ASTM A285 Gulu A Boiler zitsulo mbale

Muyezo wa ASTM A285 ndi wachitsulo cha kaboni, mbale zachitsulo zotsika komanso zapakatikati zomwe zimapangidwira zombo zophatikizika.

Chitsulo chachitsulo pansi pa ASTM A285 chimakhala m'makalasi atatu, A, B ndi C, omwe amagwiritsidwa ntchito kwambiri ndi ASTM A285 Grade C mbale.
Zomwe ziyenera kupangidwa ndi zida zophedwa, zophedwa pang'ono, zotsekera kapena zitsulo zokhala ndi mipiringidzo posankha wopanga.

makulidwe: 6mm mpaka 300MM,
m'lifupi: 1500mm kuti 4050mm,
Utali: 3000mm kuti 15000mm

A285 giredi A Chemical Composition

Zolemba Zotsatiridwa:

ASTM Sandards:

A20/A20M: Zofunikira zonse za mbale zachitsulo zotengera zokakamiza.

Zofunikira Zonse ndi Zambiri Zoyitanitsa:

Kuyesa ndi kuyesanso njira, njira, kulolerana kwa kukula, misa, khalidwe ndi kukonza zolakwika, kuyika chizindikiro, kutsitsa ndi kuyitanitsa zidziwitso ziyenera kutsatira A20/A20M.
Kuphatikiza pazofunikira, zofunikira zina zowonjezera zilipo.
Ma coils amachotsedwa ku A285 mpaka atadulidwa kukhala mbale.
