Stainless Hlau Ntauwd

Ntauwd yog cov cuab yeej sib cais tseem ceeb hauv cov txheej txheem kev lag luam xws li roj refining, tshuaj ua haujlwm, thiab kev kho cov roj ntsha. Lawv yog tsim los ntawm cov hlab ntsha, lub taub hau, daim tiab, thiab cov khoom siv sab hauv (cov tais, ntim khoom, cov khoom muag, cov khoom ntim, cov demisters, thiab lwm yam), piv txwv xws li cov kab distillation, nqus yees, strippers, thiab cov kab rho tawm. Ntauwd kev khiav hauj lwm tej yam kev mob yog complex, tso siab heev xav tau ntawm tsim, cov ntaub ntawv, thiab manufacturing.

Cov khoom siv feem ntau siv rau stainless hlau yees muaj xws li 304 thiab 316L. Rau cov seem uas muaj cov tshuaj chloride ion concentration lossis kub siab, duplex stainless hlau (2205) lossis qib siab dua alloys (xws li 904L) tuaj yeem xaiv.

Vim tias qhov sib txawv thermal expansion coefficients ntawm stainless hlau thiab carbon hlau, yuav tsum tau muab kev txiav txim siab ntxiv rau cov thermal stress txuam ntawm lub cev ntauwd thiab cov khoom siv sab hauv (xws li ntauwd phaj txhawb rings thiab ntim cov phaj siab) thaum tsim stainless hlau yees. Peb siv cov ntsiab lus finite tsom xam los pab txiav txim siab qhov kev ntxhov siab ntawm cov ntsiab lus sib txuas hauv qhov kub sib txawv loj.

Cov khoom siv sab hauv xws li tus xa khoom, cov tais ntim khoom, thiab cov khoom ntim khoom hauv cov pej thuam yog ua los ntawm cov hlau tsis muaj steel ntawm tib yam lossis qib siab dua li cov pej thuam lub cev kom tsis txhob galvanic corrosion. Rau thaj chaw uas muaj roj-kua yaig (xws li hauv qab ntawm cov khoom noj nkag), Stellite alloy tuaj yeem welded lossis hnav -cov ntaub ntawv tiv thaiv tuaj yeem ntxiv.

Peb tuaj yeem tsim raws li ASME VIII, GB 150, PD 5500. Cov hlau tsis muaj steel ntauwd tuaj yeem tsim nyob rau hauv ib ntu nrog qhov siab tshaj plaws txoj kab uas hla ntawm 5 meters thiab qhov siab tshaj 30 meters. Yog tias nws ntev dhau lawm, nws tuaj yeem tsim nyob rau hauv ntu thiab welded ntawm qhov chaw. Peb tuaj yeem muab ASME U stamp, PED daim ntawv pov thawj, thiab cov ntawv pov thawj hauv zej zog (ABS, DNV, BV, CCS).
