ASTM A333 Tsawg Kub Qib 6 Hlau Yeeb Nkab

ASTM A333 Tsawg Kub Qib 6 Hlau Yeeb Nkab piav qhia

A333Gr.6 qis-kub seamless yeeb nkab belongs rau qeb ntawm qis-kub seamless steel kav. Lub ntsiab daim ntawv thov ntawm cov hlau no yog ntxuav, purification, desulfurization thiab degreasing ntau lawm cov cuab yeej nyob rau hauv zus tau tej cov ethylene, propylene, urea, hluavtaws ammonia, nitrogen, phosphorus thiab poov tshuaj chiv thiab tshuaj industries siv roj av, tshuaj, natural gas thiab thee raws li raw cov ntaub ntawv, raws li zoo raws li cov khoom siv txias txias {5}. cov kav xa dej rau thauj ultra- cov roj kub liquefied gases thiab lawv cov kav dej.

ASTM A333 Gr . 6 tshuaj muaj pes tsawg leeg:

ASTM A333 Gr. 6 cov cuab yeej cuab tam:

Charpy V-notch (CVN) cuam tshuam kev ntsuas rau A333 GR.6 steel yeeb nkab yog lub hauv paus tseem ceeb hauv kev txheeb xyuas nws qhov qis- qhov kub thiab txias. Cov hauv qab no yog cov ncauj lus kom ntxaws ntawm qhov kev xeem:

1. Cov qauv ntsuas thiab cov kev xav tau

Cov qauv: ASTM A333 / ASME SA333 (tuaj yeem qhia meej txog cov kev xav tau ua haujlwm rau qis-kub steel).

Kev ntsuas kub: -50℃F (-45 degree) (tus qauv yuav tsum tau muaj; qhov ntsuas kub qis dua tuaj yeem pom zoo sib cais rau cov haujlwm tshwj xeeb).

Test Direction: Sampling feem ntau yog ua raws txoj kab ntev (L kev taw qhia) ntawm cov yeeb nkab steel kom muaj kev cuam tshuam qhov kev ntxhov siab ntawm lub raj xa dej.

2. Kev Npaj Cov Qauv

Sampling Qhov Chaw: Sampling yog muab los ntawm cov yeeb nkab lub cev los yog ze ntawm qhov vuam (yog tias ntsuas qhov cuam tshuam ntawm vuam). Qhov chaw tshwj xeeb yog txiav txim los ntawm tus qauv lossis daim ntawv cog lus.

Specimen Size: Tus qauv Charpy V-notch specimen loj yog 10mm × 10mm × 55mm (10mm square cross-section, 55mm ntev), nrog V-zoo li tus notch (45℃kaum sab xis, 0.25mm hauv paus vojvoog).

Notch Direction: Cov axis axis yog perpendicular mus rau steel yeeb nkab nto, simulating qhov cuam tshuam kev taw qhia cov yeeb nkab yuav ntsib.

3. Cov txheej txheem xeem

Kev Tswjhwm Kub: Txias cov qauv mus rau -50℃F (-45 degree) thiab tuav lub sijhawm txaus (feem ntau Ntau dua lossis sib npaug li 30 feeb) kom ntseeg tau tias tag nrho cov qauv mus txog qhov ntsuas kub.

Impact Energy: Siv lub pendulum impact testing machine to impact the specimen at a specific speed (e.g., 5m/s), and record the energy absorbed when the specimen fractures (unit: J or ft·lbf).

Tus naj npawb ntawm Kev Ntsuas: Feem ntau, 3 cov qauv raug kuaj rau ib pawg ntawm cov kav hlau, thiab qhov nruab nrab tus nqi raug coj mus kuaj.

4. Kev lees txais

Yam tsawg kawg nkaus absorbed zog:

Tib Cov Qauv: Ntau dua lossis sib npaug rau 20 ft·lbf (27 J) yog ib qho yuav tsum tau muaj, tab sis cov txiaj ntsig tshwj xeeb yuav tsum tau hais los ntawm kev yuav khoom los yog cov qauv tsim (qee qhov kev xav tau yuav xav tau ntau dua qhov tseem ceeb).

Tus Nqi Nruab Nrab: Qhov nruab nrab tus nqi ntawm 3 tus qauv yuav tsum tau ua kom tau raws li lossis tshaj tus nqi teev tseg.

Shear Rate: Qee cov qauv xav tau qhov kev faib ua feem ntawm qhov chaw ntawm qhov chaw tom qab cov pob txha tawg (piv txwv li, Ntau dua lossis sib npaug li 85%) txhawm rau txiav txim siab seb hom pob txha puas yog cov pob txha puas.

5. Qhov tseem ceeb ntawm Kev Xeem

Kev pov thawj ntawm Tsawg-Tsub Toughness: Xyuas kom meej tias cov yeeb nkab steel tseem muaj kev tiv thaiv txaus rau nkig tawg ntawm -50℃F (-45 degree), zam kev tsis ua hauj lwm tam sim hauv qhov chaw kub qis.

Kev Tswj Xyuas Zoo: Los ntawm kev sim batch, cov kav hlau uas ua tau raws li qhov yuav tsum tau ua rau qis - qhov kub thiab txias kev pabcuam raug xaiv los ua kom muaj kev nyab xeeb ntawm qhov project.

Tsim Qauv: Cov ntaub ntawv xeem muab qhov tseem ceeb rau qhov qis - qhov kub thiab txias tsim, xaiv cov khoom siv, thiab kev ntsuas kev nyab xeeb ntawm cov kav dej.
