simplesta® SH stainless steel pipe system

New standards
with the MPA NRW

simplesta® SH – the new standard for stainless steel


The MPA NRW has been testing our simplesta® SH stainless steel pipe system since spring 2018 – the system's resistance has been confirmed in a series of trials. Structural performance, functionality and reliability has been proven even over very long cycles and under extreme loads. The simplesta® SH stainless steel pipe system system works!

Initial testing was completed in August 2019 and nothing else stood in the way of official certification. We are the first manufacturer to be able to give our customers a performance guarantee based on reliable data from the Materials Testing Office for longitudinally welded pipes and press fittings made of stainless steels for use in heating installations and cooling circuits.

In addition to the initial testing and alongside our – in our view obligatory – internal quality management, the MPA NRW also carries out regular inspections.

Testing carried out: April 2018 to August 2019
Certification number: MPA NRW - 00648
