  2. Tube (fluid conveyance) - Wikipedia

    en.wikipedia.org/wiki/Tube_(fluid_conveyance)

    A tube, or tubing, is a long hollow cylinder used for moving fluids (liquids or gases) or to protect electrical or optical cables and wires. The terms " pipe " and "tube" are almost interchangeable, although minor distinctions exist — generally, a tube has tighter engineering requirements than a pipe.

  3. Drawing (manufacturing) - Wikipedia

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

    For wire, bar, and tube drawing, the starting stock is drawn through a die to reduce its diameter and increase its length. Drawing is usually performed at room temperature, thus classified as a cold working process; however, drawing may also be performed at higher temperatures to hot work large wires, rods, or hollow tubes in order to reduce ...

  4. Cold welding - Wikipedia

    en.wikipedia.org/wiki/Cold_welding

    Cold welding or contact welding is a solid-state welding process in which joining takes place without fusion or heating at the interface of the two parts to be welded. Unlike in fusion welding, no liquid or molten phase is present in the joint. Cold welding was first recognized as a general materials phenomenon in the 1940s.

  5. Metal bellows - Wikipedia

    en.wikipedia.org/wiki/Metal_bellows

    deep drawn tubes for bellows Metal bellows. There are three main types of metal bellows: formed, welded and electroformed. Formed bellows are produced by reworking tubes, normally produced by deep drawing, with a variety of processes, including cold forming (rolling), and hydroforming. They are also called convoluted bellows or sylphons.

  6. Tube drawing - Wikipedia

    en.wikipedia.org/wiki/Tube_drawing

    Tube drawing is a process to size a tube by shrinking a large diameter tube into a smaller one, by drawing the tube through a die. This process produces high-quality tubing with precise dimensions, good surface finish, and the added strength of cold working . [ 1 ]

    A general note applies generally and is not called out with flags. 2. Find number: "FN" meaning "find number" refers to the ordinal number that gives an ID tag to one of the constituents in a parts list (list of materials, bill of materials). Thus "fasten using FN7" refers to a fastener that is "find number" 7 in the list. FoS: feature of size
