PIPE CHART
Overview
The PIPE CHART is one of the most frequently accessed engineering tools for designers, fabricators, welders, QA inspectors, and maintenance teams. It provides quick access to verified stainless steel pipe dimensions, nominal size conversions, schedules, OD/ID values, and weights per foot. This chart reduces design time, prevents ordering errors, and ensures accurate fabrication in both industrial and hobbyist applications.

Technical Structure
The PIPE CHART provides a consolidated technical reference for all common stainless steel pipe sizes, schedules, mechanical properties, and dimensional tolerances required for engineering calculations and fabrication accuracy.
- Nominal Pipe Size (NPS): Standardized size system used for piping components.
- Outside Diameter (OD): Constant across schedules for each NPS.
- Inside Diameter (ID): Varies depending on wall thickness and schedule.
- Wall Thickness: Based on SCH 5S, 10S, 40S, 80S, XXH, and other industry schedules.
- Weight Per Foot: Critical for hangers, supports, rigging, and loading calculations.
- Material: Commonly 304/304L, 316/316L, Duplex 2205, and high-alloy variants.
- Tolerances: Based on ASTM A312, ASME B36.19, and A999 dimensional requirements.
Applications
- Pipe Sizing: Determine correct OD/ID and schedule for pressure, flow, and structural needs.
- Fabrication & Welding: Ensures accurate preparation for fit-up, beveling, and root gaps.
- OEM Engineering: Used for spec sheets, drawings, and equipment design validation.
- Field Installation: Verifies compatibility with existing systems during retrofits.
- Hobbyist/DIY: Perfect for small-scale stainless projects requiring exact dimensions.
Industries Served
- Food & Beverage: Sanitary piping layouts and process flow modeling.
- Pharmaceutical & Biotech: Skid layouts, utility systems, and validated piping designs.
- Water Treatment: RO/DI systems, pressure manifolds, and pump discharge lines.
- Chemical Processing: Corrosion-resistant pipe sizing and system upgrades.

Integration & Workflow
The PIPE CHART integrates into the workflow of engineers, inspectors, fabricators, and purchasing teams by standardizing dimensional data and reducing design-cycle errors.
- Design Integration: Used for CAD models, P&IDs, isometrics, and spool drawings.
- Procurement Accuracy: Ensures exact size, schedule, and quantity selection.
- Fabrication Efficiency: Eliminates measurement mistakes during cutting and prep.
- QA/QC Verification: Confirms pipe meets dimensional and schedule tolerances.
- Project Documentation: Adds consistency to submittals, reports, and datasheets.
