Minimum bend radius of 25mm MDPE water pipe.

I need to route some MDPE water pipe around the outside of my footing trenches to the static caravan. Given the cold weather can someone suggest a reasonable bend radius at a 90 degree corner?

 

The current air gap between footing blockwork and mud trench wall is 120mm.

15x the diameter increasing to 25x in very cold weather.

That is consistent with the radius of the delivered coil, thanks for the guidance.

 

As delivered the 50m coil diameter was 900mm = 450 bend radius = 18x pipe diameter.

 

In the end I used a 2m section to test the tightest bends through the foundation trenches, it was simpler to route the pipe than the maths indicates.
