Seamless kavtau muab faib ua cov kav dej kub dov seamless thiab txias dov seamless kav. Seamless kav yog tsim los ntawm tho ib lub billet los yog ib qho khoom puag ncig nrog ib tug mandrel, uas yog ib tug tiaj tus pas nrig cylindrical siv los tsim cov kab noj hniav sab hauv los yog txiav cov duab cylindrical. Cov txheej txheem ua rau muaj qhov sib xws thiab puag ncig ntu ntawm cov yeeb nkab, tsis muaj vuam seams. Qhov no ua rau lawv zoo tagnrho rau cov ntawv siv high-pressure, raws li lawv tuaj yeem tiv taus kev ntxhov siab ntau dua li cov kav dej welded. Hauv tsab xov xwm no, peb yuav tham txog cov txheej txheem kev tsim cov yeeb nkab seamless thiab nws qhov zoo.
Txheej txheem ntau lawm
Kev tsim cov kav dej seamless muaj ob peb kauj ruam tseem ceeb. Cov no suav nrog:
1. Kev Npaj Billet: Thawj kauj ruam yog npaj cov billets los yog cov khoom tuav uas yuav siv los ua cov kav dej seamless. Qhov zoo ntawm cov billets yog qhov tseem ceeb rau kev ua tiav ntawm cov txheej txheem.
2. Cua sov: Cov billets yog rhuab mus rau qhov kub ntawm 1200 degree thiab 1300 degree kom lawv mos thiab ua haujlwm ntau dua.
3. Piercing: Lub rhuab billet yog muab tso rau ntawm ib lub zeb tho, qhov twg ib tug mandrel yog ntxig los ntawm qhov chaw ntawm lub billet. Raws li lub mandrel hla dhau, nws tsim cov kab noj hniav sab hauv ntawm cov yeeb nkab.
4. Rolling: Lub pierced billet yog ces dhau los ntawm ib tug series ntawm dov mills los ua tus yam xav tau txheej kab thiab phab ntsa thickness.
5. Sizing: Tom qab dov, cov yeeb nkab yog qhov loj me rau nws qhov kawg qhov ntev siv lub tshuab sizing. Cov kauj ruam no kuj txhim kho lub roundness thiab straightness ntawm cov yeeb nkab.
6. Kev Ncaj Ncees: Cov yeeb nkab yog tom qab ntawd ncaj qha siv lub tshuab ncaj kom tshem tawm cov kev khoov los yog distortions.
7. Kev ua tiav: Cov kauj ruam kawg yog ua kom tiav cov yeeb nkab los ntawm kev txiav nws mus rau qhov ntev uas yuav tsum tau ua, thiab siv cov kev kho deg tsim nyog.
Qhov zoo ntawm Seamless Pipes
1. Lub zog muaj zog: Cov kav dej seamless yog tsim los ntawm ib qho ntawm cov hlau, uas ua rau lawv muaj zog dua cov kav dej welded. Lawv tuaj yeem tiv taus siab dua thiab kev ntxhov siab yam tsis muaj deformation lossis tawg.
2. Uniformity: Cov txheej txheem seamless yeeb nkab tsim ua rau ib qho zoo kawg nkaus puag ncig ntawm cov yeeb nkab, uas ua kom cov yeeb nkab phab ntsa thickness thiab txoj kab uas hla. Qhov no ua rau lawv txhim khu kev qha thiab kwv yees.
3. Resistance rau Corrosion: Seamless kav yog resistant rau corrosion, uas ua rau lawv haum rau siv nyob rau hauv corrosive ib puag ncig. Qhov no yog qhov tseem ceeb tshwj xeeb hauv kev siv xws li roj thiab roj drilling thiab kev thauj mus los, qhov twg cov kav dej tau raug cov tshuaj hnyav thiab dej hiav txwv.
4. Versatility: Seamless kav dej muaj ntau yam thiab siv tau rau ntau yam kev siv. Lawv feem ntau siv hauv kev lag luam roj thiab roj, kev lag luam tsheb, kev tsim kho kev lag luam, thiab lwm yam.
5. Txo Kev Kho: Cov kav dej seamless yuav tsum muaj kev saib xyuas tsawg dua li cov kav dej welded vim lawv muaj cov pob qij txha tsawg thiab cov seam welds uas tuaj yeem tawg lossis tawg.
6. Nqi-zoo: Txawm hais tias cov kav dej seamless yog kim dua los tsim dua cov kav dej welded, lawv cov kav ntev thiab kev ua haujlwm ntev ua rau lawv siv nyiaj ntau dua rau lub sijhawm ntev. Lawv xav tau kev saib xyuas tsawg dua thiab muaj lub neej ntev dua, uas ua rau lawv muaj peev xwm zoo dua.
