Double compressed extensible aluminum pipes

Double compressed extensible aluminum pipes

The double compressed extensible aluminum pipes are used for air conditioning equipments, emission and dust evacuation, for light suspensions (ventilation) and industrial or household cooking hoods.

On the romanian market, Pro Invest is the first manufacturer of compressed extensible aluminum pipes with a compression rate of 18% (out of the total length of 3m). This type of pipes is used 100% in the Western Europe because of its obvious advantages.


  • Inner diameter (mm):  50/63/75/80/90/100/110/115/120/125/130/140/150/160/180/200/250/300
  • Length (m): 1.5/2.5/other dimensions on request


  • Volume reduced through the 18% compression rate (out of the total length of 3m) leads to:
    • storage space savings
    • transport space savings, both for the trader (optimizing logistic costs) and for the final customer
    • a better shelf exposure compared to the corrugated extensible aluminum pipe, that comes off the shelf
    • imporoved shipping to the final customer, compared to the corrugated extensible aluminum pipe
    • increased stiffness reduces the risk of deformation and crushing during manipulation
  • Durable and resistant in time
  • Very elastic (can be compressed or extended easily)
  • High resistance to breakage
  • Resistant to temperature up to 270°C
  • Short assembly time
  • Increased safety due to the european standards
