Measurement of the width of the shipping container in the picture with a ruler: ~12.8 cm or ~128 mm.
Measurement of the pipe in the picture with a ruler: ~5mm
So the pipe diameter / container width ratio is ~0.039.
Standard shipping container width: 2.438 meters or 2438 mm.
So the naked pipe appears to have a diameter of: 95 mm.
That ain't no DN40 pipe. Even if we are conservative and say the pipe in the picture is only ~3mm, it would still appear to have an outer diameter of 57 mm, which would be pretty close to DN50 piping.
