Ductile Iron Pipe FAQs
Q: What makes ductile iron pipe better than PVC for water mains?
A: Ductile iron pipe offers several advantages over PVC including higher pressure ratings, greater impact resistance, better load-bearing capacity, and superior fire resistance. While PVC may be initially cheaper, ductile iron pipe typically provides longer service life and lower lifetime costs due to its durability and minimal maintenance requirements.
Q: How does ductile iron pipe handle corrosive soils?
A: Modern ductile iron pipe is protected against corrosion through high-quality external coatings (typically polyethylene) combined with cement mortar lining. For extremely aggressive environments, we offer additional protection options including V-Bio enhanced polywrap and sacrificial anodes. These systems have been proven effective in even the most challenging soil conditions.
Q: What are the installation advantages of ductile iron pipe?
A: Ductile iron pipe offers multiple jointing options (push-on, mechanical, flanged) that allow for fast, reliable installations. Its weight-to-strength ratio means it can be installed with commonly available equipment, and its flexibility (up to 5 degrees deflection per joint) allows for easier installation around obstacles compared to rigid pipes.
