HauvPeb Hlis 2025, peb tau txais RFQ los ntawm aUAE-raws li qhov kub exchanger fabricatorpab acheeb tsam cua txias qhov project hauv Dubai industrial cheeb tsam.
Cov neeg siv khoom yog anruab nrab - mus rau - tuam txhab fabrication lojuas tsis tu ncua khoom:
Plhaub & raj kub exchangers
Condenser
Cov khoom siv cua txias
Lawv tej yaam num feem ntau yog xa mus raucov neeg cog lus koom nrog hauv cheeb tsam cua txias thiab dej hiav txwv ncighauv thaj av Gulf.
Qhov project pib li cas
Kev nug tuaj nrog:
A Basic specification daim ntawv
General dimensions ntawm lub raj phaj
Khoom xav tau:ASTM SB 171 C46400 1
Txawm li cas los xij, lubcov ncauj lus kom ntxaws drilling kos duab tseem tsis tau tiav.
Cov ntsiab lus tseem ceeb ntawm kev sib tham
Thaum lub sij hawm email thiab kev sib tham, tus neeg siv khoom tau tsom mus rau:
Seb cov khoom puas haum rausiab salinity seawater
Sab hauv zoo (kom tsis txhob ua tsis tiav thaum lub raj drilling)
Flatness kam rau ua rau CNC drilling tshuab
Lawv tau hais txog qhov teeb meem dhau los:
Thaum lub sijhawm drilling, qee cov ntawv raj tau pomme porosity, ua rau rework thiab qeeb.
Cov Lus Qhia Kawg Kom Paub meej
Tom qab 2 rounds ntawm kev paub tseeb, qhov kev txiav txim tau ua tiav raws li:
Khoom siv: Naval tooj dag C46400 (ASTM SB171)
Loj:
Dav: 1160mm
Ntev: 3070 mm
Thickness: 40 hli
Ntim:28 qab
Qhov hnyav ntau lawm
Kev tsim tawm tag nrho:~ 11.0 Nws
Net shipping nyhav:~ 10.6 hli
Txheej txheem ntau lawm
1. Raw Khoom & Melting
Tswj melting siv induction rauv
Tin (Sn) kho rau~1.0%rau kev ua haujlwm marine
2. Rolling & Kev kho cua sov
Kub dov rau loj - daim hlau loj
Intermediate annealing
Kev ntxhov siab zaum kawg -relief annealing
Cov kauj ruam no yog qhov tseem ceeb vim tias:
👉 Tube phaj xav tauruaj khov sab hauv qauv rau drilling ntau txhiab qhov
3. Kev npaj nto
Ua ntej xa khoom:
Ob tog taumilled (tsis yog raw phaj)
Nto oxide txheej tshem tawm
Ntug trimmed
Qhov no txo:
Tool hnav thaum machining
Deg defects thaum lub sij hawm drilling
Kev Tshuaj Xyuas & Kev Tswj Xyuas Zoo
Sijhawm soj ntsuam
Thaum lub sij hawm tsim khoom (hauv- kev kuaj xyuas)
Ua ntej xa khoom (kev tshuaj ntsuam zaum kawg)
Kev soj ntsuam kom pom tseeb
Tshuaj muaj pes tsawg leeg (Sn ntsiab lus lees paub)
Ultrasonic kuaj rau sab hauv tsis xws luag
Kev ntsuas flatness
Kev tshuaj xyuas qhov muag
Cov txiaj ntsig tau pom
Tsis muaj qhov teeb meem sab hauv pom los ntawm UT
Flatness nyob rau hauv tau fabrication ntau
Deg mob haum rau machining
Tag nrho cov txiaj ntsig tau suav nrog hauv:
EN 10204 3.1 daim ntawv pov thawj
Internal QC qhia
Packing & Shipping
Kev ntim khoom
Ntoo pallets (fumigated)
Txhua phaj sib cais nrog kev tiv thaiv mos
Moisture -pov thawj zaj duab xis wrapping
Kev xa khoom
Chaw thau khoom chaw nres nkoj:Shanghai
Qhov chaw:Jebel Ali Port, UAE
Ntim:2 × 20GP
Sijhawm
Production: ~ 3 lub lis piam
Packing & booking: 1 lub lis piam
Kev hla hiav txwv: ~ 3 lub lis piam
✔ Tag nrho:~6–7 lub lis piam qhov rooj- mus rau -chaw nres nkoj
Tom qab xa khoom
Txog3 lub lis piam tom qab tuaj txog, tus neeg siv khoom hloov kho peb thaum ua raws -up:
Tube drilling ua tiav yam tsis muaj cov cuab yeej txawv txav
Tsis muaj teeb meem leakage qhia tom qab sib dhos
Cov khoom sib xws tau txais thoob plaws txhua daim hlau
Lawv kuj hais tias:
"Piv nrog cov khoom siv yav dhau los, machining stability tau zoo dua."
Vim li cas qhov teeb meem no tseem ceeb
Cov ntaub ntawv no qhia txog aqhov xwm txheej tiag tiag hauv Middle East tej yaam num:
Tsis yog "zoo meej spec txij hnub ib" → drawings evolve
Kev txhawj xeeb tiag tiag:drilling kev ua tau zoo, tsis yog chemistry xwb
Qhov tseem ceeb ntawm kev vam meej:internal zoo + flatness, tsis yog kev ua raws cai xwb
Cov ntsiab lus thov
Tube phaj tau siv rau hauv:
Seawater tshav kub exchangers
Cheeb tsam cua txias tshuab
Industrial cua txias loops
Cov tshuab no xav tau:
Ntev - lub sij hawm corrosion kuj
ruaj khov mechanical kev ua tau zoo
Txhim khu kev machining tus cwj pwm
FAQ
1. Vim li cas cov phaj hlau tsis ua haujlwm thaum lub sijhawm drilling?
Feem ntau yog vim qhov porosity sab hauv lossis cov qauv tsis sib xws los ntawm kev ua haujlwm tsis zoo los yog casting.
2. Puas yog C46400 haum rau seawater txias tshuab?
Yog, nws yog dav siv vim nws cov ntsiab lus tin thiab corrosion kuj.
3. Koj puas muab machined raj phaj lossis cov phaj nyoos?
Peb tuaj yeem muab cov khoom nyoos, milled, lossis tag nrho machined raws li cov duab kos.
4. Koj lub sijhawm xa khoom mus rau UAE yog dab tsi?
Nyob ib ncig ntawm 6-7 lub lis piam suav nrog kev tsim khoom thiab kev thauj khoom hiav txwv.
