Cov kav dej tsis sib haum yog ib qho tseem ceeb hauv kev tsim kho kev lag luam thiab kev sib txuas lus hauv tsev. Vim tsis muaj seams nyob rau hauv kev tsim ntawm xws li qhov chaw, peb muaj peev xwm hais tias lawv yog cov feem ntau ruaj ntawm lawv hom. Raws li kev xyaum qhia, cov kav dej seamless yog qhov tseeb los ntawm kev ua kom muaj zog rau lub cev thiab kev ntxhov siab, thiab yog li ntawd muaj cov yam ntxwv ua haujlwm siab.
Scope of application
Raws li peb tau sau tseg lawm, cov khoom no yog cov yam ntxwv ntawm kev ua haujlwm siab. Nws yog vim cov khoom zoo no uas lawv tau siv rau hauv cov chaw uas yuav tsum muaj kev ntseeg siab dua. Piv txwv li, cov qauv tuab-walled ntawm cov khoom siv no yog siv thaum tso dej thiab cov kav dej. Kub dov seamless kav yog dav siv nyob rau hauv cov roj thiab roj kev lag luam thiab mechanical engineering. Tsis tas li ntawd, cov khoom no yog siv rau hauvkev siv pej xeem. Nws tseem tsim nyog sau cia tias feem ntau ntawm cov khoom tsim nyob rau hauv CIS lub teb chaws (xws li seamless yeeb nkab GOST 8732-78) raug xa mus rau ntau lub teb chaws Europe.
Ntau yam
Raws li phab ntsa tuab, cov khoom no tau muab faib ua ob hom:
- Thick-walled.
- Thin-walled.
Nyob rau hauv rooj plaub no, qhov dav ntawm phab ntsa ntawm thawj hom ntawm qhov sib txawv ntawm 12.5 txog 40.0 millimeters. Thin-walled yeeb nkab - seamless txias-tsim - muaj phab ntsa dav ntawm 6 mus rau 12.5 millimeters.
Raws li qhov tseeb ntawm kev tsim cov kab, cov kav dej no tuaj yeem muab faib ua cov khoom zoo tib yam thiab cov khoom siv siab. Qhov ntev ntawm cov hlau nws tus kheej tuaj yeem yog 4 txog 12.5 meters lossis ntau dua.
khoom
Ntau zaus, seamless kav yog tsim los ntawm high-strength alloy los yog carbon hlau. Ob qho khoom siv yog qhov txawv los ntawm kev ntseeg siab thiab kev ua haujlwm zoo. Ua tsaug rau qhov no, cov kav dej seamless muaj qhov tiv taus corrosion, tshuaj lom neeg thiab lwm yam tshuaj.
Nyob ntawm seb hom hlau twg tau siv rau hauv kev tsim cov khoom, cov kws txawj paub qhov txawv ntawm ntau hom seamless kav:
- Nrog cov qauv ntawm cov khoom siv kho tshuab.
- Nrog cov qauv ntawm cov tshuaj muaj pes tsawg leeg.
- Nrog normalization ntawm ob qho tib si (chemical thiab mechanical) yam ntxwv.
- Tsis hwm cov khoom thiab muaj pes tsawg leeg.
Los ntawm txoj kev, kev tsim khoom
cov no yog plaub. Nws tuaj yeem yog: forging, dov, nias lossis kos duab. Txawm li cas los xij, tsis muaj teeb meem kev tsim khoom siv li cas, cov khoom zoo li no yuav tsum muaj zog ntau npaum li qhov ua tau thiab tiv taus rau sab nraud aggressive yam.
Zaj lus
Yog li, cov kav dej seamless yog ib qho ntawm cov khoom siv ruaj khov thiab tiv taus siv hauv kev lag luam thiab kev sib txuas lus hauv nroog. Xws li kev siv ntau yam yog vim muaj kev ua haujlwm siab ntawm cov khoom no. Thiab qhov no, nyob rau hauv lem, yog ib tug tshwj xeeb seamless manufacturing txoj kev thiab siv cov feem ntau check steel qib - alloy thiab carbon.

Lub laub-hauv haum muaj cov xov sab nraud nrog rau sab nraud hexagon. Nominal passage yog 6 mm. Lub sealing threaded kev twb kev txuas yog coated. Kev sib dhos txoj haujlwm tuaj yeem yog ib qho. Cov qauv tsim ua haujlwm ntawm lub hauv paus ntsiab lus sib txuas. Kev ua haujlwm siab sib txawv ntawm 0.95 txog 6 bar. Ua haujlwm siab nyob ntawm qhov kub thiab txias yog sib npaug ntawm qhov txwv ntawm 0.95 txog 14 bar

Cov yeeb nkab steel yog lub raj cylindrical thiab yog cov khoom siv tshaj plaws hauv kev lag luam steel. Kev siv cov yeeb nkab steel tseem ceeb yog thauj cov roj, roj thiab dej mus rau qhov ntev. Hauv cov khoom siv hauv tsev, xws li cov tub yees, cov kav dej zoo tib yam yog siv, nrog rau hauv cov cua sov thiab dej
Qhov sib npaug ntawm kev siv dej thiab kev huv yog qhov tsim nyog suav hauv kev tsim cov chaw thiab siv dej
Ib qho ntawm cov ntaub ntawv xav tau los ntawm lub tuam txhab kev lag luam thaum muab daim ntawv tso cai rau kev siv lub cev dej los yog thaum muab daim ntawv tso cai rau kev rho tawm cov dej hauv av yog qhov sib npaug ntawm kev siv dej thiab pov tseg dej. Kev tswj xyuas dej no tseem yuav tsum tau ua thaum tsim ib yam khoom ntawm lub teb chaws kev lag luam lossis ib lub tsev nyob

Kev lag luam niaj hnub ua tsis tau yam tsis muaj cov kav dej zoo. Muaj ntau hom ntawm lawv. Dab tsi yog pawg ntawm cov kav dej, yuav ua li cas txiav txim siab lawv, tau piav qhia hauv kab lus
Seamless steel kav hauv lub ntiaj teb niaj hnub no
Ib kab lus hais txog dab tsi seamless steel kav tuaj yeem ua lag luam niaj hnub no. Yuav ua li cas ntau lawm txoj kev tsim rau cov khoom no, yuav ua li cas los txiav txim lawv zoo thiab tsis? Tsab ntawv hais txog qhov zoo ntawm cov khoom no tuaj yeem muaj, nrog rau cov yam ntxwv ntawm kev ua haujlwm uas cuam tshuam rau kev tsim khoom thiab kev siv, lawv txawv
