PPI releases new technical document on pipe sizing for seismic-prone areas
The Municipal Advisory Board (MAB) of the Plastics Pipe Institute, Inc. (PPI) announced the publication of a new technical document that provides data for high-density polyethylene (HDPE) water lines in earthquake-sensitive areas. MAB-9, Design of HDPE Water Mains for the Lateral Spread Seismic Hazard is available for free on the group’s website.
“This is the first document of its kind that provides the rationale, data and formulas for determining the proper wall thickness for a fused, highly ductile, flexible HDPE water main in a seismically sensitive area, subjected to an induced lateral spread,” stated Camille George Rubeiz, P.E., F. ASCE, co-chair, Municipal Advisory Board and senior director of engineering, Municipal and Industrial Division of PPI.
