Seamless yeeb nkab (SMLS) yog cov yeeb nkab steel uas ua los ntawm ib qho ntawm cov hlau tsis muaj pob qij txha ntawm qhov chaw. Nws yog ua los ntawm steel ingot los yog cov tube khoom dawb paug los ntawm perforation los ua ib tug capillary raj, thiab ces kub dov, txias dov los yog txias drawn. 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. Kev tiv thaiv zoo heev
Lub thickness ntawm cov khaubncaws sab nraud povtseg ntawm cov yeeb nkab seamless yog 3-12 hli, thiab lub hardness ntawm hnav resistant txheej yuav ncav cuag HRC 58-62. Kev sib tsoo kev ua tau zoo yog ntau dua 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 resistant thiab cov khoom siv hauv paus yog metallurgically bonded. Lub zog ntawm daim ntawv cog lus yog siab. Nws tuaj yeem nqus tau lub zog thaum lub sijhawm cuam tshuam. Cov txheej txheej hnav tiv thaiv yuav tsis poob tawm thiab tuaj yeem siv rau hauv kev vibration thiab kev cuam tshuam, nyob rau hauv kev ua haujlwm muaj zog, qhov no yog tawm ntawm qhov ncav cuag ntawm cov khoom siv cam khwb cia thiab cov khoom siv ceramic.
3. Zoo heev kub kuj Seamless yeeb nkab alloy carbide muaj zog stability rau
kub siab, thiab hnav-resistant steel phaj yuav siv tau nyob rau hauv 500 degree C. Qhov kub ntawm lwm yam tshwj xeeb yuav tsum tau customized thiab tsim, uas muaj peev xwm ua tau raws li kev siv nyob rau hauv lub 1200 degree C; Hnav-tiv taus cov ntaub ntawv xws li ceramics, polyurethane thiab cov ntaub ntawv molecular tsis tuaj yeem ua tau raws li qhov xav tau kub kub thaum gluing.
4. Kev ua tau zoo heev
Kev sib txuas Cov khoom siv ntawm cov yeeb nkab seamless yog Q235 dav hlau phaj, uas ua kom ntseeg tau tias cov phaj hnav-resistant steel muaj zog thiab yas.
Nws muab kev tiv thaiv tawm tsam sab nraud quab yuam thiab tuaj yeem txuas nrog lwm cov qauv los ntawm kev siv vuam, ntsaws vuam, ntsia hlau txuas thiab lwm txoj hauv kev. Kev sib txuas yog ruaj khov thiab nws tsis yooj yim rau poob. Muaj ntau txoj kev sib txuas ntau dua li lwm cov ntaub ntawv.
5. Kev ua tau zoo heev
Kev ua cov kav dej seamless 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 ua kev cai welded rau ntawm qhov chaw, ua kev kho thiab hloov ua haujlwm lub sijhawm-txuag thiab yooj yim, thiab txo kev siv zog ntau.
6. Kev ua haujlwm siab
Tus nqi ntawm cov yeeb nkab seamless yog me ntsis siab dua li cov hlau dav dav, tab sis coj mus rau hauv tus account lub neej kev pab cuam ntawm cov khoom, nrog rau cov nqi kho, spare qhov chaw, thiab lwm yam., nws cov kev ua tau zoo-nqi piv yog ntau dua li qhov ntawd. ntawm dav hlau daim hlau thiab lwm yam steel khoom.
