Lub hollow kheej rau cov li qub yog tsim los ntawm steel kauj vuam qauv. Qhov no feem ntau tsim nyog rau cov npav pob nrog cov nominal siab qis dua los yog sib luag rau 5.0MPA (CLASS300). Qhov lub cev ntawm lub cev valve yog qhov hnyav hauv qhov hnyav thiab cov kab noj hniav sab hauv yog qhov yooj yim rau cov txheej txheem, tab sis tshwj xeeb yuav tsum tau them nyiaj rau qhov kev npaj ntawm cov pob txha caj qaum hauv tus tsim kom tiv thaiv lub cev ntawm lub cev tsis zoo. Lub tshuab ua kua hlau ntawm cov hlau ua haujlwm thaum cov txheej txheem surfacing ntawm daim hlau kheej kheej yuav ntws ywj pheej. Txhawm rau kom paub tseeb tias cov kua hlau ua rau lub pas dej molten yog ruaj khov thaum lub sijhawm txias thiab solidification txheej txheem thaum vuam, cov hlau ua kua yuav tsum nco ntsoov nyob rau hauv lub xeev rov qab thaum vuam. Cov txheej kheej kheej ntawm cov hlau pob lub pob valve yog ib qho chaw ua kom nto ntawm qhov chaw kheej kheej, kheej kheej, thiab dav. Thaum lub sijhawm vuam tiav, lub tshuab ua haujlwm tsis siv neeg yuav tsum xyuas kom meej tias lub vuam phom tuaj yeem ncav cuag txhua qhov chaw ntawm chaw. Lub pob hlau stainless pob valve tsis siv neeg surfacing vuam tshuab tuaj yeem ua tiav tau yooj yim ua tiav surfacing ntawm stainless hlau txheej ntawm pob valve kheej kheej rau carbon steel kheej nyob rau saum npoo ntawm qhov chaw ua tau zoo, tshwj xeeb tshaj yog surfacing ntawm lub loj stainless hlau kheej kheej, tsim ib thev naus laus zis nrog cov cuab yeej fwm txoj cai. Tsis siv neeg surfacing yog kev nruam qhov loj-cheeb tsam txheej txheem, thiab qhov zoo ntawm ntau txheej thiab ntau txheej vuam yuav tsum tau lav. Txheeb xyuas qhov tseeb ntawm cov khoom siv vuam vuam thiab cov txheej txheem vuam, ua tau raws li cov txheej txheem cov cuab yeej tsim nyog, thiab ua kom cov khoom ntawm cov khoom, cov khoom sib xws, tsis muaj steel hlau surfacing txheej ntawm cov pa roj carbon steel substrate.
