Thaum tau txais S335J0WP Corten Steel, nws tsis yog - tus qauv txheej txheem (tsis tau teev nyob rau hauv EN 10025-5) ua rau kev pov thawj zoo tshwj xeeb yog qhov tseem ceeb. Yog tias tsis muaj cov txheej txheem kev cai lij choj, tsuas yog tso siab rau tus neeg muag khoom thov tsuas yog muaj kev pheej hmoo tau txais cov ntaub ntawv uas tsis ua raws li qhov yuav tsum tau ua ntawm qhov project{10}} xws li huab cua tsis txaus los yog cuam tshuam rau qhov hnyav. Tus yuam sij rau txo qhov kev pheej hmoo no yog thov thiab txheeb xyuas cov ntaub ntawv zoo. Cov ntaub ntawv tseem ceeb twg yuav tsum cov neeg yuav khoom xav tau los ntawm cov neeg muag khoom kom paub meej S335J0WP qhov zoo? Hauv qab no yog cov lus qhia luv luv, ua pov thawj-raws li cov ntaub ntawv yuav tsum tau ua thiab ntxiv cov ntaub ntawv, nrog rau cov lus qhia ua pov thawj.
Lub ntsiab lus tseem ceeb: Vim li cas Kev Tshawb Fawb Cov Ntaub Ntawv yog qhov tseem ceeb rau S335J0WP
Ob yam tseem ceeb tseem ceeb qhia txog qhov yuav tsum tau ua kom nruj cov ntaub ntawv pov thawj rau qib no:
Tsis yog -Standard Qib Risk: S335J0WP tsis yog tus qauv Corten Steel qib hauv EN 10025-5. Tsis muaj cov ntaub ntawv tshwj xeeb, nws cov tshuaj lom neeg muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab huab cua tsis kam tso siab rau tus neeg muag khoom tus kheej- cov ntaub ntawv tshaj tawm tsuas yog cov pov thawj pom tseeb ntawm kev ua raws li kev ua tau zoo.
Txoj Haujlwm Kev Nyab Xeeb Yuav Tsum Tau: Rau cov qauv siv los yog kev lag luam, S335J0WP lub zog, toughness, thiab corrosion kuj ncaj qha cuam tshuam rau cov qauv kev nyab xeeb. Cov ntaub ntawv zoo xyuas kom cov khoom sib tw tsim cov qauv, zam kev ua tsis tiav ntxov lossis xwm txheej.
Yuav tsum tau ua cov ntaub ntawv zoo los thov
Cov ntaub ntawv no tsis yog -kev sib tham tau- lawv tsim lub hauv paus ntawm S335J0WP qhov kev txheeb xyuas qhov zoo, npog cov khoom muaj pes tsawg leeg, kev ua haujlwm zoo, thiab kev tsim khoom raws li:
1. Cov Ntaub Ntawv Cov Ntaub Ntawv (MDS)
Lub luag haujlwm tseem ceeb: Muab cov lus qhia dav dav ntawm S335J0WP cov khoom tseem ceeb, ua lub hauv paus rau kev ntsuas kev ua haujlwm.
Cov Ntsiab Lus Tshawb Fawb: ① Tshuaj muaj pes tsawg leeg (yuav tsum suav nrog Cu / Cr / P- tseem ceeb rau huab cua tsis kam); ② Cov khoom siv hluav taws xob (yield zog ~ 235-335MPa, tensile zog, elongation Ntau dua lossis sib npaug li 20%, 20℃cuam tshuam lub zog Ntau dua lossis sib npaug rau 27J rau qib "J0"); ③ Kev xa khoom (piv txwv li, thermo-khoov "P", kub- dov "HR"); ④ Cov qib zoo thiab cov qauv siv tau (txawm tias tsis yog-EN 10025-5, nws yuav tsum hais txog cov qauv ntawm European steel).
2. EN 10204 Hom 3.1 Mill Test Report (MTR)
Lub luag haujlwm tseem ceeb: Cov ntaub ntawv pov thawj ntawm lub Hoobkas tshaj lij, muab cov ntaub ntawv pov thawj, thib peb - tog- tau lees paub cov ntaub ntawv rau txhua qhov kub ntawm S335J0WP.
Cov Ntsiab Lus Tshawb Fawb: ① Cov ntaub ntawv qhia txog kev taug qab (suab cua sov / ntau ntau, sib xws rau cov khoom siv lub cev); ② Cov ntaub ntawv xeem (cov tshuaj muaj pes tsawg leeg, lub zog tensile, yield zog, cuam tshuam toughness) txuam MDS qhov tseem ceeb (tso cai sib txawv tsawg dua lossis sib npaug li 5%); ③ Tus neeg soj ntsuam kos npe thiab tus neeg muag khoom daim ntawv pov thawj stamp (kom paub tseeb tias daim ntawv qhia tseeb); ④ Cov kev xeem (piv txwv li EN ISO 6892-1 rau kev xeem tensile, EN ISO 148-1 rau kev ntsuam xyuas cuam tshuam).
