Pro-Tech Automotive supplies a selection of Mandrel bent tubing at various degrees
Mandrel bends being the ultimate choice of bends for non-restrictive flow through
conventional pipe bending.
The Mandrel consists of a shaft with 3 movable spheres/balls, these balls insert inside
the tubes from collapsing when the bend is formed, this making it
easier to cut
sections on the arc/bend
and rejoining these ready for welding.
The machine we will be using to create these various bends is Ercolina Mandrel
Bender, therefore allowing me
to bend to any angle requested.
