Welcome to Krah Group - The solution for large plastic pipe systems

Meeting your personal requirements – TAILORMADE SOLUTIONS

Since 1968 Krah has been developing and producing Krah helical extrusion pipe production technology in the Westerwald region of Germany.

The Krah production technology is a helical extrusion (spiral wound) process that allows to produce profiled pipes for gravity application, solid wall pressure pipes and all kinds of special wall structures to produce fittings, manholes and accessories. Due to the advanced technology and a continuous development process, Krah Pipes can be produced as a seamless, smooth and inspection-friendly inner surface together with an integrated socket spigot for electro fusion jointing and even for other types of jointing technologies. The production procedure provides the possibility of customized and cost-efficient pipe design, especially for the required application, by the help designed wall structure.

The pipe system can fulfill all requirements for a standard pipe and for tailor-made (engineered) pipe system.
