L245 Pipeline Steel, Nws Ratio ntawm Kev daws
Eddy tam sim no nrhiav tau ntawm Changsha pipeline tsuas yog siv tau rau cov khoom siv hluav taws xob.Yog tias siv cov khoom siv tsis yog siv, vortex zoo li tus tam sim no tsis tuaj yeem raug ntxias thiab eddy tam sim no tsis tuaj yeem siv los tshawb pom.Eddy kev ntsuam xyuas tam sim no tshwj xeeb tshaj yog haum rau qhov chaw thiab ze ze ntawm qhov chaw kuaj cov khoom siv hluav taws xob.Eddy kev ntsuam xyuas tam sim no tsis tas yuav tsum muaj kev sib txuas.Lub tshuab hluav taws xob zoo siab hauv kev ntsuas tam sim no yog qhov tseem ceeb ntawm electromagnetic yoj nrog nthwv dej thiab cov yam ntxwv, yog li kev sojntsuam (coil) thiab cov khoom ua haujlwm tuaj yeem kis tau yam tsis muaj kev sib txuas, yog li kev tshawb nrhiav tsis sib cuag tuaj yeem nqa tawm.Qhov no yog qhov zoo dua li kev tshawb nrhiav ultrasonic.Vim hais tias lub ultrasonic yoj ntawm lub siab tsis tshua muaj boiler raj yog ib tug neeg kho tshuab nthwv dej, nws tsuas tuaj yeem taug kev los ntawm cov khoom siv.Yog li ntawd, kev kuaj xyuas ultrasonic yuav tsum tau ua ke ntawm kev sojntsuam thiab cov khoom ua haujlwm.Eddy kev sim tam sim no tuaj yeem ua tiav kev sim sai thiab tsis siv neeg.Eddy kev ntsuam xyuas tam sim no tuaj yeem tsim nyog rau kev kuaj xyuas cov hlau kub kub vim tias lawv cov hluav taws xob conductivity ntawm qhov kub thiab txias.Changsha pipeline flow detection kuj tsim nyog rau kev tshawb nrhiav cov ntaub ntawv tshwj xeeb zoo li tus, tsuav yog lub kauj yog ua rau ntau yam duab.Feem ntau siv rau cov khoom siv yeeb nkab muaj brinell, rockwell, Vickers hardness 3 yam.Changsha pipeline "Seamless steel yeeb nkab rau Tsawg thiab nruab nrab siab Boiler".Muaj 43 hom changsha pipeline specifications rau txhua yam ntawm boiler lug, nrog diameters ntawm 10 ~ 426mm.Muaj 29 hom phab ntsa thickness ntawm 1.5 hli mus rau 26 hli.Txawm li cas los xij, sab nraud thiab phab ntsa thickness ntawm superheated chav yeeb nkab, cov pa luam yeeb loj, cov pa luam yeeb me me thiab cov kab cib cib siv nyob rau hauv locomotive boiler yog txwv tsis pub.Sab nraud txoj kab uas hla ntawm changsha pipeline yog 22 ~ 530mm, thiab phab ntsa thickness yog 20 ~ 70mm.Cold drawn (txias dov) raj txoj kab uas hla 10 ~ 108mm, phab ntsa thickness 2.0 ~ 13.0mm.Cov tsos mob zoo: tawg, folding, dov, caws pliav, sib cais thiab wrinkles tsis pub rau sab hauv thiab sab nrauv ntawm cov yeeb nkab steel.Cov teeb meem no yuav tsum tau muab tshem tawm tag nrho.Qhov tob clearance yuav tsum tsis txhob ntau tshaj qhov tsis zoo sib txawv ntawm nominal phab ntsa thickness, thiab qhov tseeb phab ntsa thickness ntawm clearance yuav tsum tsis txhob tsawg tshaj li qhov tsawg kawg nkaus tso cai phab ntsa thickness.Qhov tseem ceeb yog siv cov txheej txheem sib txawv raws li cov xwm txheej sib txawv, xws li kev siv cov khoom siv adiabatic thiab cov khoom siv refractory los thaiv cov nplaim taws los ntawm kev kub hnyiab ntawm cov qauv hlau ncaj qha, txo qhov ceev ntawm cov cua kub hloov thiab ncua lub sij hawm ntawm qhov kub thiab txias thiab lub zog tsis muaj zog ntawm cov qauv steel. .Tab sis txawm li cas los xij, txoj ntsiab cai yog tib yam.Fireproof txheej yog ib hom kev ntsuas hluav taws kub siab tshaj plaws tam sim no.Vim tias muaj kev cuam tshuam ntawm impurity ntsiab ntawm qhov zoo ntawm Changsha pipeline yeeb nkab, cov khoom lag luam qib siab muaj cov kev cai nruj heev rau kev tswj hwm cov khoom tsis zoo thiab suav nrog hauv Changsha pipeline yeeb nkab.Nws yog ib qho tsim nyog los tswj cov ntsiab lus ntawm ntau yam impurity ntsiab nyob rau hauv qis heev kom deb li deb tau, thiab cov txheej txheem refining sab nraum lub cub tawg yog feem ntau siv nyob rau hauv ntau lawm kom nws huv si.General boiler tube kub yog qis dua 350 ℃, cov yeeb nkab hauv tsev yog tsim los ntawm tsis muaj.10, 20 carbon bonded steel Changsha yeeb nkab los yog txias drawn yeeb nkab.
Tshuaj muaj pes tsawg leeg
L245 Pipeline Steel, Qhov hnyav suav cov mis: [(sab nraud txoj kab uas hla - phab ntsa thickness) * phab ntsa thickness] * 0.02466 = kg / m (qhov hnyav ib meter)
