  Mandrel for hydraulically expanding a tube into engagement with a tubesheet - Patent 4159564
The mandrel also comprises passages disposed in the trailing end for inducing pressurized fluid between the grooves, whereby the pressurized fluid is contained between the seals, the membrane, and the tube to hydraulically expand the tube into engagement with the tubesheet.
The trailing end 11 of the mandrel has a portion 47 which is not coated or covered by a membrane or an electrically isolating material and through which electrical contact is made to the one lead of the eddy current coil 33.
The mandrels hereinbefore described may be utilized repeatedly to hydraulically expand tubes into engagement with the tubesheet and may be positioned very accurately with respect to the inner edge of the tubesheet resulting in the tubes being expanded into engagement with that portion of the tubesheet which is adjacent to the inner edge thereof.

 Method of breaking loose vulcanized hose from a rigid mandrel - Patent 4435351
Fluid pressure is thereafter introduced between the hose and the mandrel thereby causing the hose to increase in diameter and shorten in length, thus breaking the hose loose of its associated mandrel.
The mandrels are suitably lubed prior to construction of the hose thereon with compositions that are readily available and well known to those skilled in the art of hose manuafacture.
In this instance, fluid may be introduced between the exterior surface of the mandrel and the interior surface of the hose to be broken therefrom via the orifice, thus eliminating the need of inserting a hollow needle through the wall of the hose from its exterior.

 What is Mandrel Bending? at Van Sant Enterprises' Trick Tools.com
The mandrel actually goes inside the tube and is held by a mandrel rod to support the tube at the tangent point of the bend.
The type of mandrel required varies depending on the wall thickness of the tube, radius required, and type of material being bent.
Most chassis or frame tube bending applications do not require a mandrel and even though the bend may appear stronger the outer wall of the tube is actually stretched thinner by the mandrel bending process.

 Arrow Springs' Tips & Tricks - Using Sludge Mandrel Release
Sludge™ mandrel releases give superior holding strength to the tugging and twisting rigors of even the most aggressive beadmaker, yet the bead easily twists off when it cools.
A mandrel with a very thin coating is harder to remove.
Near the bead holes where the mandrel release never became red hot, the mandrel release will be strong while hot and stay strong even when cool.

 Breakaway mandrel for transporting disks patent invention   (Site not responding. Last check: )
Dimensional instability of the plastic material of the one-piece mandrel, as well as the flexure of the mandrel, may be a major factor in the accuracy of the placement of disks into the pallet.
Using a mandrel having a different number of slots than the disk lot size causes the lots to be broken up and disordered during a transfer process.
The mandrel comprises a longitudinally extending rigid core and a sleeve having a bore through which the core extends when the sleeve and the core are in an assembled position.

 FordMuscle Webmagazine: Project MX, Flowmaster Universal Mandrel Bent Dual Exhaust
As opposed to the very common "empty" or "crush" bending technique, a mandrel bent exhaust retains a common inside diameter throughout the bends.
Mandrel bending can create a bend much tighter than empty bending and also improves the appearance of the finished exhaust.
Mandrel bending is especially suited for automotive exhaust applications where a complete over-the-axle system can make for some sharp turns.

 Enjoy The Drive -- What 'Mandrel Bent' Means
"Mandrel bending is when a set of balls, called a mandrel, is inserted into the pipe during bending.
These balls are positioned and pulled through the pipe so that the bends are not deformed and maintain a close-to-perfect shape throughout the length of the bend.
The pros are that the tube can be bent on a much tighter radius and still flow well due to the pipe being round and not collapsed.

 CES - Mandrel Bending Services
Mandrel bent pipes reduce backpressure by up to 35% when compared to pressure bent pipes of the same nominal pipe diameter.
Mandrel bending is a process in which the tubing is supported from the inside by a mandrel during the pressure assisted bending process, this allows the steel to stretch on the outside of the bend and compress on the inside of the bend.
Mandrel bent pipes have a consistent flow area of 3.14 square inches to maximize exhaust flow.
