ASTM A387 GR.91 CL.2 Plate is a chromium molybdenum alloy steel plate
intended primarily for welded boiler and pressure vessels designed for elevated
temperature service, which includes parts like heater tubes, heat exchangers,
and pipes in chemical fertilizer equipment as well as other industries related
to oil & gas production, power plant operations, etc. ASTM
A387 GR.91 CL.2 Plates have a higher concentration of Chromium than other
grades, which gives it excellent corrosion resistance and oxidation resistance
properties when compared with different grades of steel such as ASTM A516 Grade
70 or ASTM A285 Grade C.
中鋼開發電廠用高溫壓力容器用鋼 打破進口壟斷 自由 20240508
為促進國內能源轉型發展,中鋼(2002)開發先進高強度鋼材,近期成功開發出高溫壓力容器用鋼A387產品,擁有優異的耐高溫強度外,也具備延緩材料強度弱化的抗潛變特性,可使焚化爐或燃氣電廠鍋爐長期運轉下避免管槽受破壞,並降低維修成本,目前在國內已有成功銷售實績,打破進口壟斷現況,中鋼朝擴大國產化市占率目標邁進。
電廠發電設施通常需長時間於200倍大氣壓力的蒸汽壓及攝氏約450至600度的溫度環境下運轉,一般非耐高溫鋼材承受攝氏450度上的高溫時即迅速軟化,使得設備殼體材料斷裂塌陷而導致工安風險,因此發電設施的鍋爐、扇葉、連接管線或是焚化爐體等製作材料,必須擁有良好的抗氧化性、高溫強度、抗潛變能力與銲接性等性能。
