Hydraulic mandrel tube benders combine the bending power of hydraulics with the support of mandrel bending.
Mandrel pipe benders are often used to help prevent some of the most common bending problems. Things like wrinkles though the bend, buckling, and kinks can be avoided when properly using a mandrel during the bending process. This is because the pipe is pulled over the mandrel before bending and the mandrel is held in a fixed position as the pipe is bent. The mandrel provides support to the pipe and holds it firmly in the groove of the bend die.
When combined with the bending power of a hydraulic bender, a hydraulic mandrel tube bender is an excellent solution for heavy-duty bending.
A hydraulic mandrel bender uses either air, or electric activated pumps to perform the bend while the mandrel provides support to the pipe through out the bend. With this type of bender, heavy duty pipes can both be bend and supported so that the finished bend meets specifications without any of the common problems like wrinkles.
