Lub taub hau oval tseem hu ua lub taub hau oval, muab faib ua EHA oval taub hau, EHB oval taub hau. Lub taub hau yog lub hau kawg ntawm lub nkoj siab, uas yog ib qho tseem ceeb ntawm lub siab-cov kabmob thiab ua lub luag haujlwm ntawm kev sib khi. Lub taub hau ntawm cov hlab ntsha siab yog ua kom lub hauv qab sab saum toj thiab hauv qab ntawm lub tank ntawm lub
Lub taub hau oval tseem hu ua lub taub hau oval, muab faib ua EHA oval taub hau, EHB oval taub hau. Lub taub hau yog lub hau kawg ntawm lub nkoj siab, uas yog ib qho tseem ceeb ntawm lub siab-cov kabmob thiab ua lub luag haujlwm ntawm kev sib khi. Lub taub hau lub taub hau siab yog ua rau hauv qab sab saum toj thiab hauv qab ntawm lub tank siab, thiab qhov thib ob yog tias cov yeeb nkab yog qhov kawg thiab tsis tau npaj kom ntev mus rau pem hauv ntej, ces siv lub taub hau los kaw cov yeeb nkab hauv qhov sib txuas. Cov khoom uas muaj cov haujlwm zoo sib xws rau lub taub hau muaj cov louvers thiab lub kaus mom, thiab cov louvers thiab threaded caps yog tshem tau. Tom qab lub taub hau yog welded, nws tsis tuaj yeem disassembled. Lub taub hau zoo yog ncaj qha cuam tshuam rau lub sijhawm ntev kev nyab xeeb thiab txhim khu kev qha ntawm lub nkoj siab. Raws li cov duab geometric sib txawv, lub taub hau tuaj yeem muab faib ua kheej kheej, oval, disc, kheej kheej yas, lub khob hliav qab thiab lub plhaub tiaj tus, ntawm cov uas lub taub hau kheej kheej, oval, disc thiab spherical crown taub hau kuj tseem hu ua convex taub hau. Hauv welding, nws tau muab faib ua pob tw weld taub hau thiab lub qhov (socket weld head).
Lub taub hau oval tau muab faib ua carbon steel, stainless hlau, hlau alloy, tshwj xeeb alloy hlau, duplex stainless hlau, thiab lwm yam. raws li cov khoom ntawm kev tsim khoom; Carbon Steel: (20#, A3, Q235, Q235A, Q235B, 20G, Q245R, Q345, Q345R, 16Mn, ASTM A234WPB, ASTM A105, thiab lwm yam); Tus Hlau Stainless: (304, 304L, s30408, s31603, {}} cr16i4, 91cr26, 022cr17ni12mo2 , thiab lwm yam); Alloy steel: (16MnR, Cr5Mo, 12Cr1MoV, 10CrMo910, 15CrMo, 12Cr2Mo1, A335P22, St45.8/III., A10bB, thiab lwm yam); Cov hlau tshwj xeeb: (TP310S, 904L, Incoloy800, Incoloy825, Incoloy600, Incoloy625, thiab lwm yam); Duplex stainless hlau: (F51, S31803, S2205, F53, 2507, S32750, F55, 2607, S32760, thiab lwm yam).
Feem ntau siv cov npe thiab hom codes ntawm lub taub hau yog raws li nram no:
1. Hemispherical taub hau: hom code: HHA;
2. Oval taub hau: hom code: EHA, EHB;
3. Disc head: hom code: THA, THB;
4. Spherical crown taub hau: hom code: SDH;
5. Lub taub hau hauv qab: Hom Code: FHA;

Lub taub hau oval yog ib qho tseem ceeb thiab tseem ceeb ntawm cov khoom siv lub nkoj siab hauv ntau qhov kev lag luam, xws li petrochemical, nuclear, kev txuag dej, khoom noj, tshuab, khoom siv kho mob, chiv, nkoj tsim, thiab lwm yam. Nws yog siv nyob rau hauv ntau yam khoom siv hauv nkoj xws li cov tso tsheb hlau luam, cov khoom siv hluav taws xob sib hloov, cov yees, cov reactors, boilers, thiab cov khoom sib cais.
