Daim ntawv pov thawj MTC rau Stainless Hlau Yeeb Nkab yog dab tsi? Qhov twg yog qhov tseem ceeb siv?

Daim ntawv pov thawj MTC yog dab tsi: EU MTC daim ntawv pov thawj tseem hu ua EN 10204 daim ntawv pov thawj, cov ntaub ntawv pov thawj siab, daim ntawv pov thawj cov ntaub ntawv pov thawj, cov ntaub ntawv xeem cov ntaub ntawv, thiab lub npe tag nrho yog: "Manufactory Test Certificate", uas yog ib daim ntawv pov thawj ntawm cov khoom siv tshuaj lom neeg, kev siv tshuab thiab lub cev. Cov ncauj lus kom ntxaws txog cov txheej txheem tsim khoom, tshuaj lom neeg muaj pes tsawg leeg, cov khoom siv lub cev thiab cov khoom siv kho tshuab feem ntau yog muab los xyuas kom meej tias cov ntaub ntawv muab tau raws li cov qauv thiab cov lus qhia tshwj xeeb.

 

Daim ntawv pov thawj MTC yog ib daim ntawv pov thawj tseem ceeb uas muab kev lees paub kev ua raws cai rau koj cov khoom hlau xa tawm.

Qee qhov yuav tsum tau ua rau MTC daim ntawv pov thawj suav nrog:

1. Cov ntaub ntawv piav qhia: Daim ntawv pov thawj MTC yuav tsum muaj cov lus piav qhia meej ntawm cov khoom xa tuaj, suav nrog lub npe, qhov tshwj xeeb, ntau thiab lwm yam ntaub ntawv ntawm cov khoom.

2. Cov khoom siv: Daim ntawv pov thawj yuav tsum muab cov ntaub ntawv ntawm cov khoom ntawm cov khoom, xws li tshuaj lom neeg muaj pes tsawg leeg, cov khoom siv lub cev, cov qauv zoo, thiab lwm yam.

3. Kev tuav thiab ntim khoom: Yog tias tsim nyog, daim ntawv pov thawj yuav xav tau cov ntaub ntawv ntawm kev tuav thiab ntim khoom kom ntseeg tau tias kev tuav thiab kev thauj khoom zoo.

4. Kev ua raws li cov khoom siv: Daim ntawv pov thawj yuav xav tau cov lus qhia txog kev ua raws li cov khoom siv, xws li kev ua raws li cov kev cai tshwj xeeb, cov qauv lossis cov kev xav tau ntawm kev lag luam.

 

MTC daim ntawv pov thawj rau seamless stainless hlau kav

Cov khoom kuaj tseem ceeb: MTC cov khoom kuaj tseem ceeb yog: tshuaj muaj pes tsawg leeg, lub zog tensile, hardness thiab cuam tshuam. Cov ntsiab lus xeem tshwj xeeb yuav tsum tau txiav txim siab raws li cov qauv khoom siv.

 

EN 10204 MTC Hom: Hom 3.1 vs. Hom 3.2

Thaum muab cov kav dej stainless hlau, cov khoom siv tshwj xeeb yuav ua kom meej meej rau EN 10204 daim ntawv pov thawj hom:

EN 10204 Hom	Tso Cai	Independent Verification	Yam Kev Lag Luam Yuav Tsum Tau
Hom 2.1 / 2.2	Chaw tsim tshuaj paus	Tsis muaj (Tsis yog- kev sim tshwj xeeb)	Tsawg-kev pheej hmoo ntawm cov qauv tubing
Hom 3.1	Chaw tsim tshuaj paus kev ywj pheej QA tshuaj xyuas	Hauv - tsev ntawv pov thawj QA (Independent of production department)	Standard industrial piping, HVAC, zaub mov / dej haus, cov kab dav dav
Hom 3.2	Chaw tsim tshuaj paus QA + Tso Cai 3rd Party (piv txwv li, TUV, SGS, BV, Lloyd's Register)	Independent 3rd Party soj ntsuam thiab kuaj ua tim khawv	Siab - siab roj & roj pipelines, nuclear nroj tsuag, offshore marine systems

 

Qhov twg yog Stainless Hlau Yeeb Nkab MTC Siv Tau?

