CASING PIPE ROTH 25x20mm 60m WHITE PE-HD

NORDTEST NT VVS 129 is a common Nordic test method designed for pipe-in-pipe systems. It means that pipes, installation pipes, wall enclosures, wall penetrations, distribution cabinets, etc., are tested as a complete system where all components function together to form a fully integrated pipe-in-pipe system. The cabinet and all penetrations must be watertight so that any potential leak is directed back to the cabinet's drain pipe or to a space with a sewer connection. The pipe-in-pipe system must also be replaceable according to the Nordtest method. By installing the Roth pipe-in-pipe system, you easily reduce the risk of water damage.
