HOSES

Palle Knudsen Kunststoffabrik ApS offer hoses in a wide variety of materials and dimensions.

The objective is to find a product which meets the customer's requirements concerning functionality, properties and price.

Before finally choosing the material it is vital to have a thorough knowledge of the surroundings and conditions in which the hose will be functioning.

The wrong choice can cause difficulties during installation, lack of functionality and in worst case collapse of the hose.

 

It is important to know about the following conditions:

  • Temperatures (minimum and maximum)
  • Service pressure
  • Chemical environment
  • Work environment (impact blows, wear, flexibility, sunlight, etc)

Other requirements like colour, food approvals, burnability etc. might also influence the choice.

If your search for information fails, please use the link to the material description or feel free to contact us for any advice and guidance in connection with choice of material.
