Understanding Pipe Standard Specifications and Their Applications

For pipeline projects in wastewater collection systems, standard specifications are frequently cited in the project design and pipe manufacturing process, e.g. ASTM standard specifications. Different pipes have different standard specifications, and many pipes have more than one standard specification. In most cases standard specifications outline the minimum requirements in the pipeline industry, and they are often more than sufficient to meet the project application requirements. However, it is prudent to understand the specific requirements and the applicable conditions, especially for large pipeline projects with unique features. This paper will review the current pipeline standard specifications for four types of pipe that are commonly used in wastewater collection systems: Vitrified Clay Pipe (VCP), Reinforced Concrete Pipe (RCP), Polymer Concrete Pipe (PCP), and Fiberglass Reinforced Pipe (FRP). Differences among pipe standard specifications will be reviewed and their impact to pipe applications evaluated. Several heuristic models related to pipe applications will be discussed.
