STEP-FLEX 2 ø 219.1 - 812.8 mm
STRAUB-STEP-FLEX is used if the pipes have different external diameters.
The possible diameter differences of the pipes to be connected can be 10 mm up to max. 30 mm.
Under pressure, STRAUB-STEP-FLEX pipe couplings, due to the diameter differences, are always pushed by internal forces in the direction of the smaller pipe diameter and must therefore be secured against slipping using appropriate measures.
STRAUB pipe couplings are made of the same or different materials depending on the diameter and size. The following overview shows the details. If you have any questions, please contact our application technology department.
