Ductile Iron Pipe Guidelines

Ductile Iron pipe manufacturers have been successfully welding Ductile Iron pipe for many years and should be consulted on their recommendations for field welding and torch cutting their product. This manual is intended as a guide for field welding and cutting cement-mortar-lined and unlined Ductile Iron pipe.

These guidelines are the result of testing conducted by DIPRA, Federal Signal Corporation, Induron Coatings Inc., and the Missouri University of Science and Technology to establish effective and safe procedures for pressure washing cement-mortar and Protecto 401 lined Ductile Iron Pipelines.

This handbook is full of useful information for designers and installers of Ductile Iron Pipe. It covers many aspects of pipeline installation such as receiving and handling, trenching, installing, backfilling, testing and disinfecting, and service taps. It also contains a variety of useful miscellaneous information such as a listing of Ductile Iron Pipe standards, common conversion factors and dimensions, and weights of push-on and mechanical joint pipe. A convenient pocket-size version of this Guide is available.
