A resource that visually represents standard measurements for pipes, typically in Portable Document Format, provides essential information for selecting the correct pipe dimensions for various applications. It often includes nominal pipe size (NPS), outer diameter (OD), wall thickness, and inner diameter (ID) for different schedules or pressure classes. For example, a chart might indicate that a 1-inch Schedule 40 pipe has an OD of 1.315 inches and an ID of 1.049 inches.
Such a visual aid is crucial in engineering, plumbing, and construction as it ensures accurate specification and procurement of piping materials. Its use prevents mismatches in connections, flow restrictions, and potential system failures. Historically, standardized pipe sizes were developed to promote interoperability and ease of manufacturing across the industry.
