ASTM A501 yog dab tsi?

 

Qhov kev qhia tshwj xeeb no suav nrog cov xim dub thiab kub -dipped galvanized kub- tsim welded thiab seamless carbon steel square, puag ncig, duab plaub, los yog tshwj xeeb cov qauv tubing rau welded, riveted, los yog bolted kev tsim kho ntawm cov choj thiab cov tsev, thiab rau cov qauv siv dav dav.
 
  • Qib ntawm cov tubing yogQib A, Qib B, thiabQib C.
 
  • Kev tsim cov duab kawg yuav tsum tau ua los ntawm cov txheej txheem kub txheej txheem

 

  • Lub vuam yuav tsum tsis txhob nyob rau hauv lub vojvoog ntawm cov ces kaum ntawm ib lub raj uas muaj ib los yog ntau lub tiaj tiaj.

 

  • Nws yuav tsum tau tso cai ntxiv rau normalizingKev kho cua sovrau tubing nrog phab ntsa thickness ntau dua 1/2 hauv.[13 mm].
