Fins cold-rolled directly from the base tube wall itself — no separate fin material, no bond line, for the highest mechanical and corrosion resistance in shell-and-tube service.
Low fin tube is manufactured using cold rolling of the fin directly from the base tube itself, on a dedicated fin-rolling machine. Rather than attaching a separate fin component, the fin material is formed from progressive cold-rolling passes of the tube wall material — meaning there is no bond line between fin and tube to fail in service.
Because fin and tube are one continuous material, low fin tube offers excellent mechanical resistance and corrosion protection, and is produced in both straight and U-bend configurations to suit shell-and-tube heat exchanger and oil cooler geometries.
