CALCULATOR : ASME B31.1 Plastic Pipe Diameter And Wall Thickness Schedule [FREE]   ±

Calculate ASME B31.1 plastic pipe diameter, minimum wall thickness and pressure design thickness from pipe schedule wall thickness or dimension ratio (SDR or SIDR) (ASME B31.1 section 104.1).

Select the pipe schedule (NPS or ISO), pipe diameter and wall thickness or dimension ratio, or use the user defined options. Use the Result Table option to display the pipe schedule with nominal wall thickness, minimum wall thickness and pressure design wall thickness for the selected diameter. The dimension ratio is calculated from the pressure design thickness (nominal thickness minus mechcanical allowance and fabrication allowance).
