A system of elements for the formation of pipelines in units for channeling and distributing a gaseous or liquid fluid that is under pressure or under vacuum. The pipelines are created starting from an extruded section pipe with a four-sided cross section having at least one central longitudinal hole and gripping elements along the corners of its walls. A joint which can be inserted tightly into the hole of consecutive section pipes makes possible their connection with the transmission of fluid. A fixing clamp is mounted on the adjacent ends of the consecutive pipes and engages with the gripping elements to mechanically lock the pipes among one another.
