Proper selection of pipeline materials for any utility system or portions thereof should be based on a wide variety of factors, not just price alone. Based on actual material properties and their related values, along with experiences through the years, this audience-driven comparative-style presentation considers topics and assessments such as: 

  • Internal pressure design and pressure ratings – there is a notable difference, 
  • external loading and the trench contributions required for various pipeline materials, 
  • the three-prong flexible conduit theory of design and why it matters, 
  • quality assurance and proof-testing employed during product manufacture, 
  • handling, storage, and protection nuances related to each pipeline material, 
  • installation and hydraulic differentials among popular pipeline materials, and 
  • the universal constant of fittings.
