Production process

The wall of the pipe consists of a profiled outer layer and a flat inner layer, which are welded between the ribs and form a homogeneous wall. The outer profiled layer greatly improves the mechanical properties of the pipe, and significantly increases the stiffness of the pipe in the radial direction. The flat and smooth inner wall, in addition to additional security, allows easy installation of cables.

An auxiliary wire can also be inserted in the STIGMAFLEX® TK-K and STIGMAFLEX® EL-K pipes in coils on request. The wire is intended only for the introduction of a supporting rope, which later allows the retraction of telecommunication cables.
