Heat Transfer & Process Equipment replacement guide
Identify heat exchangers, coils, steam traps, condensate equipment, strainers, mixers, agitator components, process skids, and related service parts by thermal duty, media, materials, and connection geometry.
Evidence boundary. Process-equipment replacement is application-specific. Keep thermal duty, pressure drop, materials, connection geometry, and code requirements ahead of nominal size matching.
