Spirals

Palle Knudsen Kunststoffabrik ApS specialises in production of spiral hoses in a number of different materials which meet requirements for flexibility and functionality. 

Standard dimensions depend on material, but extend from Ø 4 to 16 mm with a working length from 2 to 8 m for PUR-spirals and 15 m for PA-spirals.

 

We can supply the spirals in various levels of hardness from Shore D 48 to Shore D 72.

PUR  is an extremely well suited material for flexible spirals due to its very fine elastic memory which ensures that the spiral keeps its shape and fine spring effect.

Typical applications are: Pneumatics, motor industry, hydraulic systems, industrial purposes and food contact.

MULTI-SPIRAL: We can offer a multi-spiral as an alternative to duo-spirals, which is a spiral-duo-hose (two PUR hoses glued or thermically tied to each other).

The multi-spiral combines materials, colours, dimensions and lengths by wrapping the individual spirals around each other. This makes it possible to choose the spirals according to specific requirements for e.g.: flexibility, service pressure or temperature.

The spirals are winded in opposite ways to avoid tangling. 

Besides larger freedom in the choice of materials and dimensions, the multi-spiral can ensure that the hoses do not counteract, as no stress has been built-up between the hoses, which is the case in duo-spirals.

Furthermore, the multi-spiral maintain form and functionality. In duo-spirals there is a risk that the adhesion between the hoses wears out in time.
