Welcome to this Swagelok how-to video
here's what you'll need to bend tubing
using a Swagelok
hand tube bender
A hand tube bender corresponding to the tubing size
a piece of tubing
a marker
a protractor is optional
A Swagelok hand tube bender
can be used to make consistent
high quality bends in tubing
made from most materials
the hand tube bender bends one eighth (1/8)
one-quarter (1/4), five sixteenths (5/16)
three-eighths (3/8)
and half (1/2) inch
and three (3)
Six (6), eight (8), ten (10)
and twelve (12) millimeter outside diameter tubing in a variety of wall thicknesses
the wall thickness requirements for one-quarter (1/4) inch stainless steel tubing
to be bent
using the hand tube bender
Are a minimum of zero point zero two eight (0.028) inches
or zero point seven one millimeters (0.71)
and a maximum of zero point zero six five (0.065) inches
or one point six five (1.65) millimeters for a hand tube bender
with a bend radius of nine sixteenths (9/16) inches
the tubing must be
fully annealed, high-quality seamless or welded and drawn
meeting ASTM A269
or A213 or the equivalent
with a hardness of 90 HRB
or 200 HB
this hand tube bender can be used to form single, offset and other bends
we will go through the procedure to make a ninety (90) degree bend
four (4) inches from the end of the tube followed by a hundred eighty degree (180) bend
with four inches between bends
for the ninety (90) degree bend
first place a reference mark at the end of the tube from which you are
beginning the measurements
measure four (4) inches from the reference mark and make a bend mark to indicate the first
Desired bend length
swing the short handle up so it is above the bender die
open the tube latch
place the tube in the groove of the bender die
with the reference mark to the left of the tube latch
close the tube latch over the tube
this restricts movement of the tube
but still allows for additional alignment
carefully lower the short handle until the roll dies rest gently on the tube
while keeping the link straight and parallel to the long handle
note that premature bending may occur if the link is not straight and parallel to
the long handle
Align the zero on the roll support
with the zero on the name plate
with the reference end of the tube to the left of the latch
align the bend mark with the mark on the roll support
that corresponds to the bend angle
L corresponds to ninety (90) degrees
slowly pushed the short handle down until the zero (0) on the roll support
reaches the ninety (90) degree mark on the name plate
note that the tubing will spring back slightly after the bend has been
completed
to adjust for spring back
Lift the bender handle and repeat the alignment of the tubing with the roll
support
then measure the bend with the bender scale
and bend an additional two or three degrees as needed
after completing the bend, swing the short handle up and away from the tube
pull the tube latch off the tube
and remove the tube from the bender groove
verify the bend angle using a protractor, template
or against a known angle to ensure the desired bend angle has been achieved
now for the hundred and eighty (180) degree bend Make a second bend mark four (4) inches
from the vertex of the ninety (90) degree bend away from the reference mark
place a directional mark over the bend mark
to indicate the outside or heel
of the hundred and eighty (180) degree bend
This will help insure the bend is made in the intended direction
place the tube in the groove of the bender die
with the reference mark to the left of the tube latch
close the tube latch
over the tube
this restrict movement of the tube
but still allows for additional alignment
carefully lower the short handle until the roll dies rest gently on the tube
while keeping the link straight and parallel to the long handle
note that premature bending may occur if the link is not straight and parallel to
the long handle
align the zero (0) on the roll support with the zero (0) on the name plate
with the reference end of the tube to the left of the latch
align the bend mark with the mark on the roll support that corresponds to
the bend angle
L corresponds to ninety degrees
slowly push the short handle down
Until the zero (0) on the roll support reaches approximately ninety (90) degrees on
the name plate
loosen the short handle from the clevis until the short handle will swing without
moving the roll support
swing the short handle up
until it is slightly above perpendicular to the long handle
retighten the short handle
this will provide continuous right angle leverage for the rest of the bend
continue the bend until the zero (0) on the roll support reaches the hundred and
eighty (180) degree mark on the name plate
after completing the bend, swing the short handle away pausing when the zero (0) on
the roll support reaches approximately ninety (90) degrees
loosen the short handle
Move it until parallel with the long handle
then retighten the short handle
move the short handle up and away from the tube
pull the tube latch off the tube
and remove the tube away from the bender groove
Verify the bend angle using a template
or against a known angle
to ensure the desired bend angle has been achieved
