ASTM A500 Qib A Cov Qauv Yeeb Nkab Qhia
ASTM A500 yog tus qauv tsim los ntawm American Society for Testing and Materials (ASTM) rau txias- ua welded thiab seamless carbon steel structural tubing. Qib A (GRA) yog ib theem nyob rau hauv ASTM A500 tus qauv, qhia qhov tsawg kawg nkaus tensile lub zog, qhov tsawg kawg nkaus yield zog, thiab lwm yam khoom vaj tse yuav tsum tau rau cov qauv tubing.
Daim ntawv thov:
Hauv kev tsim kho kev lag luam, A500 GRA structural tubing feem ntau yog siv los tsim cov thav duab, txhawb cov qauv, ru tsev trusses, thiab lwm yam.
Hauv kev tsim choj, nws tuaj yeem siv rau cov piers, kab teeb, thiab lwm yam khoom siv.
Nyob rau hauv kev lag luam machinery manufacturing, cov qauv tubing no tuaj yeem siv los tsim cov tshuab thav duab, txhawb cov qauv, thiab lwm yam khoom siv tshuab.

Cov txheej txheem tsim khoom ntawm A500 GRA cov qauv tubing feem ntau suav nrog cov kauj ruam tseem ceeb hauv qab no:
Raw khoom npaj: Xaiv cov khoom tsim nyog carbon steel thiab ua ntej - kho lawv (piv txwv li, tshem tawm qhov tsis xws luag, txiav kom ntev) rau kev tsim tom ntej.
Txoj kev tsim: Rau welded tubing, curl steel daim hlau / strips rau hauv cov duab thiab vuam npoo; rau seamless tubing, tsim tubing ncaj qha los ntawm billets ntawm piercing dov los yog extrusion.
Kev kho cua sov: Kho cov tubing tsim kom tshem tawm cov kev ntxhov siab sab hauv, txhim kho microstructure, thiab txhim kho cov khoom siv kho tshuab.
Tiav thiab tshuaj xyuas: Ua kom tiav cov raj (piv txwv li, straightening, txiav, sib tsoo) kom tau raws li qhov loj me thiab cov qauv saum npoo, thiab ua tib zoo tshuaj xyuas thiab kev ntsuam xyuas kom ua tau raws li ASTM A500 Qib A.
