Export Steel Phaj & Hlau Yeeb Nkab Tshuaj Xyuas Thiab Txais Kev Xeem

Export Steel Phaj & Hlau Yeeb Nkab Kev Tshuaj Xyuas thiab Txais Kev Xeem

Hlau daim hlau thiab cov kav hlau yog cov ntaub ntawv tseem ceeb uas tau siv dav hauv kev lag luam steel thoob ntiaj teb, kev lag luam sab nrauv, kev tsim kho vaj tse, petrochemical pipelines, cov khoom siv hluav taws xob thiab kev tsim khoom. Rau cov khoom siv hlau xa tawm, tus qauv thib peb- kev tshuaj xyuas ob tog thiab tag nrho - kev lees paub ntau yam yog qhov tseem ceeb los xyuas kom meej cov khoom sib xws, qhov tseeb, qhov zoo ntawm qhov chaw thiab cov qauv kev nyab xeeb, ua tau raws li cov kev qhia tshwj xeeb thoob ntiaj teb, kev lees paub ntawm cov neeg yuav khoom thiab cov qauv kev lis kev cai.

Peb cov kws tshaj lij export steel soj ntsuam kev pabcuam suav nrog tag nrho - txheej txheem kev saib xyuas lub Hoobkas, batch sampling kuaj, tiav cov khoom lees paub thiab ua ntej- kev tshuaj xyuas cov khoom xa tuaj, muab kev ntseeg tau, kev lees paub zoo thoob ntiaj teb rau cov neeg yuav khoom thoob ntiaj teb, cov neeg xa khoom thiab cov neeg ua haujlwm engineering.

1. Kev soj ntsuam tag nrho rau Export Steel Phaj & Cov kav dej

1.1 Chemical Composition Testing

Kev txheeb xyuas meej meej ntawm carbon, silicon, manganese, phosphorus, sulfur, chromium, npib tsib xee, molybdenum thiab lwm yam alloying ntsiab yog nqa tawm los xyuas cov qib steel ua raws. Nws ua kom cov khoom ua tau raws li cov qauv tsim nyog xws li ASTM, ISO, EN thiab GB, tswj cov khoom tsis zoo thiab lav qhov weldability, corrosion kuj thiab tag nrho cov khoom ruaj khov. Qhov kev xeem no yog lub hauv paus tseem ceeb rau kev lees paub qib cov khoom siv thiab kev txheeb xyuas kev lag luam zoo.

1.2 Mechanical Property Testing

Peb ua tiav cov kev ua tau zoo ntawm cov neeg kho tshuab suav nrog lub zog tensile, lub zog tawm los, elongation, txo qhov chaw, hardness (HBW, HRB, HV), thiab qis -kub / chav tsev- ntsuas qhov kub thiab txias. Cov khoom no ua kom cov ntawv hlau thiab cov kav dej ua kom muaj peev xwm ua tau raws li qhov muaj peev xwm, seismic tsis kam, qis -kub toughness thiab mechanical kev pabcuam rau kev tsim kho txawv teb chaws, cov kav dej xa mus thiab cov khoom siv kho tshuab.

1.3 Dimensional & Appearance Inspection

Kev soj ntsuam tag nrho qhov ntev ntawm qhov kev tiv thaiv npog npog tuab, dav, qhov ntev, sab nraud txoj kab uas hla, phab ntsa thickness, ncaj thiab flatness kom tshem tawm tawm - ntawm - cov khoom kam rau ua. Kev soj ntsuam nruj nreem kuaj pom khawb, dents, dov cov kab nrib pleb, oxidation tsis xws luag, delamination thiab txheej tsis xws luag, kom ntseeg tau tias tag nrho cov khoom tiav ua tau raws li kev xa tawm - qib tsos thiab cov qauv ntsuas.

1.4 Tsis yog-Kev Ntsuam Xyuas Kev Puas Tsuaj (NDT)

Kev tshuaj xyuas tag nrho NDT yog muaj rau cov hlau phaj thiab seamless / welded steel kav. Ultrasonic Testing (UT) kuaj pom sab hauv delamination, suav nrog thiab tawg hauv daim hlau thiab cov yeeb nkab lub cev. Radiographic Testing (RT) ntsuas qhov zoo ntawm cov kav dej welded. Sib Nqus Particle (MT) thiab Penetrant Testing (PT) txheeb xyuas qhov tsis xws luag ntawm qhov chaw. NDT ua kom xoom txaus ntshai qhov tsis xws luag hauv cov khoom siv hlau xa tawm ua ntej xa khoom.

1.5 Kev Ntsuas Tshwj Xeeb

Raws li cov kev xav tau ntawm kev ua haujlwm txawv teb chaws, peb muab ntsev tsuag tshuaj tiv thaiv corrosion, huab cua tsis kam, intergranular corrosion, hydrostatic siab kuaj, flaring, flattening thiab dabtsi yog khoov kuaj, los xyuas kom meej qhov kev pab cuam stability ntawm steel kav thiab daim hlau nyob rau hauv marine, tshuaj, siab -siab thiab huab{1}} kub ua hauj lwm tej yam kev mob.

2. International Standards Ua raws li

Tag nrho cov txheej txheem xeem thiab kev ntsuam xyuas tau nruj me ntsis raws li thoob ntiaj teb cov ntsiab lus tshwj xeeb:

ASTM International Standards

ISO International Organization for Standardization

EN Cov Qauv European

Suav GB Standards (rau cross-reference verification)

Tag nrho cov ntaub ntawv kawg yogCMA/CNAS tau lees paub, lees paub tag nrho los ntawm cov neeg yuav khoom txawv teb chaws, cov tuam txhab saib xyuas engineering, kev lis kev cai thiab thib peb - tog kev txiav txim siab.

3. Cov Txheej Txheem Kev Pabcuam rau Kev Tshawb Fawb Export
