Tri-clamp finned cooler: clamp-on halves for a 2 in tube — dimension sheet
Source: Xem Studio, https://xemstudio.com/objects/tri-clamp-finned-cooler/  (CC BY 4.0)
Basis: ASME BPE 2 in tube OD (Ø50.8); clearance under a standard clamp; fin sizes are design values
Catalog version: 2026-10-20

Sizes: see table below
- Two halves close on the tube OD between the clamps of a 3 in spool (61.9 mm of plain tube); each half is 56 long with a 3 mm sleeve and nine Ø88 × 2 fins at 6 mm pitch.
- The halves leave 1 mm between them; four M4 × 30 screws and nuts through the ears pull them onto the tube (clamp fit).
- The fins clear the clamps: the clamp ring reaches 7.1 mm past the ferrule face, the cooler starts 3 mm beyond that.
