External pipe coatings are used to protect the metal from corrosive environments (3LPE coated pipes are the most common choice). Internal lining (example PTFE) protects the pipe from corrosive fluids. Clad pipes (CRA) have the inner surface covered by higher grade materials to achieve stronger resistance while decreasing the overall pipe cost.

This creates a dangerous situation where small adjustments to the tool orientation can lead to large, unexpected rotary motions. There can be up to 180 degrees of rotary motion when the tool is only expected to move a short distance along the workpiece. The results can be disastrous for the part, the tool, or the milling machine.

is unity. This type of universal joint is normally referred to as either a Cardan or Hooke universal joint (Fig. 1). Placing two universal joints in tandem with proper phasing allows the velocity fluctuations of the first joint to be cancelled by the second joint, allowing for a constant output speed equal to the input speed.
