How much does Blu-Lock Pipe bend

Minimum Bend Radius #

Tightening the curvature of a pipeline results in a smaller (tighter) bend radius. The minimum bend radius is defined as the smallest radius to which the pipe may be safely curved. To find the minimum bend radius (R) use the following ratio (a) and multiple it by the Outside Diameter (OD).

R=a(OD)

3/4″ Pipe #

The minimum bend radius for the 3/4″ Blu-Lock piping to prevent kinking is 20-1/4″.

If you are using a plow the 3/4″ Blu-Lock pipe can be bent to a tighter radius of 12-3/4″, but only for a short amount of time.

1″ Pipe #

The minimum bend radius for the 1″ Blu-Lock piping is 25″.

If you are using a plow the 1″ Blu-Lock pipe can be bent to a tighter radius of 13″, but only for a short amount of time.
