoom tsim khoom hauv UAE, muab cov khoom siv rau lub tsev tshiab thermal fais fab nroj tsuag.
Thaum thawj zaug kev sib tham, tus neeg siv khoom tau hais meej meej cov kev xav tau hauv qab no:
- Daim ntawv thov:
Boiler system
Gas Ducts thiab Cua Preheaters
- Cov kev pab cuam:
High -kub flue gas
Ntev - raug sab nraum lub sijhawm
- Cov kev txhawj xeeb tseem ceeb:
Corrosion kuj
Weldability thiab fabrication kev ua tau zoo
Cov khoom ruaj khov thiab tswj lub sijhawm xa khoom
Cov neeg siv khoom tau soj ntsuam ntau yam kev xaiv, suav nrog cov pa roj carbon steel, coated steel daim hlau, thiab huab cua hlau. Tom qab Gnee muab kev sib piv, kev txheeb xyuas tus nqi ntawm lub neej, thiab siv cov ntaub ntawv siv, SPA-H raug xaiv los ua cov khoom tsim nyog tshaj plaws rau txoj haujlwm no.
Cov txheej txheem ua pov thawj kev txiav txim
Thaum lub sijhawm lees paub qhov kev txiav txim, ob tog tau tsom mus rau cov ntsiab lus meej thiab siv tau los xyuas kom meej tias kev ua tiav txoj haujlwm zoo:
- Steel qib thiab tus qauv lees paub
SPA-H weathering steel phaj tau teev tseg rau qhov project
- Thickness thiab dimensional verification
Txiav txim siab raws li cov qauv kos duab rau cov kav dej thiab cua preheaters
- Welding thiab fabrication xav txog
Vuam cov lus pom zoo thiab kev tsim khoom tau sib koom
- Kev soj ntsuam thiab cov ntaub ntawv xav tau
Kev soj ntsuam tag nrho thiab Daim Ntawv Pov Thawj Zeb Xeem (MTC) tau pom zoo
Tom qab tag nrho cov lus qhia thiab kev lag luam tau ua tiav, daim ntawv cog lus rau 200 tons ntawm SPA-H steel daim hlau tau lees paub.
Cov txheej txheem tsim khoom nruj thiab tshuaj xyuas
Txhawm rau ua kom tau raws li qhov yuav tsum tau ua ntawm cov khoom siv hluav taws xob boiler, Gnee tau ua raws li kev tswj hwm thiab kev tshuaj xyuas zoo rau cov khoom ntawm SPA no -H steel daim hlau.
Cov khoom tseem ceeb soj ntsuam
| Cov khoom soj ntsuam | Cov ntsiab lus tshuaj xyuas | Lub hom phiaj |
|---|---|---|
| Chemical Composition Analysis | C, Si, Mn, P, S, Cu, Cr, Ni | Xyuas kom ruaj khov huab cua thiab corrosion kuj |
| Tensile Test | Yield zog, tensile zog, elongation | Txheeb xyuas cov qauv load-cov kabmob muaj peev xwm |
| Impact Test | Kev cuam tshuam lub zog ntawm qhov ntsuas kub | Xyuas kom toughness thiab kev nyab xeeb ntawm kev ua haujlwm |
| Dimensional & Visual Inspection | Thickness kam rau ua, flatness, nto zoo | Ua raws li fabrication thiab installation yuav tsum tau |
| Traceability Control | Thaum tshav kub kub tooj thiab batch identification | Ua kom tiav qhov project traceability |
Cov cuab yeej cuab tam zoo ntawm SPA-H (Reference)
| Khoom | Yam yuav tsum tau muaj |
|---|---|
| Yield zog | Ntau dua lossis sib npaug li 355 MPa |
| Tensile zog | 490-630 MPa |
| Elongation | Ntau dua lossis sib npaug li 20% |
| Atmospheric Corrosion Resistance | Qhov tseem ceeb zoo dua li carbon steel |
Txhua qhov kev soj ntsuam tau raug sau tseg, thiab ua tiav Daim Ntawv Pov Thawj Mill Test (MTC) tau muab thiab xa nrog cov khoom xa tuaj kom ntseeg tau tias qhov chaw zoo txais los ntawm cov neeg siv khoom.
Export thiab Delivery Assurance
Tom qab kev pom zoo zaum kawg, cov hlau phaj tau ntim raws li cov qauv xa tawm los tiv thaiv kev puas tsuaj thaum lub sij hawm ntev - kev thauj mus los hauv hiav txwv thiab hnyav Middle Eastern climatic tej yam kev mob.
Cov khoom xa tuaj tau xa tuaj raws li lub sijhawm pom zoo, ua kom muaj kev txhawb nqa raws sijhawm rau cov neeg siv khoom boiler system fabrication.
Qhov project tseem ceeb
Kev xa tawm tau zoo ntawm 200 tons ntawm SPA-H weathering steel daim hlau rau UAE thermal fais fab nroj tsuag ntxiv qhia tau tias Gnee muaj peev xwm muab cov khoom siv txhim khu kev qha rau lub tshuab fais fab boilers thiab flue gas systems.
Gnee tseem cog lus tias yuav muab cov khoom zoo- cov khoom hlau zoo, kev txhawb nqa kev tshaj lij, thiab kev xa khoom ruaj khov rau lub zog thiab kev lag luam thoob ntiaj teb.
