Pre-insulated curved HDPE-jacket pipes (diffusion barrier)

Pre-insulated curved HDPE-jacket pipes (diffusion barrier)

In the range of diameters DN20 – DN80, pipes are bent mechanically on the construction site.
When ordering, please specify the diameter, wall thickness, bend radius, bend angle and length of the section.
Other pipe thicknesses are available on request.
Production to individual order, non-returnable.
