  • Pipe or the like, a female end ring, and a method of manufacturing such a pipe or the like
    Patent number: 6854770
    Abstract: A pipe formed from a concrete cylinder has an end ring with a ferrule which can be snuggly mounted on one end of the pipe and a skirt axially adjacent to the ferrule for receiving a mail endpiece of another pipe. The ferrule is expanded as it is mounted on the cylinder and exerts a compressive force against the outer peripheral face of the cylinder for forming a secure seal. A rib may be disposed on an inner annular surface of the ferrule and an adhesive may be applied for enhancing the seal between the cylinder and the ferrule.
