Plastic Piping Systems in the Chemical Industry

  • Polyethylene (PE)
  • Polypropylene (PP)
  • Unplasticised polyvinyl chloride (PVC-U)
  • Post-chlorinated PVC (PVC-C)
  • Polyvinylidene fluoride (PVDF)
  • Ethylene chlorotrifluoroethylene (ECTFE)

  • Perfluoroalkoxy alkanes (PFA)
  • Modified polytetrafluoroethylene (PTFE-M).

The name of our dual-laminate system is KERAVERIN®. These pipes comply with the applicable DIN standard 16965 part 2/ pipe type B.

Glass fibre reinforced plastic (GRP) without thermoplastic linings

Our pipes without thermoplastic lining are covered under part 4/ pipe type D as GRP pipes with a chemical-resistant layer (KERAPOLIN®), or under part 5/ tube type E as highly chemically resistant pipes with a high resin content (ALPHACOR®).

The operating temperature range is between -50 °C and approximately 200 °C, depending on the composite material used.

Our standard portfolio comprises products with nominal diameters from DN 25 to DN 1000, with grading of the standard nominal pressure varying, depending on the nominal diameter, and starting at PN 16. We're well equipped for handling large nominal diameters too. We can fabricate items up to 5.5 m in diameter.

Naturally, we can also supply electrically conductive material systems suitable for use in areas subject to explosion hazards. Our pipes can be fabricated to be compliant with pressure equipment directives. We are also certified according to module H/H1.

Our components are used wherever highly corrosive media must be handled, such as for transport in processing and storage facilities. Whilst conventional materials fail here, due to insufficient resistance, STEULER-KCH pipes are up to the job.

STEULER-KCH's experienced specialists are there to provide you with expert assistance, from the initial consultation through to final assembly – in Germany and around the world.

Our particular strength lies in consultancy: we work together with our customers to select the combination of materials (liner, fibre reinforcement, resin matrix, etc.) best suited for the chemical, mechanical and thermal stresses to which the pipe will be subjected. We develop custom combinations of materials in close consultation with our customers from the chemical industry.
