Seamless steel yeeb nkab yog ib hom kev tsim khoom siv, dav siv hauv ntau qhov kev lag luam.Nws yog ib qho square, puag ncig lossis lub voj voos hollow seem steel, uas ua lub luag haujlwm tseem ceeb hauv kev tsim kho kev lag luam.Seamless steel raj kuj tau siv dav hauv cov kav dej, xws li dej, roj, roj, nkev, roj thiab lwm yam khoom siv.Piv nrog rau lwm cov khoom hlau, steel yeeb nkab yog lub teeb steel, nyob rau hauv tib lub zog torsional, qhov zoo tshaj plaws bearing steel.Dav siv nyob rau hauv roj laum yeeb nkab, tsheb tsav ncej, kev tsim kho steel scaffolding thiab lwm yam structural qhov chaw thiab mechanical qhov chaw tsim, tuaj yeem txhim kho tus nqi ntawm cov khoom siv, ua kom yooj yim rau kev tsim khoom, txuag cov ntaub ntawv thiab sijhawm ua haujlwm.
Clssification thiab daim ntawv thov ntawm seamless steel yeeb nkab
1. Cov qauv seamless steel yeeb nkab (GBT 8162-2008), feem ntau yog siv rau cov qauv dav dav thiab cov qauv siv tshuab, nws cov khoom sawv cev (qib): carbon steel, 20,45 steel;Hlau alloyQ345,20Cr, 40Cr, 20CrMo, 30-35CrMo, 42CrMo, lwm.
2. Seamless Steel yeeb nkab rau kev hloov pauv dej (GBT 8163-2008).Feem ntau yog siv hauv engineering thiab cov khoom siv hauv cov kav dej loj.Sawv cev 20, Q 345 thiab lwm yam ntaub ntawv (hom).
3. Seamless steel yeeb nkab rau siab siab thiab nruab nrab siab boilers (GB 3087-2008), yog ib yam ntawm high-zoo carbon qauv steel kub dov txias drawn seamless steel yeeb nkab, siv rau zus tau tej cov ntau yam tsawg siab boiler, nruab nrab siab boiler , boiling dej yeeb nkab, locomotive boiler superheated chav yeeb nkab, loj tso yeeb nkab, me me yeeb nkab, arch cib yeeb nkab, cov khoom sawv cev yog No.10, 20 steel hlau.
4. Kev kub siab boiler nrog seamless steel yeeb nkab (GB5310-2008), siv los tsim cov khoom zoo carbon steel hlau thiab stainless hlau seamless steel yeeb nkab cua sov saum npoo siab thiab siab dua, cov khoom sawv cev rau20g ua, 12Cr1MoVG, 15 CrMoG, thiab lwm yam.
5. Seamless steel yeeb nkab (GB 6479-2000) rau cov khoom siv chiv siab, haum rau cov khoom siv zoo carbon steel thiab alloy steel seamless steel yeeb nkab nrog kev ua haujlwm kub ntawm -40 ℃ thiab ua haujlwm siab ntawm 10-30 mA, sawv cev 20, 16 Mn, 12 CrMo, 12Cr2Mo thiab lwm yam ntaub ntawv.
6. Seamless steel yeeb nkab rau roj av tawg (GB 9948-2006), feem ntau yog siv rau boiler, tshav kub exchanger thiab kua conveying pipeline ntawm roj av smelters, nws cov ntaub ntawv sawv cev yog 20, 12 CrMo, 1Cr5Mo, 1Cr19Ni11Nb, thiab lwm yam.
7. Hlau yeeb nkab rau geological drilling (YB235-70).Nws yog ib yam ntawm cov yeeb nkab steel siv rau cov tub ntxhais drilling hauv Department of geology, uas tuaj yeem muab faib ua cov yeeb nkab laum, laum nplhaib, tub ntxhais yeeb nkab, casing thiab deposition yeeb nkab raws li kev siv.
8. Seamless steel yeeb nkab rau cov tub ntxhais drilling (GB 3423-82).Nws yog seamless steel yeeb nkab siv hauv cov tub ntxhais drilling, xws li laum yeeb nkab, tub ntxhais yeeb nkab thiab casing.
9. Roj drilling yeeb nkab (YB 528-65).Nws yog siv los thicken los yog thicken seamless steel raj ntawm ob kawg ntawm cov roj drilling RIGS.Muaj ob hom steel yeeb nkab, muab faib ua steel hlau thiab cov hlau tsis yog hlau, hlau yeeb nkab txuas, tsis yog hlau yeeb nkab taub qab vuam thiab cov cuab yeej sib txuas.
Vam tias los ntawm cov ntsiab lus saum toj no, peb tuaj yeem muaj kev nkag siab ntxiv ntawm seamless steel yeeb nkab.
