Astm A131 Nkoj Lub Tsev Hlau Phaj

ASTM A131 shipbuilding steel phaj muaj cov yam ntxwv hauv qab no:

 

I. Cov qauv nruj nruj

 

Kev tswj cov tshuaj muaj pes tsawg leeg: ASTM A131 tus qauv muaj cov kev cai nruj ntawm cov tshuaj muaj pes tsawg leeg ntawm nkoj tsim steel daim hlau. Tshwj xeeb, muaj qhov txwv tsis pub muaj kev txwv rau cov ntsiab lus ntawm cov ntsiab lus xws li carbon, manganese, silicon, sulfur, thiab phosphorus kom ntseeg tau tias cov hlau phaj muaj cov khoom siv zoo thiab kev ua haujlwm vuam. Piv txwv li, kev tswj cov ntsiab lus ntawm cov pa roj carbon monoxide tuaj yeem cuam tshuam rau lub zog thiab lub zog ntawm cov phaj steel, thaum cov ntsiab lus ntawm impurity ntsiab xws li sulfur thiab phosphorus tuaj yeem cuam tshuam qhov kev ua haujlwm vuam thiab corrosion tsis kam ntawm steel phaj.

Cov cuab yeej cuab yeej cuab tam: Tus qauv no qhia txog cov cuab yeej cuab tam xws li lub zog tensile, lub zog tawm los, thiab elongation ntawm shipbuilding steel daim hlau. Kev teeb tsa ntawm cov ntsuas no yog los xyuas kom meej tias cov hlau phaj tuaj yeem tiv taus ntau yam kev ntxhov siab thiab kev thauj khoom thaum lub sij hawm siv nkoj thiab siv, yog li lav qhov kev nyab xeeb ntawm cov nkoj. Piv txwv li, lub zog tensile ntau dua ua rau cov phaj hlau tsis tshua muaj kev puas tsuaj thaum raug nro, thiab elongation zoo tso cai rau cov phaj hlau kom muaj peev xwm deformation thaum cuam tshuam, nqus lub zog thiab txo kev puas tsuaj.

 

II. Welding Performance zoo heev

 

Kev ntsuam xyuas Weldability: ASTM A131 shipbuilding steel daim hlau raug soj ntsuam nruj weldability kom ntseeg tau tias ntau txoj kev vuam siv tau rau kev sib txuas thaum lub nkoj tsim. Weldability kev ntsuam xyuas suav nrog cov kev ntsuam xyuas ntawm kev hloov pauv ntawm cov hlau phaj rau vuam txheej txheem, cov khoom siv kho tshuab thiab tawg tsis kam ntawm cov pob qij txha. Piv txwv li, los ntawm kev siv cov txheej txheem vuam tsim nyog thiab cov khoom siv vuam, nws tuaj yeem ua kom ntseeg tau tias lub zog ntawm cov welded sib koom tsis qis dua li ntawm cov hlau hauv paus thiab nws muaj qhov zoo toughness thiab corrosion kuj.

Kev cob qhia txheej txheem vuam: txhawm rau ua kom cov vuam zoo, ASTM A131 tus qauv tseem muab cov txheej txheem vuam, nrog rau cov lus qhia txog kev siv vuam, cov khoom siv vuam, thiab cov vuam tsis zoo. Cov txheej txheem no tuaj yeem pab cov tuam txhab tsim nkoj xaiv cov txheej txheem vuam tsim nyog thiab txhim kho vuam efficiency thiab zoo.

Feem ntau hais lus, cov thickness ntau ntawm nkoj tsim steel daim hlau tuaj yeem nyob ntawm ob peb millimeters mus rau ntau kaum millimeters. Piv txwv li, hauv qee lub nkoj me me lossis qhov tsis tseem ceeb ntawm cov nkoj, cov hlau nyias nyias xws li 4 millimeters thiab 6 millimeters yuav raug siv. Rau qhov tseem ceeb ntawm cov qauv ntawm lub nkoj loj, xws li lub nkoj hauv qab thiab sab, cov phaj tuab tuab xws li 20 millimeters, 30 millimeters lossis cov tuab tuab tuaj yeem siv.

Muaj cov qauv hauv teb chaws rau cov qauv thickness ntawm shipbuilding steel daim hlau. Nyob rau hauv Suav teb, lub teb chaws tus qauv rau shipbuilding steel daim hlau yog feem ntau GB/T 712-2011 "Structural Steels rau nkoj thiab Offshore Structures".

 

Cov qauv no qhia cov qib, tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, cov khoom xa tuaj, qhov ntau thiab tsawg, cov duab, qhov hnyav thiab qhov sib txawv ntawm qhov kev tso cai, cov kev xav tau, kev sim, kev soj ntsuam cov cai thiab lwm cov ntsiab lus ntawm cov qauv hlau rau cov nkoj thiab cov qauv sab nrauv.
