Specify Radius Height Degree of Arc(Height) Length of Material Needed
Quick Reference of Terms
Arc – The degree of bend for the curved portion of an pipe, tube or beam. Bevel - A type of end finishing for a pipe, tube or beam. Centerline Radius (CR) - Distance from the center of curve to the centerline axis of the pipe, tube or beam. Abbreviated as CLR. Cold Bending – Using cold shaping methods to bend a pipe or other object. Degree – An increment of angle to form a bend above the plane of 0 degrees, to which the bend is formed I. D.– The Inside diameter of the pipe or tube. Neutral Axis – The unbent portion of an object (pipe, tube or beam) that is neither compressed or under tension due to bend. O.D. – The Outside diameter of a pipe, tube or beam in inches. Out of Plane - The deviation from a horizontal plane of rectangular object by a single bend, between its tangent points and the centerline of the bend. Oval - The distortion of pipe or tube from it’s a circular shape caused by bending. Material Grade - Manufacturers' specification of material for pipe, tube or beam material, (i.e. A53B, T304W SS). Plain End - Square cuts made to a pipe, tube or beam prior to bending.
Roll Past – Degree or fraction of degree that a pipe, tube or beam is bent beyond a specified point. Rough Cut - Pipe, tube or beam end cuts that are not required to be straight. Square Cut – End cuts to a pipe, tube or beam that are square to the centerline of a bend after the bending process. Tangent - The straight portion of material on either side of arc of a bend. Tangent Point - A point where the bend of a pipe, tube or beam begins or ends. Taper Bore - A milling or grinding out of the inside diameter of the end of a bend to create a tapered pipe or tube diameter. Wall - The thickness in inches of the outside wall of a pipe or tube. Wrinkles - Ribbed or wavy indentations in the inner bend angle of a bend of a pipe, tube or beam.
