Confirm the equipment identity
Provide a readable nameplate and any existing part codes. Appearance or approximate dimensions alone do not prove equivalence.
Include process conditions
Describe fluids, temperatures and cleaning conditions, including changes since installation. Confirm whether the previous material remains appropriate.
Define the service scope
Separate parts supply from inspection or refurbishment. Assembly and tightening require the model manual and the appropriate service procedure.
Prepare for the discussion
- Fluids, composition and relevant material requirements
- Flow rates and inlet/outlet temperatures on both circuits
- Design conditions and allowable pressure drop on each side
- Exact model, nameplate and current technical documents
