2. Cold-formed steel - Wikipedia

   en.wikipedia.org/wiki/Cold-formed_steel

   Cold-formed steel, especially in the form of thin gauge sheets, is commonly used in the construction industry for structural or non-structural items such as columns, beams, joists, studs, floor decking, built-up sections and other components. Such uses have become more and more popular in the US since their standardization in 1946.

3. Tube (fluid conveyance) - Wikipedia

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

   There are three classes of manufactured tubing: seamless, [1] as-welded or electric resistant welded (ERW), and drawn-over-mandrel (DOM). Seamless tubing is produced via extrusion or rotary piercing. Drawn-over-mandrel tubing is made from cold-drawn electrical-resistance-welded tube that is drawn through a die and over a mandrel to create such ...

4. 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 ...

5. Structural steel - Wikipedia

   en.wikipedia.org/wiki/Structural_steel

   EN10219-1 specifies the technical delivery conditions for cold formed welded structural hollow sections of circular, square or rectangular forms and applies to structural hollow sections formed cold without subsequent heat treatment. Requirements for S275JOH pipe tolerances, dimensions and sectional s275 pipe properties are contained in EN 10219-2.

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 ]

7. Pipe (fluid conveyance) - Wikipedia

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

   Aluminum pipe or tubing may be utilized where iron is incompatible with the service fluid or where weight is a concern; aluminum is also used for heat transfer tubing such as in refrigerant systems. Copper tubing is popular for domestic water (potable) plumbing systems; copper may be used where heat transfer is desirable (i.e. radiators or heat ...

8. 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.

9. Cold working - Wikipedia

   en.wikipedia.org/wiki/Cold_working

   In metallurgy, cold forming or cold working is any metalworking process in which metal is shaped below its recrystallization temperature, usually at the ambient temperature.. Such processes are contrasted with hot working techniques like hot rolling, forging, welding, etc. [1]: p.375 The same or similar terms are used in glassmaking for the equivalents; for example cut glass is made by "cold ...
