Cladding

Double-composite tubes add new features not available with single-metal tubes. Note the following before inquiry:

  • Combination of materials
  • Dimensions and tolerance
  • Mechanical characteristics and physical properties
  • Other specifications
    — processing conditions, operating environment

Specialized Drawing

In drawing, material is stretched by passing it through dies at room temperature. Wires, rods, or pipes have sections reduced while the sectional shape — cylindrical, hexagonal, square, or other — is changed. 

Drawing requires cold drawing to ensure excellent inner and outer surface finishing not obtainable through hot-process finishing such as by hot rolling or hot extrusion. Extruded materials are often used for drawing, but drawn tubes and rods have higher dimensional accuracy than extruded materials.
