What Are Some Common Misconceptions Associated with Ductile Iron Pipe?
12/04/2020 In Products TechnicalIn 1492, Christopher Columbus was shocked when his ship made landfall in a land Europeans had never explored. Along the way, he proved that Earth isn’t flat after all. Right?
Wrong: Despite a persistent legend, neither Columbus nor his Spanish patrons thought Earth was a finite plane instead of a round planet. That was thanks to scientists, philosophers, and mathematicians who, as early as around 600 B.C., made observations that Earth was round. Using calculations based on the sun's rise and fall, shadows, and other physical properties of the planet, Greek scholars like Pythagoras and Aristotle determined that the planet is actually a sphere.1
So, what’s the point of today’s history lesson? It often reminds me that there are numerous myths associated with Ductile iron pipe (DI pipe), and in this Iron Strong Blog, we’ll list some of those ideas, provide factual data, and discuss why they are simply misconceptions.
