Special Tube Expanders

Fin-tube Expander

This tool expands thin wall tubes of copper, brass or aluminum to fix the fins firmly, over the entire length of the tube.

With this operation the thermal transmission between fins and tubes will be optimized. This tool, normally is supplied without a mandrel extension, that is brazed accordingly the customer needs.

Manufactured to OD tubes from ¼” up to 1”.

Chilled Tube Expander

It reuses exhaust air from the pneumatic rolling motor to cool itself, thereby obtaining a longer tool life. It is usually applied in stainless steel tubes, or in high alloy steel tubes.

Step Expander

For thick tube sheets. Provides faster operation in very thick sheets, without removing expander from tube.

Refinery Expanders

Fabricated to suit special needs for rolling tubes in refinery fittings.

Sharp Bend Tube Expander


This tool has a mandrel travel reduced to a minimum due to its special taper.

The short mandrel is retained by means of a special fixture.

They are designed to suit special needs in compact boilers.

Reverse Expander

When expanding tubes inside very long sheets, the tubes elongation can yield a stress/ strain situation that will compromise the equipment structure.

The reverse expander eliminates this problem as it cold works the tube from the inner region to end face direction.

The expansion is started in the inner sheet face and the tool travels backward to tube end. The expansion is made in several steps.

Tube Expander with Nylon Guide

Suitable for thin walled tubes. The guide protects the tube against the contact with the cage, avoiding scratches.

Flange or Fitting

Used to produce a firm joint between a tube and a flange or fitting.

Tube Expander for Sugar Plant

Tube expander for vacuum evaporator of boiler for sugar plant

Lubricant Coolant Fluid

The LUBRICANT-COOLANT fluid is ideal for the tube rolling expansion, contributing to the process efficiency. It is used for all types of rolling expansions.

Its biodegradable formulation, totally free of oil, reduces the impact to the environment. It has an excellent performance, excellent cooling and high lubrication, comparable to integral oils.


  • Increases the useful life of the tube expanders
  • It does not contaminate the tubes and the plate
  • High protection against oxidation
  • Easy to clean remaining fluid
  • Biodegradable

Method of use: It is used diluted in water.
