See Tube Rolling and Pipe Rolling Diagram. Centerline Radius (CLR) - Distance in inches from the center of curvature to the centerline axis of the tube rolling or pipe rolling bends. Abbreviated as CLR. See Tube Rolling and Pipe Rolling Diagram. Cold Tube Bending - The bending of pipe or shapes by cold working methods. Degree - Angle in degrees to which the pipe rolling bends are formed (i.e. 45 degrees, 90 degrees, 180 degrees, etc.) See Pipe Rolling Diagram. Easy Way (EZ) - Bending of a rectangular tube with its short side in the plane of the tube rolling or pipe rolling bend.
