Patent number: 8991439Abstract: A metal pipe of single piece construction including a wall formed of a single corrugated metal sheet. The sheet has opposing first and second edges extending longitudinally along the sheet. The wall includes a seam that is formed by abutting portions of the first and second edges. The seam extends helically about and along a length of the wall. The sheet has a cross-sectional profile defining 3 corrugation peaks at an exterior wall surface and 3 flat segments, wherein each corrugation peak is separated from an adjacent corrugation peak by a respective one of the 3 flat segments. The sheet has a flattened sheet width of approximately 27 inches and a finished sheet width of approximately 24 inches. The wall defines a pipe diameter of at least 96 inches.Type: GrantFiled: March 7, 2014Date of Patent: March 31, 2015Assignee: W.E. Hall Company, Inc.Inventor: Jordan Twist
