Slot tubes are welded structures with the support profiles being rods in the axial direction of the tube and surface profiles spirally wound around the support profiles.

Standard constructions of slot tubes (special constructions are possible on request)

The designation of a slot tube describes its construction as follows:
surface wire / support wire x number of support wires.
Example: 12S/Q25 x 8
This means that the profile wire is 12S. The support wire is Q25 and there are 8 support wires, equally spaced over 360°.

Slot tubes with dimensions and/or tolerances other than those described below, are available on request.
