The promise of Primus Line® is big: A professional rehabilitation with the internationally proven technology extends the lifetime of a pipeline by at least 50 years. This promise is on the one hand based on the extensive personal understanding of quality of each individual employee as well as of the own department for quality assurance and on the other hand on many meticulously planned steps of quality control from goods receipt to delivery and beyond.
In addition to this, an independent, external testing laboratory supervises in semi-annual checks the compliance with the own company standard and the standards fixed in Technical Rule VP 643 which are the prerequisites for the DVGW type examination certificate.
