Plastic Pipe

Plastic Pipe Center - PPC

The place to go for all questions concerning plastic pipes.

The Plastic Pipe Center combines our expertise in the field of plastic piping systems across the various divisions of SKZ:

In our testing laboratories (acc. to DIN EN ISO/IEC 17025), all common tests on components for pipelines are carried out – from bursting pressure tests on micro ducts for broadband expansion to determination of ring stiffness on DN 1000 wastewater pipe. 

Our inspectors visit the production sites of our customers worldwide and carry out product monitoring (acc. to DIN EN ISO/IEC 17020) for many certifiers. 

Our certification body (acc. to DIN EN ISO/IEC 17065) certifies more than 150 customers according to more than 100 different standards and guidelines concerning the piping sector (e.g. according to our SKZ HR specifications for tests and inspection).

Piping systems

Drinking water and gas supply

What do drinking water and gas piping systems have in common? In both applications, the individual components (pipes, fittings, valves, ...) of pressurized piping systems are subject to the strict-quality requirements, which are regulated by the following product standards: 

  • DIN EN 12201-1/-2/-3/-4/-5/-7
  • ISO 4427-1/-2/-3/-5
  • DIN EN 1555-1/-2/-3/-4/-5/-7
