Loj hexagonal taub hau qauv bolts ASTM A 325 / ASTM A 490

1.Dab tsi yog bolts rauloj hexagonal taub hau qauv?

Bolts nrog loj hexagonal taub hau yog fasteners siv rau kev sib txuas high-strength steel qauv. Nws lub taub hau yog cov duab loj hexagonal uas tuaj yeem tiv taus lub zog tensile thiab shear rog. Lawv tuaj yeem muab kev sib txuas kom ruaj ntseg thiab txhim khu kev qha, yog li lawv tau siv dav hauv cov txuas hniav, cov tsev, kev tsheb ciav hlau, txoj kev loj, thiab lwm yam haujlwm loj.

2.Dab tsi yog qhov txawv ntawmASTM A 325 Cov Lus Qhia Tshwj Xeebthiab ASTM A490?

ASTM A325 thiab ASTM A490 yog ob qho tib si tus qauv tshwj xeeb rau bolts siv hauv cov qauv loj hexagonal. Lawv txawv ntawm cov khoom siv zog. ASTM A325 feem ntau yog siv rau nruab nrab lub zog cov qauv, thaum ASTM A490 yog siv rau cov qauv loj, hnyav heev.

A325 bolts yog tsim los ntawm TYPE1 thiab TYPE3. TYPE1 yog siv rau cov qauv dav dav thiab tuaj yeem ua Kub-dip galvanization yog tias tsim nyog. Huab cua resistant steel yuav tsum tau siv ua ke nrog TYPE3 bolts, uas yuav tsum tau tshwj xeeb cim rau ntawm daim duab tsim thaum TYPE3 bolts siv.

Cov khoom siv zog ntawm A490 ntsia liaj qhov rooj yog siab dua A325, tab sis A490 ntsia liaj qhov rooj tsis tuaj yeem yog Kub-dip galvanization. A490 bolts tau muab faib ua peb hom TYPE3 hom bolts nrog tib huab cua hlau.A325 thiab A490 boltsmuaj cov qauv diameters hauv ko taw thiab nce ntxiv ntawm 1/8 ko taw, ob qho tib si ntawm 1 ko taw thiab 1.5 ko taw, nrog txoj kab uas hla ntawm 1 ko taw tau siv ntau dua.

3.ASME B18.2.6-2010 yog dab tsi?

ASME B18.2.6-2010 yog tus qauv Asmeskas uas qhia txog qhov yuav tsum tau muaj rau qhov ntev, cov khoom siv, cov khoom siv kho tshuab thiab tshuaj lom neeg, kev tsim khoom, thiab kev kos cov bolts rau lub taub hau loj hexagonal.

4.Qhov kev ua haujlwm ntawm bolts rau loj hexagonal taub hau qauv yog dab tsi?

Lub luag haujlwm tseem ceeb ntawm bolts siv nyob rau hauv cov qauv loj hexagonal lub taub hau yog los txuas ntau qhov sib txawv ntawm cov qauv hlau, ua rau cov khoom siv tag nrho. Lawv tuaj yeem tiv taus lub zog siab thiab muaj zog seismic thiab cua tsis kam. Yog li ntawd, bolts rau loj hexagonal taub hau qauv yog ib yam tseem ceeb ntawm fastener nyob rau hauv kev tsim kho engineering.
