1.
Ram Style Bending:
Ram
style bending is the simplest and cheapest method of bending pipe
and tube.
 The
pipe or tube is restrained at two eternal points and the ram advances
on the central axis and deforms the pipe.
The
bent pipe or tube is prone to deformation on both the inside and
outside curvature. The pipe or tube is often deformed into an oval
shape depending on the wall thickness of the material.
This
type of bending is suitable for bending electrical conduit and
similar light gauge product.

2.
Rotary Draw Bending:
This
is the most commonly used style of bender for bending pipe and
tube where maintaining a good finish and constant diameter is
important
The
pipe or tube is drawn through stationary counter- bending die onto
fixed radius former die.
This
method of bending pipe and tube is perfect for handrail, Ornamental
iron work, Conduit Bending, Sand rail and kit car chassis, Stock
car chassis, Drag car chassis, Roll cages, Trailer frame bending
and many other types of pipe and tube bending.

Mandrel
Bending:
Mandrel
bending of pipe and tube is used where the bent pipe and tube are
to have absolutely the least amount of deformation possible.
The
pipe and tube is supported internally with a flexible mandrel
support that bends with the pipe or tube, and ensures that the
interior  is not deformed. The pipe or tube is drawn through a
counter bending die onto fixed radius former die, and the hole
process ensures the best possible bends.
Mandrel
bending of pipe and tube is used in the manufacture of exhaust
pipes, custom exhaust pipes, turbocharger exhaust and intake
tubing, dairy tubing and process tubing, heat exchanger tubing,
and all stainless and aluminum tubing where a non deformed
diameter finish is critical.

Ring
Roll Bending:
Ring
roll Bending is used for bending pipe and tube to large Center
Line Radius, i.e. to large circumferences.
Pipe
and tube ring roll benders comprise 3 rolls on separate shafts
that roll the pipe through the rolls while the top roller exerts
downward pressure on the top roll to deform the pipe.
Ring
Roll Pipe and Tube benders are available in 2 or 3 driven roll
machines, with either manual adjustment or hydraulic adjustment of
the top roll.
Roll
bending is typically used for awning manufacture, drum rolls,
frames for barbecues, and other round items with a large Center
Line Radius.
