2. 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 ]

3. Cold-formed steel - Wikipedia

   en.wikipedia.org/wiki/Cold-formed_steel

   Welding is possible in cold-formed steel elements, but it shall follow the standards given in AISI S100-2007, Section E. 1.When thickness less than or equal to 3/16" (4.76mm): The various possible welds in cold formed steel sections, where the thickness of the thinnest element in the connection is 3/16" or less are as follows

4. Drawing (manufacturing) - Wikipedia

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

   The cold drawing process for steel bars and wire is as follows: Tube lubrication: The surface of the bar or tube is coated with a drawing lubricant such as phosphate or oil to aid cold drawing. Push Pointing: Several inches of the lead ends of the bar or tube are reduced in size by swaging or extruding so that it can pass freely through the ...

5. Tube (fluid conveyance) - Wikipedia

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

   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 characteristics as dependable weld integrity, dimensional accuracy, and an excellent surface finish.

6. Work hardening - Wikipedia

   en.wikipedia.org/wiki/Work_hardening

   Cold forming techniques are usually classified into four major groups: squeezing, bending, drawing, and shearing. Applications include the heading of bolts and cap screws and the finishing of cold rolled steel. In cold forming, metal is formed at high speed and high pressure using tool steel or carbide dies.

7. Accles & Pollock - Wikipedia

   en.wikipedia.org/wiki/Accles_&_Pollock

   Accles and Pollock was a leading British bicycle tubing manufacturer. Many leading bike builders in the UK during the 1930s, 40s and 50s preferred to use their tubesets as they were air hardening, which become stronger when brazed, unlike the manganese based Reynolds tube which is weakened by heating.
