AS3679 STEEL PIPES

AS3679 yog qhov tshwj xeeb rau kub-rolled steel rau kev siv cov qauv hauv Australian, npog ntau hom phiaj hlau, suav nrog cov phiaj hlau, cov kab hlau thiab cov kav hlau sib tshooj. Cov qauv no qhia meej txog kev ua tau xws li cov tshuaj chemical, thiab yog siv rau cov ntawv thov ua haujlwm hauv liaj teb xws li kev tsim kho, txuas hniav, thiab kho tshuab tsim. Hauv qab no yog cov ntaub ntawv tseem ceeb ntawm AS3679 Steel Yeeb:

AS3679 Caws classifies cov hlau hlau mus rau ntau hom muaj zog. Cov qauv siv hluav taws xob txawv xws li:

• Raws li 3679-250}: tensile lub zog ntawm 250 MPA qib ntawm 250 MPA qib, nrog cov ntsej muag zoo thiab weldability, haum rau cov qauv dav.

• Raws li 3679-300}: tensile lub zog ntawm 300 Mpa, lub zog nruab nrab, muaj zog hauv kev tsim cov thav ntawv thiab cov qauv kev txhawb nqa.

• Raws li 3679-350}: tensile lub zog ntawm 350 MPA lub zog ntawm 350 MPA muaj zog thiab cov huab cua zoo, haum rau cov haujlwm hnyav lossis qhib ib puag ncig.

Cov kev cai tshwj xeeb rau txhua qib muaj:
• Cov tshuaj lom neeg tshuaj: cov ntsiab lus txwv ntawm cov pa roj carbon monanpon (c), manganese (mn), leej faj (p).

• Cov yam ntxwv txhua yam: tawm lub zog, elongation, thiab lwm yam, cov paib muaj zog ntawm li} yog ntau dua lossis sib npaug zos rau 350 mpa).

• Kev tsim kho tsim: siv rau cov qauv hlau, lub ru tsev trusses, txhua yam, thiab lwm yam.

• Page Engineering: Kev tsim khoom thauj khoom-cov kabmob xws li choj Piers thiab txhawb tws.

• Kev tsim kho txhua yam: ua tus qauv txhawb nqa lossis kev sib kis kev sib kis lossis kev sib kis rau cov khoom siv kho tshuab.

• Infrastructure: cov yeeb nkab txhawb nqa, xa cov yees, thiab lwm yam.

• Weldability: As \/ NZS 1554 vuam txheem yuav tsum tau ua, thiab sib txuam vuam cov ntaub ntawv thiab cov txheej txheem xaiv.

• Txiav thiab kev sib sau ua: txias dabtsi yog khoov, kub khoov thiab lwm yam kev ua tau. Nws yog ib qho tsim nyog los them sai sai kom tsis txhob muaj cov khoom embrittlement.

• Cov kev kho deg: txheej lossis kub-dip galvanizing (xws li AS \/ NZS 4680) yuav tsum tau txhim kho corrosion tsis kam.

• Sib piv nrog Astm: Raws li 3679-350 zoo sib xws rau ASTM A572 Qib 50, tab sis muaj tej zaum yuav muaj cov tshuaj lom neeg thiab cov qauv kev sim.

• Piv nrog rau tus qauv En: Raws li 3679-350 yog ze rau S355 steel ntawm European cov qauv en}, tab sis saib xyuas yuav tsum tau them rau cov ntawv pov thawj thiab cov kev cai tshwj xeeb hauv cheeb tsam.

• Kev ntsuas cov xwm txheej: rau cov khoom siv hluav taws xob ntau lossis kev poob siab ib puag ncig, nws pom zoo kom xaiv raws li 3679-350.

• Ib puag ncig cov xwm txheej: Kev pab tiv thaiv sab saum npoo yuav tsum tau ua nyob rau hauv cov chaw noo lossis kev xeb lossis ib puag ncig corrosive.

• Kev lag luam: Qhov li 3679-250 muaj tus nqi qis thiab haum rau cov qauv tsis yog tus qauv tseem ceeb.

Daim ntawv pov thawj yuav tsum muaj: Thaum yuav khoom, nws yog ib qho tsim nyog kom paub meej tias cov hlau ua raws li AS3679 tus qauv thiab muab cov ntawv pov thawj khoom (MTC).

• Qhov seem xav tau: Qhov kev sib txawv rau cov uas hla, phab ntsa thickness, thiab lwm yam raws li tau raug xa mus.

AS3679 Cov kav hlau hlau yog siv dav hauv kev ua lag luam engineering hauv Australia thiab thoob ntiaj teb vim lawv lub zog siab thiab paub tab. Thaum ua ib qho kev xaiv tshwj xeeb, nws pom zoo los ua kev txheeb xyuas kev sib txuas ua ke nrog kev tsim qauv engineering, cov qauv hauv zos thiab ib puag ncig cov qauv.
