Double-walled piping

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


The piping and fittings are made of acid and corrosion-resistant plastics as e.g. PE 100, PP-H (GF make) or PVDF. We can also supply them in different materials 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. All double-walled components are simultaneously welded.

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; 45° bends, 90° bends, T pieces, pipe branches, fixing points, sensor points, reducers and transition components.

The leakproofness of the double-walled piping can be monitored with several systems:
  • Visual monitoring
  • Liquid sensors
  • Pressure monitoring

      Insite      Outsite
    25 x 2,3      50 x 2,9
