SA387 GR.21 CL1 Pressure chombo zitsulo mbale

ASTM A387 Gr 21 CL 1 ndi mbale yachitsulo ya chromium molybdenum alloy yomwe imapangidwira makamaka kuti ikhale yotenthetsera ndi zotengera zopanikizika zomwe zimapangidwa ndi kutentha kwakukulu. Zomwe zili mu Cr 3.00% ndi zomwe zili ndi Mo 1.00%. Kalasi iliyonse kupatula giredi 21L, Grade 22L, Grade 91 ndi 911 imapezeka m’makalasi awiri a milingo yamphamvu kwambiri.ASTM A387 GRADE 5 Class 1 - Alloy steelASTM A387 GRADE 5 Class 1 A high quality ASTM A387 GRADE 5 Kalasi 1 kapena chrome molyb aloyi zitsulo mbale cholinga makamaka ntchito weldable carbon zitsulo kuthamanga ziwiya pa kutentha okwera.

Miyezo Yotchulidwa pa ASME SA387 Alloy Steel Plate

ASME

• SA20/A20M: Zofunikira zonse za mbale zotengera zotengera.
• SA370: Mayeso oyeserera azinthu zamakina achitsulo
• SA435/A435M: Kuwunika molunjika kwa akupanga kwa mbale zachitsulo
• SA577/A577M: Kwa akupanga ngodya mtengo kufufuza mbale zitsulo
• SA578/A578M: ​​Pakuwunika kwamtengo wowongoka kwa UT kwa mbale zopindidwa zachitsulo mu ntchito zapadera
• SA1017/A1017M: Kufotokozera kwa mbale zokakamiza zazitsulo zachitsulo, chromium-molybdenum-tungsten

Chithunzi cha AWS

• A5.5/A5.5M: Low aloyi zitsulo maelekitirodi kwa chishango zitsulo arc kuwotcherera.
• A5.23/A5.23M: Maelekitirodi achitsulo otsika a alloy a fulxes owotcherera arc omira.
• A5.28/A5.28M: Kwa kuwotcherera kwa arc yotetezedwa ndi gasi
• A5.29/A5.29M: Kwa kuwotcherera kozungulira kozungulira.

Chithandizo cha Kutentha kwa SA387 Chrom Moly Alloy Steel Plate

Chitsulo cha Chrome moly alloy zitsulo pansi pa ASME SA387 chidzaphedwa chitsulo, ndi kutenthedwa ndi kutentha, kutentha, kutentha ndi kutentha. Kapena ngati wogula avomereza, kuziziritsa kofulumira kuchokera ku kutentha kozizira kwambiri ndi kuphulika kwa mpweya kapena kuzimitsa kwamadzimadzi, kutsatiridwa ndi kutentha, kutentha kochepa kudzakhala monga pansipa:
