Cov pa roj carbon steel taub qab vuam lub taub hau yog lub hau kawg ntawm cov hlab ntsha siab, uas yog ib qho tseem ceeb ntawm cov kabmob siab thiab ua lub luag haujlwm sib khi. Cov pa roj carbon steel taub qab vuam lub taub hau yog ib qho yog ua rau sab sauv thiab qis hauv qab ntawm lub tank siab, thiab lwm yam yog tias cov yeeb nkab yog qhov kawg, thiab tsis npaj kom ntev mus rau pem hauv ntej, ces siv lub taub hau rau sealing cov yeeb nkab hauv. daim ntawv ntawm ib tug weld. 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. Carbon steel taub qab weld taub hau yog ib qho tseem ceeb ntawm cov khoom siv ntawm lub nkoj siab hauv ntau qhov kev lag luam, xws li petrochemical, nuclear fais fab, kev txuag dej, khoom noj, tshuab, khoom siv kho mob, chiv, nkoj tsim, thiab lwm yam., Carbon steel taub qab vuam taub hau yog siv rau hauv ntau yam khoom siv ntim 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.
Cov khoom siv feem ntau siv rau carbon steel taub qab vuam taub hau: (20 #, A3, Q235, Q235A, Q235B, 20G, Q245R, Q345, Q345R, 16Mn, ASTM A105, 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;
