| Degree
– An increment of angle to form a bend above the plane of
0 degrees, to which the bend is formed (i.e. 10, degrees, 45 degrees,
90 degrees, 180 degrees, etc.) See Diagram
Easy
Way (EZ) - Bending of a rectangular pipe, tube or beam
along its shortest dimension of length.
Hard
Way (HW) - Bending of a rectangular pipe, tube or beam
along its thickest dimension of length.
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.
Ovality
- 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. |
