Expansion chamber

Hydraulic expansion unit and expansion probes designed for expanding tubes in tube sheets. It ensure a uniform expansion within a single operation and over the complete length. Applications : critical industries such as nuclear and thermal power plants, automotive, military and naval aplications Applies to all types of materials based ont the thickness and admissible pressure. Versions: hydraulic or electric. Pressures: 1000 – 5000 bar Tube diameter: 10 to 80 mm. Plate thickness: 25mm to 800mm. For any further information and feasability review, please do contact us. The hydraulic expansion consists in making a tube/plate seal to allow the tubes to be pressurized. The hydarulic expansion process is as follows: Inserting the probe into the tube Activation of the trigger Water is injected into the probe The pistons are pressed against the seals (tube/string contact) Pressurization and pressure increase Pressure decrease and purging of the system Withdrawal and beginning of a new cycle
