ASTM A387 Gr11 CL2N Container Steel Plate, Alloy Steel plate
1. Kufotokozera Mosavuta:
1) ASTM Standard A387/A387M-11 Chromium-Molybdenum Alloy Steel Sheets for Pressure Vessels Chemical Composition
Kutentha kwa Impact Kutumiza Kwachizolowezi + Kutentha / Kutsekedwa.
2) Giredi iliyonse excepi Magiredi 21L 22L ndi 9 akupezeka ma inlasses a milingo yamphamvu yamphamvu monga momwe tafotokozera mu matebulo a Tensile Requirements.
Magiredi 21L ndi 22L akupezeka kokha ngati Class 1 Grade 91 ikupezeka kokha ngati Class 2. NOTE 1- Grade 911, yomwe inalipo kale ndi izi.
mafotokozedwe, tsopano ali ndi Specification A1017/A1017M.
3) Kuchuluka kwa makulidwe a mbale kumachepetsedwa ndi kuchuluka kwa kapangidwe kake kuti zikwaniritse zofunikira zamakina zamakina.

4. Chiwonetsero chazithunzi:
5. Kutumiza:
6. Chotengera Kutsegula:
7. Kugwiritsa ntchito:
Cholinga chachikulu cha mbale ya American standard chidebe: yomwe imagwiritsidwa ntchito kwambiri mumafuta, mankhwala, malo opangira magetsi, boiler ndi mafakitale ena,
zomwe zimagwiritsidwa ntchito kupanga ma reactor, zosinthira kutentha, zolekanitsa, matanki ozungulira, matanki amafuta ndi gasi, matanki agasi amadzimadzi, zipolopolo zamphamvu zanyukiliya,
ma boilers ng'oma za nthunzi, masilinda a gasi amadzimadzi, mapaipi amadzi othamanga kwambiri a malo opangira mphamvu yamadzi, ma volute a turbine ndi zida zina.
ndi zigawo.
