Because ﬁttings and ﬂange connections are rigid compared to the pipe, the minimum bend radius is 100 times the pipe’s outside diameter (OD), when a ﬁtting or ﬂange connection is present in the bend. The bend radius should be limited to 100 x OD for a distance of about 5 times the pipe diameter on either side of the ﬁtting loion.

Is HDPE pipe tends to bend vertically, allowing radius at the center? Helium recovery at the National High Magnetic Field Laboratory Otherwise, the HDPE pipes have reasonable bending radii (32” for the 3” pipes and 27” for the 2”), allowing them to turn corners without requiring additional joints.
For example a 12" HDPE pipe may be safely bent to a radius of only 28 ft, which allows this pipe to be placed in a typical cul-de-sac without fittings. In addition, HDPE pipe will almost always have a tighter bend radius than the drill stem being used for installation.
2004/08/18· MINIMUM Bend radius for common drs are as follows: DR9 or thicker = 20 times od DR 9 to DR13.5 = 25 times od DR 13.5 to DR 21 = 27 times od greater than DR 21 = 100 times od ie. 8 in. IPS DR 11 HDPE pipe can be bent
Bending radius allowed by the manufacturer can vary. Verify the multiplier with the manufacturer. In no case shall the radius be less than 125% of the manufacturer’s permitted multiplier. HDPE pipe Dimension Ratio (DR) (percent) Puhui Pipe manufacturer in China

/12/11· 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 indies.
During installation, the minimum allowable bending radius, as shown below, should be observed. For curves of smaller radius, post formed bends or moulded fittings shall be used. The allowable radius of curvature depends on the temperature of the pipe and the SDR. The following table gives recommended minimum bending radii for pipes at 20°C.
