Cov Txheej Txheem Tsim Khoom Tsis Txaus: Txiaj Ntsig Los Ntawm Txoj Kev Vuam Vuam
Taw qhia: Txuas cov txheej txheem sib txuas rau cov kev pheej hmoo ntawm hluav taws xob welded steel kav
RauCov Hluav Taws Xob Hluav Taws Xob Welded Hlau Kav- Cov khoom lag luam tseem ceeb ntawm Huaneang Steel Yeeb Nkab txiav txim siab cov yeeb nkab cov qauv kev ncaj ncees thiab kev ua kom muaj kev ncaj ncees. Txawm tias muaj cov txheej txheem me me me sib txawv tuaj yeem qhia qhov tsis xws luag uas ua rau siv cov dej qab los tom ntej. Txhawm rau kom nkag siab cov kev pheej hmoo no, peb thawj zaug qhia meej cov ntsiab lus cov khoom:dab tsi yog erw yeeb nkab? Nws yog ib qhohluav taws xob tiv thaiv welded steel yeeb nkabTsim los ntawm fusing steel phaj muaj los ntawm kev tiv thaiv tshav kub, nrog kev siv hluav taws xob ntev uas yog ob qho tib si muaj peev xwm taw tes.ERW cov yeeb nkab ntsiab lusHais txog nws txoj kev ua tau zoo, tab sis qhov kev ua tau zoo no ntawm cov txheej txheem tswj nruj kom tsis txhob muaj qhov tsis xws luag. NrogCov Hluav Taws Xob Hluav Taws Xob Welded Hlau Kav, HFW Steel Kav(High {- zaus welded kav, qhov twgHFW lub ntsiab lusHais txog kev siab siab - zaus siv vuam tam sim no) muaj cov txheej txheem ntau dua - siab} cov xwm txheej siab. Kab lus no yuav siv cov kev pheej hmoo ntawm kev sib sau ua ke, thiab tshaj tawm Welding, nrog Huayang cov ntaub ntawv tsim tawm thiab kev tswj hwm zoo li cov ntaub ntawv ua haujlwm.
Txoj Kev Ua Haujlwm Txheej Txheem Ua Haujlwm: Thawj qhov kev pheej hmoo ntawm kev pheej hmoo
Cov txheej txheem tsim duab sib dhos hlau daim hlau rau hauv cylindrical yeeb nkab tsis muaj cov ntsiab lus uas tsis muaj zog thaum siv, tshwj xeeb tshaj yog rauHlobthiabHFW Steel Kavnrog cov longitudinal wels.
Ntug ob qho tsis xws luag: undermining weld fusion
Ntug dej misalignment thiab seam gaps
RauCov Hluav Taws Xob Hluav Taws Xob Welded Hlau Kav, prefe ntug kev sib txawv yog lub hauv paus rau tag nrho Weld fusion. Huayang cov ntaub ntawv ntau lawm qhia tau tias ntug kev ua tsis zoo tshaj 0.5mm lossis cov leeg cov kis loj dua 0.2mm ncaj qha rau weld tsis xws luag:
Ntug misalignment: Xyoo 2023, ib qho kev hloov kho ib ntus hauv kev tsim cov qaws ntawm Huayang lub dog digHlobYeeb nkab kab tau ua rau 3% ntawm φ114 × 4.5mm kav ntev kom muaj 0.8 hli ntug misalignment. Cov kev sim tom ntej pom tias cov kav dej no tsis xwm yeem weld nkag mus thaum muaj kev cuam tshuam weld los ntawm kev hloov pauv (2.4MPA rau qhov zoo tib yamHlobKav dej).
