Daim Ntawv Thov Zaj Dab Tsi Thiab Qhov Tseem Ceeb Ntawm Nyias - walled stainless hlau luj
Nyias -} walled walled stainless hlau luj yog tus cwjpwm yog tus cwj pwm los ntawm corrosion tsis kam, siab lub zog thiab kev nyiam huv. Lawv tau dav siv nyob rau hauv cov zaub mov siv tau kua hauv tshuaj, khoom noj thiab khoom lag luam. Hauv kev lag luam tshuaj, lawv muaj lub luag haujlwm rau kev hloov chaw ntawm cov neeg sawv cev hauv cov neeg sawv cev; hauv kev lag luam khoom noj khoom haus, lawv tsis - polluting cov yam ntxwv kom muaj kev nyab xeeb; thiab hauv kev lag luam hauv tsev tshuaj, lawv cov ruaj khov kom ua kom ib puag ncig huv ntau lawm. Txawm li cas los xij, deformation tsim tawm thaum lub vuam ncaj qha cuam tshuam rau kev sib khi ua tau zoo, hydrodynamics thiab tej zaum tseem yuav ua rau cov khoom txi lossis tsis ua tiav. Yog li ntawd, tswj cov vuam deformation yog qhov tseem ceeb heev.
Cov teeb meem tseem ceeb ntawm vuam deformation
Cov yam ntxwv tseem ceeb ntawm vuam deformation yog Angular deformation (tsis txawv txav ntawm cov hlau nplaum (Uneven cua sov ntawm cov qauv sib pauv) thiab tergen kev tawm tsam (helical. Lub hauv paus ua rau nyob hauv cov tswv yim cua sov hauv zos thaum lub sij hawm vuam, uas ua rau cov khoom kom nthuav dav thiab cog lus tsis sib xws tom qab txias. Lub deformation qhov deformation tau agormation los ntawm kev txwv tsis txaus los yog qhov sib txawv ntawm cov khoom thermal conductivity ntawm cov khoom.
Ua ntej - vuam ceev ceev
Lub Zog Vuam Qauv Tsim
Kev ua kom tau zoo khoov geometry, xws li hloov cov ces kaum ntse nrog kev hloov pauv shves, tuaj yeem txo kev ntxhov siab. Ntxiv cov qauv siv hluav taws xob nruj, xws li kev txhawb nqa lossis lub nplhaib txhawb nqa tom qab ntawm khoov, tuaj yeem txhim kho qhov kev tsim tawm ntawm tus qauv tiv thaiv. Lub tuam txhab tshuaj tshuaj muaj ntxiv - kev txhawb nqa cov txuj ci sab hauv ntawm lub luj tshib, txo cov vuam deformation los ntawm 40%.
Meej cov khoom xaiv thiab txiav
Corrosion ntawm cov khoom tuaj yeem zam los ntawm kev siv soldering cov ntaub ntawv uas nws muaj pes tsawg leeg ua ke ntawm cov xoos (piv txwv li 304l steel hlau vuam hlau rau 304 stainless hlau lauj tshiav). Laser -} txiav lossis dej {6} {} ±} Cov khoom siv txuas ntxiv mus vim tias kev tshem tawm cov khoom.
Customized Daim Ntawv Thov Kev Tooling thiab Fixtures
Thaum tsim tshwj xeeb fixtures, kho txoj hauj lwm cov blocks tuaj yeem yoog tau rau cov taub hau sib txawv, thaum nqus tau yooj yim yog tsim nyog rau kho cov chaw. Ib qho khoom noj khoom noj khoom haus cov khoom noj, piv txwv, siv hom kev sib tw ua kom zoo rau 98% los ntawm kev kho cov hlau nplaum kom ua tiav lub luj tshib zoo.
Ua kom zoo ntawm vuam txheej txheem tsis
Tswjhwm kub
Pulsed Mig vuam Hloov Hloov Hloov Hloov Hloov Hloov Hloov Hloov Los Ntawm Mem Tes Tam Sim No, Txo Tshav Kub Kub los ntawm ntau dua 30%. Hauv kev sib piv, tig vuam muaj lub thermal cuam tshuam thaj tsam dav ntawm 25 hli thiab 0.5 tus nqi, tab sis cov khoom siv khoom siv siab dua. Hauv kev xyaum, peb yuav tsum xaiv cov kev tsim nyog raws li qhov ua tau ntawm cov khoom.
