1. Dab tsi yog qhov tsawg kawg nkaus phab ntsa thickness ntawm 10 # seamless steel yeeb nkab rau kev siv cov qauv?
Teb: Raws li GB / T 8163 tus qauv, qhov tsawg kawg nkaus phab ntsa thickness ntawm 10 # seamless steel yeeb nkab rau kev siv cov qauv thiab cov dej siv thauj mus los yog 1.5 hli (rau cov kav dej nrog txoj kab uas hla sab nraud tsawg dua lossis sib npaug li 14 hli). Rau cov kav dej uas loj dua sab nraud, qhov tsawg kawg nkaus phab ntsa thickness nce raws li (piv txwv li, sab nraud txoj kab uas hla 57mm, qhov tsawg kawg nkaus phab ntsa thickness 3.5mm), uas yog txiav txim los ntawm cov kabmob muaj peev xwm thiab kev siv tshuab.
2. 35 # seamless steel yeeb nkab puas tuaj yeem welded? Dab tsi yuav tsum tau them sai sai rau thaum vuam?
Teb: Yog, 35 # seamless steel yeeb nkab tuaj yeem welded, tab sis vim nws yog cov pa roj carbon nruab nrab, qhov vuam kev ua tau zoo dua qis dua - carbon steel (10#, 20#). Thaum lub sij hawm vuam, nws yog ib qho tsim nyog yuav tau xyuam xim rau: preheating qhov chaw vuam mus rau 150-250℃ua ntej vuam los tiv thaiv cov kab nrib pleb; siv tsawg-hydrogen vuam electrodes (xws li E5015) kom txo cov ntsiab lus hydrogen hauv vuam; Kev kho cua sov tom qab vuam (tempering ntawm 550-600 degree) txhawm rau tshem tawm cov kev ntxhov siab ntawm vuam thiab txhim kho qhov toughness ntawm vuam.
3. Dab tsi yog lub zog tensile ntau ntawm 20 # seamless steel yeeb nkab?
Teb: Raws li lub teb chaws tus qauv, lub zog tensile ntawm 20 # seamless steel yeeb nkab yog 410-550MPa, lub zog tawm los yog ntau dua los yog sib npaug rau 245MPa, thiab elongation yog ntau dua los yog sib npaug rau 25%. Tus nqi tshwj xeeb yuav txawv me ntsis raws li cov txheej txheem tsim khoom (kub dov, kos duab txias) thiab lub xeev kho cua sov, tab sis nws yuav tsum ua kom tau raws li qhov yuav tsum tau ua ntawm GB / T 8163 tus qauv.
4. Dab tsi yog vim li cas rau corrosion ntawm seamless steel kav hauv kev lag luam tshuaj? Yuav tiv thaiv li cas?
Teb: Cov laj thawj tseem ceeb rau kev xeb yog: tshuaj lom neeg corrosion los ntawm acidic, alkaline lossis ntsev- muaj cov xov xwm hauv kev lag luam tshuaj; electrochemical corrosion tshwm sim los ntawm kev tsim ntawm micro- roj teeb nyob rau saum npoo ntawm cov kav hlau. Txoj kev tiv thaiv: xaiv corrosion-cov qib steel resistant (xws li 316L stainless hlau seamless kav) rau cov xov xwm muaj zog corrosive; coated rau sab hauv thiab sab nrauv ntawm cov kav hlau steel nrog tiv thaiv - coatings (xws li epoxy resin, polyethylene); siv cov tshuaj tiv thaiv corrosion hauv cov khoom thauj nruab nrab kom txo tau cov corrosion.
5. Dab tsi yog qhov txawv ntawm kub - dov thiab txias - kos 10 # seamless steel yeeb nkab?
Teb: Kub- dov 10 # seamless steel yeeb nkab: tsim los ntawm cov txheej txheem kub dov, nrog cov kab loj sab nraud thiab phab ntsa tuab, qhov ntxhib saum npoo, qhov tsis tshua muaj qhov tseeb, tab sis cov khoom siv tau zoo thiab tus nqi qis, tsim nyog rau cov qauv dav dav thiab qis - kev thauj mus los ntawm cov kua dej. Txias- kos 10# seamless steel yeeb nkab: tsim los ntawm cov txheej txheem kos duab txias los ntawm kub- dov yeeb nkab, nrog cov kab me me sab nraud thiab phab ntsa tuab, du nto, qhov siab qhov tseeb, cov khoom siv zoo, tab sis tus nqi siab, haum rau precision mechanical qhov chaw thiab siab -precision fluid transport pipelines.
