The consequences of large diameter pipe failure can be enormous due to the supply challenges failures may cause, as well as risks to public safety and the environment.
This conference was developed to address some critical issues related to large diameter pipe, especially options for rehabilitating large diameter pipe of various materials.
The conference covered pipe materials including steel, cast and ductile iron, and PCCP pipe. There have been some innovations in the past several years regarding the application of structural linings for large diameter pipe.
The conference included presentations from consultants, manufacturers, and utilities.
