Abstract
An erosion resistant frac head with a convergence chamber, an expansion chamber and a mixing chamber provides improved resistance to erosion caused by abrasive frac fluids pumped through the frac head. A bottom leg of the erosion resistant frac head may be replaced in the field by field hands. Top entry ports of the frac head may also be replaced in the field by field hands.
