Finned Tube Supply — Low Fin Tube

Low Fin Tube

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.

Overview

One continuous material, no bond to fail

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.

  • Fins rolled directly from the base tube material — no separate fin component
  • No bond line to fail — fin and tube are one continuous material
  • Available in straight & U-bend configurations
  • Fin density up to 26 FPI (1023 FPM)

How It Works

How low fin tube is made

A cold-rolling process that forms the fin from the tube itself.

1

Base Tube Selection & Prep

Base tube material and dimensions are selected and prepared for rolling.

2

Cold Rolling Setup

The tube is loaded onto a dedicated fin-rolling machine.

3

Progressive Cold Rolling

Fin geometry is formed from the tube wall material in successive rolling passes.

4

Straight or U-Bend Forming

Finished tube is left straight or formed into U-bend configuration as required.

5

Dimensional & Pressure Testing

Fin geometry, wall thickness, and pressure integrity are verified against specification.

Manufacturing Equipment
