Structured Wall Pipes

A structured wall pipe or profiled pipe has a very low weight, but at the same time can be used for high external load applications. The supportable static load is determined for every profile geometry by the factors; elastic modulus [N/mm²] of the respective material and the moment of inertia of the profile geometry [mm4/mm] referring to the pipe diameter. The result is called ring stiffness. By using a profile design pipe, the weight can be reduced up to 65% compared to a solid wall pipe with the same ring stiffness. Krah pipes offer the best security and durability. The wall thicknesses of our pipes can be adapted in various sizes to cater the respective load. The main properties of the structured wall pipes is the smooth inside and the profiled outside. The fields of application for these kinds of profiles are pipeline systems like sewer, drain, storm drain and ventilation
