The Ductile Iron Pipe Systems manual provides planners, construction companies and network operators, as well as higher education and training institutions, with an overview of current expertise in the field of ductile cast iron pipes, valves and fittings. The individual chapters are regularly checked to make sure they are up to date and revised by the EADIPS technical committee if necessary. In addition, the manual is supplemented by new, user-oriented chapters.
Calculating wall thicknesses for ductile iron pipes
Because of changes in European regulations, Chapter 5 “Pipe design and wall thickness calculation” (edition 04-2008) has been revised and replaced by the new Chapter 5 “Wall thickness calculation for ductile iron pipes“ (edition 08-2018).
The Chapter 5 now covers the following points:
Explanation and illustration of the stresses in the pipe wall of push-in-joints and restrained socket joints
Development of minimum pipe wall thicknesses
The effect of longitudinal bending strength and ring stiffness on the calculation of pipe wall thickness dimensions
Comparison of wall thickness classes (K-classes) and pressure classes (C-classes) for non-restrained flexible pipes
The effect of restrained socket joints on the wall thickness of ductile iron pipes
