Tsis ntev los no, ib pawg ntawm cov txheej txheem siab ASTM A789 S2205 (UNS S31803 / S32205) duplex stainless hlau kav tau ua tiav kev soj ntsuam zoo thiab tau raug xa mus rau Russia. Cov khoom no yog npaj rau siv nyob rau hauv loj loj hauv zos refining thiab tshuaj ua tej yaam num, ib zaug dua qhia peb exceptional mov peev xwm nyob rau hauv lub duplex stainless hlau qhov chaw.
Vim li cas Lavxias teb sab kev lag luam tej yaam num nyiam S2205 duplex stainless hlau?
Nrog rau kev loj hlob txuas ntxiv ntawm cov roj thiab roj, desalination thiab hnyav kev lag luam kev lag luam nyob rau hauv Russia, kev xav tau nruj zuj zus tau muab tso rau ntawm qhov kev tiv thaiv corrosion thiab muaj peev xwm siab ntawm cov khoom siv hluav taws xob sib pauv. Muab qhov kev xav tau tseem ceeb rau kev tiv thaiv corrosion zoo dua thiab muaj zog txhua yam, Duplex Stainless Steel S2205 (UNS S31803 / S32205) tau tshwm sim raws li cov khoom nyiam rau kev siv hluav taws xob hauv cov khoom xws li roj thiab roj, petrochemical thiab lub zog.

Ua raws li ob txoj cai (ntseeg thiab Lavxias)
Peb muab cov ntaub ntawv ua tiav zoo rau S2205 cov cua kub exchanger raj kom tshem tawm cov teeb meem kev lag luam thiab ua kom tiav tag nrho cov kev cai thoob ntiaj teb thiab Lavxias teb sab.
| Daim ntawv pov thawj / Hom qauv | Kev piav qhia |
|---|---|
| Material Test Certificate (MTC) | Muab khoom raws li EN 10204 3.1 lossis 3.2, xyuas kom tag nrho cov ntaub ntawv raw thiab cov ntaub ntawv tsim tawm |
| Cov ntawv xov xwm Standards | Cov khoom ua tau raws li ASTM A789 / A790, nrog cov ntaub ntawv sib piv ua haujlwm tiv thaiv Lavxias GOST cov qauv |
| Third Party Inspection (TPI) | Kev tshuaj xyuas ua ntej xa khoom xa tuaj (PSI) ua los ntawm SGS, Bureau Veritas, TÜV lossis lwm qhov chaw tso cai |
Kev Tswj Xyuas Zoo: Ua kom ntseeg tau tias txhua lub raj ua tau raws li Lavxias GOST thiab cov qauv thoob ntiaj teb
Rau qhov kev xa tawm no mus rau Russia, peb nruj me ntsis ua raws li cov txheej txheem kev tswj hwm zoo hauv qab no:
**Spectrographic tsom xam (PMI):** Ua kom ntseeg tau tias cov tshuaj muaj pes tsawg leeg (Cr, Ni, Mo, N) ntawm txhua lub raj ua tau raws li tus qauv S2205.
** Tswj ntawm qhov ntev ntev: ** nruj me ntsis tswj sab nraud txoj kab uas hla tolerances thiab ncaj nraim kom tau raws li cov kev cai tshwj xeeb ntawm cov cua kub exchanger raj bundles.
** Kev kuaj corrosion kuj: ** Kev kuaj pitting corrosion raws li ASTM G48 los xyuas kom meej tias cov khoom S2205 tuav tus lej siab Pitting Resistance sib npaug (PREN Ntau dua lossis sib npaug rau 34) hauv ib puag ncig uas muaj chlorides.
** Kev sim ntsuas tam sim no: ** Ua 100% kev tshuaj xyuas kom pom cov kab nrib pleb thiab qhov tsis xws luag ntawm qhov chaw thiab subsurface txheej ntawm cov hlab.
** Kev Ntsuas Ultrasonic: ** Tshwj xeeb rau kev kub siab kub exchanger raj, tshuaj xyuas rau minuscule defects nyob rau hauv lub raj phab ntsa.
**Hydrostatic testing:** Subjecting txhua lub raj mus rau high-pressure hydrostatic testing kom paub meej tias qhov tsis muaj qhov xau tag nrho hauv lub tshuab hluav taws xob kub siab.
Tshwj xeeb ntim rau Lavxias teb sab kev nyab xeeb (Arctic-phooj ywg ntim)
Muab rau hauv tus account lub sijhawm thauj mus los ntev hauv Russia thiab nws cov huab cua txias hnyav, peb tau txhawb nqa peb cov ntim raws li hauv qab no:
Kev Tiv Thaiv Thaum Kawg: Lub kaus mom hnyav yas kawg yog siv los tiv thaiv kev ya raws los yog kev sib kis ntawm cov chaw sab hauv.
Kev tiv thaiv xeb: Tsim nyog tus nqi ntawm cov roj tiv thaiv xeb yog siv rau ntawm qhov chaw (raws li cov neeg siv khoom thov), ua raws li ntim rau hauv hexagonal bundles lossis ntim cov thawv ntoo.
Lub thawv ntoo muaj zog: Peb siv lub thawv ntoo tsis muaj fumigation - ua raws li ISPM15- tus qauv los tiv thaiv cov khoom lag luam tiv thaiv kev puas tsuaj thaum lub caij tsheb thauj mus los.
