Phraseology
Pipe or Tube Mfg. – NOC & DriversDescription
Code 3022 applies to employers engaged in manufacturing non-ferrous metal pipes or tubes. The common non-ferrous metals that are used in this manufacturing process are aluminum, brass or copper. The non-ferrous metals are reduced to a molten state by means of an electric or gas-fired melting furnace. The resulting metal billets are then rolled and/or spun in rolling machines for which a pipe or tube is drawn. The tubing may run through a furnace for annealing purposes. After the material is heated to a pliable condition, it may be sent through an extruding machine that uses dies to produce various forms of pipes or tubes.
