Hard Way (HW) - Bending of a rectangular tube with its Iong side in
the plane of the tube or pipe bend
I.D. - Inside diameter of the tube or pipe bends
Minimum Tangent - The minimum straight on the end of pipe bends
required by the bending machine to form the bend
Neutral Axis - That portion of the pipe or tube that is neither in
compression or tension.
O.D. - Outside diameter in inches of the tube or pipe
Out of Plane - The deviation of the horizontal plane of a single pipe
bend between its tangent points. based on the theoretical center-line
of the pipe bend
Ovality - The distortion or flattening of pipe or tube from its normal,
round shape caused by the pipe bending process
Spring back - Amount of degrees material will return after bending
pressure is released
Tangent -The straight portion of material on either side of arc of
bending bends. See Tube Bending and pipe Bending Diagrams.
Tangent Point - The point at which the bend starts or ends. See
Tube Bending and Pipe Bending Diagrams.
Wall - The thickness in inches of tubular pipe bending material.
Wrinkles - Waving or corrugation of pipe bending bends in the inner
radius
