Secop has changed most of its compressors to copper connectors to ensure easy brazing and handling.
Should additional extra handling or bending of connectors be required, it is the responsibility of the techni-
cian to choose the proper bending method. Bending is not recommended without the standard support tools
used for adjusting or bending normal tubes shown below.
The following tools may be used for bending.
Spring benders are an efficient low-cost method for bending copper tubes. They are available in different
sizes to fit over the copper tube. Please ensure that you choose the correct size. The spring must be placed
over the full length of the bend. If you have difficulties removing the spring after bending, do not use force to
pull on the spring, as this may damage the spring. Simply twisting the spring and “unscrewing” the spring
will usually work. This procedure is only recommended for small adjustments.
Lever-type benders are easy to use and are calibrated for accurate bending. Many have scales or markings
to repeat the bending accuracy.
In some cases, special bending tools are necessary
due to space issues or special angles. This requires
a special geometry to protect the tube against wear
and tear on the profile (effective flow diameter).
If you need further information, please get in contact
with a bending specialist.
