Seamless yeeb nkab (SMLS) yog cov yeeb nkab steel ua los ntawm ib daim hlau uas tsis muaj pob qij txha ntawm qhov chaw. Nws yog ua los ntawm cov hlau ingot los yog ib lub raj khoom dawb los ntawm perforation los ua ib lub raj capillary, thiab ces kub dov, txias dov los yog txias-draw. Cov yam ntxwv ntawm seamless steel kav yog txawv los ntawm lwm yam steel kav. Lawv muaj zog nyob rau hauv corrosion kuj, muaj zog thiab ruaj khov, haum rau ntau lub hom phiaj, thiab muaj zog applicability nyob rau hauv kev tsim kho txheej txheem. Lawv tsis txwv los ntawm tej yam ntuj tso thaum lub sij hawm installation txheej txheem. Cov ntsiab lus yog raws li nram no:

1. Zoo heev hnav tsis kam
Lub thickness ntawm cov khaub-ncaws nyias txheej ntawm cov yeeb nkab seamless yog 3-12 hli, thiab hardness ntawm hnav-resistant txheej tuaj yeem ncav cuag HRC58-62. Kev sib tsoo kev ua tau zoo yog ntau tshaj 2-5 zaug, thiab hnav tsis kam yog ntau dua li cov tshuaj tsuag vuam thiab thermal txau.

2. Kev cuam tshuam zoo heev

Cov yeeb nkab seamless yog ob txheej txheej hlau. Cov txheej hnav-tiv taus thiab cov khoom siv hauv paus yog metallurgically bonded. Lub zog sib txuas yog siab. Nws tuaj yeem nqus tau lub zog thaum lub sijhawm cuam tshuam. Cov txheej hnav-tiv taus yuav tsis poob thiab tuaj yeem siv rau hauv kev vibration thiab cuam tshuam Raws li kev ua haujlwm muaj zog, qhov no dhau mus txog ntawm cov ntaub ntawv pov thawj hnav-resistant thiab cov ntaub ntawv ceramic.
3. Zoo heev kub kuj
Seamless yeeb nkab alloy carbide muaj kev ruaj ntseg ntawm qhov kub thiab txias, thiab hnav-resistant steel phaj yuav siv tau nyob rau hauv 500 ° C.Qhov kub ntawm lwm yam tshwj xeeb yuav tsum tau customized thiab tsim, uas yuav ua tau raws li kev siv nyob rau hauv lub 1200 °. C; Cov ntaub ntawv hnav-tiv taus xws li ceramics, polyurethane, thiab cov ntaub ntawv molecular tsis tuaj yeem ua tau raws li qhov xav tau kub kub los ntawm pasting.

4. Kev sib txuas zoo heev
Lub hauv paus khoom ntawm cov yeeb nkab seamless yog ib qho dav Q235 steel phaj, uas ua kom ntseeg tau tias cov phaj hnav-resistant steel muaj kev tiv thaiv thiab plasticity.
Nws muab lub zog tiv thaiv kev quab yuam sab nraud, thiab tuaj yeem txuas nrog lwm cov qauv los ntawm kev siv vuam, ntsaws vuam, ntsia liaj qhov rooj thiab lwm txoj kev. Kev sib txuas yog ruaj khov thiab tsis yooj yim rau poob. Muaj ntau txoj kev sib txuas ntau dua li lwm cov ntaub ntawv.

5. Kev ua haujlwm zoo heev
Seamless kav tuaj yeem ua tiav rau hauv cov qauv sib txawv raws li qhov yuav tsum tau ua, thiab tuaj yeem ua tiav, txias-tsim, welded, khoov, thiab lwm yam, uas yooj yim siv; lawv tuaj yeem raug txiav-welded rau ntawm qhov chaw, ua kev kho thiab hloov ua haujlwm lub sijhawm-txuag thiab yooj yim, thiab txo qis kev ua haujlwm zoo heev.

6. Kev ua haujlwm siab

Tus nqi ntawm cov yeeb nkab seamless yog me ntsis siab dua li cov hlau dav dav, tab sis xav txog kev pab cuam lub neej ntawm cov khoom, nrog rau cov nqi kho, cov nqi seem, thiab lwm yam, nws qhov kev ua tau zoo-tus nqi sib piv yog ntau dua li ntawm cov hlau phaj dav dav. thiab lwm yam khoom steel.
