SKO – double-walled piping according to DVS 2210 part 2


The piping and fittings (make + GF+) consist of acid-resistant and corrosion-resistant plastics as e.g. PE, PP or PVDF. Other materials available upon request. All individual components of SKO- double-walled piping are manufactured according to DIN. The production of the two-pipe components is made in accordance with the valid DVS directives. The welding of all double-walled components is made by simultaneous welding.



The product portfolio also comprises straight pipes in standard lengths of 6 m for PE, or 5 m for PP and PVDF as well as all fittings; bends 45 °, bends 90°, tee pieces, pipe branches, fixing points, sensor points, reducers, transition components,…



The tightness of the double-walled piping can be monitored with several systems:

• Optical monitoring
• Liquid sensors
• Pressure monitoring
