KRAH Profile tubes

Haplast is the only manufacturer of KRAH profile pipes in Norway.

We use KRAHTMtechnology, which makes it possible to produce solid PE profile pipes up to 3 meters in diameter. The pipes can be produced in several ring stiffness classes - including SN-8.

Profile types for KRAH- pipe

Haplast produces KRAH™ profile pipes in several profile types. This allows us to adapt the pipe wall to the application, dimension, load and desired ring stiffness.

The difference between the profile types lies in how the pipe wall is built up. Some profiles provide low specific weight and high ring stiffness, while others provide extra robust walls, smooth surfaces or better properties for further processing into sumps, tanks and special products.

We help you choose the right profile type based on the needs of your project.

VW

VW is a smooth-walled profile type with a compact tube wall. It is well suited where a smooth surface, high material thickness and a robust construction are desired.

Typical applications:

  • Basins
  • Mind
  • Special products
  • Products requiring welding, machining or internal cleaning
