Soft annealed ala carbon alloy 625 na-ọtụtụ ebe na-eji kemịkalụ usoro ụlọ ọrụ, ebe ya mma corrosion eguzogide na elu ike na-enyere ya na-eji dị ka mkpa structural akụrụngwa. Enwere ike iji alloy 625 mee ihe na ngwa ebe ọ na-abanye na mmiri mmiri ma na-enwe nrụgide dị elu.
Mpaghara ngwa a na-ahụkarị: 1.
1. Akụrụngwa maka usoro kemịkalụ organic nwere chlorides, ọkachasị ebe a na-eji ihe na-akpata acidic chloride.
2. Digesters na tankị ịcha ọcha maka ụlọ ọrụ pulp na akwụkwọ.
3. Ụlọ elu absorption, reheaters, flue gas inlet baffles, Fans (wet), agitators, deflectors na flues na flue gas desulphurization usoro.
4. Ngwa na akụrụngwa maka imepụta ngwa na gburugburu acid gas.
5. Acetic acid na ethyl mmanya mmeghachi omume generator. 6. Sulfuric acid condensers.
