A500 Hollow Structural Steel (HSS) Tubing piav qhia
Hollow Structural Section (HSS) ntawm A500 yog carbon steel hollow structural profile raws li ASTM A500 cov qauv, tsim tshwj xeeb rau cov qauv kev pab cuam daim ntawv thov nyob rau hauv lub tsev, engineering, thiab manufacturing industries. Hauv qab no yog cov ntsiab lus ntawm nws cov yam ntxwv tseem ceeb thiab kev siv:
Txhais thiab Zoo:
Hollow structural sections yog hollow sab hauv, nrog cross-sections feem ntau ncig, square, los yog rectangular. Qhov kev tsim no txo cov khoom siv thaum tuav lub zog.
Ua raws li ASTM A500 tus qauv, uas qhia meej txog qhov yuav tsum tau muaj rau qhov ntev, cov duab, qhov hnyav, tshuaj lom neeg muaj pes tsawg leeg, thiab cov khoom siv hluav taws xob ntawm cov khoom txias - tsim cov welded thiab seamless carbon steel qauv seem.
Khoom siv:
Ua los ntawm cov pa roj carbon steel, nws muaj lub zog zoo, nruj, thiab kav ntev.
Kev kho deg xws li kub -dip galvanizing tuaj yeem siv los txhim kho corrosion thiab hloov mus rau ntau yam ib puag ncig.
