Description
All rods are straightened and inspected by Eddy Current/magnetic for surface defects. Both ends are upset by automatic high-speed hot forging. Rods are full length normalized to relieve residual stresses, air-quenched, and tempered to refine and homogenize grain structure, and surface nor peened to remove any remaining heat treat scale. All rods are with longer fatigue life. Upset pin blanks are machined and dimensions gauged. Pin threads are cold-formed to strengthen the thread from fatigue. An inhibitor lubricant is applied to each pin and a thread protector is installed. An oil-soluble coating protects rods from atmospheric corrosion in storage. All rods are bundled to prevent handling damage during transportation to the well location. Quality control inspections are performed at each step of the manufacturing process.
