Overview of Mechanical Properties

Arconic aluminum alloy drill pipe is extruded in Arconic’s Lafayette, Indiana facility, one of the largest and most advanced extrusion mills in the world.
The Arconic method of extrusion provides a variety of benefits:
  • Offers a seamless aluminum alloy tube with integral heavy ends of attachment of the tool joint
  • Body and heavy ends of each tube are extruded in one singular operation. No further upsetting is required
  • Offers very smooth internal and external surfaces, excellent concentricity, precise wall thickness, and near-perfect section shapes