MTC yog ib qho yuav tsum muaj kev nyab xeeb thiab ua raws li cov ntaub ntawv hla ntau qhov kev lag luam tseem ceeb:
Roj & Gas (Upstream thiab Downstream): Txheeb xyuas tias cov qib yeeb nkab (xws li 316L, Duplex 2205, Super Duplex 2507) tuaj yeem tiv taus roj qaub (H2S), kev kub siab, thiab corrosive marine ib puag ncig.
Chemical thiab Petrochemical Ua: Ua kom muaj cov tshuaj lom neeg muaj pes tsawg leeg raws li cov lus qhia tshwj xeeb, yog li tiv thaiv cov teeb meem xws li intergranular corrosion, pitting, thiab kev puas tsuaj rau cov yeeb nkab phab ntsa tsis ua hauj lwm thaum lub sij hawm tshuaj synthesis.
Pharmaceutical and Food Processing: Xyuas kom meej tias cov kav dej huv huv - qib piping (ASTM A270/A269) ua tau raws li cov qauv ntawm cov khoom siv purity, hnyav hlau txwv, thiab nto roughness (Ra tsawg dua lossis sib npaug li 0.4 µm).
Kev Tsim Hluav Taws Xob thiab Boiler Manufacturing: Ua kom muaj cua sov- cov qib steel resistant (piv txwv li, 321, 310S, 347H) ua tau raws li qhov yuav tsum tau muaj zog rupture thiab siab - kub siab lub nkoj lis dej num (ASME Tshooj VIII).
EPC Cov Haujlwm thiab Kev Tshawb Fawb: Cov tswv lag luam, cov ntawv pov hwm, thiab cov neeg saib xyuas kev tswj hwm xav tau cov ntaub ntawv no ua ntej kev teeb tsa cov kav dej.

 

Kev Tswj Xyuas Kev Ua Haujlwm Zoo: Yuav Ua Li Cas Txheeb Xyuas Cov Ntawv Pov Thawj (MTC)

Txhawm rau txo cov kev pheej hmoo cuam tshuam nrog cov kav hlau tsis muaj steel hlau, pawg neeg yuav khoom yuav tsum ua raws li plaub kauj ruam pov thawj no:
1. Txheeb xyuas tus naj npawb Thaum tshav kub kub: Lub cev sib piv cov cua sov uas cim (ntawm inkjet lossis laser) ntawm cov yeeb nkab nto nrog cov cua sov uas tau sau rau ntawm MTC.
2. Cross-check Chemical Composition Limits: Confirm that the content of each element meets standard limit requirements (e.g., for 316L/1.4404 grade steel, nickel content must be >10.0% thiab cov ntsiab lus carbon tsawg dua lossis sib npaug li 0.030%).
3. Ua Haujlwm Ntawm -Kev Xeem PMI ntawm qhov chaw: Thaum tuaj txog ntawm cov khoom, ua cov khoom pov thawj zoo (PMI) siv lub xov tooj ntawm tes XRF ntsuas kom paub meej tias cov khoom muaj pes tsawg leeg sib phim cov ntaub ntawv pov thawj.
4. Txheeb xyuas Mill Markings: Tshawb xyuas lub zeb zeb cov ntaub ntawv pov thawj zoo (QA) thwj, tus neeg soj ntsuam kos npe, thiab cov lej QR lossis cov ntawv txuas (yog tias tsim nyog).

 

FAQ

Q1: Dab tsi yog qhov txawv ntawm MTC, MTR, thiab Daim Ntawv Pov Thawj Zeb?
Teb: Tsis muaj qhov sib txawv ntawm qhov ua tau zoo. MTC (Mill Test Certificate), MTR (Mill Test Report), thiab Mill Certificate xa mus rau tib daim ntawv txheeb xyuas cov tshuaj lom neeg, khoom siv, thiab kev sim ntawm cov hlau tshwj xeeb.

 

Q2: Cov yeeb nkab steel hlau puas tuaj yeem raug ntsia lossis ua haujlwm yam tsis muaj MTC?
Teb: Hauv kev tswj hwm kev lag luam (xws li cov cuab yeej siv siab raws li PED 2014/68 / EU, ASME piping, lossis cov chaw siv roj thiab roj), kev teeb tsa tsis muaj MTC raug txwv nruj heev. Cov kav dej uas tsis muaj ntawv pov thawj tam sim no muaj kev phom sij loj heev thiab yuav ua tsis tau thib peb - tog neeg soj ntsuam kev tswj hwm.

 

Q3: Kuv yuav ua li cas yog tias tus xov tooj cua sov ntawm cov yeeb nkab tsis sib haum nrog MTC?
Teb: Quarantine cov yeeb nkab xa khoom tam sim ntawd. Cov xov tooj cua sov tsis sib haum txhais tau tias poob ntawm cov khoom siv traceability. Thov ib daim ntawv qhia meej tam sim ntawd, thov qhov thib peb -chaw kuaj mob kuaj xyuas- kev tshuaj xyuas, lossis tsis lees txais ntau yam los tiv thaiv kev txhim kho cov khoom tsis tau lees paub.
