Rows
- Horizontal rows of tubes in the fin pack | CL - Casing Length
CL = EP1 + FL + EP2
|
| FPI - Fins Per Inch | CD = Casing Depth
- CD must be greater than (# Rows) * (Centerline Distance Between Rows)
|
| FH - Fin Height | Max
- Dimension from the edge of the fin pack to the outside of the return bend |
| FL - Fin Length
| L - Connection Length |
SP1, SP2 - Sideplate Flanges
- Called sideplates because coil face lays flat on the table during tube expansion | "C" Dimension
- Dimension from the edge of the fin pack to the outside of the header
|
EP1, EP2 - Endplate Flanges
- Also called tube sheets | OAL - Overall length
- Dimension from the edge of the return bends to the outside of the header
OAL = MAX + FL + C
|
CH - Casing Height
CH = SP1 + FH + SP2 | S, R, E, F - Connection Locations
- Measured from the sides of the casing to the centerline of the connection |
