Seamless steel yeeb nkab xov xwm qhia

27 ximseamless steel tubes, yog27SiMn seamless steel raj, yog ib qho ntawm cov khoom siv rau seamless steel raj.Cov ntsiab lus carbon yog nyob nruab nrab ntawm 0.24 thiab 0.32%.Lub simn ib kab yog vim muaj tsib lub ntsiab (carbon C, silicon Si thiab manganese).Hauv Mn, phosphorus P, thiab sulfur S, cov ntsiab lus ntawm silicomanganese yog li 1.10 txog 1.40%.27simn seamless yeeb nkab yog tsim rau cov fais fab nroj tsuag, boiler cog, tshuaj kev lag luam, tsheb, nkoj accessories.
27simn seamless steel txoj kev xav luj mis seamless steel raj ib meter qhov hnyav W = 0.02466 * S(DS)
Lub ntsiab lus: D = Sab nraud txoj kab uas hla S = Phab ntsa thickness xam piv txwv: Rau ib tug seamless steel yeeb nkab nrog ib tug sab nraud txoj kab uas hla ntawm 60 hli thiab phab ntsa thickness ntawm 4 hli, xam qhov hnyav ib m.
Qhov hnyav ib m = 0.02466 * 4 * (60-4) = 5.52Kg

Tus nqi ntawm seamless steel hlab yog hais txog 500-800 yuan / tuj siab tshaj qhov ncaj seam welded hlab, thiab tus nqi ntawm seamless steel hlab yog 800-1200 yuan / tuj siab tshaj qhov seamless steel tubes.Seamless steel yeeb nkab ntau lawm txheej txheem | Lub seamless steel yeeb nkab yog ua tiav los ntawm kev txo qhov nro, thiab cov txheej txheem nro txo ​​yog cov txheej txheem txuas ntxiv uas cov hlau hollow tsis muaj mandrel.Nyob rau ntawm qhov chaw ntawm kev lav qhov zoo ntawm cov vuam ntawm niam raj, qhov nro txo ​​cov txheej txheem ntawm cov yeeb nkab welded yog kom sov tag nrho cov yeeb nkab welded mus rau 950 degrees Celsius los yog ntau tshaj, thiab ces mus rau ntau yam ntawm sab nraud diameters thiab phab ntsa. ib tug nro reducer (tag nrho ntawm 24 hla ntawm lub stretcher).Lub tuab tiav tube, cov kub dov steel raj uas tsim los ntawm cov txheej txheem no thiab cov zoo tib yam high-frequency welded yeeb nkab yog qhov tseem ceeb sib txawv.Tom qab cua sov hauv cov cua kub cua sov, cov qauv metallographic thiab mechanical zog ntawm cov vuam thiab cov niam txiv hlau tuaj yeem ua tau zoo ib yam.Qhov thib ob nro reducer dov thiab tsis siv neeg tswj ua rau cov yeeb nkab qhov tseeb qhov tseeb (tshwj xeeb tshaj yog cov yeeb nkab roundness thiab phab ntsa thickness raug) zoo dua li cov yeeb nkab seamless zoo sib xws.Cov raj xa dej thiab cov raj boiler uas tsim nyob rau hauv cov teb chaws tsim nyob hauv lub ntiaj teb tau txais ntau tuswelded raj seamless txheej txheem.Nrog rau txoj kev loj hlob ntawm tib neeg, lub domestic kub dov welded raj tau maj mam hloov cov seamless hlab.

Seamless steel yeeb nkab yog ib hom ntev seem steel nrog hollow seem thiab tsis muaj seam ncig.Hlau muaj qhov hollow seem, ntau cov kav dej siv los thauj cov kua dej, xws li xa cov roj, nkev, roj, dej thiab qee yam khoom siv xws li cov kav dej.Seamless yeeb nkab yog muab faib ua cov raj kub-kuav los tiag, txias-kuav los tiag raj, txias drawn tubes, extruded raj, yeeb nkab jacking.Seamless steel yeeb nkab rau cov kua xa tawm yog siv los thauj dej, roj, roj thiab lwm yam kua dej feem ntau seamless steel yeeb nkab.Qhov qis thiab nruab nrab siab boiler seamless steel yeeb nkab yog siv nyob rau hauv kev tsim ntawm ntau yam qauv ntawm qis thiab nruab nrab siab boiler superheated chav kav, boiling dej kav thiab superheated chav locomotive boiler raj, pa luam yeeb yeeb nkab, me me yeeb nkab thiab arch cib yeeb nkab nrog high-zoo. carbon qauv Steel kub-kuav los tiag thiab txias-draw seamless steel yeeb nkab.Qhov sib txawv ntawm seamless steel raj rau cov kua dej thiab seamless steel raj rau qis thiab nruab nrab siab boilers: Qhov sib txawv ntawm GB / T8163-1999 thiab seamless steel raj rau cov kua dej seamless steel raj thiab qis- thiab nruab nrab-siab boilers Seamless steel raj yog ib hom ntawm seamless steel raj nrog lub hollow seem tsis nyob ib puag ncig Ntev sawb ntawm hlau.Hlau muaj qhov hollow seem, ntau cov kav dej siv los thauj cov kua dej, xws li xa cov roj, nkev, roj, dej thiab qee yam khoom siv xws li cov kav dej.Seamless yeeb nkab yog muab faib ua cov raj kub-kuav los tiag, txias-kuav los tiag raj, txias drawn tubes, extruded raj, yeeb nkab jacking.Seamless steel yeeb nkab rau cov kua kis tau tus mobyog siv los thauj dej, roj, roj thiab lwm yam kua dej feem ntau seamless steel yeeb nkab.Qhov qis thiab nruab nrab siab boiler seamless steel yeeb nkab yog siv nyob rau hauv kev tsim ntawm ntau yam qauv ntawm qis thiab nruab nrab siab boiler superheated chav kav, boiling dej kav thiab superheated chav locomotive boiler raj, pa luam yeeb yeeb nkab, me me yeeb nkab thiab arch cib yeeb nkab nrog high-zoo. carbon qauv Steel kub-kuav los tiag thiab txias-draw seamless steel yeeb nkab.
