Two new developments in fabricating corrugated metal pipe (CMP), plus a study of changes in the corrugation configuration, result in a better finished product than that which has been produced by the riveting method. The lockseam method, which produces continuous corrugated pipe from coil stock in a variety of depths and pitches in the corrugation, reduces the leakage factor to a greater extent than does the lapseam riveting method. The spotweld method, as now used, has shown greater seam strengths. The study of new coatings to replace or improve present bituminous coatings, and the ability to develop greater strengths in lighter gage material by the changing of corrugation configuration, will expand the use of CMP in the irrigation field, as well as in other fields.
