Qhia rau Kev Yuav 2507 Stainless Hlau Rods rau Siab Hlab Hlais

Cov Khoom Siv Tshuaj Europe Cov Khoom Siv Cov Khoom Siv Cov Khoom Siv Cov Khoom Siv Tshwj Xeeb Hauv Chlor-Alkali Reactors Thiab Cov Khoom Kub Siab Piping

Yuav Tsum Tau Ua Haujlwm:
Kev muab cov 500 txias-kos cov hlau nplaum stainless hlau ua los ntawm qib 2507 (lub cheeb: 80 mm, ntev: 6 meters) rau cov tshuaj lom neeg hauv Spain. Cov khoom siv yuav raug siv rau kev tsim cov nkoj siab uas ua rau cov kab chloride ion (cl 0.) -containing xov xwm.

Ua raws cai:

EU Kev Qhia Ua Siab Siab (Ped 2014\/68 \/ EU):Daim ntawv pov thawj CE yuav tsum muaj. Yuav tsum tau muab cov ntaub ntawv pov thawj cov ntaub ntawv ua raws EN 10204: 2018 ntaus 3.1 \/ b, kev lees paub ua raws li cov tshuaj lom neeg thiab cov kws kho mob tau teev nyob rau hauv en {4}}: 2014.

Welding txheej ua raws cai:Cov kab ntawv yuav raug muab rau hauv kev txhawb nqa cov hlau rau cov hlab ntsha siab. Txhua welded pob qij txha yuav tsum tau ntsib en iso 15614-7}} cov txheej txheem tsim nyog. Welders yuav tsum muaj ntawv pov thawj raws li en ISO 9606.

Corrosion Kuj:Cov ntaub ntawv yuav tsum muaj pitting tiv taus tus lej (pren) ntau dua los yog sib npaug nrog 40 kom ntseeg tau tias desility nyob ib puag ncig.

 

Cov Neeg Siv Cov Ntsiab Lus:
The client has previously experienced multiple project certification failures and a 2-month schedule delay due to suppliers' inability to provide complete and compliant documentation. Lawv tau ceev kom ib-nres, tag nrho txoj kev daws teeb meem.
Weld Seams tau raug rau peb-tog neeg tsis yog kev sib tw kom tau raws li cov txheej txheem kev lees paub ntawm en {2}} (standed rau welded txheej txheem steel).

 

Gnee Mekas daws teeb meem

Daim ntawv pov thawj CE thiab cov ntaub ntawv pov thawj:
Gnee lub chaw yog ped 2 {{{{}} 14\/68 \/ eu muaj ntawv pov thawj. Rau qhov project no, peb muab rau 1 {{{{{{{}} 204: 2018 Hom Cov Khoom Siv Cov Khoom Siv Kom meej: Cr 25.5%, Ni 7.0%, n 0.26%.
Pren tau muab suav raws li: pren {{{{{{}}}}}} {}}}. {}}}}. {{}}}}43.26(Zoo saum toj no qhov yuav tsum tau tsawg ntawm 40).
SGS thib peb-tog spectrometry daim ntawv tshaj tawm yog suav nrog txhawm rau txheeb xyuas qhov pib sib xws.

Cov Khoom Siv Neeg Kho Tshuab:

Lub zog tensile: 850 MPA

Peple Zog: 600 MPA

Elongation: 28%
All values ​​meet the EN 10088-3 standard for super duplex stainless steels.

Vuam ntawm 2507 Stainless Hlau Tuav:

Cov txheej txheem vuam:Gtaw (Tig Vuam)

Tus tub lim hlau:ER2594 (25CR {-9 ni -4 mo {}}. 3n)

Muab Hlau:Ferrite cov ntsiab lus kwv yees. 50%, ua kom muaj kev sib npaug ntawm cov micructivedure

Viaj Ntsej Muag Kev Tsim Kho Kev Lag Luam (PQR):Nyob rau hauv raws li en iso {15614-7, npog cov tsis muaj vuam tam sim no (12-10 cm \/ min), thiab kub tshaj lossis sib npaug nrog 150 degree). Xyuas kom paub tseeb los ntawm lub koom haum thib peb, lees paub weld tensile lub zog ntau dua los yog sib npaug rau 800 mpa, txuam nrog lub zog khoom muaj zog.
