Pipe Profile Series: Ductile-Iron Pipe DVD
Water operators learn all about ductile-iron (DIP) pipe in this training DVD, part of the five-DVD Pipe Profile Series.
Before DIP, cast-iron pipe was used in Europe for centuries and later in the US and Canada. Ductile-iron, introduced in the 1950’s is recognized as one of the most significant developments in the pressure pipe industry. DIP has all of the good qualities of gray cast iron pipe plus additional strength and “ductility”, which is the ability to deform without cracking. Ductile-iron piping systems have great versatility when combined with the diversity of fittings, valves, hydrants, encasements, linings, gaskets and specials with more than 15,000 variations of fitting patterns currently available.
The DVD illustrates the characteristics of ductile-iron pipe used in water supply. Areas of discussion include:
• Advantages, disadvantages, and concerns
• Thermal effects and weathering
• Guideline for proper transportation, receiving, unloading, inspection, and storage
• Working characteristics
• Basic installation procedures and considerations
• Bedding and backfill requirements
• Basic pipe repair
• Maintenance, testing, and record-keeping
All information in Ductile-Iron Pipe is based on related AWWA Standards and AWWA Manuals of Water Supply Practices--your assurance of current, water industry-approved information.
