LSAW EN10219 Carbon Steel Yeeb Nkab Desulfurization Pipeline DN850

Hebei Huayang Steel Pipe Co., Ltd yog ib qho ntawm cov ua lag luam thiab cov neeg muag khoom ntawm lsaw en10219 carbon steel yeeb nkab desulfurization pipeline dn850 hauv Suav teb. Thov koj xav tias dawb mus yuav pheej yig lsaw en10219 carbon steel yeeb nkab desulfurization pipeline dn850 los ntawm peb lub hoobkas. Tag nrho cov khoom customized yog nrog cov khoom zoo thiab tus nqi qis.

DN850 desulfurization pipeline poob raws li EN 10219 system. Rau cov ntawv loj - txoj kab uas hla, LSAW (Longitudinal Submerged Arc Vuam) txheej txheem yog qhov tsim nyog dua. Cov ntaub ntawv hauv paus pib los ntawm cov ntawv pov thawj hauv tsev steel mills, nrog rau cov khoom siv hluav taws xob ntshiab rau cov coils / daim hlau thiab cov khoom sib xyaw ua ke. Kev tsim cov yeeb nkab ua raws cov txheej txheem pov thawj: dabtsi yog khoov / coiling → beveling → ob -sided submerged arc vuam. Lub zog tawm los thiab qis- qhov kub thiab txias cuam tshuam yog tsim los nrog engineering- yuav tsum tau rov ua dua. Huayang kev cog lus rau cov khoom siv raw thiab cov khoom siv vuam zoo tsis yog cov lus hais xwb - nws yog lub hauv paus rau kev xa khoom tiav.

DN850 cov kav dej muaj ib txoj kab nruab nrab ntawm kwv yees li 850mm thiab phab ntsa tuab ntawm 8-18mm-ib qho kev qhia tshwj xeeb rau cov haujlwm desulfurization. Tsau ntev ntawm 6-12m yog qhov tsim nyog rau kev thauj mus los thiab kev tsim kho segmentation. Cov kav dej no feem ntau yog siv hauv flue gas desulfurization systems ntawm thermal fais fab nroj tsuag, coking nroj tsuag, thiab petrochemical chaw rau slurry ncig thiab limestone / gypsum ntub desulfurization thauj seem. Qhov zoo ntawm txoj kab uas hla loj xws li muaj peev xwm txaus, txo sedimentation, thiab tswj lub twj tso kua mis siab poob, ua rau nws tsim nyog rau kev ua haujlwm tas mus li ntev nrog cov slurry heev. Thaum tsim DN850 cov kav dej, peb muab qhov tseem ceeb ntawm kev sib tw thiab kev ncaj, uas ua kom yooj yim rau kev sib dhos thiab sib dhos yooj yim.

Tsim nyob rau ntawm mature yob dabtsi yog khoov / coiling kab, xyuas kom meej bevel lub kaum sab xis tswj thiab tag nrho, zoo ib yam weld hlaws tsim. Tshaj tawm -weld, 100% ultrasonic kuaj (UT) yog ua tiav ntawm tag nrho cov vuam, nrog UT qhov chaw scanning thiab daim ntawv qhia chaw. Yog tias tsim nyog, ntxiv X-ray re-kev tshuaj xyuas thiab random sampling yog ua rau kev khaws cia. Online kawg expansion thiab straightening kom zoo ib yam roundness thiab straightness - tseem ceeb rau flue gas desulfurization yeeb nkab taub qab vuam. Huayang's nyob rau hauv- lub tsev kuaj xyuas lub tsev khaws cov ntaub ntawv tus kheej rau txhua lub yeeb nkab: daim ntawv qhia qhov chaw vuam, cov ntawv ceeb toom kev sim, thiab tshuaj lom neeg muaj pes tsawg leeg. Cov ntaub ntawv tiag tiag precedes cov yeeb nkab nws tus kheej.

Desulfurization slurry tej yam kev mob yog hnyav; tsis saib xyuas kev tiv thaiv caw cov twj tso kua mis tsis ua haujlwm. Peb muab kev tiv thaiv corrosion tseem ceeb xws li 3PE, 2PE, thiab FBE rau ib txoj haujlwm yuav tsum tau ua, ntxiv rau kev ua haujlwm sib sib zog nqus- kev sib sib zog nqus ua haujlwm xws li kev hnav sab hauv-cov ntaub ntawv tiv thaiv, flange ua ntej- vuam, thiab vuam ntawm nqa lub log positioning daim hlau. Ua ntej xa khoom, peb ua 1.5 zaug tsim kev ntsuas siab hydrostatic nrog kev ruaj khov siab, tsim cov ntaub ntawv qhia ntxaws ntxaws. Peb lub Hoobkas nyob hauv Mengcun, thiab peb zoo siab tos txais tuaj ntsib txhua lub sijhawm los kuaj xyuas cov seams thiab cov neeg ua pov thawj. Cov ntaub ntawv cov ntaub ntawv, cov ntawv ceeb toom nkhaus, thiab cov ntawv ntim tau muab ua tiav, ua tau raws li qhov ntev - lub sijhawm ua haujlwm ruaj khov ntawm cov kav dej desulfurization.
