Awwa c900 dr18 pipe has a pc of 235 psi for the 4 inch size through the 60 inch size.
Pvc sdr pipe pressure ratings.
The pipe series s can be calculated as.

The relationship between the sdr and the pressure rating is given by lames formula for the hoop stress in thick wall cylinders.
They are highly resilient with high tensile and high impact strength.
It is commonly recommended to limit these.
These ratings are based on a constant pressure.
Pipe series s.
The maximum pressure rating for sdr pipe remains the same at different diameters.
S pipe series.
Appropriate temperature de rating factors must be applied to determine the maximum allowable pressure when working at elevated temperatures greater than 73f.
The maximum service temperature for pvc is 140f.

Pvc pr 160 pr 200 and pr 315 are for pressure systems where temperatures will not exceed 140 f.

As a consequence a high sdr pipe has a low pressure rating and low sdr pipe has a high pressure rating.
Adjustments may be required for pressure variations.
The pressure ratings shown are for water non shock 73f with plain end pipe.
Pipe series s is a dimensionless number related to the nominal outside diameter and wall thickness of a pipe.
Where dn is the nominal outside diameter of the pipe and en is the nominal minimum wall thickness of the pipe.
Therefore a higher sdr indicates a thinner walled pipe at any given diameter.