Fawm kib thiab segmented vuam lub tswv yim
Cov Weld ntev tau muab faib ua 5-8 ntu los ntawm cov kauj ruam symmetric vuam, thiab hloov kev sib txawv ntawm cov tshav kub sib txawv. Rau Fawm kib vuam, thawj txheej yog ib txwm muaj siv 0.8 hli hlau, txheej tom qab tsim kom tsis pub dhau 1.2 mm, thiab ib qho txheej txheej kub ib zaug yog txo los ntawm 50%. Hauv kev kho mob pipeline project, zaus ntawm yoj deformation yog txo los ntawm 25% mus rau 3%.
Kev Npaj Vuam Seal
Vuam los ntawm nruab nrab mus rau qhov xaus ntawm qhov kawg ntawm kev khoov faib cov kev ntxhov siab rau ob sab. Rau kev sib tsoo welds, lub sij hawm luv vuam txoj kev (20 hli spacer ib 50 hli ntu) ua rau muaj kev cuam tshuam rau kev rhuav tshem. Simulation kev sim qhia tias qhov sib txawv no tuaj yeem txo qis kev ntxhov siab los ntawm 60%.
Taw qhia tiag - lub sij hawm tswj tau thaum vuam
Daim ntawv thov ntawm txoj kev thim rov qab
Tus nqi tiv thaiv rov qab yuav tsum tau xam los ntawm kev siv tshuab precpressure (xws li kev siv cov khoom siv hydraulic kom zoo dua liniver rov qab tsim software. Nyob rau hauv ib tug petrochemical project, DN200 luj tshib yog prepositioned prepositioned prepositioned ntawm ib qho rov qab kaum ntawm 1.5℃thiab qhov tseeb deformation tom qab vuam tau tswj kom tsis pub dhau 0.3 degree.
Rigid kho thiab hammering hauv vuam
Rigid Fixtures thiab welded lub teeb rauj (hatmering counter tswj ntawm 50-100n) tso 15%-20%. Nws yog ib qho tseem ceeb uas yuav tau tuav rab phom rauj ntawm 10-15 hli thiab zam kev ua haujlwm tsis pub dhau 20 hli ntawm Weld Centerline kom tiv thaiv kev puas tsuaj saum npoo.
Kev Saib Xyuas Kev Saib Xyuas Kev Kho Mob thiab Kev Kho Kho
Infrared thermometers soj ntsuam weld kub nyob rau hauv lub sijhawm tiag tiag. Thaum lub zos kub tshaj 200 degrees Celsius, tswj cov lus qhia tshav kub los ntawm kev kho lub vuam ceev (los ntawm 20 rau kev siv cua txias (los ntawm kev siv cov cua txias (los ntawm kev siv cov cua txias txias). Hauv kev ua haujlwm nuclear fais fab, qhov ntau ntawm ntau qhov kev hloov pauv ntawm ± 50 qib}}℃tom qab siv cov tshuab no.

Ntxhov siab lug thiab cov duab -} txav
Kev Kho Mob ntawm 650℃tuaj yeem txo qis kev ntxhov siab los ntawm 70%- 80% thaum rov kho cov khoom siv tau tawm tsam. Rau cov xovxwm hauv zos, cov xovxwm hydraulic nrog cov pwm tshwj xeeb yog siv rau kev sib sau, thiab lub siab yog tswj hwm ntawm 70% ntawm cov paib lub zog ntawm cov khoom. Nyob rau hauv cov khoom noj-qib dabtsi yog khoov, ellipsis tau raug txo los ntawm 3% kom tsawg dua 0.5 %% los ntawm kev phais.
Tsis - kev sim thev naus laus zis
Kev Nkag Mus Kuaj (PT) tuaj yeem tshawb xyuas cov kab nrib pleb loj dua 0.1mm, ht) tuaj yeem txheeb xyuas porosity thiab fusion tsis xws luag. By comparing pre-welding and post-welding models, three-dimensional scanning technology can quantify the℃of deformation (accuracy up to 0.01mm) and provide data support for quality assessment.
