Thaum yuav Q415NH Corten Steel, ntau tus neeg yuav khoom tsis lees paub cov ntaub ntawv zoo tsim nyog- qhov kev saib xyuas no tuaj yeem ua rau tau txais cov khoom lag luam uas tsis ua raws li GB / T cov qauv, kev soj ntsuam tsis tiav, lossis tseem cuam tshuam txog kev nyab xeeb ntawm cov qauv. Raws li qhov nruab nrab - huab cua muaj zog- cov hlau tsis muaj zog, Q415NH qhov zoo yuav tsum raug txheeb xyuas los ntawm cov ntaub ntawv raug cai, tab sis qhov twg yog qhov tseem ceeb, thiab lawv ua pov thawj dab tsi? Tsis zoo li cov khoom siv hlau zoo tib yam, Q415NH xav tau cov ntaub ntawv tshwj xeeb kom paub meej tias nws cov khoom siv kho tshuab thiab corrosion kuj. Lub ntsiab lus teb yog qhov tseeb:Plaub cov ntaub ntawv zoo tshaj plaws yog xav tau rau Q415NH kev yuav khoom-Mill Test Certificate, Material Certificate, Inspection Report, and Compliance Certificate-txhua tus ua kom cov hlau ua tau raws li koj qhov project qhov kev xav tau zoo. Hauv qab no yog cov lus qhia yooj yim, ua tau zoo.
Cov ntaub ntawv tseem ceeb zoo (yuav tsum tau yuav)
Cov ntaub ntawv no tsis yog - sib tham tau - lawv tshawb xyuas Q415NH qhov zoo, ua raws, thiab tsim nyog rau koj qhov project:
1. Mill Test Certificate (MTC) – Cov ntaub ntawv tseem ceeb tshaj plaws
Lub hom phiaj: Tshaj tawm los ntawm cov hlau zeb, nws ua pov thawj Q415NH batch ua tau raws li GB / T 4171 tus qauv (tus qauv tseem ceeb rau Corten Steel).
Cov ntsiab lus tseem ceeb: Cov tshuaj muaj pes tsawg leeg (Cu, Cr, Ni cov ntsiab lus los xyuas kom muaj kev tiv thaiv corrosion), cov khoom siv hluav taws xob (yield zog ntau dua lossis sib npaug ntawm 415MPa, tensile zog, elongation), thiab batch tooj (rau traceability).
2. Cov ntaub ntawv pov thawj
Lub Hom Phiaj: Txheeb xyuas cov ntaub ntawv tus kheej- paub tseeb tias nws yog Q415NH Corten Steel, tsis yog qib qis dua - qib hloov pauv (xws li Q355NH).
Cov ntsiab lus tseem ceeb: qib khoom, hnub tsim khoom, lub npe zeb, thiab thickness / loj specifications ntawm cov hlau yuav.
3. Daim ntawv tshuaj ntsuam xyuas
Lub Hom Phiaj: Cov ntaub ntawv steel qhov zoo ntawm qhov chaw thiab qhov tseeb qhov tseeb, kom ntseeg tau tias nws tsis muaj qhov tsis xws luag uas cuam tshuam rau kev ua haujlwm.
Cov ntsiab lus tseem ceeb: Kev tshuaj xyuas saum npoo av (tsis muaj kab nrib pleb, xeb, lossis khawb), thickness kam rau ua (± 1% tus qauv), thiab xyuas kom tiaj tus.
4. Daim Ntawv Pov Thawj Ua Raws Cai
Lub Hom Phiaj: Paub meej tias Q415NH ua raws li cov qauv kev lag luam uas cuam tshuam (GB/T 4171) thiab lwm yam kev xav tau ntxiv (piv txwv li, qis-kub toughness).
Cov ntsiab lus tseem ceeb: Nqe lus hais txog kev ua raws cai, kev tshaj tawm txoj cai (thib peb-party lossis mill quality department), thiab kos npe / foob rau kev siv tau.
Cov ntaub ntawv xaiv tau (raws li qhov xav tau ntawm qhov project)
Thov cov no tsuas yog tias koj qhov project muaj cov cai tshwj xeeb:
Welding Procedure Specification (WPS): Yog tias cov hlau yuav raug welded, cov ntaub ntawv no muab cov kev sib tw vuam tsis sib xws.
Thib peb- Daim Ntawv Qhia Txog Kev Xeem Xeem: Rau siab- tej yaam num tseem ceeb, ib daim ntawv qhia los ntawm ib lub chaw soj nstuam ywj pheej txheeb xyuas MTC cov ntaub ntawv (piv txwv li, kev ntsuam xyuas corrosion).
Cov tswv yim tswv yim rau cov neeg yuav khoom
Thov cov ntaub ntawv ua ntej xa khoom: Tsis txhob txais cov hlau tsis muaj ntaub ntawv - tsis lees txais cov khoom tsis muaj ntaub ntawv yuav tsum tau ua.
Txheeb xyuas cov khoom sib xws: Xyuas kom cov batch naj npawb ntawm cov ntaub ntawv sib tw rau ib qho cim ntawm daim hlau / coils.
Tsom ntsoov rau cov ntaub ntawv tseem ceeb: Txheeb xyuas MTC cov khoom siv tshuaj thiab cov khoom siv sib xyaw ua ke nrog Q415NH tus qauv (xws li, tawm lub zog ntau dua lossis sib npaug rau 415MPa).
Hauv cov ntsiab lus, plaub cov ntaub ntawv uas yuav tsum tau ua zoo (MTC, Cov Khoom Siv Ntawv Pov Thawj, Daim Ntawv Qhia Tshuaj Xyuas, Daim Ntawv Pov Thawj Ua Raws Cai) yog qhov tseem ceeb rau Q415NH kev yuav khoom. Lawv tiv thaiv koj los ntawm cov khoom siv tsis tau zoo, xyuas kom ua raws li cov qauv, thiab muab cov ntaub ntawv taug qab - tseem ceeb rau kev nyab xeeb, txhim khu kev qha cov txiaj ntsig.