Cov ntaub ntawv ntxiv rau cov xwm txheej tshwj xeeb
Rau cov haujlwm uas yuav tsum tau muaj tshwj xeeb (xws li, vuam, qis / siab- kev pabcuam kub), thov cov ntaub ntawv ntxiv no los xyuas kom meej daim ntawv thov:
1. Welding Compatibility Certificate (yog tias yuav tsum tau vuam)
Cov ntsiab lus tseem ceeb: Paub meej tias cov khoom siv vuam siv tau sib xws (xws li ER70S-GNiCu, E7018-G) thiab pom zoo welding tsis (preheating temperature, heat input). Xyuas kom cov pob qij txha sib txuas nrog lub hauv paus hlau cov huab cua tsis kam thiab toughness.
2. Daim Ntawv Qhia Txog Kev Ua Haujlwm Tshwj Xeeb (yog tias tsim nyog)
Tsawg-Kev Pabcuam Kub (tsawg dua lossis sib npaug li -10 degree): Cov ntawv ceeb toom cuam tshuam ntawm qhov kev pab cuam tiag tiag (piv txwv li, -10 degree, -20 degree) txhawm rau txheeb xyuas qhov ductility.
Siab -Kev Pabcuam Kub (200-500 degree): Siab - qhov kub thiab txias thiab cov ntaub ntawv ntsuas kev nkag siab kom paub meej tias kev ruaj ntseg nyob rau hauv thermal raug.
Ntug hiav txwv / ntsev tsuag ib puag ncig: Cov ntaub ntawv qhia txog kev tiv thaiv corrosion (xws li, tshuaj tsuag ntsev rau ASTM B117) kom siv tau cov huab cua tiv thaiv.
3. Cov ntaub ntawv ntim & Shipping
Cov ntsiab lus tseem ceeb: suav nrog kev ntim khoom tshwj xeeb (xws li, VCI zaj duab xis wrapping, ISPM 15 pallets) thiab cov ntaub ntawv tshuaj xyuas shipping. Xyuas kom cov khoom tsis raug puas los ntawm ya raws, tshuaj tsuag ntsev, los yog kev sib tsoo thaum caij tsheb thauj mus los - tseem ceeb heev rau kev khaws cia qhov chaw ruaj khov thiab kev ua haujlwm.
Cov tswv yim tswv yim rau kev txheeb xyuas cov ntaub ntawv
Paub meej txog qhov sib xws: Hla- tshawb xyuas cov ntaub ntawv hla MDS, MTR, thiab cov ntawv tshaj tawm ntxiv (xws li, cov xov tooj cua sov, cov khoom siv tshuab) kom tsis txhob muaj qhov tsis sib xws.
Tshem tawm cov ntaub ntawv tsis tiav: Tsis kam MTRs yam tsis muaj cua sov batch traceability, unsigned reports, los yog MDS tsis muaj cov yam tseem ceeb (xws li, Cu/Cr cov ntsiab lus).
Qhia meej qhov tsis meej: Yog tias cov ntaub ntawv hais txog cov qauv tsis meej lossis cov ntaub ntawv tsis sib haum, thov kom cov neeg xa khoom muab cov lus piav qhia lossis rov- txheeb xyuas nrog cov ntaub ntawv xeem thawj.
Tsis txhob "Typo" Risks: Yog tias cov ntaub ntawv rov hais dua "S355J0WP" (qib tus qauv) es tsis yog "S335J0WP", lees paub nrog cov neeg xa khoom seb nws puas yog typo- qhov no cuam tshuam rau kev ua raws cai.
Hauv cov ntsiab lus, kev txheeb xyuas S335J0WP Corten Steel zoo xav tau cov ntaub ntawv yuav tsum tau ua (MDS, EN 10204 Hom 3.1 MTR) thiab qhov xwm txheej- cov ntaub ntawv tshwj xeeb ntxiv. Qhov tseem ceeb yog tsom rau cov ntaub ntawv sib xws, traceability, thiab kev sib raug zoo nrog cov kev xav tau ntawm qhov project. Los ntawm kev tshuaj xyuas cov ntaub ntawv no nruj me ntsis, cov neeg yuav khoom tuaj yeem txo qhov kev pheej hmoo ntawm cov tsis yog - cov qib txheem thiab xyuas kom cov khoom ua tau raws li qhov xav tau ntawm kev ua haujlwm. Yog tias cov neeg muag khoom tsis kam muab cov ntaub ntawv ua tiav, txheeb xyuas tau, xav txog lwm cov txheej txheem Corten Steel (xws li, S355J0WP) kom tsis txhob muaj qhov tsis zoo.
