3. Pipe bursting - Wikipedia

   en.wikipedia.org/wiki/Pipe_bursting

   The transition from the leading end to the trailing end can include "fins" that make first contact with the existing pipe. Using these fins as the primary breaking point is a very effective way to ensure that the pipe is broken along the entire circumference. A machine is set in the receiving pit to pull the expander head and new pipe into the ...

4. Tube bending - Wikipedia

   en.wikipedia.org/wiki/Tube_bending

   Tube bending is any metal forming processes used to permanently form pipes or tubing. Tube bending may be form-bound or use freeform-bending procedures, and it may use heat supported or cold forming procedures. Form bound bending procedures like “press bending” or “rotary draw bending” are used to form the work piece into the shape of a ...

5. Bending (metalworking) - Wikipedia

   en.wikipedia.org/wiki/Bending_(metalworking)

   Bending A chimney starter, a sample product of bending. Bending is a manufacturing process that produces a V-shape, U-shape, or channel shape along a straight axis in ductile materials, most commonly sheet metal. [1] Commonly used equipment include box and pan brakes, brake presses, and other specialized machine presses.

6. Hydroforming - Wikipedia

   en.wikipedia.org/wiki/Hydroforming

   In tube hydroforming pressure is applied to the inside of a tube that is held by dies with the desired cross sections and forms. When the dies are closed, the tube ends are sealed by axial punches and the tube is filled with hydraulic fluid. The internal pressure can go up to a few thousand bars and it causes the tube to calibrate against the dies.

7. Die (manufacturing) - Wikipedia

   en.wikipedia.org/wiki/Die_(manufacturing)

   A die is a specialized machine tool used in manufacturing industries to cut and/or form material to a desired shape or profile. Stamping dies are used with a press, [1] as opposed to drawing dies (used in the manufacture of wire) and casting dies (used in molding) which are not. Like molds, dies are generally customized to the item they are ...
