We offer a specified test scheme for pre-qualification of pipe conduits for pipe-in-pipe systems. When installing water distribution in domestic houses and apartments, the PEX supply pipe will be covered by a corrugated pipe, often called a Pipe in Pipe system. The inner pipe is a PEX plastic pipe with very stringent regulations. The outer corrugated sleeve has a security function of leading away potential leaking water, if the PEX pipe gets a rupture. These tubes had no regulations until recently, and due to quality variations and problems of the tubes it has resulted in cracking tubes and several insurance claims. Testing methods A new test scheme, Sintef Byggforsk “Test method for pipe in pipe systems, for approval", has been implemented in Norway and includes the analysis of several quality parameters: Pigment dispersion and homogeneity Raw material quality vs. gels Thickness distribution of the profile Presence of notches in the tube profile Stress-crack resistance UV testing Norner offers pre-qualification according to the above mentioned tests of the pipe-in-pipe systems. Qualified systems have to be sent to Sintef Byggforsk to obtain a Sintef technical approval.
