  2. Tube bending - Wikipedia

    en.wikipedia.org/wiki/Tube_bending

    An induction coil is placed around a small section of the pipe at the bend point. It is then induction heated to between 800 and 2,200 degrees Fahrenheit (430 and 1,200 C). While the pipe is hot, pressure is placed on the pipe to bend it. The pipe can then be quenched with either air or water spray or be cooled against ambient air.

  3. Bending - Wikipedia

    en.wikipedia.org/wiki/Bending

    In the absence of a qualifier, the term bending is ambiguous because bending can occur locally in all objects. Therefore, to make the usage of the term more precise, engineers refer to a specific object such as; the bending of rods, [2] the bending of beams, [1] the bending of plates, [3] the bending of shells [2] and so on.

    A press brake bending a sheet of steel. A press brake is a type of brake, a machine used for bending sheet metal and metal plate. [1] It forms predetermined bends by clamping the workpiece between a matching top tool and bottom die. [2] Bending process A high-tonnage hydraulic press brake Liwei CNC 2000T 12M Heavy Duty model

  5. Bend radius - Wikipedia

    en.wikipedia.org/wiki/Bend_radius

    Bend radius, which is measured to the inside curvature, is the minimum radius one can bend a pipe, tube, sheet, cable or hose without kinking it, damaging it, or shortening its life. The smaller the bend radius, the greater the material flexibility (as the radius of curvature decreases, the curvature increases). The diagram to the right ...

  6. Tube beading - Wikipedia

    en.wikipedia.org/wiki/Tube_beading

    Tube beading is a metal forming process that forms a bead on the end of a tube. Tube beads can be used to help hold a hose on the end of a tube or to strengthen the end of the tube. [ 1 ] There are two forming processes: internal roll forming and ram forming .

  7. Four-point flexural test - Wikipedia

    en.wikipedia.org/wiki/Four-point_flexural_test

    Values for the flexural strength measured with four-point bending will be significantly lower than with three-point bending., [7] Compared with three-point bending test, this method is more suitable for strength evaluation of butt joint specimens. The advantage of four-point bending test is that a larger portion of the specimen between two ...
