| 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. |
