When compared to rigid pipe,
hydraulic tubing offers the
following advantages:
1. Size for size, tubing is lighter in
weight, easier to handle and
can be bent more easily than
iron pipe.
2. Bent tubing reduces pressure
drop and turbulence in the
system because it eliminates
sudden change in the direction
of the fluid flow.
3. Hydraulic tubing reduces
the number of connections
required, thus reducing
material and labor costs.
4. Fewer joints means lower costs
and fewer points of potential
leakage.
5. The use of tube fittings makes
every joint a union which
permits easier,
faster maintenance and repair
work.
6. The ORS-TF Tube Fitting
eliminates the need for
threading, brazing or welding.
Tube bending
Tube routing
and installation
Inspect the tubing to see that
it conforms to the required
specifications before installation.

To reduce the number of fittings
in a tube assembly, bend the
tubing whenever possible.
Steel tubing can be bent in many
sizes by using a hand bender
designed for steel tubing. For
production quantities, or for larger
sizes, a power bending tool is
generally used.
Contact Danfoss for additional
tube bending information.
Tubing manufacturers will advise
the correct radii for various types
and wall thicknesses of tubing.
Kinks, flattened bends, wrinkles
and tube breakage can be
avoided by the use of proper tube
bending equipment.
Avoid straight line connections
whenever possible, especially in
short runs.
Fluid conveying systems (see
figures 2, 3 and 4) should be
designed to follow the contour
of the equipment. They are easier
to install and present a neater
appearance. Long runs should be
supported by brackets or clamps.
All heavy systems components
should be bolted or clamped to
eliminate tubing fatigue.

Tubes should align with the
center line of the fittings,
without distortion or tension.
Tubing should not be sprung
into position (see figure 1) to be
assembled to the fitting. If this
occurs the tubing has not been
properly fabricated, and when
installed and connected, places
the tubing under stress.
