1. Dab tsi yog seamless carbon steel yeeb nkab?
Seamless carbon steel yeeb nkab yog ib hom hlau yeeb nkab ua los ntawm carbon steel billet los ntawm kub dov, txias dov los yog txias kos duab yam tsis muaj vuam seam ntawm lub cev yeeb nkab. Nws yog tsim los ntawm ncaj qha piercing lub billet rau hauv lub hollow raj dawb paug thiab ces ua nws los ntawm ntau yam dov txheej txheem. Piv nrog cov welded steel kav, seamless carbon steel kav muaj ntau dua cov qauv kev ncaj ncees, muaj zog siab tsis kam thiab zoo corrosion kuj, thiab yog dav siv nyob rau hauv siab - siab, siab - kub thiab lwm yam hnyav ua hauj lwm ib puag ncig.
2. Dab tsi yog cov khoom tseem ceeb ntawm seamless carbon steel kav?
Cov ntaub ntawv tseem ceeb ntawm seamless carbon steel kav yog carbon steel, uas yog muab faib ua cov pa roj carbon tsawg, nruab nrab carbon steel thiab siab carbon steel raws li cov ntsiab lus carbon. Cov khoom siv feem ntau suav nrog ASTM A106 (Gr.B, Gr.C), ASTM A53 (Gr.A, Gr.B), API 5L (Gr.B, X42, X52), GB / T 8163 (20#), GB / T 9948 (20G), thiab lwm yam. Ntawm lawv, 20 # cov khoom siv zoo tshaj plaws thiab cov khoom siv yas weldability, thiab yog haum rau feem ntau cov kev lag luam thiab engineering teb.
3. Dab tsi yog qhov kev qhia tshwj xeeb ntawm seamless carbon steel kav?
Qhov tshwj xeeb ntawm seamless carbon steel kav yog txiav txim siab los ntawm sab nraud (OD), sab hauv (ID), phab ntsa thickness (WT) thiab ntev. Qhov dav dav sab nraud yog 10mm{10}}630mm, phab ntsa tuab yog 1mm-50mm, thiab qhov ntev feem ntau yog 6m, 9m lossis 12m (customizable raws li cov neeg siv khoom xav tau). Tsis tas li ntawd, cov yeeb nkab tuaj yeem muab faib ua seamless round yeeb nkab, seamless square yeeb nkab, seamless rectangular yeeb nkab, thiab lwm yam raws li tus ntoo khaub lig-sectional duab, cov seamless round yeeb nkab yog cov feem ntau siv nyob rau hauv kev lag luam txawv teb chaws.
4. Dab tsi yog qhov txawv ntawm kub - dov seamless carbon steel yeeb nkab thiab txias - kos seamless carbon steel yeeb nkab?
Qhov sib txawv tseem ceeb ntawm kub- dov thiab txias- kos seamless carbon steel kav yog nyob rau hauv cov txheej txheem technology, kev ua tau zoo thiab daim ntawv thov scenarios. Kub- dov seamless kav yog ua tiav ntawm qhov kub siab (siab tshaj 1000 degree), nrog rau kev tsim khoom loj, tuab phab ntsa tuab, ntxhib nto, tab sis zoo toughness thiab ductility, haum rau loj - txoj kab uas hla, tuab - cov kav dej thiab lub sijhawm uas yuav tsum tau muaj kev thauj khoom siab - cov kabmob muaj peev xwm. Txias-cov kav dej seamless tau ua tiav ntawm chav tsev kub, nrog cov phab ntsa me me, du nto, siab qhov tseeb, tab sis kuj tsis tshua muaj zog, haum rau me me - txoj kab uas hla, nyias- cov kav dej thiab lub sijhawm uas yuav tsum tau muaj siab precision, xws li precision machinery thiab instrumentation.
5. Dab tsi yog qhov siab - bearing muaj peev xwm ntawm seamless carbon steel kav?
Lub siab-cov kabmob muaj peev xwm ntawm seamless carbon steel kav yog nyob ntawm cov khoom, phab ntsa thickness, txheej kab uas hla thiab ua hauj lwm kub. Feem ntau hais lus, qhov siab dua cov ntsiab lus ntawm cov khoom siv, cov phab ntsa tuab dua, qhov me me ntawm cov kab uas hla sab nraud, thiab qhov kub ua hauj lwm qis dua, qhov siab dua - cov kabmob muaj peev xwm. Piv txwv li, lub siab tshaj plaws ua hauj lwm siab ntawm ASTM A106 Gr.B seamless yeeb nkab nrog sab kab uas hla 108mm thiab phab ntsa thickness 10mm yuav ncav cuag 10MPa nyob rau hauv chav tsev kub, uas yog dav siv nyob rau hauv high - siab thauj mus los. Peb tuaj yeem muab kev tshaj lij-cov kev pabcuam suav nrog raws li kev ua haujlwm tshwj xeeb ntawm cov neeg siv khoom.
