The length of material along the centerline of the tubing
Distance in inches from the center of curvature to the centerline
axis of the tube bending or pipe bending bends. Abbreviated as
CLR. See Tube Bending and Pipe Bending Diagram
Angle in degrees to which the tube/pipe bends are formed (i.e. 45
degrees, 90 degrees, 180 degrees, etc.)
Bending of a rectangular tube with its short side in the plane of the
tube or pipe bend
Bending of a rectangular tube with its long side in the plane of the
tube or pipe bend
Inside diameter of the tube or pipe bends
The minimum straight on the end of pipe bends required by the
bending machine to form the bend
That portion of the pipe or tube that is neither in compression or
tension.
Outside diameter in inches of the tube or pipe
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
The distortion or flattening of pipe or tube from its normal, round
shape caused by the pipe bending process
Amount of degrees material will return after bending pressure is
released
The straight portion of material on either side of arc of bending
bends. See Tube Bending and Pipe Bending Diagrams.
The point at which the bend starts or ends. See Tube Bending
and Pipe Bending Diagrams.
The thickness in inches of tubular pipe bending material.
Waving or corrugation of pipe bending bends in the inner radius.
