    Profiled wall HDPE pipes | Krah México S.A de C.V.

    Profiled wall pipe, gives as much rigidity to the pipe as it solid wall equivalent, at a fraction of the weight, resulting in lighter and less expensive pipes. Since every single appliion varies from one another, we design the profile wall in different geometries and sizes, to adapt the pipe to the conditions that are encountered in every single project.
