Helically wound metal pipe with sealing arrangement
A pipe includes a tubular pipe formed of a metal sheet that is spirally wound such that opposite edges of the metal sheet are joined by a crimped lock seam that extends helically along a length of the tubular pipe. A sealing arrangement includes a helically extending worked surface band extending along the crimped lock seam and to both sides of the crimped lock seam, the worked surface band having a surface roughness that is greater than a surface roughness of unworked surface portions outside of the worked surface band. A helically extending external coating band is applied over the crimped lock seam and bonded to the worked surface band.
