SDR or MOP Calculator

External pipe diameter Internal diameter
mm
Minimum Required Strength (MRS) Wall Thickness
mm
Factor of Safety (C)
Standard Dimension Ratio (SDR) Maximum Operating Pressure (MOP)
Bar
Standard Dimension Ratio (SDR) Maximum Operating Pressure (MOP)

How to use the calculator:

Select the External pipe diameter, MRS, C and either the SDR OR a value for the MOP.
If you select the SDR, the MOP is calculated or if you enter a MOP value, the SDR is calculated. When the SDR is calculated the MOP may be recalculated for the this SDR.
Values for the internal pipe diameter and the wall thickness are calculated automatically.