Ntau dhau ntawm SEAM VAPS: RauHFW Steel Kav, SEAM Qhov kev tshaj 0.1mm pub cua kom nyob hauv Weld, ua porosity. Huaayang lubHFW Steel Yeeb NkabCov kab ntau lawm siv cov txheej txheem ua yeeb yam los saib xyuas cov khoob ntawm φ325} Ib kab ntawm 0.12 hli
Huaayang lub ntug kev ntsuas kev ntsuas
Los daws cov teeb meem no, Huayang tau txais ntaul safe-safeards:
Ua ntej - kev sib sau calibration: Txhua lub zog pib nrog kev sim ua kev sim siv cov phiaj txheem hlau los ntsuas cov qauv yob, kom ua tau zoo dua lossis sib npaug rau 0.3mm.
Tiag - kev soj ntsuam lub sijhawm: RauHFW Steel Kav, txoj kev hloov kho laser kev hloov pauv ntug ntug kev lem ntug, ua rau lub tswb ceeb toom yog tias kev sib txawv ntawm 0.05 hli. Qhov kev ntsuas no txo ntug kev sib txawv -} tej yam tsis xws luag los ntawm 98%.
Dagensional cuam tshuam: ua rau muaj kev ntxhov siab tsis sib xws thiab txi
Ovality thiab phab ntsa thickness unreVenness
Ovality (sib txawv los ntawm lub voj voog zoo nkauj) thiab tsis sib xws phab ntsa thickness ua rau muaj kev ntxhov siab kev ntxhov siab, coj mus rau sab hauv siab:
Ovality tsis xws luag: Dog digHlob pipes with ovality >1% (piv txwv li, φ219mm kav nrog qhov siab tshaj plaws ntawm 221 hli thiab tsawg kawg ntawm 217 hli) tau faib cov siab tsis sib xws. Hauv 2024, ib pob ntawmHlobCov kav dej nrog 1.2% ovality los ntawm lub chaw tsim khoom me me los ntawm cov flattening sab thaum siv nyob rau hauv ib qho kev tswj hwm dej tsawg dua lossis sib npaug rau 1.1 hli), zam qhov kev pheej hmoo no.
Phab Ntsa Thickness UnreVenness: RauHFW Steel Kav, wall thickness deviation >± 0.05 hli tsim cov nyias -}} cov cheeb tsam phab ntsa uas muaj lub siab qis {2 2}} cov kabmob muaj peev xwm. Huaayang siv ultrasonic tuab gauges rau scan tag nrho cov yeeb nkab ntev {}} kev tshuaj xyuas, 0.5% ntawm φ273 × 8mm HFW Steel Kav Tau tsis lees txais vim 0.08mm Thickness sib txawv, raws li sim raws li cov kav dej no yuav xau ntawm 80% ntawm qhov ntsuas siab (8MPA).
Kev tswjfensional hauv Huayang lub ntau lawm
Huayang Ua kom zoo rau kev ua kom tsis txhob muaj qhov cuam tshuam txog kev sib txawv ntawm qhov txawv txav:
Multi - roll gradient txoj kev sib haum: 4-6 teev cov yob ntawm kab rov tav thiab 3-4 txheej ntawm ntsug yob maj mam puab cov hlau phaj, txo qhov zes tawm los ntawm tsis sib xws.
Thickness Vaj Tseb Kho: Rau HFW Steel Kav, Cov tuab xov thij Thome xa tiag tiag - lub sij hawm cov ntaub ntawv rau cov qauv yob tswj system, cia li hloov kho tuab li ntawm ± 0.05mm.
Vuam Txheej Txheem Defagicencies: Lub Txheej Txheem Ua Ntej Ntawm Hluav Taws Xob Hluav Taws Xob Welded Hlau Kav
Txoj kev vuam vuam yog qhov tseem ceeb tshaj plaws txuas rauCov Hluav Taws Xob Hluav Taws Xob Welded Hlau Kav{{0-} defagicencies ntawm no ncaj qha tsim cov kab khiav. Rau ob qho tib si dog digHlobthiab siab -} Kev ua HFW Steel Kav, Weld tsis xws luag yog qhov ua rau muaj xau.
